题目:

据报:中国的消费增长速度惊人,2003年中国成品钢材消耗量已经大约2.5亿吨,20年增长8倍,为美国、日本、德国和法国钢铁消耗量总和的98.65%,约占世界总消费量的22.8%水泥消费量约8亿吨,约为1983年的8倍,占世界总消耗量的48.9%左右;而能源消耗却占了30%,我国单位产值电能消耗为0.15千瓦时/元,是美国的3倍,日本的5倍,2003年我国电力消费为18043.5亿千瓦时,已经超过日本,居世界第二位,仅低于美国,但中国的GDP占世界的却不到5%。从资源利用效率来看,以单位GDP产出能耗表征的能源利用效率,中国与发达国家差距非常大,日本为1,意大利为1.33,法国为1.5,德国为2.17,英国为2.67,美国为3.5,而中国高达11.5,中国的耗能设备能源利用效率比发达国家普遍低30%~40%,每1000美元GDF排放的二氧化硫:美国为2.3千克,日本为0.3千克,而中国高达18.5千克;从资源再生角度看,中国人均水资源拥有量仅为世界平均水平的1/4,但水资源循环利用率比发达国家低50%以上,中国的废旧轮胎再生利用率仅有10%左右,远低于发达国家。

2003年,按当时美元与人民币的银行汇率100:849计,我国消耗的电力所产生经济效益为多少亿美元()。

A.120290

B.14168

阅读理解。

     Many people go to school for education. They learn language,history,politics,math and so on. Others go

to learn a skill so that they can find a job. School education is very important and useful. Yet, no one can learn

everything from school. A teacher can't teach his students everything. The teacher's job is to show students

how to learn. They teaches them how to read and how to think. So the students shall learn much more outside

school.

     It's always more important to know how to study by oneself than to remember some facts or formula

(公式). It is certainly quiet easy to learn a certain fact in history or a formula in math. But it is very difficult to

use a formula in working out a math problem. Great scientists before us didn't get everything from school.

Their teachers only showed them the way. The reason for their success is that they knew how to study. They

read books more than taught at school. They would ask many questions as they read. They worked hard all

their lives. Most important is that they knew how to use their brain. (大脑).

根据短文内容,回答下列问题。

1. What do you go to school for as a student?

4. Why were many so successful ?

                                                                                           

5. 用短语或简洁的句子回答:

    How did great scientists study?

    例如:Read a lot of books.
