Every time you turn on the television or take a ride in a car ,you could be adding to a problem called acid rain(酸雨). In this article, you’ll learn how acid is created, and how it affects us, and more importantly, what we all can do to prevent it.

How is acid rain created?

When people use fuels(燃料), such as coal and gasoline, poisonous gases are given off. When these gases mix with rain, acid rain forms. Many power stations burn fuels in order to create the electricity(電) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline .When rain mixes with these gases, harmful things called acids form. This is acid rain.

How does acid rain affect us?

Acid rain damages(毀壞)everything that it touches. It poisons our rivers, ponds, lakes, and oceans along with all the life in them. It pollutes our soil and crops, harms trees, and can even kill fish and plants. Acid rain also eats away at buildings.

How can we prevent acid rain?

We need to cut down on the pollution that gets into our air. Turn off lights, television, and other electrical appliances if you are not using them, Walk or take a bike whenever possible. If you are travelling a long distance, take a bus or train to save fuel.

As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.

1.When power stations burn fuel, _______.

A.a(chǎn)cid rain form                          B.a(chǎn)ir pollution is caused

C.noise pollution is caused                  D.a(chǎn)cid rain gets heavier

2.What advice does the article give us?

A.Go to school on foot or by bike if we can.

B.Go to bed earlier in order to use less electricity.

C.Travel by bus to prevent acid rain.

D.Turn off the television on rainy days.

A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds, they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is chemical.
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighboring plants. These chemical warnings can spread information about one plant’s disease or infestation(蟲害), so other plants can protect themselves. But how plants receive and act on many of the information exactly is still mysterious.
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest(害蟲). To start out, they grew plants in two separate plastic spaces connected by a tube(管子). One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed(暴露) to the pest. The results showed that plants near sick neighbors before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic come from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbors.
It is not a simple story, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
小題1:The underlined “traced” in the fourth paragraph probably means _________ here.
A.reportedB.followed
C.doubtedD.developed
小題2:For scientists, which are the right steps to watch tomato plants infested by a pest?
①  Place the infested plant upwind.
②  Place the uninfested plant downwind.
③  Expose the downwind plants to the pest.
④  Grow plants in two separate plastic spaces connected by a tube.
A.③①②④B.①④③②
C.④①②③D.④②①③
小題3:You can put the sentence “The researches also studied leaves from exposed plants and unexposed plants.” At the beginning of
A.Paragraph 3B.Paragraph 4
C.Paragraph 5D.Paragraph 6
小題4:Which of the following can be the best title of this passage?
A.Communicating Plants and Terrible Diseases
B.Talking Plants and Friendly Warnings
C.Protecting Plants and Clear Information
D.Growing Plants and Mysterious Chemicals
