2 Complete the passage with the words below to learn about bias-free language.
Like humans, language tends to carry biases, which can lead to discrimination. Academic writing needs to be objective and scientific: neither gender should be preferred. Historically, writing has reflected a bias towards males such as the words _________ and postman. Now, writers are more careful. Many words that included man have been replaced. For example, police officer is used instead of __________, ___________ instead of chairman, salesperson _________, humankind instead of _________ and postal worker instead of _________. The title Ms is used for women instead of Miss or Mrs, since it does not show whether a woman is married or not.
chairman mankind policeman chairperson postman salesman
chairman
policeman
chairperson
salesman

4 List some environmental problems and their causes. Then write down solutions to each problem.
EXAMPLE
Many animals and plants are endangered due to loss of habitat. To solve the problem, some measures must be taken to protect them. Cuting down trees without permission should not be allowed. Forests should be well looked after …
Air pollution is a big problem, due to coal power plants and car emissions. To solve this problem, the building of coal power plants should be severely limited and those that already exist should be equipped with devices which clean the smoke they produce. Cars should also have very high emissions standards and should be kept from being driven in large cities when the pollution is bad.
A lack of green spaces in large cities is a problem due to overbuilding and overuse of concrete. To solve this problem, new construction should be limited, and when a company wants to build a new building it should be forced to include some green spaces in their designs. When roads are constructed or repaired, a grass strip should be included in the design, and trees should be planted on either side of the road. Finally, a survey could be made of unused property in the city, and some of this property could be purchased and made into public parks.
Reading, Listening, and Acting
1 Before listening to a TV show called The Evos, read the following introduction and then discuss the questions in pairs.
1 Where do you think the meteors came from
2 Why do you think the friends fell asleep
Previously on The Evos: A breaking news report tells of seven meteors hitting each of the seven continents, as revealed by a scientist called Dr Evo. Meanwhile, three friends, Seb, Anie, and Laura are cycling through woods near their homes. After seeing a flash of light, they follow it. They discover a hole with a strange glowing rock inside. The news on Seb’s radio is talking about the meteors, so they realise this must be one of them. Seb says they should take a closer look. As he gets closer, he suddenly falls asleep, and as the others go to help him, they also fall asleep. They awake at dusk to the sounds of men searching for the meteor. They escape and agree to see each other at school the following day, as well as promising not to tell anyone. Some men, dressed in black protective suits, take the meteor away ….
I think the meteors came from a far galaxy and certain some sort of alien life.
Maybe the alien was hising in the meteor and it used something to make them alseep to prevent itself from being seen.
2 Now listen to the start of the new episode and match the abilities to the character.
Seb can move things with his/her mind
Laura can stop time
Arnie can move from one place to another
Dr Evo can make himself/herself disappear
3 Listen to the episode again and write down the words and phrases that have the following meanings and functions.
1 mentioning something they almost didn’t remember to say ___________________
2 wanting to talk about something different quickly ___________________
3 saying the same thing in a different way than before ___________________
4 talking about the most important point ___________________
5 adding another point to something already said ___________________
before I forget\I nearly forgot
just to change the subject for a moment
in other words
first of all\above all
furthermore
4 In groups, act out a scene from The Evos using the instructions below.
1 Discuss what happens next in the scene. Use the following questions to help you make a script. The scene only needs to be a few minutes long.
What happens to the characters after they meet Dr Evo
Do the men in black also have powers
How do the characters use their powers
2 Decide who will play each character. Choose a narrator to help the audience understand what is happening.
Dr Evo Seb Arnie Laura Narrator
Men in black suits Any other new characters you want to add
Laura: Where are we going, Dr Evo
Narrator: Dr Evo doesn’t respond. Laura looks at her friends. They look back at her, concerned. After a while, they arrive at the hidden location.
Dr Evo: Great. We have arrived. Please come into this room. All will be explained shortly.
Narrator: The friends go into the room. Suddenly, Dr Evo disappears, and the door slams shut behind them.
Arnie: Hey! What’s going on here
Seb: Let us out, man!
Dr Evo: Ha ha ha! You really thought I was a friend No! I want to use your powers. I can use your powers to take over the whole world!
Laura: But what about the men in black Aren’t they dangerous They're coming for us all!
Dr Evo: Oh no, no no. You have misunderstood. Actually, they work for me. They do not have any special powers, but they help carry out my experiments…..
Laura: Why you rotten little ...
Seb: (whispers) Laura! You can move things with your mind, right Can you try opening this door for us (whispers) I think so ... but it’s not going to be easy ...
Seb: (whispers) Don’t worry. We will buy you some time.
Narrator: So, while Laura uses her powers to open the door, Seb and Arnie distract Dr Evo. They get him to talk about himself—since that's what he loves to do the most! Finally, the door opens!
Seb: Arnie! Stop time now and get us out of here before more of his goons come! Right!
Narrator: Arnie stops time. If he is touching others, they will also stop time too, so all three can move at the same time. Using this power, they escape and run away. They now must go into hiding and make sure Dr Evo and his men in black team don't ever find him. Tune in next week for the next thrilling episode!
Reading and Writing
1 Look at the picture. What do you think is inside the cave Do some research about our planet to find the answers to the following questions.
How old is the earth
What is the structure of the earth
How deep is the earth’s crust
What is at the centre of the earth
What is the deepest cave ever found
I think the cave is probably empty, but it is really hard to tell without going in and exploring it.
The earth is thought to be 4.5 billion years old. It has five layers: crust, outer mantle, inner mantle, outer core, and inner core. The crust is 8 km to 70 km thick and made mostly from rocks. The mantle is both solid and fluid. At the very centre of the earth, there is the inner core, which is thought to be made up mostly of iron and nickel, and which is solid. The deepest cave on the earth is the Veryovkina Cave in the country of Georgia, which is at least 2,212 metres deep.
2 Read part of a story about an amazing journey to the centre of the earth by famous writer Jules Verne. Underline the words that describe the unusual environment the explorers discover. What natural environments does it remind you of
vast lake or even an ocean; shore was lined with shining sand; a huge rock wall that was being worn away by the endless action of the waves; lit up by a strange light; vast clouds; a tall dense forest, composed of trees formed like umbrellas; mushrooms in their thousands, and each at least thirty feet high.
The scene reminds me of a strange beach in the far north, where it is not cold enough to have ice or snow in the summer, but where there is very little life.
JOURNEY TO THE CENTRE OF THE EARTH
During the interview,
What questions would you like to ask them ？
1.At first I could hardly see anything. After so long descending deep into the earth through dark, narrow caves, my eyes were not used to the light. But when I could focus again, I stood amazed.
2."It's a...sea!"I cried.
3.“Yes, Axel,"my uncle replied,"and I shall give it my name,as it was discovered by me！"
4.A vast lake or even an ocean, spread far beyond where the eye could see. The shore(海岸)was lined with shining sand, and was being softly lapped by waves. It was covered with small shells(贝壳) which were once inhabited by the first living beings. Around this sea stood a huge rock wall that was being worn away by the endless action of the waves.
5.I could see far over this great sea because it was being lit up by a strange light. Not sunlight, of course, as we were deep below the surface. No; with its bright, clear whiteness, the light must have been electric. Under the "sky", if it could be called so, being made of rock, were also vast clouds. They were being illuminated by this light, but the light gave no heat, so the place felt rather gloomy. Here we were, shut up inside a cave of a size that could not be estimated. It must have been several miles high.
6.Human words cannot describe the discoveries of those who have been deep into the earth. My imagination was powerless before such wonders. I felt like I was on some distant planet, and was both amazed and rather scared. However, I was energised by the breezy salty air supplying more oxygen to my lungs. After many days in much narrower spaces, it was a great relief.
7."Ready to walk a little now "asked my uncle.
8."Yes, certainly."
9."Well, let us follow the shore then,"he said, and we began to explore.
10.Soon in front of us appeared a tall, dense forest, composed of trees formed like umbrellas. "Mushrooms!" said my uncle. And he was right! There were mushrooms in their thousands, and each at least thirty feet high.
11."Wonderful!"cried my uncle. "A botanist never had such a feast as this! Now look under your feet."
12."Oh yes!" I exclaimed.
13.I hadn't noticed the many bones, which were being crushed under our feet as we walked. Suddenly I thought, if once these monsters lived here, might some still roam through these gloomy forests I anxiously surveyed the landscape, but we were the only living creatures in this subterranean world. Thankfully!
14.Eventually we returned to the cave we had entered from, and I fell asleep with strange thoughts. Where did this underground sea end Where did it lead to
How did they get to the center of the earth

Two explorers, Aexl and his uncle, have made a journey to the centre of the earth.
Through the dark, narrow caves to the center of the earth, they saw a vast sea. The shore was lined with shining sand and covered with smile shells. Around the sea stood a huge
rock wall . Strange light lit above the sea, illuminating the vast clouds. Seeing so, they felt both amazed and rather scared. Soon in front of them appeared a tall, dense mushroom forest in their thousands and each at least thirty feet high and underfoot were many bones. Thus, they felt wonderful but anxious as well.
The discoveries were described as amazing and scary. Aexl and his uncle said the thrill of discovering new things can always be a powerful motivator.

Giant Underground Ocean Found!
Today, explorers Peter David and his uncle Steven Winston announced that they had discovered a huge underground ocean while they were exploring a cave in the country of Georgia. David and Winston were on an expedition to find the bottom of the cave. It took them three weeks to pass the previous lowest point in the cave, which is 2,197 metres below the entrance. The two climbers then found a small side passage which they had to crawl through on their stomachs. After more than 200 metres, this passage opened up to a large room that contained a vast ocean of salt water. High above them was a light which must have been electric in nature. Along the shore were tall trees which looked like umbrellas. These were actually mushrooms. As they walked along the beach, they found many bones. However, they could see no living animals. After exploring the shores of the ocean for some time, they had to return to the surface as their supplies were running low. When asked how old the ocean was, Winston replied that it looked nearly as old as the earth itself, which is 4.5 billion years in age. Winston then went on to say that they intended to go back to the cave next year with more supplies and some small boats. “We are far from done with exploring this cave,” Winston said. “The earth’s crust is anywhere from 5 to 70 kilometres deep, but we’ve only gone down two kilometres. There is much more left to discover down there.”

SCIENCE FICTION OR SCIENCE FACT
Science fiction is one of the most popular genres of film. Showing us everything from alien worlds to intelligent robots and time travel, sci-fi films are extraordinary. But how much of this science fiction is also scientific fact Many sci-fi films are based on fiction: novels, short stories, or comics, which first came from someone’s imagination and were often influenced by earlier sci-fi works. However, some films try to make the science they show as realistic and accurate as possible.
The film Interstellar was a box-office success and was praised for how space travel and other scientific aspects of the plot were represented. The story takes place in the near future when living conditions on Earth threaten the survival of humanity. A brave team of astronauts and scientists begin a dangerous mission to find a new planet for humans to live on. Director Christopher Nolan wanted the film to be as realistic as possible. “Why simply imagine things that might happen in space or on an interstellar journey Why not actually look at the real science there ” he said. To make sure as much of the film as possible was grounded in real science, Nolan and his team were helped from the start by physicist Kip Thorne, an expert on Albert Einstein’s theories. Thorne provided the correct mathematics for the special effects team to generate the fantastic computer simulations that are seen in the film.
科幻小说还是科学事实
科幻小说是最流行的电影类型之一。向我们展示了从外星世界到智能机器人和时间旅行的一切，科幻电影是非凡的。但这些科幻小说有多少也是科学事实呢？许多科幻电影都是根据小说改编的: 小说、短篇小说或漫画，它们最初来自于某人的想象，往往受到早期科幻作品的影响。然而，一些电影试图使他们展示的科学尽可能真实和准确。
电影《星际穿越》在票房上获得了成功，并因为太空旅行和其他科学方面的情节表现而受到赞扬。故事发生在不久的将来，地球上的生活条件威胁着人类的生存。由宇航员和科学家组成的勇敢团队开始了一项危险的任务，即寻找一个新的星球供人类居住。导演克里斯托弗·诺兰希望电影尽可能写实。“为什么只是简单地想象可能在太空或星际旅行中发生的事情呢？为什么不看看真正的科学呢 ”他说。为了确保影片尽可能多地基于真实的科学，诺兰和他的团队从一开始就得到了物理学家基普 · 索恩的帮助，他是阿尔伯特 · 爱因斯坦理论方面的专家。索恩为特效团队提供了正确的数学方法，以生成电影中出现的奇妙的计算机模拟。
In the real world, the search for other habitable planets has been underway for many years. Space telescopes can identify planets orbiting stars by small changes in the stars’ light as the planets pass by. These searches have discovered countless planets. The next challenge is to find one that is neither too hot nor too cold, where there is water necessary for life forms to develop. Then the oroblem is how we would get there. As these stars and planets are many light years away, it would take hundreds or thousands of years to reach them. Creating a spaceship that could travel at the speed of light would be one option, but in the film, Earth does not have that much time and a quicker route must be found. Thus the problem to be overcome is time itself.
Again, real science provided an answer, which was then brought to the screen in the film. As Einstein famously described, time and space are not two separate things, but exist like a fabric that our universe is made of, called “space-time”. Objects such as planets and stars bend this fabric, creating the force we know as gravity. When this force is very large, space-time is bent a great deal, making it possible for a short cut, known as a “wormhole”, to appear. This would allow one to pass from one point in the universe to another without having to cross the space in between, therefore making the journey much quicker. Wormholes are often used in sci-fi stories, appearing as simple holes to pass through, but what would one actually look like Science tells us it would actually look like a sphere, through which we could see through to the other side, and so this is how it appears in the film.
在现实世界中，寻找其他可居住行星的工作已经进行了很多年。太空望远镜可以通过行星经过时恒星光线的微小变化来识别围绕恒星运行的行星。这些搜索已经发现了无数的行星。下一个挑战是找到一个既不太热也不太冷的地方，那里有生命形式发展所必需的水。那么问题是我们如何到达那里。由于这些恒星和行星距离我们很多光年，我们需要数百或数千年的时间才能到达它们。创造一艘可以以光速飞行的宇宙飞船是一种选择，但在电影中，地球没有那么多的时间，必须找到一条更快的路线。因此，需要克服的问题是时间本身。
再一次，真正的科学提供了一个答案，这个答案随后在电影中被搬上银幕。正如爱因斯坦著名的描述，时间和空间并不是两个独立的东西，而是像我们的宇宙构成的一个结构一样存在，被称为“时空”。诸如行星和恒星之类的物体弯曲了这种结构，产生了我们所知的引力。当这种力量非常大时，时空会发生很大的弯曲，使得一条被称为“虫洞”的捷径出现成为可能。这将允许一个人从宇宙的一个点到另一个点，而不必穿越中间的空间，因此使旅程更快。虫洞在科幻小说中经常被使用，看起来像是简单的穿越孔，但实际上虫洞是什么样子的呢？科学告诉我们它实际上看起来像一个球体，通过它我们可以看到另一边，这就是它在电影中的样子。
In the film, such a “wormhole” mysteriously appears near Saturn. Several astronauts have already been through, with some reporting back on promising planets they have found. The team travels through it to another galaxy in the hope of finding a new home. However, as hours pass on these distant planets, many years pass on Earth. This is also a realistic depiction of what such interstellar travel would be like, as described by Einstein’s theory of relativity. Time moves differently depending on where you are and whether you are still or moving.
Of course, sometimes real science has to be ignored to make sure that a film, which is only a few hours long, is entertaining and that viewers understand what they see. We cannot know exactly what interstellar travel looks like, but science can give us a good idea. Often, there is a fine line between science fiction and fact, which is always changing as science and technology progress. Things that were only being dreamed of years ago are now part of our everyday lives, such as the Internet, mobile phones, and soon even space travel itself. This is what continues to make sci-fi so exciting and popular, inspiring generation after generation to imagine our future existence.
在影片中，这样一个“虫洞”神秘地出现在土星附近。一些宇航员已经通过，一些报告回到他们已经发现的有希望的行星。研究小组穿越它到达另一个星系希望能找到一个新家。然而，随着时间在这些遥远的行星上流逝，在地球上也流逝了许多年。正如爱因斯坦的恆星际旅行相对论所描述的那样，这也是对这种情况的现实描述。时间的流逝取决于你所在的位置以及你是静止的还是移动的。当然，有时候真正的科学必须被忽略，以确保一部只有几个小时长的电影是娱乐性的，并且观众理解他们所看到的。我们不能确切地知道恒星际旅行是什么样子，但科学可以给我们一个好主意。通常，科幻小说和事实之间有一条细微的界限，这条界限随着科学技术的进步而不断变化。多年前我们只能梦想的东西现在已经成为我们日常生活的一部分，比如互联网、手机，很快甚至太空旅行本身。这就是为什么科幻小说如此令人兴奋，如此受欢迎，激励着一代又一代人去想象我们未来的生活。

EXAMPLE
Many animals and plants are endangered due to loss of habitat. To solve the problem, some measures must be taken to protect them. Cuting down trees without permission should not be allowed. Forests should be well looked after …
Air pollution is a big problem, due to coal power plants and car emissions. To solve this problem, the building of coal power plants should be severely limited and those that already exist should be equipped with devices which clean the smoke they produce. Cars should also have very high emissions standards and should be kept from being driven in large cities when the pollution is bad.
A lack of green spaces in large cities is a problem due to overbuilding and overuse of concrete. To solve this problem, new construction should be limited, and when a company wants to build a new building it should be forced to include some green spaces in their designs. When roads are constructed or repaired, a grass strip should be included in the design, and trees should be planted on either side of the road. Finally, a survey could be made of unused property in the city, and some of this property could be purchased and made into public parks.
Reading, Listening, and Acting
1 Before listening to a TV show called The Evos, read the following introduction and then discuss the questions in pairs.
1 Where do you think the meteors came from
2 Why do you think the friends fell asleep
Previously on The Evos: A breaking news report tells of seven meteors hitting each of the seven continents, as revealed by a scientist called Dr Evo. Meanwhile, three friends, Seb, Anie, and Laura are cycling through woods near their homes. After seeing a flash of light, they follow it. They discover a hole with a strange glowing rock inside. The news on Seb’s radio is talking about the meteors, so they realise this must be one of them. Seb says they should take a closer look. As he gets closer, he suddenly falls asleep, and as the others go to help him, they also fall asleep. They awake at dusk to the sounds of men searching for the meteor. They escape and agree to see each other at school the following day, as well as promising not to tell anyone. Some men, dressed in black protective suits, take the meteor away ….
I think the meteors came from a far galaxy and certain some sort of alien life.
Maybe the alien was hising in the meteor and it used something to make them alseep to prevent itself from being seen.
2 Now listen to the start of the new episode and match the abilities to the character.
Seb can move things with his/her mind
Laura can stop time
Arnie can move from one place to another
Dr Evo can make himself/herself disappear
3 Listen to the episode again and write down the words and phrases that have the following meanings and functions.
1 mentioning something they almost didn’t remember to say ___________________
2 wanting to talk about something different quickly ___________________
3 saying the same thing in a different way than before ___________________
4 talking about the most important point ___________________
5 adding another point to something already said ___________________
before I forget\I nearly forgot
just to change the subject for a moment
in other words
first of all\above all
furthermore
4 In groups, act out a scene from The Evos using the instructions below.
1 Discuss what happens next in the scene. Use the following questions to help you make a script. The scene only needs to be a few minutes long.
What happens to the characters after they meet Dr Evo
Do the men in black also have powers
How do the characters use their powers
2 Decide who will play each character. Choose a narrator to help the audience understand what is happening.
Dr Evo Seb Arnie Laura Narrator
Men in black suits Any other new characters you want to add
Laura: Where are we going, Dr Evo
Narrator: Dr Evo doesn’t respond. Laura looks at her friends. They look back at her, concerned. After a while, they arrive at the hidden location.
Dr Evo: Great. We have arrived. Please come into this room. All will be explained shortly.
Narrator: The friends go into the room. Suddenly, Dr Evo disappears, and the door slams shut behind them.
Arnie: Hey! What’s going on here
Seb: Let us out, man!
Dr Evo: Ha ha ha! You really thought I was a friend No! I want to use your powers. I can use your powers to take over the whole world!
Laura: But what about the men in black Aren’t they dangerous They're coming for us all!
Dr Evo: Oh no, no no. You have misunderstood. Actually, they work for me. They do not have any special powers, but they help carry out my experiments…..
Laura: Why you rotten little ...
Seb: (whispers) Laura! You can move things with your mind, right Can you try opening this door for us (whispers) I think so ... but it’s not going to be easy ...
Seb: (whispers) Don’t worry. We will buy you some time.
Narrator: So, while Laura uses her powers to open the door, Seb and Arnie distract Dr Evo. They get him to talk about himself—since that's what he loves to do the most! Finally, the door opens!
Seb: Arnie! Stop time now and get us out of here before more of his goons come! Right!
Narrator: Arnie stops time. If he is touching others, they will also stop time too, so all three can move at the same time. Using this power, they escape and run away. They now must go into hiding and make sure Dr Evo and his men in black team don't ever find him. Tune in next week for the next thrilling episode!
Reading and Writing
1 Look at the picture. What do you think is inside the cave Do some research about our planet to find the answers to the following questions.
How old is the earth
What is the structure of the earth
How deep is the earth’s crust
What is at the centre of the earth
What is the deepest cave ever found
I think the cave is probably empty, but it is really hard to tell without going in and exploring it.
The earth is thought to be 4.5 billion years old. It has five layers: crust, outer mantle, inner mantle, outer core, and inner core. The crust is 8 km to 70 km thick and made mostly from rocks. The mantle is both solid and fluid. At the very centre of the earth, there is the inner core, which is thought to be made up mostly of iron and nickel, and which is solid. The deepest cave on the earth is the Veryovkina Cave in the country of Georgia, which is at least 2,212 metres deep.
2 Read part of a story about an amazing journey to the centre of the earth by famous writer Jules Verne. Underline the words that describe the unusual environment the explorers discover. What natural environments does it remind you of
vast lake or even an ocean; shore was lined with shining sand; a huge rock wall that was being worn away by the endless action of the waves; lit up by a strange light; vast clouds; a tall dense forest, composed of trees formed like umbrellas; mushrooms in their thousands, and each at least thirty feet high.
The scene reminds me of a strange beach in the far north, where it is not cold enough to have ice or snow in the summer, but where there is very little life.
JOURNEY TO THE CENTRE OF THE EARTH
During the interview,
What questions would you like to ask them ？
1.At first I could hardly see anything. After so long descending deep into the earth through dark, narrow caves, my eyes were not used to the light. But when I could focus again, I stood amazed.
2."It's a...sea!"I cried.
3.“Yes, Axel,"my uncle replied,"and I shall give it my name,as it was discovered by me！"
4.A vast lake or even an ocean, spread far beyond where the eye could see. The shore(海岸)was lined with shining sand, and was being softly lapped by waves. It was covered with small shells(贝壳) which were once inhabited by the first living beings. Around this sea stood a huge rock wall that was being worn away by the endless action of the waves.
5.I could see far over this great sea because it was being lit up by a strange light. Not sunlight, of course, as we were deep below the surface. No; with its bright, clear whiteness, the light must have been electric. Under the "sky", if it could be called so, being made of rock, were also vast clouds. They were being illuminated by this light, but the light gave no heat, so the place felt rather gloomy. Here we were, shut up inside a cave of a size that could not be estimated. It must have been several miles high.
6.Human words cannot describe the discoveries of those who have been deep into the earth. My imagination was powerless before such wonders. I felt like I was on some distant planet, and was both amazed and rather scared. However, I was energised by the breezy salty air supplying more oxygen to my lungs. After many days in much narrower spaces, it was a great relief.
7."Ready to walk a little now "asked my uncle.
8."Yes, certainly."
9."Well, let us follow the shore then,"he said, and we began to explore.
10.Soon in front of us appeared a tall, dense forest, composed of trees formed like umbrellas. "Mushrooms!" said my uncle. And he was right! There were mushrooms in their thousands, and each at least thirty feet high.
11."Wonderful!"cried my uncle. "A botanist never had such a feast as this! Now look under your feet."
12."Oh yes!" I exclaimed.
13.I hadn't noticed the many bones, which were being crushed under our feet as we walked. Suddenly I thought, if once these monsters lived here, might some still roam through these gloomy forests I anxiously surveyed the landscape, but we were the only living creatures in this subterranean world. Thankfully!
14.Eventually we returned to the cave we had entered from, and I fell asleep with strange thoughts. Where did this underground sea end Where did it lead to
How did they get to the center of the earth

Giant Underground Ocean Found!
Today, explorers Peter David and his uncle Steven Winston announced that they had discovered a huge underground ocean while they were exploring a cave in the country of Georgia. David and Winston were on an expedition to find the bottom of the cave. It took them three weeks to pass the previous lowest point in the cave, which is 2,197 metres below the entrance. The two climbers then found a small side passage which they had to crawl through on their stomachs. After more than 200 metres, this passage opened up to a large room that contained a vast ocean of salt water. High above them was a light which must have been electric in nature. Along the shore were tall trees which looked like umbrellas. These were actually mushrooms. As they walked along the beach, they found many bones. However, they could see no living animals. After exploring the shores of the ocean for some time, they had to return to the surface as their supplies were running low. When asked how old the ocean was, Winston replied that it looked nearly as old as the earth itself, which is 4.5 billion years in age. Winston then went on to say that they intended to go back to the cave next year with more supplies and some small boats. “We are far from done with exploring this cave,” Winston said. “The earth’s crust is anywhere from 5 to 70 kilometres deep, but we’ve only gone down two kilometres. There is much more left to discover down there.”

SCIENCE FICTION OR SCIENCE FACT
Science fiction is one of the most popular genres of film. Showing us everything from alien worlds to intelligent robots and time travel, sci-fi films are extraordinary. But how much of this science fiction is also scientific fact Many sci-fi films are based on fiction: novels, short stories, or comics, which first came from someone’s imagination and were often influenced by earlier sci-fi works. However, some films try to make the science they show as realistic and accurate as possible.
The film Interstellar was a box-office success and was praised for how space travel and other scientific aspects of the plot were represented. The story takes place in the near future when living conditions on Earth threaten the survival of humanity. A brave team of astronauts and scientists begin a dangerous mission to find a new planet for humans to live on. Director Christopher Nolan wanted the film to be as realistic as possible. “Why simply imagine things that might happen in space or on an interstellar journey Why not actually look at the real science there ” he said. To make sure as much of the film as possible was grounded in real science, Nolan and his team were helped from the start by physicist Kip Thorne, an expert on Albert Einstein’s theories. Thorne provided the correct mathematics for the special effects team to generate the fantastic computer simulations that are seen in the film.
科幻小说还是科学事实
科幻小说是最流行的电影类型之一。向我们展示了从外星世界到智能机器人和时间旅行的一切，科幻电影是非凡的。但这些科幻小说有多少也是科学事实呢？许多科幻电影都是根据小说改编的: 小说、短篇小说或漫画，它们最初来自于某人的想象，往往受到早期科幻作品的影响。然而，一些电影试图使他们展示的科学尽可能真实和准确。
电影《星际穿越》在票房上获得了成功，并因为太空旅行和其他科学方面的情节表现而受到赞扬。故事发生在不久的将来，地球上的生活条件威胁着人类的生存。由宇航员和科学家组成的勇敢团队开始了一项危险的任务，即寻找一个新的星球供人类居住。导演克里斯托弗·诺兰希望电影尽可能写实。“为什么只是简单地想象可能在太空或星际旅行中发生的事情呢？为什么不看看真正的科学呢 ”他说。为了确保影片尽可能多地基于真实的科学，诺兰和他的团队从一开始就得到了物理学家基普 · 索恩的帮助，他是阿尔伯特 · 爱因斯坦理论方面的专家。索恩为特效团队提供了正确的数学方法，以生成电影中出现的奇妙的计算机模拟。
In the real world, the search for other habitable planets has been underway for many years. Space telescopes can identify planets orbiting stars by small changes in the stars’ light as the planets pass by. These searches have discovered countless planets. The next challenge is to find one that is neither too hot nor too cold, where there is water necessary for life forms to develop. Then the oroblem is how we would get there. As these stars and planets are many light years away, it would take hundreds or thousands of years to reach them. Creating a spaceship that could travel at the speed of light would be one option, but in the film, Earth does not have that much time and a quicker route must be found. Thus the problem to be overcome is time itself.
Again, real science provided an answer, which was then brought to the screen in the film. As Einstein famously described, time and space are not two separate things, but exist like a fabric that our universe is made of, called “space-time”. Objects such as planets and stars bend this fabric, creating the force we know as gravity. When this force is very large, space-time is bent a great deal, making it possible for a short cut, known as a “wormhole”, to appear. This would allow one to pass from one point in the universe to another without having to cross the space in between, therefore making the journey much quicker. Wormholes are often used in sci-fi stories, appearing as simple holes to pass through, but what would one actually look like Science tells us it would actually look like a sphere, through which we could see through to the other side, and so this is how it appears in the film.
在现实世界中，寻找其他可居住行星的工作已经进行了很多年。太空望远镜可以通过行星经过时恒星光线的微小变化来识别围绕恒星运行的行星。这些搜索已经发现了无数的行星。下一个挑战是找到一个既不太热也不太冷的地方，那里有生命形式发展所必需的水。那么问题是我们如何到达那里。由于这些恒星和行星距离我们很多光年，我们需要数百或数千年的时间才能到达它们。创造一艘可以以光速飞行的宇宙飞船是一种选择，但在电影中，地球没有那么多的时间，必须找到一条更快的路线。因此，需要克服的问题是时间本身。
再一次，真正的科学提供了一个答案，这个答案随后在电影中被搬上银幕。正如爱因斯坦著名的描述，时间和空间并不是两个独立的东西，而是像我们的宇宙构成的一个结构一样存在，被称为“时空”。诸如行星和恒星之类的物体弯曲了这种结构，产生了我们所知的引力。当这种力量非常大时，时空会发生很大的弯曲，使得一条被称为“虫洞”的捷径出现成为可能。这将允许一个人从宇宙的一个点到另一个点，而不必穿越中间的空间，因此使旅程更快。虫洞在科幻小说中经常被使用，看起来像是简单的穿越孔，但实际上虫洞是什么样子的呢？科学告诉我们它实际上看起来像一个球体，通过它我们可以看到另一边，这就是它在电影中的样子。
In the film, such a “wormhole” mysteriously appears near Saturn. Several astronauts have already been through, with some reporting back on promising planets they have found. The team travels through it to another galaxy in the hope of finding a new home. However, as hours pass on these distant planets, many years pass on Earth. This is also a realistic depiction of what such interstellar travel would be like, as described by Einstein’s theory of relativity. Time moves differently depending on where you are and whether you are still or moving.
Of course, sometimes real science has to be ignored to make sure that a film, which is only a few hours long, is entertaining and that viewers understand what they see. We cannot know exactly what interstellar travel looks like, but science can give us a good idea. Often, there is a fine line between science fiction and fact, which is always changing as science and technology progress. Things that were only being dreamed of years ago are now part of our everyday lives, such as the Internet, mobile phones, and soon even space travel itself. This is what continues to make sci-fi so exciting and popular, inspiring generation after generation to imagine our future existence.
在影片中，这样一个“虫洞”神秘地出现在土星附近。一些宇航员已经通过，一些报告回到他们已经发现的有希望的行星。研究小组穿越它到达另一个星系希望能找到一个新家。然而，随着时间在这些遥远的行星上流逝，在地球上也流逝了许多年。正如爱因斯坦的恆星际旅行相对论所描述的那样，这也是对这种情况的现实描述。时间的流逝取决于你所在的位置以及你是静止的还是移动的。当然，有时候真正的科学必须被忽略，以确保一部只有几个小时长的电影是娱乐性的，并且观众理解他们所看到的。我们不能确切地知道恒星际旅行是什么样子，但科学可以给我们一个好主意。通常，科幻小说和事实之间有一条细微的界限，这条界限随着科学技术的进步而不断变化。多年前我们只能梦想的东西现在已经成为我们日常生活的一部分，比如互联网、手机，很快甚至太空旅行本身。这就是为什么科幻小说如此令人兴奋，如此受欢迎，激励着一代又一代人去想象我们未来的生活。
