Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don’t have to worry about polluting the air every time they take the bus.
A city in California has got some new buses. They cost $490,000 each. The new buses are different from the old ones. These new buses are better for the environment. They are called hybrid buses. They run on diesel (柴油的) and electric power. This will help keep the air cleaner.
The man drove the new bus on Wednesday and noticed a difference right away. “I get to have clean air for a change”, said driver Melvin Day. “I’m smelling diesel all day long when I drive the old ones.”
The company that builds the buses had many good things to say about them. For example, they said they use a lot less fuel (燃料). They also said that they are 90% cleaner for the environment. The buses are very quiet, too.
The buses have a diesel engine in the back and batteries (电池) on top. When the engine starts up, it is powered by electricity. Then the diesel power takes over.
Over time the city would like to use the new hybrid buses instead of all 50 of their buses. They hope to do this over the next three years. The city will give money to help buy the new kind of buses.
One other bit of good news: the price of the bus ticket will not rise because of the new buses.
1.Why are the new buses better for the environment?
A. Because they’re cheaper than the old ones.
B. Because they’re very quiet.
C. Because they run on diesel and electric power.
D. Because they are new.
2.The underlined word “hybrid” in Paragraph 2 means ______ in Chinese.
A. 混合动力的 B. 前卫的 C. 新颖的 D. 节约的
3.Which one is NOT true about the new buses?
A. The buses are very quiet.
B. They use a lot less fuel.
C. They will keep the air cleaner.
D. They can drive faster than the old ones.
4.How many buses does the city have now?
A. 50 B. 90 C. 45 D. 490

Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don’t have to worry about polluting the air every time they drive their cars. They no longer need to face the problem of not having enough fuel（燃料）either.
Although scientists have been trying for many years to develop a new kind of car that does not need gasoline (汽油), they have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity（电）. This is the famous “hybrid car”. This car gets its name from the fact that it has a gasoline engine (引擎) and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars.
Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.
1. The underlined word “they” in Paragraph (段落) 2 means ______.
A. cars B. drivers
C. engines D. scientists
2.Hybrid cars ______.
A. increase air pollution B. run only on electricity
C. have no engines inside D. need less fuel than ordinary cars
3. The passage tells us that with the development of cars, we may ______.
A. like electric cars B. drive cars easily
C. live in the world with clean air D. understand how hybrid cars work
4.The best title for the passage would be ______.
A. The Car of the Future B. The Meaning of Hybrid
C. The Use of Hybrid Cars D. The Invention of the Car

Air pollution is a big problem for cities. Many people are dying from it. But how can we tell the air quality(质量) is good or bad?
Joris Lam has invented a birdhouse that can tell us about the air quality. On a tree next to a canal (运河) in Amsterdam, a small birdhouse will shine bright green when the air is clean. If you are standing near the birdhouse, it will also give you a free Wi-Fi connection. So Joris’s birdhouse is called TreeWifi. It can be put on a tree around your house to test the air quality. People can see a screen with information about local air quality and how to improve it. TreeWifi is a simple way for people to know about the air pollution around them. If the birdhouse doesn't shine, people will care more about the environment. It tells them to change their lifestyles. For example, to protect the air, they can ride bikes instead of driving cars.
Joris and his team are trying to make some changes to the birdhouse. In the future, the heat of its green light will be used to keep birds warm in winter.
1、2题完成句子；3题简略回答问题；4题找出并写下第二段的主题句；5题将文中画线句子译成汉语。
1.Many people die because of the ______.
2.When the air is ______, the small birdhouse will shine bright green.

Going Green
Green is no longer just a color. It is a new way of thinking about the world and a way of living your life. It’s catching on all over the world. More and more people decide to “go green” because they know that we only have one planet to live on. We won’t be able to live on it much longer if we keep wasting energy, and destroying(破坏) our home with air, land, and water pollution.
“Green Living” means:
Understanding that your choices affect(影响) not just you, but everybody everywhere.
Understanding that your choices affect not just today, but the future.
Understanding that when we talk about “saving the planet” or “saving the environment,” we are actually talking about saving ourselves!
You may be thinking: “Hey, I’m just one person, on a planet with billions. I can’t really make a difference.” Well, have you ever seen a group of people do “the wave(波浪)”? It always starts off with one or two people, jumping up and down like crazy. Soon thousands of people are joining in. “Going green” is just like that. It starts with small, simple actions. It can soon build into a wave that will change the whole planet and lead us all to healthier, happier lives.
Many students have already shared with us their efforts to help the environment:
Gabrielle, 12, writes, “I have helped my community plant a garden and I ride my bike or skateboard to school.”
Kaitlyn, 10, says, “Lots of paper towels are thrown away, so I use a reusable cloth towel to dry my hands instead.”
“I always recycle(重复利用)” says Natalie, 13. “You can call me a recycler! I always look at the bottom of things. I want to see whether they have the little sign that tells you it can be recycled. So I almost recycle everything!”
Now it’s your turn to think about how you can “go green”. Make important choices and take actions to improve the environment right around you and the health of the whole world.
1.What does the expression “catch on” in Paragraph 1 probably mean?
A．Go worse.
B．Come to an end.
C．Get help.
D．Become popular.
2.From the passage we can learn that ______.
A．our choices can’t affect the future
B．one person can’t make a difference
C．our planet is destroyed by pollution
D．going green starts with small actions
3.The writer may agree that ______.
A．going green is hard for students
B．going green means changing others
C．going green is actually a choice
D．going green remains far away from us

Cars
Cars are getting bigger. Bigger cars burn more gas and increase(增加) problems with air pollution. So try to walk， ride， or take buses or subways. And if you drive a car， keep it in a good state. This can save gas and make less pollution.
Energy
The biggest use of energy is for heating and cooling. So turn up your air conditioner（空调） and turn down the heat（加热器）， especially at night. Use energy-saving lights. And remember to turn lights off.
Products（产品）
Each American family throws away about 10 kilograms of litter every day. Try to make less waste. Ask yourself before you buy something： Do I really need it? Buy products that you can reuse(重复使用).
Water
Showers use a lot of water. Take shorter showers or buy a special small shower head. This can cut water use in half.
