From the passage, we know that the kite celebration _.A. is enjoyable and educationalB. is strict about the shapes of kitesC. gets money from PTO of Piedmont Middle SchoolD. gives people a chance to see kites from around the world53. The passage is intended for _.A. school staff
10、 B. kite expertsC. students and parents D. kite companiesBFrom the very beginning of school we make books and reading a constant source of possible failure and public humiliat
11、ion(侮辱). When children are little we make them read aloud before the teacher and other children, so that we can be sure they “know” all the words they are reading. This means that when they dont know a word, they are going to make a mistake, right in front of everyone. After having taught fifth-grad
12、e classes for four years, I decided to try at all costs to rid them of their fear and dislike of books, and to get them to read oftener and more adventurously.One day soon after school had started, I said to them, “Now Im going to say something about reading that you have probably never heard a teac
13、her say before. I would like you to read a lot of books this year, but I want you to read them only for pleasure. I am not going to ask you questions to find out whether you understand the books or not. If you understand enough of a book to enjoy it and want to go on reading it, thats enough for me.
14、 Also Im not going to ask you what words mean.”The children sat stunned and silent. Was this teacher talking seriously? One girl, who had just come to us from a school where she had had a very hard time, looked at me steadily for a long time after I had finished. Then, still looking at me, she said
15、slowly and seriously, Mr Holt, do you really mean that “I said just as seriously?” I mean every word of it.During the spring she really astonished me. One day, she was reading at her desk. From a glimpse of the illustrations(插图) I thought I knew what the book was. I said to myself, “It cant be,” and
16、 went to take a closer look. Sure enough, she was reading Moby Dick. I said, “Dont you find parts of it rather heavy going” She answered, “Oh, sure, but I just skip over those parts and go on to the next good part.”This is exactly what reading, I think, should be: find something, dive into it, take
17、the good parts, skip the bad parts, get what you can out of it, and then go on to something else.54. According to the passage, childrens fear and dislike of books may result from _.A. reading little and thinking littleB. reading often and adventurouslyC. being made to read too muchD. being made to r

Which statement about the girl is TRUE according to the passage?A. She skipped over those easy parts while reading.B. She had a
20、hard time finishing the required reading tasks.C. She learned to appreciate some parts of the difficult books.D. She turned out to be a top student after coming to this school.来源:学.科.网CRunning on EmptyFor almost a century, scientists have assumed, tirednessor exhaustionin athletes originates(起源于) in
21、 the muscles. Precise explanations have varied, but all have been based on the “Limitations Theory”. In other words, muscles tire because they hit a physical limit: they either run out of fuel or oxygen or they drown in harmful by-products(副产品).In the past few years, however, Timothy Noakes from the
22、 University of Cape Town, South Africa, has examined this standard theory. Tiredness, he argues, is caused not by signals springing from overtaxed muscles, but is an emotional response which begins in the brain. The fundamental nature of his new theory is that the brain paces the muscles to keep the
23、m well back from the edge of exhaustion. When the brain decides its time to quit, it creates unbearable muscle tiredness. This “Central Governor” theory remains controversial, but it does explain many puzzling aspects of athletic performance.A recent discovery that Noakes calls the “lactic acid para
24、dox” made him start researching this area seriously. Lactic acid is a by-product of exercise, and the increase of it is often mentioned as a cause of tiredness. But when research subjects exercise in certain conditions created artificially, they become tired even though lactic acid levels remain low
25、. Nor has the oxygen content of their blood fallen too low for them to keep going. Obviously, something else was making them tire before they hit either of these physiological limits.Noakes conducted an experiment with seven cyclists. It has long been known that during exercise, the body never uses 100% of the available muscle fibre
