Read the passage and answer the questions.
In space, even the most straightforward, everyday tasks can be quite difficult for astronauts who are spending months on board a spacecraft. In this zero gravity world, there is no up or down, and while sleeping on the ceiling might sound like fun, astronauts need to be strapped to sleeping compartments to protect themselves from injury.
Although not many people enjoy doing housework, astronauts need to find the self-discipline to keep the small interior of their spacecraft clean; even using a vacuum cleaner to stop dust from getting into the air filters. A vacuum cleaner also comes in handy for fetching items that are floating around out-of-reach!
Astronauts also need to keep themselves clean. To do this, they use special soap and shampoo which do not need to be rinsed off with water. After brushing their teeth, they spit into a towel.
With no gravity to push against, astronauts’ bones and muscles can become weak. In order to stay fit, astronauts have to exercise on a regular basis.
And while some food items, such as cakes and fruit can be eaten in more or less the same way that they are on Earth, water needs to be added to much of the food that is eaten in space. Nonetheless, a menu for a hungry astronaut can still be varied and balanced, often including soup, prawn sandwiches, as well as fruit yoghurt. And as salt and pepper would simply float away, astronauts are provided with these in liquid form.
Carrying out these everyday tasks effectively helps the astronauts stay healthy and focus on their work in space — after all, imagine what would happen if they caught a cold and started to sneeze!
1 What is the main reason why everyday tasks are less simple in space
2 Why is it important for astronauts to exercise regularly
3 What else do you know about life on a spacecraft
Everyday tasks are less simple mainly because of the zero gravity in space.
It’s important for astronauts to exercise regularly because with no gravity to push against, astronauts’ bones and muscles can become weak in space. Exercising regularly can help them stay fit.

Sample:
Sunday 12 April
I was lucky enough to be chosen as a visitor to the space station! After an exciting blast into orbit, I couldn’t wait to look through the space station windows into deep space! You can imagine my disappointment when I didn’t see many stars. The astronauts laughed and explained to me that we were still in the sunlight, so of course we couldn’t see much, because the light was too bright.
Shortly after, we passed into Earth’s shadow, and I looked out of the window to see the most amazing number of stars! I felt very excited! This is the most unforgettable experience on the station. Soon after that, it was time for dinner. The thing I noticed most was not the zero gravity measures for eating, but the fact that the food didn’t have much taste. And my nose felt blocked. It turns out these things are related, because in zero gravity, your face swells up more. After that, it was time to get strapped into bed. It was a bit hard to sleep in zero gravity--my arms kept floating away, and I woke up to see them right in front of my face, instead of lying on the bed like they would on Earth. Despite even simple things being harder to do, I really enjoyed being in zero gravity, and I loved being able to float around instead of having to walk. It’s a pity my stay on the station was so short. It would have been great to stay longer and learn more about life in space!

Read the news report and find out what the Voyager 1 spacecraft took into space.
Voyager 1 is the spacecraft most distant from Earth. It contains a record called Sounds of Earth, which has recordings of greetings, music and sounds from Earth, as well as many photographs of our world. It is hoped that the record will be found by other civilisations on distant planets and help them learn about us.

Look at the title of the passage and predict what “eyes” refers to.
EYES UPON THE NIGHT
1 The night sky has been an endless source of fascination since the start of human history. For example, the mysterious large-eyed, bronze statues of the ancient Shu Kingdom, discovered at the Chinese archeological site at Sanxingdui, were believed to have been able to look across great distances into the stars. In reality, humans can see very little of the night sky with the naked eye. And, for a long while, people were unable to understand what they could see. Not knowing what the stars were, people in ancient times used their imaginations to create a world in the sky.
Now read the passage and check your prediction.
2 Our power to investigate and thus understand space changed dramatically when the first telescope was angled at the night sky, increasing as it did the power of the human eye and enabling us to understand that the universe is far larger than was previously imaginable. The planets were seen to be worlds similar to our own, many of them even having their own moons. Soon, it was understood that the Sun was just one star among billions in the galaxy we call the Milky Way. Some 300 years later, we learnt that the Milky Way itself was just one galaxy among billions of others, spread across the blackness of space like great islands of light and matter floating in a vast cosmic ocean.
3 Almost 400 years after the first Earth-based telescope was invented, the Hubble Space Telescope was launched into orbit, giving astronomers - indeed all of us - the first breathtakingly beautiful images of our universe taken from beyond Earth. Nothing in history has allowed us to see so much over such great distances, from enormous clouds of gas where stars are being born, to huge black holes, and even to new planets where we might conceivably find life. Not only that - it has also helped us to work out the age and nature of the universe, and discover the incredible fact that the universe is expanding at an ever-increasing speed.
4 To see even further into the universe, many countries are now engaged in building ever more advanced telescopes. Currently, China operates the world's largest and most powerful radio telescope, the FAST telescope, completed in 2016. The 500-metre dish of the "Eye of Heaven", as it is known, is being used in the search for dark matter, thought to be composed of subatomic particles invisible to ordinary telescopes. This vast dish also has the ability to explore regions of space billions of light years away, right at the edge of the visible universe.
5 The Hubble and the space telescopes constructed after it will allow us to see further and further into space. We will view stars and galaxies billions of light years away and look back at a past that was billions of years ago. Using ever-larger radio telescopes as our eyes, we will one day be able to look back to a time in the very early universe, before the existence of light. But the human quest for knowledge reaches even beyond that. So much of the universe remains unexplored that we are still close to the start of this incredible journey of discovery.
What does “eyes” refer to
The “eyes” not only refer to the mysterious large-eyed, bronze statues of the ancient Shu Kingdom, the Hubble Space Telescope and the FAST telescope, but also refer to the great human spirit of exploration.
Read the passage and divide it into parts, then summarise the main idea of each part.
Part 1 Paragraph 1
The way of understanding the night sky in ancient times.
Part 2 Paragraphs 2~4
The development of the telescope and the development of understanding the space.
Part 3 Paragraph 5
There will be a long and incredible journey of space exploration.
The order in which a series of ideas is conveyed in an essay is called “sequencing”. Time sequencing is a common method to explain how events change and develop with time. It is often used to discuss changes and developments.

4 Have you ever used a telescope or been to a planetarium Share your experience with the class.
3 The first passage is about the Challenger disaster. Although it was a tragedy, people did not stop exploring space. This shows that people will always seek to explore, even if some lose their lives in doing so. The second passage is about the development of the telescope, and how it reflects our desire to explore the unknown. Unlike the exploration conducted by astronauts such as those in the Challenger, the exploration in the second passage was conducted by people located on Earth, at no personal risk. Nonetheless, the knowledge gained from telescopes is immense. The passages show that there are different ways of exploring the universe and gaining knowledge.

The Call of the Challenger
1 Ever since Neil Armstrong first set foot on the Moon back on 20 July 1969, people have become accustomed to the notion of space travel. Millions watched that first lunar landing on black and white television sets, their hearts in their mouths, aware of how arduous and hazardous an undertaking it was, and of the many things that could go wrong. With Armstrong's now famous words "That's one small step for man, one giant leap for mankind", what had once been considered impossible had now been achieved. Guided by a computer that was much less powerful than the ones used by today's average school students, all three astronauts of the Apollo 11 mission made it safely back to Earth.
2 Following the Moon landings, space travel rapidly became unexceptional to the public, as innovations succeeded each other. By the early 1980s, the great rockets previously used in the American space programme had been replaced by the space shuttle. When the Challenger space shuttle took off on 28 January 1986, the world seemed to have lost its wonder at the amazing achievements of the astronauts involved. But this was going to be no ordinary excursion, and millions of people tuned in to witness the take-off on TV. It was special because Christa McAuliffe aged 37, an ordinary teacher and mother, was about to become the first civilian in space. She planned to give two 15-minute lessons from orbit: the first to demonstrate the controls of the spacecraft and explain how gravity worked, and the second to describe the objectives of the Challenger programme. Christa hoped to communicate a sense of excitement and rekindle interest in the space programme. With the eyes of students across the nation upon her, she might have inspired an entirely new generation of astronauts and space scientists.
3 Tragically, she never returned to her classroom as the shuttle exploded just over a minute after taking off in Florida, and all seven astronauts on board were killed. The world went into shock, most people having assumed that this space flight would be no more dangerous than travelling in an aeroplane. How wrong they had been! Instantaneously, excitement and optimism turned into terror and failure. It was the most disastrous space accident ever, and it cast a shadow on people's hearts.
4 "I can remember that day so clearly, watching the take-off on TV at school," said one student. "There was an ordinary teacher on the Challenger, and we were all very excited. We didn't have much patience waiting for the launch. We had seen the smiling faces of the astronauts waving to the world as they stepped into the shuttle. Then, little more than a minute after take-off, we saw a strange red and orange light in the sky, followed by a cloud of white smoke. The Challenger had exploded in mid-air and we all started screaming."
5 Following the shock of the Challenger disaster, space shuttle flights were suspended for nearly three years while the cause of the disaster was investigated, and some of the shuttle's components were redesigned. But there was never any doubt that manned flights would continue, and on 29 September 1988, the space shuttle programme resumed with the successful launch of Discovery.
6 It has now been over 30 years since the loss of Challenger and although the lives of its crew were cut tragically short, they take their place alongside the other heroes of space exploration, such as Gagarin, Tereshkova, Armstrong and Yang Liwei. The memory of those seven will live forever, written in the stars, inspiring us to join them in humanity's greatest journey of exploration and discovery. The sacrifice of the Challenger calls to us, reminding us that we must continue to reach for the stars, no matter how distant they might seem.

Part 1 Paragraphs 1~2

【语法讲解】
情态动词
情态动词本身有一定的词义,表示语气的单词。但是不能独立作谓语,只能和动词原形一起构成谓语。情态动词用在行为动词前,表示说话人对这一动作或状态的看法或主观设想。 情态动词虽然数量不多,但用途广泛,主要包括下列单词和短语:can (could)、may (might)、must、have to、will (would)、need、ought to、dare (dared)、shall (should)。
1. can, could
(1) 表示能力(体力、知识、技能)。
Can you skate 你会溜冰吗
此时可用be able to代替。can只有一般现在时和一般过去式;而be able to则有更多的时态。
I’ll not be able to come this afternoon. 今天下午我不能来了。
当表示“经过努力才得以做成功某事”时应用be able to,不能用can。
He was able to go to the party yesterday evening in spite of the heavy rain. 尽管下着大雨,他昨天晚上还是去参加了聚会。
(2) 表示请求和允许。
—Can I go now 我现在可以走了吗
—Yes, you can. / No, you can’t. 是的,可以/不,你不可以。
此时可与may互换。在疑问句中还可用could、might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
—Could I come to see you tomorrow 明天我能来见你吗
—Yes, you can. ( No, I’m afraid not.)可以。(我恐怕不能。)
(3) 表示客观可能性(客观原因形成的能力)。
This hall can hold 500 people at least. 这个大厅至少能容纳500人。
(4) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。
Can this be true 这能是真的吗
2. may, might
(1) 表示请求和允许。might比 may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。
—Might/May I smoke in this room 我能在这屋里抽烟吗
—No, you mustn’t. 不可以。
用May I... 征询对方许可时比较正式和客气,而用Can I... 在口语中更常见。
(2) 用于祈使句,表示祝愿。
May both the bride and groom have long and happy lives.
祝新郎新娘白头偕老,幸福美满。
(3) 表示推测、可能性(不用于疑问句)。might不是过去式,它所表示的可能性比may小。
He may/might be very busy now. 他现在可能很忙。
3. must, have to
(1) 表示必须、必要。
You must come in time. 你必须按时来。
在回答引出的问句时, 如果是否定的, 不能用mustn’t (禁止,不准),而用needn’t、don’t have to(不必).
—Must we hand in our exercise books today
我们必须今天交练习本吗
—Yes, you must.
—No, you don’t have to/you needn’t.
(2) must是说话人的主观看法, 而have to则强调客观需要。must只有一般现在时, have to 有更多的时态形式。
His play isn’t interesting, I really must go now.
他的比赛没意思, 我现在必须走了。
I had to work when I was your age.
当我是你这个年龄时我不得不工作。

Some birds will fly south when winter comes.

(4) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式,且没有“现已无此习惯”的含义。

Work in pairs. Read the passage and answer the questions.
The dramatic scientific developments of recent years have brought space exploration back to public attention. As getting into space is however, still not an easy task, more and more space camps and other places are providing simulated space adventures.The Space Camp, founded in 1982 under NASA, is an educational camp, where children can learn about space travel and astronomy, and even have the chance to have lunch with an astronaut! So far, the camp has inspired hundreds of thousands of young people from the US and from elsewhere around the world. What's more, some of its ex-students have even grown up to become astronauts!
