  If you are a fan of the Hollywood blockbuster(大片)Star Wars you must have been enjoying the exciting fights in outer space in recent days. But while you are watching films, the United States is worrying about these fights in real life.

  White House spokesman Scott McClellan said on May 18 the US may change the way it thinks about space. This may mean the restart of the socalled Stars War Program.

  The spokesman said the US “is not looking at armed space,” and is just “making sure US satellites are protected”. But even experts from the US say. “No one should be fooled.”

  Space has become more and more important to the US military. Satellites help soldiers talk to each other, and can show bombs where their targets are.

  It is reported the US Air Force has already developed weapons in space. In April, they sent up a satellite that can stop other nations' military satellites working. Experts argue that if the US sends more weapons into space an arms race may begin.

  “Let's think of a world where the US has dangerous satellites everywhere in space that are going over countries every 10 minutes. Do you think other countries are going to accept that?” said Theresa Hitchens, an American defense expert.

  Many countries have uttered their disagreement, and China is among them. “We are against putting weapons into space,” said Kong Quan, Foreign Ministry spokesman. “We have always held the opinion that space should be used for peace to benefit humankind.”

(1)The subject discussed in this passage is ____.

[  ]

A.the Star Wars movie

B.the US space war program

C.the US satellites

D.the reactions of different countries

(2)What's the excuse for the US to put weapons in space?

[  ]

A.They wanted to defend their satellites.

B.They wanted to fool the world.

C.They are just putting on shows.

D.They want to keep the earth safe from aliens.

(3)What's China's attitude towards the US putting weapons in space?

[  ]

A.China thinks it a great idea.

B.China will declare a war against the US.

C.China will follow the example.

D.China is strongly against it.

(4)The underlined word “uttered” here means “_____”.

[  ]

A.repeated
B.wrote
C.voiced
D.recorded

America hopes to start building a base that can contribute to exist all the time on the moon within 20 years. By the mid-2020s, astronauts will be staying there for six months a time. So what do scientists think food and water will be like for those first moon residents?

In the short term, food would have to be brought from Earth. The dream, however, is to grow things in greenhouses on the moon. “You’d grow things in liquid---there’s no reason why that wouldn’t work,” says Pillinger, a professor. This would mean floating plants in a nutrient-rich solution of water. “Soil is not a necessary thing for plants; it’s only to keep them standing upright,” Pillinger adds.

It would take at least a decade of experiments after the base was built before such a plan would work, however. The main problem is working out how to get nutrients from the lunar(月球的) soil. “Getting all that to work requires a minimum level of infrastructure(基础设施)present before you can start experimenting with greenhouses,” says Pillinger.

Finding strong plants to grow in space will also be hard, though scientists are already working on it: scientist Amy Grunden of North Carolina State University has been working on genetically engineering food crops that can be grown in hars, off- planet environment.

Water is a somewhat easier prospect(前景). One of the reasons that America wants to put its base at the moon’s south pole is that it thinks that, in the permanently shaded craters, there are large pools of frozen water. If that is true, it could easily be mined and used to drink and to create oxygen for the habitants.

 

41. The passage is mainly about______.

A. life on the moon by 2020 

B. America’s first moon base that exists forever

C. food and water on the future moon base 

D. housing for settlers on the future moon base

42. How do people plant on the moon in the future?

  A. By burying plants in the lunar soil

  B. By growing plants in water.

C. By keeping plants standing straight.

D. By making use of the moonlight

 43. What difficulty will scientists meet in solving the food problem?

   A. How to find water to irrigate plants.

   B. Where to experiment with plants.

   A. How to grow plants in the moon soil.

   D. What plants are suitable to grow in the moon

44. Scientists want to build the base on the moon’s south pole because_______.

   A. there is oxygen for people to breathe

   B. people have found the frozen water that can be drunk there

   C. it is a place where water will possibly be found and supplied

   D. there are large pools that can let people have a swim.

This is a dangerous world we live in. The numbers of murders goes up every year; people are dying of cancer;more people contract(感染)HIV;more teens are using drugs;etc. You know this because you’ve heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous.
For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors(肿瘤), is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.
59.In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We got a lot of false statistics from the media.
C. There are around us more and more murders, diseases etc.
D. Statistics alone without full background don’t give us an accurate picture of things.
60.Why does the writer use the example in the second paragraph?
A. To show the danger of reporting only part of the information.
B. To argue that high school students are easily persuaded.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substances(物质)around us.
61.Relative information is often left out because__________
A. relative information is not that important
B. the author is trying to show what he or she says is true
C. too much information will make readers feel confused
D. readers are not able to analyze so much information at once
62.What is the main idea of this passage?
A. Some measures must be taken to protect our dangerous world.
B. We should learn to think critically and look at problems from all sides.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.
