阅读理解       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?A. Their chemistry teacher.

举一反三

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. ______________________________________________________

     Lifts are very useful. Why? Think about a tall building you work on the thirtieth floor. Maybe you can
walk up all the stairs one time. But can you climb thirty floors to your office every day? Of course not.

完形填空。       These days, it is easier for us to travel to other countries than ever before. However, there is a big
difficulty that most of us _1_ when we meet people in other countries--we cannot communicate with
them. There are _2_ where English is still not spoken, though it is the most widely known language. So,
wouldn"t it be _3_ if there was one language that could be understood by anyone anywhere in the world?
       Esperanto that was created in 1887 may be the world"s _4_ truly international language. In fact,
although _5_ artificial (人造的) languages have been already created, only Esperanto has had much
success. Its learner say that it is about four times _6_ to learn than other languages. Spelling and
pronunciation are both easy, too. For example, it does not have silent _7_ like the "h" in "hour". If you
_8_ a word, you can spell it without any difficulty.
       The grammar is also as simple as possible: only sixteen basic _9_, no irregular verbs (不规则动词),
only six verb endings. In short, Esperanto should be attractive as a language to learn, _10_ there is a
  problem: how many people have met anyone who can really speak it? Anyway, we hope that some day
one language can be mastered easily by anyone.

The English language we know today is about six hundred years old. For half that time, English was just language of the people living in England. The modem English language grew from about the year 1400. Now English is the most widely spoken language in the world. It is one of the working languages at International meetings, business, science and in other fields. The differences between American English and British English are not very great. Written English is more or less the same in both Britain and America, though there are some spelling differences. For example, centre, licence, colour and travelled are spelt center, license, color and traveled in American English. In America, "cock, rubber, ill, holiday, lorry and post" are called "rooster, eraser, sick, vacation, truck, mail". But people from the two countries can still understand each other easily. There are only a very small number of differences in grammar between American English and British English. Some words may have two kinds of pronunciation. You may wonder "Which is correct?" The answer is that it doesn"t matter. But you should speak either American English or British English. Don"t try to speak both at the same time!
1. When did the modem English language begin to grow? ______________________________________________________________
2. Is English the only working language at International meetings? ______________________________________________________________
3. What is the word "color" spelt in British English? ______________________________________________________________
4. What is the word "ill" called in American English? ______________________________________________________________
5. How many differences are there in grammar between American English and British English? ______________________________________________________________
