When gasoline 2 dropped and new technologies on gasoline cars were developed，electric cars were out of date. Gasoline cars became more popular 3 ，because they could go farther without stopping.
During the 20th century，gasoline cars got bigger，heavier and faster. They needed more fuel，and it 4 more air pollution. For years，the car makers didn't worry about pollution. They didn't worry about how much gasoline cars used，either. But when people began to 5 that there was not enough oil on the earth，they asked car makers to produce more efficient (高效能的) and less polluting cars.

五、阅读理解。
Wind power is a very clean source (资源) of energy. This is how wind power works. Wind makes windmills (风车) spin (旋转). When the windmills spin, they make electricity. Then we can use the electricity.
A lot of people think that wind power is new, but that's not true. For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity.
Wind power is a very popular source of energy. Most people think that we should use it more and more. First of all, it's clean. Windmills don't pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap, and it's getting even cheaper.
A lot of people don't understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example，some people say that windmills are dangerous for birds. The idea used to be true, but it isn't true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren't dangerous for birds.
However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn't blow all the time, so we can't use wind power all the time. Finally, windmills are noisy.
Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 25 percent of the world's power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.
1. When did people start using wind power
A．About 25 years ago. B．About 80 years ago.
C．About 500 years ago. D．Over 1，000 years ago.
2. Why is wind power a popular source of energy
a．Because it's clean.
b．Because it sounds believable.
c．Because it becomes more convenient.
d．Because we can use it for a long time.
e. Because it's getting cheaper and cheaper.
A．a，d，e B．b，c，d C．a，c，d D．c，d，e
3. Why DON'T new windmills kill birds
A．Because they spin slowly. B．Because birds don't fly near them.
C．Because new windmills don't spin. D. Because they are shorter than old windmills.
4. How many problems with windmills are mentioned in Paragraph 5
A．Five. B．Four. C．Three. D．Two.
5. What is the best title for the passage
A．Expensive Windmills B．Dangerous Birds
C．Popular and Clean Wind Power D．Common and Ugly Electricity

A company in San Francisco，California，has found a way to turn used plastic bottles into women's shoes. Every day，millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles are thrown in landfills or are burned with other waste products.

Rothy's shoes are sold online. They are flat shoes，with either a rounded or pointed toe. They come in different colors and designs. They cost either $125 or $145 per pair，depending on the design. After an American actress discovered them last year，the demand (需求) for the shoes grew.
Roth Martin，one of the bosses of the company，says that when the shoes wear out，customers can return them to a company that uses them as materials to make other products. For now，the shoes are only available to be shipped (上市) in a few countries. However，the company says it will add international shipping in the near future. Would you like to buy a pair of the environmentally friendly shoes

Dear friends，
In order to make the environment more beautiful，we should do what we can to protect it. First，we should plant more trees and flowers to make our city more beautiful. Also，always remember not to throw rubbish or pour waste water everywhere. As we all know，water is becoming less and less. So it's quite necessary to save water. For example，turn off the tap after washing. Last but not least，we'd better ride a bike or walk when going out instead of driving a car.
In my opinion，if everyone tries his or her best to protect the environment，our city will become nicer and cleaner!
Thank you!
Yours,
Wang Dong
