Since the first Earth Day started on April 22, 1970, people around the world have been encouraged to protect the environment and natural resources．Gaylord Nelson started this holiday．On the first Earth Day， 20 million people took part in Earth Day events．

Earth Day activities can include learning something about technology like cars that are more environmentally friendly and special houses that save energy and water．An organization called the Earth Day Network encourages people to use clean energy which doesn’t pollute the environment．Most of our energy comes from fossil fuels (化石燃料) that are found underground． Coal， oil and natural gas are examples of fossil fuels．Fossil fuels come from plants and animals that lived millions of years ago． Burning fossil fuels to create energy pollutes the air and water． Many scientists think that burning fossil fuels also increases the temperature of the earth． To reduce the use of fossil fuels． scientists are experimenting with hydrogen-powered (氢化发动的) cars． These cars don’t pollute the air like gas-powered cars．

Some scientists guess that by 2025, fossil fuels will run out．When people can no longer use gasoline， they may use fuel cells instead． Fuel cells use hydrogen to create energy． People do not need to worry about hydrogen running out， because it is renewable and replaceable．

In Washington， D.C.， a few people drive cars that run on fuel cells． When these cars need more energy, drivers can go to a hydrogen pump．The first hydrogen pump for the public opened in November 2004， marking an important step toward a cleaner environment．

1.what can we learn from the passage?

A．Fossil fuels don’t pollute the air．

B．Hydrogen-powered cars make less pollution．

C．Many drivers are driving hydrogen-powered cars．

D．We can find many hydrogen pumps in the USA．

2.How long may people still be able to use fossil fuels?

A．Twenty years． B．Over thirty-eight years．

C．More than ten years． D．About seventeen years．

3.Which of the following is not mentioned?

A．Scientists are producing more hydrogen-powered cars．

B．Some people drive fuel-cell cars in Washington．

C．Fossil fuels come from plants and animals．

D．We can learn about environmentally friendly technology from Earth Day activities．

4.When do fossil fuels pollute the air?

A．When we use them to create gasoline．

B．When people get them from the underground．

C．After being burned to get energy．

D．After getting them from a hydrogen pump．

5.Because hydrogen is renewable， we don’t need to worry that ________．

A．it will be used up B．it can be used for creating energy

C．it will pollute the environment D．it will be cleaner

Beijing—No Car Day was first started by 34 cities in France on September 22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.
The first No Car Day in China was in Chengdu in 2001. Other cities, including Beijing, Taipei, Shanghai and Wuhan also support the day.
In Beijing, more and more people are joining in the activity. It asks drivers to leave their cars for one day each week and walk, take a bus or subway or ride a bike to work. The slogan（口号）for the activity is,“If we drive for one less day, we can have one more nice day.” Beijing is trying to have 238 blue sky days this year. In the first quarter of this year Beijing only have 52 blue sky days. This was 11 days less than the number for the same period last year. Car exhaust(汽车尾气) is one of the most important reasons of the pollution. We must do more for No Car Day.
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive.” said Wu Zonghua, a car club chairman.
【小题1】There are_______ cities in China that support No Car Day according to the passage.

　　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(明智的). A large number 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. In a family, you may pass on such clothes to younger brothers or sisters.

　　3．Recycle

　　Bottles, cans(罐子) 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 metal 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 apples away, or you could cut off the rotten parts and use 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. 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 repair. It is true that North America is a “throw-away” society, 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.
