How does a place become a World Heritage Site? It takes a lot of people to decide.

1）If a country wants one of its places to be on the World Heritage List, it has to ask UNESCO. The place must be important and special. UNESCO put the Great Wall on the list in 1987 because, it said, it was a great part of Chinese culture and beautifully made to go with the land．When a country asks, it must also make a plan for taking care of the place.

2）The World Heritage Committee of UNESCO talks about different places and decides whether to put them on the list. The committee meets every June. Many experts help the committee to decide.

3）After a new place goes on the list, UNESCO gives money to help keep it looking good．If a place is in serious danger, it may be put on the List of World Heritage Sites in Danger. UNESCO gives special care and help to those places.

4）Countries have to give UNESCO regular reports about places on the list. If UNESCO thinks a country isn’t taking good enough care of a place, the site will be taken off the list.

1.The passage implies that _____.

  A. becoming a world heritage site takes hard work

  B. a place with beautiful scenery is often on the World Heritage List

  C. a place which was taken good care of is often on the World Heritage List

  D. the Great Wall became a World Heritage Site for its long history.

2.If a place successfully becomes a World Heritage Site, the country _____.

  A. can ask UNESCO for more money and help

  B. should continue to take special care of it

  C. won’t take trouble of caring for it

  D. will try to put it on the List of World Heritage Sites in Danger

3.The passage mainly discusses ______.

  A. how the World Heritage Committee of UNESCO decides a World Heritage Site

  B. how the World Heritage Committee of UNESCO protects a World Heritage Site

  C. how the Great Wall becomes a World Heritage Site

  D. how a place becomes a World Heritage Site

4.The purpose of putting a place on the World Heritage List is _____.

  A. to attract more tourists from other countries

  B. to get more money and help from other countries

  C. to have it taken better care of

  D. to make it known to other countries

 

 

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

1．What makes a scientist according to the passage?

A. The tools he uses.                                                      B. His ways of learning.

C. The way he uses his tools.                      D. The various tools he use

2．“The scientist, however, goes one step further,” the author says this to show________.

A. the importance of information                               

B. the importance of thinking

C. the difference between scientists and ordinary people

D. the difference between carpenters and people with other jobs.

3．A sound scientific theory should be one that________ .

A. does not only work under one set of conditions at one time, but also works under the same conditions at other times                                      

  B. leaves no room for improvement

C. does not allow any change even under different conditions  

D. can be used for many purposes

4．What is the main idea of the passage?

A. Scientists are different from ordinary people.            

 B. The theory of relativity.

C. Exactness is the core（核心）of science.

D. Exactness and way of using tools are the keys to the making of a scientist.
