Many people have heard of Franklin's famous kite experiment, but not many know how to do the experiment themselves. To repeat Franklin's 1 , first make a kite. Use a handkerchief 2
of silk, which is 3 to withstand the wind and rain. Build a frame by making a cross of two pieces of 4 wood, just long enough to reach the corners of the 5 . Tie the corners to the points of the frame, and then attach a tail of cloth 6 your kite. Finish with a good strong kite string, one 7 will be long enough to fly the kite high.
To get the kite ready for the experiment, there are three very important 8 .

Stephen Hawking, arguably the most famous scientist alive today, cannot write on paper and cannot even hold a pen. His disabilities, however, have not affected his mind. Hawking is able to grasp some of the most complex concepts known to man and somehow simplify them for others.
Hawking was born i ( http: / / www.21cnjy.com )n Oxford, England on January 8, 1942. When he was about 8 years old, his family moved to the town of St Albans, about 20 miles to the north of London, where he attended St Albans school at the age of eleven. Hawking then attended his father's old college, University College. Stephen wanted to do mathematics, which was not available at University College, so he did physics instead. He earned a degree in Natural Science with first class honours in just three years. Hawking then headed to Cambridge to study Cosmology. He completed his PhD and then stayed on at Cambridge at first a Research Fellow and then a Professor Fellow. In 1973, Hawking moved from the Institute of Astronomy to the department of Applied Mathematics and Theoretical Physics. In 1979, he was given the post of Lucasian Professor of Mathematics, which he continues to hold to this day. He is today a fellow of the Royal Society and a member of the US national Academy of Sciences.
Hawking's great int ( http: / / www.21cnjy.com )erest has been to understand the basic laws that our universe follows. One of his most well-known achievements was to demonstrate, along with Roger Penrose, that Einstein's theory of general relativity needed to be brought together with quantum theory. Hawking and Penrose showed that if Einstein's theory was carried out logically, space and time must have begun in something like the “Big Bang” of evolutionary theory and must end in black holes.
Hawking has received numerous medals, awards and other prizes for his work. He is known today not only among professional scientists but also by the general public. He has published several books specially written to try to explain his theories to the common man. Three of his most popular books are his bestsellers A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell. Hawking continues to research and write, not letting his disabilities slow him down. His goal is simple, he says. He simply wants “a complete understanding of the universe. Why it is as it is and why it exists at all.”

But unlike Yang's flight, which the public did not get to see much of, much of Shenzhou 6 mission from lift-off to landing was shown live on national Chinese television. With Shenzhou 6, China has “achieved another milestone … in … space exploration,” said Wu Bangguo, Chairman of the Chinese NPC during his speech which was broadcast live on CCTV.

A. 2003. B. 2004. C. 2005. D. 2006.

参考范文：
With the development ( http: / / www.21cnjy.com ) of space technology, human beings are exploring further into the space. Those space experiments and explorations cost huge sums of money, which, quite a number of people think, should have been used to protect human natural environment and solve the problems we all are facing. This might be true, but I think in the long run human will have to turn to other planets when all the resources are used up. For example, human could make use of the mines on the moon and conduct special experiments in the space. Moreover, some of the new technologies employed in space could be used in our daily life and thus creating a better life for us.
All in all, space ( http: / / www.21cnjy.com ) technology development is sure to benefit all human beings.

English is fast becoming the language of science around the world, but what is its future among everyday speakers One expert points out that the percentage(比率) of native English speakers is declining(降低) globally while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important.
However, British ( http: / / www.21cnjy.com ) language scholar David Graddol says English will probably drop in dominance(主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. “The number of people speaking English as a first language continues to rise, but it isn't rising nearly as fast as the numbers of many other languages around the world, simply because the main population group has been largely in the less developed countries where languages other than English have been spoken,” he says.21世纪教育网
In a re ( http: / / www.21cnjy.com )cent article in the journal Science, Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay, spoken in south and Southeast Asia.
David Crystal, th ( http: / / www.21cnjy.com )e author of the Cambridge Encyclopedia of the English Language, says about 1.5 billion of the world's six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future of its dominance. “Nobody quite knows what's going to happen because no language has been in this position before. But all the evidence (证据) suggests that the English language snowball is rolling down a hill and is getting faster,” he said.
36. In David Graddol's opinion, English will _______.
A. remain widespread and important
B. be more important than any other language 21*cnjy*com
C. lose its dominant position
D. die away in the near future
37. The underli ( http: / / www.21cnjy.com )ned sentence in the last paragraph implies that ______.【来源：21cnj*y.co*m】
A. snowballs will roll down faster than language balls
B. the English ( http: / / www.21cnjy.com )language snowball is rolling down faster than any time in the past
C. English language will soon drop in dominance
D. more and more language users will choose English
38. How many exp ( http: / / www.21cnjy.com )erts does the passage mention who express their ideas about the future of English 21世纪教育网
A. 2. B. 3. C. 4. D. 5.
39. According ( http: / / www.21cnjy.com ) to David Graddol, which of the following will possibly be one of the languages that will be most widely spoken 21·世纪*教育网
A. Malay. B. Arabic. C. Urdu. D. German.
40. What should be the best title for the passage 21cnjy.com
A. English Remaining the Dominant Position21世纪教育网
B. The Future of English Who Knows
C. Opinions from Different Experts
D. The English Language Snowball Rolling Down
B
Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
It is a problem we ( http: / / www.21cnjy.com ) need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.
41. Before children start speaking________.
A. they need equal amount of listening
B. they need different amounts of listening
C. they are al ( http: / / www.21cnjy.com )l eager to cooperate with the adults by obeying spoken instructions
D. they can't understand and obey the adult's oral instructions
42. Children who start speaking late ________.
A. may have problems with their listening
B. probably do not hear enough language spoken around them
C. usually pay close attention to what they hear
D. often take a long time in learning to listen properly
43. A baby's first noises are ________.
A. an expression of his moods and feelings
B. an early form of language
C. a sign that he means to tell you something
D. an imitation of the speech of adults
44. The problem of de ( http: / / www.21cnjy.com )ciding at what point a baby's imitations can be considered as speech________.
A. is importan ( http: / / www.21cnjy.com )t because words have different meanings for different people
B .is not espec ( http: / / www.21cnjy.com )ially important because the changeover takes place gradually
C. is one that sho ( http: / / www.21cnjy.com )uld be properly understood because the meaning of words changes with age
D. is one that should be completely ignored（忽略）because children's use of words is often meaningless www-2-1-cnjy-com
45. The speaker implies________.
A. parents can never hope to teach their children new sounds21教育网
B. children no longer imitate people after they begin to speak
C. children who are good at imitating learn new words more quickly
D. even after they have learnt to speak, children still enjoy imitating【出处：21教育名师】
