30、y keep our air clean, reduce noise pollution, improve water quality and provide food and building materials. Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns(刺)to warn animals not to go near. Most you
31、ng trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more s
32、lowly and begin to produce flowers and fruit. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty; it is also a great place for a tree house, or a place for us to read a book, listen
33、to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years. Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow(空心的)or part of it becomes dead, it provide
34、s a home to small animals and is a source of food for many other animals. In many ways, the life of a tree is similar to our own life experience.

37、ng shows the structure(结构)of the passage?(1=Paragraphl 2=Paragraph 2, )(C) Margaret Knight was born on February 14, 1838, in Maine. She lived during a time when factories were springing up all over the United States and business were booming. Her father died when she was 10 years old and began worki
38、ng in a textile mill(纺织厂). When she was 12, Knight saw an accident in which a part of one of the marhines flew off, seriously hurting a worker. So she decided to plan a way to prevent such accidents. Knight designed a safety feature that would stop the machines if something got caught in them. The m
39、achine soon became common in textile mills and is still used in some factories now. Although factories were willing to use her first invention, Knight did not receive much in the way of reward for her effort. Because of her youth and her familys lack of(缺乏)of education, Knight was unable to patent(获
40、得专利)her safety machine to earn money from selling it. In Knights day, paper bags were shaped like envelopes(信封), which made them difficult to fill. While working at a paper bag factory, Knight thought of bags with flat, rectangular(长方形的)bottom. Then she tried to invent a machine that would produce t
41、hem, and she succeeded. Knight worked for months to perfect her work, but when she asked for a patent, a man named Charles Annan had seen an early model of Knights idea and had tried to patent the machine as his own. Knight insisted that the patent should be hers and ended up taking Annan to court(法
42、庭). During the case; Annan said that a woman would not be able to invent such a complex and innovative(创新的)machine. But Knight provided evidence proving that the machine was hers and received patent in 1871. Knight died in 1914, and one newspaper described her as a woman Edison. At a time when women
43、s hard work and knowledge were taken too lightly, she proved that women too could develop new ideas that would shape the future of industry.( )26. Why didnt Margaret patent her safety machine at first? A. She had no money to do it. B. She didnt consider it worth her effort. C. She expected her inven
44、tion to be of use to all. D. She had no sense of patent at that time.( )27. We can infer from Margrets story that at Margrets time .A. women didnt get well protected at workB. women got badly paid at factoriesC. women werent expected to achieve muchD. women had no right to invent things( )28. Why di
45、d the writer write the passage? A. To tell the importance of role of women in society.B. To call on girls to learn from a woman scientist. C. To encourage women to fight for equal rights.D. To introduce a famous woman inventor in America.(D) Everybody knows that Earth spins from west to east. That i
46、s to say, it appears to be spinning counterclockwise(逆时针)when viewed from above the North Pole. But what if Earth started spinning the other way? Scientists from Germany have made a computer simulation(模拟)in which Earth spins in the opposite direction-clockwise when viewed from above the North Pole.
47、 This showed them some interesting things about the weather and topography(地形地貌)on Earth, live Science reported. As Earth spins in a counterclockwise direction, it shapes ocean currents(洋流).The direction of the spin, together with wind, produces different weather around the globe(全球). But a backward
48、s spin changes the ocean currents and winds. Therefore, the climate(气候)is different. Western areas of continents(大陆)on Earth cool down as the eastern parts warm up. Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planets
