Are you a tea drinker If so, you’re not alone. Every day millions of cups of this popular drink are drunk around the world, and it has been that way for thousands of years.
Tea can be poured from pots or brewed(冲泡) in the cup using tea bags. And it’s this second way that is causing people to worry. Research last year found some expensive tea bags might be leaving billions of microscopic plastic particles(微塑料颗粒) in the cup. Scientists from Canada found that some tea bags dropped high levels of microplastic into water. However, the World Health Organization said such particles in drinking water did not appear to be dangerous.
Most tea bags are made of paper, with a little plastic used to seal(密封) them shut. This has also led to discussion about whether they can be recycled. Many tea bags are composted(制成堆肥) now. However, the gardener Mike Armitage told the BBC that the plastic in the soil could be washed into streams and rivers and finally out to the sea.
But there’s good news too. Onilever, the owner of the tea brand PG Tips, says their tea bags are made with a little plastic and that they are suitable for composting. And the brand Yorkshire Tea says their tea bags do have plastic, but they’re actively developing recyclable things to replace the plastic.

More than 1,000 different kinds of pieces of plastic, including 115 cups, 25 bags, four bottles and two pairs of shoes, have been found inside a dead whale in Indonesia, according to local officials.
When the whale was found on the island, it was already decomposing when animal doctors arrived. So they were unable to be sure if the plastic caused its death, said Lukas, the leader of the World Wildlife Fund in Indonesia. The plastic weighed about 6 kilograms, or 13 pounds, he said.
But pictures of the dead whale caused a warm discussion. The people in the country have started to realize that it is because of using too much plastic. So has the government. Indonesia, a nation of about 260 million people was the world’s second-biggest producer of plastic waste in 2015, behind only China.
If the whales eat too much plastic, they will have a wrong feeling. They think that they are full. And that will lead them to eat less food that provides all the good things they need, said Nicholas who is the leader of the Ocean Conservancy. Moreover, eating too much plastic can make them reduce their weight, their energy and their swimming speed. As a result, whales are easier to be hurt by the sharks and many other dangerous animals in the sea.
More than 800 kinds of animals in the sea are affected by about 8.8 million tons of plastic which is thrown away freely in the ocean each year. Plastic can also stop the animals moving freely and sometimes they will cause them to die because they have to be under the water for too long. Some plastic can make a small hole in their stomachs after they eat it.
6．What does the underlined word “decomposing” in Paragraph 2 mean
A．腐烂 B．吸收 C．凝固 D．飘散
7．Which country produced most plastic waste in 2015
A．India. B．China. C．Indonesia. D．America.
8．What happens to the whales after eating too much plastic
A．They will swim faster. B．They will be more energetic.
C．They will eat less healthy food. D．They will be bigger and stronger.
9．According to the passage, we can infer that ________.
A．eating too much plastic makes whales feel much hungrier
B．people in Indonesia paid no attention to the death of the whale
C．the animal doctors are sure plastic didn’t cause the whale to die
D．Indonesia government will take action to stop the sea pollution
If your family is like many in the United States, it’s easy to get a cold bottled water right out of the fridge, right
But all those plastic bottles pollute the environment. In fact, Americans buy more bottled water than any other nation in the world, adding 29 billion water bottles a year to the problem. In order to make all these bottles, factories use 17 million barrels (桶) of oil. That’s enough oil to keep a million cars going for twelve months.
So why don’t more people drink water straight from the kitchen tap (水龙头) Some people drink bottled water because they think it is cleaner than water out of the tap, but that’s not true. In the United States, local governments make sure water from the kitchen tap is clean and safe.
People love the convenience of bottled water. But maybe if they realize the problem it causes, they would try drinking from a glass at home or carrying water in a refillable steel bottle instead of plastic.
Plastic bottle recycling can help — instead of going out with the trash. Unluckily, for every six water bottles we use, only one makes it to the recycling bin. The rest are sent to landfills. Or, even worse, they end up as trash on the land and in rivers, lakes and the ocean. Plastic bottles take many hundreds of years to disintegrate (降解) .
Water is good for you, so keep drinking it. But think about how often you use water bottles, and see if you can make a change. Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours.
10．According to the passage, a car uses ________ barrels of oil in a year.
A．12 B．17 C．29 D．60
11．Why don’t more people drink water out of the tap
A．Because water from the kitchen lap isn’t safe.
B．Because they think bottled water is cleaner than water out of the tap.
C．Because drinking bottled water is cheaper.
D．Because they are always too busy to boil water.
12．The underlined word “refillable” in the passage probably means “________”.
A．可再生的 B．可回收的 C．一次性的 D．可再装的
13．Which of the following sentences is TRUE
A．Only 10% of the water bottles we use can be recycled.
B．More and more people realize steel bottles are better than plastic ones.
C．It’s difficult for us to disintegrate plastic bottles.
D．We will never be allowed to drink bottled water any more.
14．The writer encourages us ________.
A．to recycle plastic bottles and save the environment
B．never to drink bottled water at home or other places
C．to use less coil to keep a car going for twelve months
D．to throw plastic bottles as trash on the land and in rivers

A new study shows that 86% of the world’s rivers have been damaged by human activity. The study was made by researchers from France, to find the situations of over 2,500 rivers around the world. They did not look at rivers in the Arctic and Antarctica or in wastelands. The scientists looked into changes to rivers over the past 200 years. They discovered that many kinds of things in over half of the rivers had been seriously influenced by humans. The researchers said there were many reasons for this influence. A big reason is the introduction of new kinds of fish into rivers. Other reasons include pollution, overfishing and farming.
The researchers say the worst-hit rivers are in western Europe and North America. This is because these areas have large and rich towns and cities. The lead researcher said: “Rivers along which there are highly developed countries, like the Mississippi River, are the most strongly influenced.” The River Thames in London was one of the worst-hit rivers in the study. The least - influenced rivers are in Africa and Australia. The researcher said: “This is probably because of fewer factories in Africa and a smaller population around the rivers in Australia.” He added that rivers in many rich nations were in worrying condition compared with 200 years ago.
20．What does the underlined word “damaged” mean
A．改良 B．破坏 C．延长 D．变道
21．How many rivers have been seriously influenced by humans
A．Over 1250. B．About 2150. C．Less than 2500. D．More than 2500.
22．Why are the rivers in Africa influenced least
A．Because there are fewer factories.
B．Because the towns and cities are rich there.
C．Because there are some developed countries there.
D．Because the population around the rivers there is small.
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. 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 plants 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.”
23．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.
24．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.
A．①② B．①③ C．②③
25．How many bits of denim might get into the environment every year
A．Five hundred. B．Fifty thousand. C．Too many to count.
26．What should we do according to Sam Athey’s words
A．We are not supposed to wear jeans.
B．We need to wash our jeans every day.
C．We should buy fewer jeans and wash them fewer times.
Balloons are a symbol of celebration. People love to release colorful balloons for special events, such as festivals and ceremonies. Colorful balloons may look pretty, but they can bring about some serious problems.
After balloons are released, they can end up hundreds of kilometers away from where they were released, causing great harm to the environment and wildlife. It is well known that popular helium(氦) balloons can travel up to 800 km before the helium releases and balloons fall to earth. This means they can fly almost everywhere, including waterways, oceans, mountains and farmlands.
Well, in our daily life, there are two types of balloons in general use. Most of the balloons we use are latex(乳胶) balloons. In fact it will take them six months to four years to decompose(分解) and they can cause pollution before they do. The other one is Mylar balloons. They are a kind of plastic balloons which cannot be decomposed and can stay in the environment forever. Similar to plastic bags, the Mylar balloons break into smaller pieces in the sun. Besides the balloons themselves, the ribbons, which are used for tying balloons, are also made of plastic.
All of these materials, if littered, can add to the amount of plastic waste our environment. At the same time, it can result in the injury or death of animals. Balloons may break up into smaller pieces over time. Sea animals, such as whales, turtles and seabirds, often mistake them for food, and if eaten, those small pieces can make them hard to breathe and then cause them to die. Besides, they can also easily get themselves caught together tightly in balloon ribbons. Even worse, it has been found that some birds are collecting balloon pieces, thinking that they’re food, and even feeding them to their babies.
So, don’t release balloons any more so as to reduce the pollution and protect animals. Every small step we take can make the world better, healthier and cleaner.
27．Paragraph 2 mainly tells us that ________.
A．helium balloons can fly very far away B．releasing balloons can produce rubbish
C．balloons are very important in our daily life D．balloons can have a bad influence on a wide area
28．What’s the biggest difference between Mylar balloons and latex balloons
A．Mylar balloons can’t be decomposed over time.
B．Mylar balloons can be used for the second time.
C．Mylar balloons’ pieces won’t turn into plastic waste.
D．Mylar balloons’ pieces could cause the death of animals.
29．Which of the following best shows the structure of the passage
A． B． C． D．
30．What’s the best title for this passage
A．Create a new world B．Protect sea animals
C．No more balloon releases D．Different kinds of balloons
When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it was the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. “And now”, CNN says, “It’s the Arctic’s turn.”
German scientists have recently found microplastics in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1800 pieces of microplastics per liter of (每升) snow.
How is plastic pollution reaching the Arctic According to scientists, “It’s clear that most of the microplastics in the snow come from the air.” They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.
Are they bad for us Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What’s more, earlier studies have shown that microplastics may contribute to lung cancer risk.
Microplastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystems along the way. They start in our wastewater, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we’re eating the plastic as well.
31．We can learn from Paragraph 1 that________.
A．the Arctic is the last really clean place left on earth B．the Arctic is an icy land of pure white snow
C．the Arctic is a beautiful icy land with clean air D．the Arctic has been polluted by plastic rubbish
32．The underlined word “contribute” means “_______” in Chinese.
A．cause B．mention C．support D．land
33．Where do most of the microplastics in the snow come from
A．From water. B．From air. C．From wind. D．From food.
34．Which of the following NOT true
A．We may breathe microplastics in Arctic. B．Microplastics may cause lung cancer.
C．We don’t have to mind microplastics right now. D．Microplastics have hurt ecosystems.
35．How does the writer end this passage
A．By advising us to drink clean water. B．By asking people not to eat sea animals.
C．By telling the seriousness of plastic pollution. D．By showing the beauty of Arctic.
In most situations, light helps us see. But nowadays humans are using too much of it so that it is in fact a kind of pollution.
When it comes to looking at the night sky, too much light makes it difficult for us to watch some of life’s most wonderful sights: stars, planets and even galaxies.
According to scientific research, about 2500 stars can be seen by the human eye without using any special equipment（装备）. But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big cities, people cannot see the sky filled with stars like they did in their childhood.
Light pollution affects more than just our view of sky. Research shows that lots of nighttime light can harm wildlife, too. When birds fly to another place over cities, they sometimes get lost by the brightness and fly in circles until they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.
Too much light at night may even affect human health, but scientists are not sure of that. They are still learning more.
In order to prevent things from going worse, governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are truly needed. They also shine lights down at the ground instead of up into the sky and use lower brightness levels.
Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed（不受打扰）life, too.
36．Why does the writer think that too much light is a kind of pollution ________
A．Because there are fewer and fewer stars.
B．Because human health has been affected.
C．Because too much light is a waste of energy.
D．Because some of the wildlife can be harmed.
37．Which of the following is NOT mentioned（提到）in this passage ________
A．The problems that light pollution has caused.
B．The reason why humans use too much light.
C．The ways that light pollution can be reduced.
D．The reason why fewer stars can be seen than before.
38．Which of the following is true according to the passage ________
A．There are about 2,500 stars in the sky.
B．Humans want to do nothing to reduce light pollution.
C．Sea turtles always get lost and die from tiredness.
D．Something has been done to reduce light pollution.
39．Which is the best title for the passage ________
A．Light pollution.
B．Stars, planets and galaxies.
C．Nighttime light.
D．Scientific research.
It is reported that some developed countries have shipped broken parts of computers to China. Last month Hong Kong officers found 131,000 kilograms of broken computers, TVs and phones sent from Japan.
Things like these are called electronic waste, or e-waste. Dealing with them is not an easy job . Every time an old computer breaks down, it needs to be dealt with safely. However, at present, broken computer parts are usually buried. It may be hundreds of years before they are really gone on earth. Many places in China are polluted by e-waste. Guiyu in Guangdong Province is one of them. This town is named as “the e-waste capital of the world”. It has to deal with 1.5 million kilograms of e-waste each year. Many of the poisons in e-waste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu badly polluted.
Luckily, the Chinese government begins to take actions to change the situation. This year, China has passed a new environmental protection puter companies like Lenovo and Dell are asked to recycle their old computers. Hopefully, the problem with e-waste will be solved in the near future.
40．The e-waste found in Hong Kong last month was from________.
A．France B．Japan C．America D．Germany
41．The town of Guiyu in Guangdong Province ________.
A．is the electronic capital of the world B．has serious e-waste pollution
C．spends much money on e-waste D．has the most serious pollution in the world
42．This year, the Chinese government has ________.
A．closed some computer companies B．asked people to hand in their old computers
C．made a new environmental protection law D．buried a lot of old computers
43．The passage is mainly about ________.
A．the e-waste problem in China B．the cost of burning e-waste

Read the following play and try to act it out.
Mr. Li: Hello, everyone. Class begins. I will ask you a question: What’s the most serious problem in the world
Betty: I think it’s the environment pollution:
Mr. Li: Good answer, Betty. It’s connected with our correct answer. But it isn’t correct.
Cindy: Is it global（全球的）warming
Mr. Li: Right! It’s a serious problem.
Betty: But it is very cold in winter. I think it’s global cooling!
Mr Li. In fact, global warming means the weather is out of control. So it will sometimes be very cold.
Betty: What causes “global warming”
Cindy: I know. Now people drive too many cars and the waste gases（气体）from the car pollute the air. It causes global warming.
Mr Li: You’re right. Do you know what will happen with the global warming
Betty: Yes. The ice in South pole（南极）is going to melt（融化）and many places will be flooded（淹没）with water.
Mr Li: What should we do to stop “global warming”
Betty: We should plant trees.
Cindy: We should also avoid driving cars.
Denny: I will go to. school by bike every day.
Mr. Li: OK. We all know the importance of protecting the environment. Let’s do it. right now.
44．What does Mr. Li think of Betty’s answer at the beginning of the play
A．Funny but right B．Great but wrong. C．Useless and wrong. D．Meaningful and right.
45．Which of the following is the reason of “global warming”
A．People drive too many cars B．People eat too much food.
C．People ride too many bikes. D．People plant too many trees.
46．Which of the following is TRUE
A．There are five people in the play. B．The discussion may take place in the library.
C．Mr. Li is the teacher D．The ice in North Pole is going to melt.
Noise pollution is a serious problem in big cities. A study found that Guangzhou had the worst noise pollution, followed by Delhi in India and Cairo in Egypt. Beijing came sixth. To help track(跟踪) and control noise pollution, a noise map has been developed by the Shanghai Academy of Environmental Sciences. It allows people to “see” noise.
On the map, there are 12 colors which means 12 noise levels(标准). For example, purple means noise between 30 and 35 decibels(分贝) while dark green means noise between 40 and 45 decibels. The area where the noise is between 60 and 65 decibels is shown in bright red. Blue means noise between 75 and 80 decibels. Roads along busy elevated ways(高速公路) are often red or blue, while neighborhoods and parks are usually quieter, showing a color of green or purple.
In fact, years earlier, some countries in Europe have been required by the EU to make noise maps for cities with a population of over 250,000. Some cities in Japan, South Korea and the US also have noise maps. Most of these countries don’t update(更新) their maps often, but the noise map of Shanghai gets updated every 20 minutes, giving researchers an idea of how the noise level changes with time in certain areas. For example, noise levels may rise as a car comes near, and fall again after it has passed. Weather and season also make a difference to noise levels. The noise map will be used to help reduce(减少) noise in cities. It can also be helpful if you’re looking for a quiet neighborhood to live in.
47．According to the study, which city has the second worst noise pollution
A．GuangZhou. B．Delhi. C．Cairo.
48．Noise from roads along busy elevated ways often can reach ________ decibels.
A．30-35 B．40-45 C．75-80
49．According to the passage, what can change the noise levels
①weather ②sunlight ③time ④traffic
A．①③④ B．①②③ C．②③④
50．What can we learn about the noise map from the passage
A．It was first developed in Japan.
B．It has been widely used around the world.
C．There will be less noise pollution thanks to its using.
51．What’s the purpose of this passage
A．To introduce the noise map developed by Shanghai.
B．To ask people to pay attention to noise pollution.
C．To show how the noise map of Shanghai was created.
