‎2019高考英语二轮阅读理解讲与练（解析）-科普知识与现代技术（2）‎ ‎·专项训练 ‎ A ‎ Inventor, physicist, surveyor, astronomer, biologist, artist … Robert Hooke was all these and more. Some say he was the greatest experimental scientist of the 17th century. In the course of his work, he cooperated with famous men of science like Isaac Newton, and the great architect, Christopher Wren. Hooke’s early education began at home, under the guidance of his father. ③He entered Westminster School at the age of 13, and from there went to Oxford, where he came in contact with some of the best scientists in England. Hooke impressed them with his skills at designing experiments and inventing instruments. In 1662, at the age of 28, he was named Curator of Experiments at the newly formed Royal Society of London — meaning that he was responsible for demonstrating new experiments at the society’s weekly meetings. Hooke accepted the job, even though he knew that the society had no money to pay him! him in appreciation of his services to this branch of science. ‎ ‎1. We can infer from Paragraph 2 that Hooke is ____.   A. friendly  B. sociable C. creative D. helpful 2. Why possibly did Hooke accept the job as Curator of Experiments?   A. Because his parents couldn’t afford his education.   B. Because his family needed his support. C. Because he wanted to please the famous scientists in England.   D. Because he liked designing experiments. 3. The cell got its name because of ____.   A. its use B. its shape C. Hooke’s favorites  D. Hooke’s experiences 4. The last paragraph is to prove that ____. A. Hooke was the greatest experimental scientist of the 17th century B. Hooke was good at making discoveries C. Hooke’s contributions were not limited to one filed D. Hooke was one of the greatest astronomers 5. The best title for the text may be ____. A. The Greatest Scientist B. A Helper of Newton C. A Brief Introduction to Hooke D. Achievements of Hooke B Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy ;there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiousness . Firstly ,listen to their questions. I once visited a classroom of seven year olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence.Finally I said,“Now that we’re ‎ finished with your lists ,do you have questions of your own about science?”  After a long pause, a boy raised his hand,“Have you ever seen a grasshopper(蚱蜢)eat? When I try eating leaves like that, I get a stomachache. Why?”  This began a set of questions that lasted nearly two hours. Secondly ,give them time to think. ④Studies over the past 30 years have shown that ,after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more ,children give more logical , complete and creative answers. Thirdly, watch your language .Once you have a child involved in a science discussion, don’t jump in with ‎ ‎“That’s right” or “Very good”.These words work well when it comes to encouraging good behavior .But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”,or coming up with more questions or ideas. Never push a child to “Think”.It doesn’t make sense, children are always thinking, without your telling them to. What’s more ,this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement. Lastly, show; don’t tell. Real life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜),and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发),set a pot of water to boil and let them watch the water level drop. ‎1.According to the passage , children are natural scientists, and to raise their interest, the most important thing for adults to do is ____________. A. to let them see the world around B. to share the children’s curiosity C. to explain difficult phrases about science D .to supply the children with lab equipment ‎2.In the last sentence of the first paragraph, the word “lists” could best be replaced by ____________. A. any questions B .any problems C .questions from textbooks D .any number of questions ‎3.

The secret may lie in the head, not in the stomach, US researchers reported. Tests on rats show that the appetite hormone Ghrelin(释放激素释放肽) acts on pleasure receptors (感受器) in the brain. The findings may help researchers develop better diet drags.‎ ‎ “In mice and rats, Ghrelin excites the same neurons (神经细胞) as delicious food, that is, neurons that provide the feeling of pleasure and the expectation of reward,” the researchers write in the Journal of Clinical Investigation. “These neurons are located in a region of the brain known as the ventral tegmental area (VTA)," wrote the researchers, headed by Dr. Tamas Horvath of the Yale University School of Medicine in Connecticut.‎ ‎ Horvath's team found that Ghrelin, which is only discovered in the last decade, acts on a molecular structure on brain cells called the growth hormone secret receptor or GHSR for short.‎ ‎ ⑤When Ghrelin was put into this area of the rats' brains, they ate as hungrily as they did after being kept hungry overnight, the researchers said. Ghrelin is produced in the gut (肠道) and causes the brain to promote eating.‎ ‎ Several hormones are known to be involved in eating and appetite, and studies have shown that influencing them can affect weight gain in rats and mice. Influencing human eating behavior has proven far more difficult, however.‎ ‎ Horvath said it might be possible to design a drag that interferes with GHSR and thus help people with eating disorders.‎ ‎1.
