In the movie The Day After Tomorrow, global warming causes a second Ice Age. The movie has led to a lot of discussion: Could another Ice Age really be possible
On the first day when the movie was put on, environmental activist group MoveOn. org handed out thousands of leaflets outside theaters. Their message was, “Global warming isn’t just a movie. It’s your future. ” It is now widely accepted that the Earth is getting hotter.
One reason for this is the large amount of carbon dioxide in the air, caused by burning coal and petroleum（石油）. In Alaska, temperatures have risen by as much as 4.4℃ over the last 30 years, causing glaciers to melt（冰川融化）, and the sea level to rise. Some scientists say that the tide（潮汐） moves an average of three meters closer to the land each year.
This is seen in the Alaskan island village of Shishmaref, where houses are disappearing into the ocean. Soon, the village will be completely under water, and the people living there are already leaving to go to the mainland. However, most scientists believe that climate change could never happen as suddenly as the movie suggests, and that there is a danger that it might cause people to think that global warming is just the movie. But the movie’s director, Richard Emmerich, welcomes the discussion, saying that he wanted to make the movie show that global warming is not just science fiction, but a reality.
7．What is the topic of this text
A．Glaciers melting. B．Ice age. C．Global warming. D．Weather.
8．Why has the movie led to a lot of discussion
A．Because it shows global warming causes a second Ice Age.
B．Because the global warming causes the sea level to rise.
C．Because a lot of coal is burned to produce carbon dioxide.
D．Because the tide moves about three meters closer to the land.
9．What does the underlined word “leaflets” in Paragraph 2 mean in Chinese
A．海报 B．树叶 C．电影票 D．传单
10．What can we infer from the last sentence in Paragraph 3
A．A second Ice Age will come. B．The petroleum will become less.
C．The villages will be under water. D．The villagers will think about the topic.
11．Most scientists are worried that ________
A．climate change will happen suddenly. B．people might not take the situation as a reality.
C．the movie director welcomes the discussion. D．people living on islands are leaving for mainland.
The Plastiki looks similar to many other boats. However, if you get near to it, you’ll see there’s a big difference. It’s made of about 12,000 recycled plastic bottles.
One day, David De Rothschild was reading some information about the plastic in the sea. He found plastic brought serious problems to the sea. Soon, David De Rothschild decided to do something. To let everyone know the problem, he started building a boat made of plastic bottles.
When he was building the boat with recycled plastic bottles, he made sure the boat was easy to live on and use. The crew（全体船员）could grow vegetables on the back of the boat. They could also take a break from work and get some exercise by using the special exercise bicycle.
After everything was ready, David De Rothschild and his crew sailed the Plastiki across the Pacific Ocean from San Francisco, the USA to Sydney, Australia. It was never easy. David De Rothschild and his crew had to take care when heavy rains or strong winds came. It took them one hundred and twenty-nine days to get to Australia. David De Rothschild thought the boat could only travel once but it survived so well that he was planning to sail it again one day.
12．What could the crew do on the boat
A．Grow vegetables. B．Recycle plastic bottles.
C．Go swimming. D．Clean the sea.
13．How long did it take David De Rothschild to finish the sailing
A．About 1 month. B．About 2 months.
C．About 3 months. D．About 4 months.
14．What does the underlined word “survived” mean in Chinese

20．We probably find the passage ________.
A．on a notice board B．in a magazine C．in a storybook D．in a newspaper
It’s very important for us to learn about protecting the environment around us. Here is a 4R rule for us:
Recycle. Bottles, waste paper, glasses, plastic and so on can easily be recycled. By doing so, we can save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted（融化）and the melted things are made for new coke cans.
Reduce. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. We should use both sides of paper. Reduce boxes and cups which can be used only once. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary for us to reduce the waste.
Reuse. We should always think of reusing the usable things before throwing them out. Give our clothes we do not use or the ones which are too small to the poor. With a family, we may pass on such clothes to younger brothers or sisters.
Repair（修理）. If one of the legs of our table is broken, we can repair it instead of throwing it away. If we want to change for better ones, it is better for us to sell the old things or give them to other people who can use them after doing some repairing.
The more we do, the better environment will be.
21．Which of the following do you think can be recycled
A．Bottles. B．Coke cans. C．Glasses and plastic. D．All above.
22．The “Reduce” rule mainly requires us ________.
A．to reduce the waste B．to use boxes and cups only once
C．to cut down trees D．to use a little paper carelessly
23．Which of the following belongs to（属于）reusing rule
A．Collect coke cans or waste paper.
B．Shut off the electricity when leaving the room.
C．Give your old books to poor children.
D．Cut down trees to make chopsticks.
24．Which is the best way to deal with a three-legged desk
A．To repair it. B．To put it away. C．To throw it away. D．To pick it up.
25．What’s the main idea of this passage
A．The ways to recycle energy. B．The rules to protect the environment.
C．The ways to reuse school things. D．The rules to reduce pollution.
How green are you Do you know how to be green Here are some ideas for you.
Reduce means “useless”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It s better to use a china (瓷制的) cup and a lunch box because you can use them again.
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programs. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
So please remember these three words: reduce, reuse and recycle.

Recently, researchers have reported on a different way to break down different kinds of plastic. It could lead to easier, high-quality recycling, and help deal with plastic pollution. The world is full of plastic, but only 9% of plastic products are ever recycled. Every year, over 17 trillion pounds of plastic are washed into the oceans.
But bacteria may help recycle, even when humans don’t. Bacteria are tiny living things-so small that you need a microscope (显微镜) to see them. Some bacteria can “eat” other things by changing the chemicals in those things into something that will help the bacteria grow.
Researchers at a French company have discovered a bacterial enzyme (酶) that can break down plastic. The enzyme, which was first found in compost (堆肥) leaves, turns plastic into chemical “building blocks” that can then be used to create new products. The enzyme can especially break down PET, a type of plastic that is most commonly used to produce plastic bottles. It is the fifth most common type of plastic that we use.
The new enzyme was uncovered in research that was published last month in the journal Nature. Researchers studied over 100,000 microorganisms (微生物) to find one that could break down plastic quickly. The leaf compost enzyme was first discovered in 2012. Scientists changed its genes, allowing it to break down 90% of one ton of plastic in less than 10 hours.
“It had been completely forgotten, but it turned out to be the best.” said Professor Alain Marty, chief science officer at Carbios.
30．What do we know about the enzyme
A．It can break down plastic quickly.
B．It is a type of bacteria.
C．It can improve the growth of plants.
D．It is the fifth most common type of bacteria.
31．What does the underlined word “bacteria” mean in Chinese
A．垃圾 B．昆虫 C．细菌 D．塑料
32．What is Paragraph 4 mainly about
A．When the scientists found the new enzyme.
B．How the scientists found the new enzyme.
C．How the scientists changed the enzyme’s genes.
D．Where the scientists found the new enzyme.
33．What did Alain Marty mean in the last paragraph
A．Better late than never.
B．The new enzyme was forgotten by experts.
C．They forgot to change the enzyme’s genes.
D．It was too late to find the new enzyme.
34．What CAN’T you know from the passage
A．Most of the plastic are ever recycled.
B．We can’t see the bacteria without a microscope.
C．The enzyme was first found in compost leaves.
D．PET is a type plastic that is commonly used to build plastic bottles.
Think about what you like to wear on the weekend. There’s a good chance that you like to put on a pair of blue jeans. At any moment, about half of the world’s population is wearing jeans. But according to a new study, our love for jeans may be bad for Earth. Denim (牛仔布) might be putting some sea animals in danger.
Every time we wash our jeans, tiny bits of denim will flow out of our washing machines, down into the world’s rivers, lakes and oceans.
You might wonder: Isn’t denim made of cotton, a natural material How can it become a danger to nature Well, in the process of making jeans, denim is treated with many types of man-made chemicals (化学品). Some improve its durability (耐用性) and feel, others give jeans their blue color.
Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada. They found denim waste in all of the samples (样本) they had collected. It is feared that the harmful chemicals in denim have spread far and wide. Scientists aren’t yet sure how these chemicals might harm animals.
In the study, the scientists also washed jeans to see how many bits of denim each pair would drop per wash. The answer was frightening: About 50,000. Not all of them make their way into the environment. Wastewater treatment factories hold back 83 to 99 percent of them. This may sound pretty good. However, one percent of 50,000 bits are still 500 per wash. Now think about the number of jeans around the world and the times each of them gets washed. As a result, a large amount of denim waste still gets into the environment.
Does this mean we shouldn’t wear jeans Probably not “We need to buy fewer jeans and only wash them when we truly need to do it,” says Sam Athey, one of the scientists. “You don’t need to wash your jeans after having worn them only a couple of times.”
35．What influence might denim have on sea animals
A．It might do harm to some sea animals. B．It has no influence on sea animals.
C．It is good to all the sea animals. D．It can protect sea animals from danger.
36．Why do people add man-made chemicals when making jeans
①To save the materials and make more money.
②To improve denim’s durability and feel.
③To make jeans blue.
④To harm animals.
A．①② B．①③ C．②③ D．②④
37．How many bits of denim might get into the environment every year
A．Five hundred. B．Five thousand.
C．Fifty thousand. D．Too many to count.
38．What should we do according to Sam Athey’s words
A．We are not supposed to wear jeans.
B．We should buy fewer jeans and wash them fewer times.
C．We mustn’t wash our jeans.
D．We need to wash our jeans every day.
On a boat near Costa Rica, a team of marine biologists is helping a turtle. The animal is having trouble breathing, and the team discovers why—there is something inside its nose. A scientist tries to extract the object, but the turtle cries in pain. Finally, after another eight minutes, a long object turns up and is seen clearly: it is a 10-centimeter plastic straw.
The video of the turtle’s rescue has been viewed millions of times on YouTube. It has helped raise awareness of a growing problem: The world’s seas are full of plastic. Since 2000, there has been a huge increase in worldwide plastic production, but we recycle less than one-fifth of it. A lot of this plastic waste ends up in the ocean. Today, scientists think about 8.1 billion kilograms goes into the sea every year from coastal regions. Most of this plastic will never biodegrade, or they will take hundreds of years to biodegrade, which can be harmful to the environment.
This ocean plastic hurts millions of sea animals every year. Some fish eat plastic because it is covered with sea plants, and it looks and smells like food. Typically, eating plastic leads to constant hunger. “Imagine you ate lunch and then just felt weak…and hungry all day.” says marine biologist Matthew Savoca. “That would be very confusing.” In some cases, eating sharp pieces of plastic can seriously hurt sea animals and even result in death.
Plastic is useful to people because it is strong and lasts a long time—but this is bad news for sea creatures who eat or get stuck in it. In light of Savoca, “Single-use plastics are the worst.” These are items that are used only once before we throw them away. Some common examples include straws, water bottles, and plastic bags. About 700 sea species (including the turtle from the video) have been caught in or have eaten this kind of plastic. Luckily, the turtle survived and was released back into the ocean.
How will plastic affect sea animals in the long term “I think we’ll know the answers in 5 to 10 years’ time,” says Debra Lee Magadini from Columbia University. But by then, another 25 million tons of plastic will already be in the ocean.
39．The underlined word “extract” means ________.
A．ask for B．cut off C．pick up D．pull out
40．The second paragraph is mainly about ________.
A．how many people have watched the rescue B．how long people have used plastic products
C．how much plastic waste is thrown into the sea D．how serious the plastic pollution is in the ocean
41．What can we infer from the passage
A．The ocean plastic has the same taste as a sea plant.
B．People living on the coast prefer to use single-use plastics.
C．After eating plastic, sea animals would like to eat more food.
D．Scientists know clearly about the influence of plastic pollution.
42．What could be the best title for this reading
A．Dangers Facing Sea Turtles B．The Work of Marine Biologists
C．The Problem of Plastic Production D．How Plastic Harms Sea Animals
As we all know, environmental pollution is still serious nowadays. Our group wanted to know how many students knew about each kind of the pollution and we wanted to learn how often they sorted rubbish. So we did a survey among the students in our school. Here are the results of our questionnaire (问卷).
43．The survey is mainly about .
A．scientific research B．environmental protection C．everyday habits
44． is known by the fewest students.
A．Air pollution B．Water pollution C．Noise pollution
45．What can we learn from the results of the questionnaire
A．Air pollution is noticed by a large number of students.
B．The students don’t realize the situation of the environment at all.
C．Most students take enough action to sort rubbish.
When the air is polluted, we wear masks (口罩) to protect ourselves. What about bees and butterflies They can’t wear masks.
New Scientist magazine recently reported findings from James Ryalls and his team at the University of Reading, UK. Their study found that air pollution is harmful to pollinators (传花粉者) — insects like bees and butterflies. They can’t smell flowers because of the pollution.
Pollinators are important. They spread pollen (花粉) among plants with flowers. This helps the flower produce seed and fruit. Without pollinators, farms cannot make food. We all need pollinators.
To do their study, Ryalls’ team built eight areas. Then, they put nitrogen oxide and ozone (氧化氮和臭氧) into six of these areas. The other two areas had normal air. They were the control group.
“The results were much more severe than we thought,” said Ryalls. In their tests, the levels of pollution in the six areas were similar to “road traffic pollution”. In such conditions, 70 percent fewer insects entered the areas. Once they were there, they didn’t hang around. Visits to flowers dropped by 90 percent.
Scientists explained that gases like nitrogen oxide and ozone can break down the smell of flowers. This makes it hard for insects to find their food.
Maybe the most frightening thing is that the researchers created pollution levels that could be allowed in the UK. But Shannon Olsson, a scientist in India, thought the results were important because the study showed the level of pollution can keep pollinators away.
“Air pollution is another stress on insects.” said Ball. “That adds to all the other stresses… causing their numbers to decline (减少).”

No doubt that teens should also care about the world that we live in. Martinez is one of the most active environmentalist among the young people. When most teens are busy with sports, friends, and online games, he is working to save the planet.
So how does a teenager become a well-known environmental activist (活跃分子)
“I grew up in family where people were always thinking about the environment,” says Martinez.
When Martinez was just 6 years old, he decided he had to do something about climate (气候) change — a serious environmental problem. Scientists have been studying climate change for many years. They know that Earth’s climate changes on its own over time. But right now, it is changing more and more quickly than usual because of pollution created by people — by the cars, trucks and planes we ride in, and by the coal and oil we burn for electricity.
Martinez points out that climate change is a serious problem. “People can feel very helpless about climate change, like there is nothing they can do,” he says. But that is not true. “Humans caused climate change.” Martinez says. “And we can try to solve it.”
Martinez began looking for solutions (解决办法) when he was just a little kid. His elder brothers and sisters ran an environmental group called Earth Guardians, which was started by their mom. First, he listened when they had meetings. Soon, he was traveling around the country and the world. His goal To educate and raise people up to face the “war” of climate change.
Today, Martinez runs Earth Guardians. The group works with thousands of kids around the world. He speaks to students in classrooms about steps they can take to help the planet. And he writes and performs hip-hop songs about the environment. Martinez believes that if many people change their habits, the climate change can be cut down.
51．According to the passage, Martinez is influenced a lot by ________.
A．the online games B．his favorite sports
C．his family D．the scientists
52．In paragraph 3, the underlined word “that” refers to ________.
A．the change of climate
B．the pollution created by people
C．the climate change caused by people
D．the idea that people can do nothing about climate change
53．Martinez traveled around the world to ________.
A．look for a better place to live in
B．learn more knowledge about climate change
C．encourage people to fight against climate change
D．make friends with young people around the world
54．What’s the best title for the passage
A．Changes Of A Group
B．A Young Climate Leader
C．The Climate Change
D．Environmental Problems
E-waste is fast becoming a serious problem around the world. This report will examine this problem and provide some possible ways to solve it.
We live in a society that is producing and using electronics all the time. It is often cheaper to buy new products than to repair old ones. Also, through clever advertising, companies always encourage people to change their old TVs, mobile phones and computers for the latest modles. E-waste is created when we throw away old ones. In the EU alone, about 8,700,000 tons of e-waste is produced each year. Sadly, just over1,000,000 tons is recycled.
Burying (填埋) e-waste or burning it cause serious problems for the environment. Electronics have dangerous things in them. These things can then get into the ground or pollute the air when they are burnt.
In recent years, many countries have started recycling e﹣waste. However, their plans are not always managed properly. Sometimes electronics are just sent to poor countries such as Ghana. There they are often burnt in public areas, which is very bad for people’s health. Setting up recycling centers is a good way to solve this problem. E-waste recycling centers could recycle the parts that can be reused and deal with the rest properly.
Another way is to make producers responsible for their used products. This means that producers must take back old products which are no longer wanted. They should then make sure they are properly recycled or reused.
As for us, we should try to cut down on e-waste. Change electronics only when we have to. And don’t buy a product just to have the latest model.
E-waste is a serious problem in the modern world. Both producers and users must take actions and try to keep it to the smallest amount.
55．About ________ tons of e-waste is not recycled every year in the EU alone.
A．8,700,000 B．1,000,000 C．7,700,000 D．7,000
56．Which of the following is NOT true according to the passage
A．Building more recycling centers can help reduce e-waste.
B．When we abandon an old phone, we produce e-waste.
C．We should try to avoid changing electronic appliances.
D．Recycling e-waste is always managed properly.
57．We may read this article from ________.
A．a science fiction
B．a science magazine
C．a story book
D．a school newspaper
People can reduce, reuse, or recycle waste instead of throwing it away. Matt and Sam decided to do an experiment. They wanted to see exactly how much waste the three R’s could save.
First, they collected the rubbish from six classrooms at their school. They divided the rubbish into three groups:
Things that were reusable, such as a pencil or a marker that had been thrown away
Things that could be recycled, such as cans, glass, or paper
Things that were truly waste
Then, Matt and Sam weighed each of the three groups. They learned that 84%of the total rubbish thrown away that day could be recycled or reused. They decided to do something about it.
Matt and Sam presented the idea of starting a recycling programme to the school leaders. Then they worked with the Student Council. They prepared brochures (手册) to send home to tell the students and their families about recycling. They stated in the brochure that recycling helps to keep our planet healthy. The school bought colored containers (容器) for each classroom. Each room received a blue container for paper and a green container for glass and cans. They also received a red container for real rubbish.
Within a short time, each classroom in the school was sorting recyclable materials from rubbish before it was thrown. Matt and Sam decided to weigh the rubbish one more time. They wanted to check the school’s progress. They collected the rubbish from the red containers from the same six classrooms as before. They sorted the rubbish into three groups again and weighed each group. This time, they were pleased to find that the red containers were filled with 90% waste that should be thrown away. Only 10% of recyclable materials had been thrown into the red containers. Matt and Sam were pleased with their school’s effort at reducing waste on our planet.
58．By doing an experiment, Mat and Sam wanted to find out ________.
A．what things could be reuse
B．what recyclable materials could be saved
C．how much waste the three R’s could save
D．how much waste their school produced a day
59．What did Matt and Sam do in the recycling programme ________
A．They made a speech on recycling.
B．They wrote a report to the school leaders.
C．They bought colored containers for each classroom.
D．They helped students and their families knew about recycling.
60．Which word can best describe Matt and Sam ________
A．Responsible. B．Friendly. C．Independent. D．Confident.

Kristen Tapping, a graduate from London South Bank University, has invented a bike wheel that she says can help clean pollution from the air. It’s called Rolloe.
The wheel uses fins to pull in air as it turns, It then uses filters (过滤器) to take in polluted air and give off clean air back into the environment. The wheel can filter more air if it goes faster, although it still works at low speeds.
Tapping said users would need to change the filter every week, or after about 250 kilometers, to make sure the wheel continues to work well. The wheel fits in the front of a standard bike and weighs about one kilogram.
Tapping said she was encouraged to create the wheel when she was biking around London. “In traffic, you always notice the pollution; the heat, the gases and the smell,” she said. She predicts that if 10 percent of cyclists (骑自行车的人) in London had a Rolloe on their bike, they could filter about 266,865 m of air a day, although this has yet to be tested.
A recent report shows that London’s health costs because of air pollution are the highest out of the 432 European cities. The World Health Organization (WHO) has also said that outdoor air pollution causes about 4.2 million deaths around the world each year.
Tapping wants to use the wheel on shared bike projects at first, with the aim of making the wheels available for all bikes to use. She says she would also like to create a wheel that would fit in the back of a bike, as well as making them available in different sizes.
66．What is Rolloe
A．A university. B．An invention. C．Air pollution.
67．Why should the user need to change the filter
A．To let the bike run faster. B．To help people lose weight. C．To make the wheel work well.
68．What is Kristen Tapping’s future plan
A．To clean about 266,865 m of air a day.
B．To travel around 432 European cities by bike.
C．To make the wheels available for all kinds of bikes.
69．What is the passage mainly about
A．A bike wheel created to clean the polluted air.
B．A project that encourages people to ride bikes.
C．A standard bike which weighs about one kilogram.
President Xi Jinping said “Lucid waters and lush mountains are invaluable assets(绿水青山就是金山银山)”.
With the efforts of China’s government and its people, the rate of forest coverage (森林覆盖率) in China has reached 22.96%, compared to 5.05% forty years ago, according to a recent report from the State Forestry and Grassland Administration(SFGA).
Over the past forty years, China planted billions of trees as part of its fight against expanding(延伸的) deserts, mostly in its north. Each year, people sow seedlings(播种) over an area nearly the size of Ireland, according to Nature.
In 1978, China began a nationwide tree-planting program known as the Three North Shelter belt Forest Program, also known as “the Great Green Wall”. It has helped to plant more than 66 billion trees across 13 provinces in the country’s north to act as windbreaks(防风林), according to China Daily.
Since 2018, SFGA has made more efforts to build a greener country. Its purpose is to grow at least 6.7 million hectares(公项) of forest every year in the next 15 years. Besides planting more trees, China has tried to bring back grasslands. It has also used strict forest protection methods and banned(禁止) all commercial logging(商业伐木) since last August.
The high-speed growth of forest cannot happen without public participation(参与). For example, Ant Forest, an Alipay mobile payment app, plants real trees for users who get “green energy” by taking part in low-carbon(低碳) activities. Since 2016, it has helped to plant about 122 million trees in China’s driest areas. China was praised as “one of the most successful countries worldwide in greening the desert” by United Nations Environment Program Executive Director Erik Solheim.
70．What was the rate of forest coverage forty years ago
A．5.05 percent B．17.91 percent C．22.96 percent D．28.01 percent
71．Over the past forty years, China has planted billions of trees to ________.

D．There will be no desert in northern China.
It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted (融化) and the melted things are made for new coke cans.
4. Recover
When you buy a box of apples, there may be a few rotten（腐烂的）apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repairs. It is true that North America is a “throw-away” society（社会）. But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
75．_______ can be recycled.
A．Only hard things B．Many things C．Few soft things D．All things
76．The “recover” rule mainly requires us _______.
A．to throw waste things away B．to cover waste things with earth
C．to get back the useful parts D．to throw the whole things away
77．We can infer（推断） that the writer of this passage may live in _______.
A．China B．Japan C．Australia D．America

Plants and animals are largely made of water. So are humans. They need to keep enough water inside them or they could die.
We get some of the water we need by eating food that has water in it. Drinks, such as milk and tea, are mostly water, too. A person needs water every day. If we go without water for three or four days, we will lose too much water from our bodies. In very hot weather, we could lose this water in just one day.
What does water do to help our bodies Water helps to take the nutrition(营养)from food to our bodies. It also helps to take the wastes away from different parts of our bodies.
In our homes, we also need water for many things. We need water for cooking, washing and flushing(冲水) the toilet. About three quarters of the water is used in bathroom and toilet. The rest is mainly used in the laundry(洗衣房) and kitchen.
____________. It may come from a lake or a river. It may come from the sea, from the rain and snow or from the underground. Water rises from rivers and seas to make clouds, and then falls again as rain and snow. The water you drink has been around millions of years. It just keeps being recycled.
Many people work hard to make sure we always have clean water in our homes. Water is very important for all living things, so we should use it carefully.
82．A person can get water that he needs by ________ .
A．taking wastes away B．losing water quickly
C．changing water slowly D．eating and drinking
