1、Will We Take Vacation in Spaces?
When Mike Kelly first set out to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."
According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits for a two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) set to actor by 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "
This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support or return trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. And that doesn't include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entire group of entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive for the little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space's prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can't be too prepared, for a trip
to that galaxy far, far away.
For those who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite.
Some of the hurdles space tourism faces include a lack of oxygen and life support equipment.

3、The Value of Advertisement
Money spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide for export at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more.
And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people for a little while
through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor goods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised for it, and that it has good value.
Advertising does more for the good of the public than any other force I can think of.
There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade.
If its messages were nothing but information, that would be difficult to get more people to buy, for even the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.
Which of the following is the most important advantage according to the passage?
【单选题】
A.Reducing the cost of your daily newspaper.
B.Lowering the price of your television program.
C.Making it possible to provide for export at good price.
D.Providing a promise of reasonable value in the products and services you buy.
正确答案:D
答案解析:选项A、B、C、D都是提到的好处，但是从文章第2段第1句可知，最重要的是广告能提供产品和服务的价值承诺。

因此选D。

5、What Is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in
Antarctica (南极洲) in 1983.
We encounter an interesting situation when we discuss temperatures in space.
Temperatures in Earth orbit actually range from about +120℃
to - 120℃. The temperature depends upon whether you are in
direct sunlight or shade. Obviously, -120℃is colder than our body can safely endure. Thank NASA science for well, de signed space suits that protect astronauts from these temperature extremes.
The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it
depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work, not a discovery, in this case.
Why is the two scientists' work so important to science?
In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein's calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.
Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world's atomic clocks even more accurate. These clocks are so accurate today they would only lose one second ______ six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.
【单选题】
A.any
B.each
C.some
D.every
正确答案:D
答案解析:本题有一定难度，考查不定代词every的用法，干扰项有一定的干扰。

根据上下文逻辑，文章此处是说“……每六百万年仅差一秒”，each后面不能跟复数名词，因此最佳答案是D。
