How men first learnt to invent words is unknown; in other words, the origin of langua

ge is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thought and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to present those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their associations - the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar. What is true about words？

：A、They are used to express feelings only

B、They can not be written down

C、They are simply sounds

D、They are mysterious.

Physicists were thinking far ahead of their time in a very intelligent way．They saw what w

as going to happen before it actually did．They thought about modern computing in the 1950s，they imagined a lot of the technological progress that we would see only decades later in the real world．They were asking very theoretical questions because these ideas were still so far removed from practice．And they asked very moral questions as well，because the things they conceptualized could be used for great good or for great evil．It could go either way，so moral judgments had to be made．

Passage Two

How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, by their position and association, can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech dull and silly.

Which of the following did men invent first？

A．Words.

B．Sounds.

C．Signs.

D．Letters.

May be you have seen this in schools: some students are studying nearly all the time

but they just pass their exams, while some others may spend much less time on their books but do much better in exams. How could this happen？ People used to think that hard work is the only way to success. But now they have understood that smart work can make them succeed too. Hard workers don’t mind working for long hours, while smart workers always think of several different answers to these questions, such as “Why should I suffer this？ ” or “Isn’t there a way to do this？ ” Thanks to these people, we can use computers instead of the abacus now. progress in every field is the direct result of “trying to find a better way ” by smart workers. There was a large soap factory in Japan. Once it received an unusual letter from someone who complained that there was no soap in the soap in the soapbox he bought.How could empty soapboxes go out of the factory？ The engineers checked the producing and packing. The producing was fine, but in about ten thousand soapboxes, the packing machine let an empty soapbox go. There was no need to spend a lot of money repairing the machine for such a small problem. The engineer soon worked out a solution. He put a huge X-ray machine and two large computers to find out the empty soapboxes. After teaching the workers how to use it, he sat down in his seat, exhausted.

“Sir, we could have solved the problem in a much simpler and cheaper way, ” a worker sa id.

“Really？ How？”

“We can put a huge fan near the packing machine. The wind coming from the fan will blow away the empty boxes, leaving the other boxes with soap. ”

See, this is smart work. In order to succeed, we should not only work hard like the engineer, but also think smart like this worker.

1. Some students spend less time on school work but do better in exams because they study longer.

A: F

B: T

2.The passage mainly tells us we should work hard like the engineer and think smart like theworker.

A: T

B: F

3.The soap factory could only put a huge fan near the packing machine to solve problem in amuch simpler and cheaper way.

A: F

B: T

4.The underlined phrase “blow away”means “停止” in Chinese.

A: T

B: F

5.Someone wrote to the soap factory and complained that the soapbox he bought was terrible.

A: F

B: T

第10题

Because we can feel that things are heavy, we think of weight as being a fixed quality in

an object, but it is not really fixed at all. If you could take a one pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound.

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
