题目内容

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(电) 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(毁坏)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.

" Everything happens for the best," my grandmother said whenever things weren't going my way. "Don't worry, one day your luck1._______(change). "

Grandmother was right, as I discovered after graduating from college. I had decided to be sports announcer (广播员) in a radio station, so I 2._______ ( go) to Shanghai and knocked on the door of every station. But I got refused every time.

In one station, a kind lady said my problem was short of experience. " Get some work with a small station and3.______(work) your way up ," she said.

I couldn't get a job there, either. Then my dad told me a businessman had opened a company and needed someone4._______ ( manage) the sports center. But again, I didn't get the job.

I felt really down. "Your luck will change," Granny reminded me. I tried another radio station in Beijing. But the owner, a nice man, told me he already had someone.

As I left his office, I asked, " How can someone be a sports announcer if he 5._______(not, get) a job in a radio station?"

I 6._______( wait) for the elevator when I heard the man call, " What was that you said about sports? Do you know anything about football?" I 7._______(put) in front of a microphone and asked to imagine I was commenting (评论) on a football game. "Now you 8._______ (watch) the football game between Lu Neng and Shen Hua. . . "

Do you know that women’s brains are smaller than men’s? Normally the women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（数量）of “thinking” brain is almost the same in both men and women.

It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.

There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!

The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

1.Which of the following is TRUE according to Paragraph 1?

A. Grey matter controls thinking in the brain.

B. Men’s brain is 10% less than women’s.

C. Grey matter plays the same role as white matter.

D. Men and women have the same amount of white matter.

2.What can you infer from Paragraphs 2 and 3?

A. Men have weaker spatial abilities.

B. Women do not need to tell directions.

C. Women prefer doing many things at a time.

D. Women do many jobs at a time better than men.

3.What can you learn from Paragraph 4?

A. Our children needed more spatial skills.

B. Women may have more feelings than men.

C. Young boys may be stronger than young girls.

D. More women take up jobs requiring speech skills.

4. The passage is mainly about _______.

A. ways of being more intelligent

B. differences between men and women

Kelly Christopher, a student at Lutheran High School in California, US, loves oranges. One day last week, she used a pole(竿子) to pick oranges off trees and collect them in baskets. It's the first time in her 15 years she's picked fruit from trees.

"This is quite different from buying oranges in the supermarket," said Christopher. "Every time I eat an orange, I'll remember this experience."

Christopher was one of the 30 student volunteers at Soil Born Farms. She volunteered as part of a project which was set up in 2009 to help homeowners in South Land Park pick oranges and other fruits out of their backyards. Before, the fruit would rot on the ground or get eaten by animals. Now the fruit is donated to those who need it.

"It is good for many people", said Randy Stannard, who works for the project. "The homeowner gets fruit picked and more people can have healthy food."

"Two harvests (收成 ) were organized in 2009 and volunteers picked 3,000 pounds (1,360kg) of fruit", Stannard said. In 2010, the number was 20,000. This year, Soil Born Farms hopes to get 40,000 pounds. They will harvest every weekend from January to April.

Shannon Galloway, Christopher's science teacher, brought her students into the project this year.

"You're making use of a resource that might be wasted," she said. "I think it's meaningful to everyone."

Donato Frazier, 15, always climbs up a ladder(梯子) and gets on the top of the tree.

"Standing on the treetop is pretty cool," Frazier said. "I can see clearly that many baskets are filled up, and even see that many people are eating healthy fruit because of our volunteer work."

71. Christopher and other students went to pick fruits from real trees because they wanted to _____.

A. The fruit will rot or be eaten by small animals.

B. People who need the fruit will come to pick it.

C. The fruit will be used as a resource for research.

D. Homeowners will pick the fruit and sell it.

3. What does the underlined word “mean?

A. 资源 B. 调查 C. 对策 D. 娱乐

4.How do the students feel about their work?

“What’s the matter, mum?” When I came home yesterday, I found my mother was unhappy. It was unusual—she usually opened the door and welcomed me with a smile. “She’s dying (死),” mum said sadly. I knew what she said. The tulip (郁金香), mother’s favorite, was dying.

A month ago, we moved into our new house and mum bought a very beautiful tulip. Mum liked it very much. Every time she was free, she would sit near the tulip and enjoyed its beautiful color and nice smell. She treated (对待) it like a baby and looked after it carefully. She put the tulip by window and moved it from one place to another to give the tulip enough sunshine. Every morning the first thing she did was to water the tulip. Mum also fertilized (施肥) it many times. She hoped the tulip would become more and more beautiful and stronger. But the tulip was dying because of too much sunshine, water and fertilizer.

It’s true that mother loved the tulip. But this kind of love can be harmful (伤害的). Love can sometimes kill (杀害) what you love.
