阅读下面一篇短文,判断下列句子是否符合短文内容,符合的用"A",不符合的用"B"。       Today more and more people are using refrigerators. Some are big, others are small. Big ones have
  two or three doors. Such refrigerators can not only keep the food cold and fresh, but also make ice and
  freeze the food.  However, small ones usually have one door and can only keep things cold and fresh.
       There are also refrigerators that are friendly to the environment. In the 1970s, the world was in energy
   crisis (危机). Refrigerators use too much energy. So people began to think of ways to improve it. At last
  a kind of new refrigerators was made. They use very little energy, but they"re too expensive. They cost
  twice or three times more than the ones that we use at home. However, people believe they will be
  cheaper and cheaper. As a result, they will be more and more popular.
       In the future, there will be refrigerators that can do more than we can imagine. They are called smart
  refrigerators (智能冰箱). They have tiny computers inside, with their screens on the door. They can
  show us what food is inside. They can also tell us what food to buy. They can even let. us know what
  food to eat when we input the necessary health information. That more surprising thing is that they can do
  shopping for us when they are connected (连接) to the supermarket.(     )  l. Small refrigerators can not only keep the food cold but also freeze the food.
(     ) 2. Refrigerators that use little energy are more expensive.
(     ) 3. Environment friendly refrigerators. will be popular some day.

阅读下文,从各小题所给的四个选项中选出能回答所提问题或完成所给句子的最佳答案。
     There have been many great inventions or things that changed the way we live. The first great invention
  was the one that is still very important today-the wheel. This made it easier to carry heavy things and to
 travel long distance.
     For hundreds of years after that there were few inventions that as much effect as the wheel. Then in the
  early 1800s the world started to change. There was little unknown land left in the world. People didn"t
 have to explore much any more. They began to work instead to make life better.
     In the second half of the 19th century many great inventions were made. Among them there were the
 camera, the light and the radio. These all play a big part in our daily life today.
    The first part of the 20th century saw more great inventions. The helicopter in 1909, movies with sound
  in 1926, the computer in i928,jet planes in 1930. This was also a time when a new material was first
 made. Nylon came out in 1935. It changed the kind of clothes people wore.
     The middle part of the 20th century brought new ways to help people get over diseases. They worked
  very well.  They made people healthier and allowed them to live longer. By the 1960s most people could
  expect to live to be at least 60.
     By this time most people in developed countries had a very good Life. Of course new inventions
  continued to be made. But man now had a desire (渴望) to explore again. The earth was known to man
  but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then
  United States took a step. Since then other countries, including China and Japan, have made their own
 steps into space.
      In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is
 certainly just a beginning, though. New inventions will some day allow us to do things we have never yet
  dreamed of.
1. This passage talks mainly about ______.
    A. why cars were very important
    B. when light was invented
    C. how inventions affect people"s daily life

    A.  at the beginning of 1800s  
    B.  in the 1960s
    C. since the 1900s            
    D. from the 1800s to 1960s
3.  In the 1800s, people began to work in order to make ______.
    A. explorations             
    B. their life better
    C. discoveries

       Three kids have been learning chemistry for only a few months. But they have already begun to
challenge a world famous scientist!
       Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
       "We"ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
       British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
       But when the kids did some experiments in class last winter, they saw that the litmus paper didn"t turn very blue with base matter. It"s hard to get a clear result.
       Will there be a better indicator than litmus paper? The three kids decided to try and find out!
       How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨)
leaves, flowers and stems (茎) to get the pigments (色素) from them.
       The kids mixed pigments with acid and base. They spent months watching carefully to see which
paper showed the best colour change. They decided it was the litmus paper!
       "It"s our first scientific journey, Huang said, "But it makes me want to try harder."
1. Whom did the three kids want to challenge?

阅读短文,根据要求完成下面各小题。
       In a classroom in any countries, the teacher teaches more than art or history or language. He or she
teaches something behind-the culture(文化)of the country.
In a country such as the United States, people with different history, culture and language join together
and they pay much attention to personal ideas. Teachers try to make each student special. Students do
not have to remember a lot of information, instead, they work and find answers by themselves. There is
often discussion in the classroom. 
       At an early age students learn to have their own ideas. Their education encourages personal thought(思想). 
       (3) The importance is placed on how to arrive at an answer and not only to get the correct answer.
       In most Asian countries, people have the same language, history and culture. Perhaps for this reason,
the education there pays more attention to group goals than personal ideas. Children in China and Japan
often work together and help each other on homework. In the classroom, the ways of teaching are often
very traditional. The teacher says, and the students listen. There is not much discussion. Instead, the
students repeat(重复) rules or information that they have been taught in order to keep them in mind.
In many ways these differences come from different educational ideas. In Western countries teachers are
taught to help students to learn. They make it easier for the students to learn by themselves. (4) In some Asian countries, however, teachers often feel that their job is to pass knowledge to students.
(一)根据短文内容简要回答问题。
1. What does the education in the United States encourage?
                                                                                                               
2. Which does the education in some Asian countries pay more attention to, group goals or personal
ideas?
                                                                                                               
(二) 将短文中划线的句子译成汉语。
3. ______________________________________________________
4. ______________________________________________________
(三)请给短文拟一个适当的标题。
5. ______________________________________________________
