Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.
If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.
The best title for this passage is______.
A.The Earth Weight
B.Weight in Space
C.Changing Weight on the Earth
D.Weight on and off the Earth

Today, more than 45 years later, I always check out " It pays to Enrich Your Word Power" first when the Digest comes each month. I am impressed with that idea, word power. Reader's Digest knows the power that words have to move people to entertain, inform. and inspire. The Digest editors know that the big word isn't always the best word. Take just one example, a Quotable Quote from the February 1985 issue: " Time is a playful thing. It slips quickly and drinks the day like a bowl of milk. "
Seventeen words, only two of them more than one syllable, yet how much they convey! That's usually how it is with Reader's Digest. The small and simple can be profound.
As chairman of a foundation to restore the Statue of Liberty, I've been making a lot of speeches lately. I try to keep them fairly short. I use small but vivid words: words like "hope" , "guts", "faith" and "dreams". Those are words that move people and say so much about the spirit of America.
Don't get me wrong. I'm not against using big words, when it is right to do so, but I have also learned that a small word can work a small miracle—if it's the right word, in the right place, at the right time. It's a "secret" that I hope I will never forget.
The passage is mainly about______.
A.one of the many old memories
B.using simple words to express profound ideas
C.Reader's Digest and school speeches
D.how to make effective speeches
A short time later, he awoke; his legs felt _55_ and he was trembling, but, when he opened his eyes, he could see the clock across the room fading in and out in front of him. When his wife entered, he _56_ her for the first time in nine years. Doctors _57_ that he had regained his sight and hearing obviously from the flash of lightning, but they were unable to explain that. The only _58_ explanation offered by one doctor was that, _59_ Edwards lost his sight as a result of trauma in a terrible accident, perhaps the only way it could be restored was by _60_ trauma.

There is much debate about the capacity and duration of the short term memory. The most accepted theory comes from George A. Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or name rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking, or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in "rote rehearsal". By repeating something over and over again, we are able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, you might attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before you get the opportunity to make your phone call, you will forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice "elaborate rehearsal". This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by recognition or recall. Humans can recall memories that are stored in the long term memory and used often. However, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures. , the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization.
According to the passage, how do memories get transferred to the STM? ______
A.They revert from the long term memory.
B.They are filtered from the sensory storage area.
C.They get chunked when they enter the brain.
D.They enter via the nervous system.
Work therefore is desirable, first and foremost, as a preventive of boredom, for the boredom that a man feels when he is doing necessary though uninteresting work is as nothing in comparison with the boredom that he feels when he has nothing to do with his days. With this advantage of work another is associated, namely that it makes holidays much more delicious when they come. Provided a man does not have to work so hard as to impair his vigor, he is likely to find far more zest in his free time than an idle man could possibly find.
The second advantage of most paid work and of some unpaid work is that it gives chances of success and opportunities for ambition. In most work success is measured by income, and while our capitalistic society continues, this is inevitable. It is only where the best work is concerned that this measure ceases to be the natural one to apply. The desire than men feel to increase their income is quite as much a desire for success as for the extra comforts that a higher income can acquire. However dull work may be, it becomes bearable if it is a means of building up a reputation, whether in the world at large or only in one's own circle.
What is the author's opinion about work?
A.Work can keep people busy as if they were poor.
B.Work is a cause of the greatest delight of life.
C.Work is very tiresome, especially when too excessive.
D.Work can at least give relief from boredom.
Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of light. Nothing can move that fast except light itself.
Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.
Light travels more than 186, 000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion(万亿) miles. That great distance is called a light-year. It is used to measure distances in space.
The star closest to our sun is Alpha Centrauri (半人马座a星). It is more than four lightyears away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星)in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years!
Why do we measure the distance in light-years instead of miles?
A.Units of light-years sound better.
B.Using light-years reduced the number of figures used.
C.We used to measure distance in light-years long ago.
D.We do not make mistakes when we use light-years.
