题目列表(包括答案和解析)


Napoga is a 12-year-old girl in Ghana(加纳),Africa. It is hard for her family to get clean water. Every morning,she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can't get enough clean water to keep healthy.
Earth Day is April 22. But on all other days,we must also remember it. The water we use is the most important natural resource(自然资源) on the earth.
Water covers 70% of the earth's surface. But most of that is sea water. We can't use it for very many things. Fresh water covers only 1% of the earth's surface.
You probably feel lucky that your life isn't as hard as Napoga's. But that doesn't mean you don't have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars,factories,farms and homes make our rivers,lakes,and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish,too. Now, 34% of all kinds of fish are dying out.
How do cars and factories make our water dirty?First,they pollute the air. Then,when it rains,the rain water comes down and makes our drinking water dirty. Dirty rain,called acid rain(酸雨),is also bad for plants,animals and buildings.
Scientists say that in 30 years,more than half of the people in the world won't have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
●Turn off the water while you brush your teeth. You can save as much as 450 liters(升) each month.
●Leaky taps(漏水的龙头) waste a lot of water. Fix them right away!
●You can easily cut your 10-minute showers in half----and you'll be just as clean.
●When you wash dishes,don't let the water run.
●Only wash clothes when you have a lot to wash. If your washing machine isn't full,you're  wasting water!
【小题1】On the earth,_______.
A.sea water is more widely(广泛地) used than fresh water
B.there is very little water for our living
C.there is 71% of fresh water
D.we don't need to worry about water
【小题2】Acid rain _______.
A.is only bad for living things
B.can be produced in factories
C.doesn't do harm(伤害) to people,but it's bad for plants,animals and buildings

A.We need ten minutes if we want a clean shower.
B.We should put in enough clothes when we wash them in washing machines.

Making sense of how the US shows humor

Living in a new country gives me many surprises. The first surprise was the way that the US people speak.

One day I saw someone was having a public speech in a square. I thought it would be a serious speech. But I soon found it became a kind of entertainment show.

   The speaker told the audience to protect the environment with humorous words. Later he said some people’s behavior didn’t go with their words. He took the example of Taylor Swift’s song We Are Never Ever Getting Back Together.

   He said that since Swift doesn’t want to be with the boy any more, she doesn’t need to speak it aloud, she doesn’t need to sing unless she still keeps in touch with that guy. It sounds like she is a hypocrite.

   Then he sang the song in a funny way. The audience laughed out loudly. I felt a little angry because Swift is my favourite star. I couldn’t understand why they laughed at Swift.

As time goes on, I find many US people make fun of others. But they don’t mean to hurt them. They do that to show closeness and humour. And people who are laughed at seldom get angry. Now I understand the speaker at the square. Now I’ve got used to the way the US people speak.

   It’s easy to find culture shock when you’re in a new place. But everyone should learn to understand different cultures and customs. 

1.The man in the square was _______________.

A. teaching people how to give a speech

B. calling on people to protect the environment

C. giving a singing show in public

D. criticizing the US government

C. the US people get angry at others easily  

D. the writer doesn’t like the way the US people speak          

4.Which is Not suitable for the passage?

A. The writer went to America and protect the environment.

B. Americans show humour in a different way from China.

C. It’s easy to find culture shock when you are in a new place.

5.What does the article mainly talk about?

“USA? Britain? Which country is better to study in?”
We often hear such discussions. As China opens its door, studying abroad has become a dream for many Chinese students. They would like to know the world well.
It’s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs.
But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language and getting used to a different culture.
Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well.
Finally, studying abroad brings a heavy burden(负担)to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?
We know that there are many famous people who have achieved success through their hard work in China.
Liu Xiang is a good example. Once an American teacher invited him there, but he refused.
He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again.

Old Cremona Violins
Most musicians(音乐家) agree that the best violins(小提琴) were first made in Cremona, Italy, about 200 years ago. These violins sound better than any others. They even sound better than violins made today. Violin makers and scientists try to make instruments(乐器) like the Italian violins. But they aren’t the same. Musicians still prefer the old ones.
Some people think it is the age of the violins. But not all old violins sound wonderful. Only the old violins from Cremona are special(特殊的). So age cannot be the answer.
Other people think the secret to those violins is the wood. The wood must be from certain kinds of trees.
But the kind of wood may not be so important. It may be more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape(形状). The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood.
Size and shape may not be the answer, either. Scientists can make new ones that are exactly the same size and shape. But the new violins still do not sound as good as the old ones. Some scientists think the secret may be the varnish. Varnish is what covers the wood of the violin. It makes the wood look shiny. It also helps the sound of the instrument. But no one knows what the Italian violin makers used in their varnish.
【小题1】The passage is about          .

A.making violinsB.musical instruments
C.scientific ideasD.the old Italian violins
【小题2】Other people think the Italian violin makers          .
A.did not know much about violinsB.were lucky
C.used many kinds of woodD.knew something special
【小题3】Violins made today          .
A.have the same size and shape as the old ones
B.sound the same as the old ones
C.are better than the old ones
D.have the same varnish as the old ones
【小题4】Some scientists believe that the secret of the old violins was          .
A.their soundB.their colourC.their varnishD.the music

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna said.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up(依偎) with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a young lady. The problem is finding out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list,” said Michael Riera, a writer.
“This completely changes during the teen years,” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are the best to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental(脑力的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
【小题1】The underlined sentence in the first paragraph means that __________.

A.the son is always busy with his studies
B.the son doesn’t want to see anymore
C.the son keeps himself away from his parents
D.the son wants to live with his friends

A.their daughter isn’t as happy as before
B.they can’t understand what their daughter thinks
C.they don’t know what to say to their daughter
D.their daughter talks far more to her friends than to them
【小题3】“The wall of silence” in the first paragraph means that __________.
A.teenagers talk a lot with their friends
B.teenagers do not talk with their teachers
C.teenagers do not talk much with their parents
D.teenagers talk little about their studies
【小题4】The better way for parents to know their children is to be a ________.
A.teacher B.friend C.manager D.student
