1、He was turned into ashes. But not his notebook. Dear readers, this is a true story. That man was none other than our respected maths master Srinivasa Ramanujan. That notebook I was talking about was full of new mathematical discoveries but without any proofs(证明)of them. Though he had almost no forma
2、l training in pure mathematics, Ramanujan made great contributions to it, including solutions to mathematical problems considered to be unsolvable. During his short life, Ramanujan independently produced nearly 3, 900 results. His work has opened entirely new areas of mathematics and inspired a vast
3、 amount of further research. Nearly all his claims have now been proven correct. We lost him at a very young age of 32 years. What he could have accomplished if he would have lived for some more years! 【文章大意】这是一篇记叙文。文章讲述了Ramanujan在生命的尽头不忘继续书写自己的梦想新的数学发现, 后被数学界所认可而且将被继续研究。21. What are the dreams he k

He received no formal training in mathematics. C. He proved many unsolvable mathematical problems. D. H
6、e stopped studying maths and returned home because of illness. 【解析】选B。根据第六段的Though he had almost no formal training in pure mathematics. . . 可知, Srinivasa Ramanujan没有受过正规的数学训练。故选B项。23. What might be the authors attitude towards Ramanujans death?A. Inspired. B. Shocked. C. Guilty. D. Sorry. 【解析】选D。推理
7、判断题。根据最后一段“我们在他32岁的时候就失去了他。如果他能多活几年, 他会取得多大的成就啊! ”可知, 作者对于Ramanujan的去世深表遗憾, 故选D项。BThe birth of Britains first cloned dog has been considered “a waste of money” and scientists said the process raised serious ethical (伦理的) concerns. Sooam Biotech, a company in Seoul, said it had cloned the puppy, name
8、d Mini-Winnie, from a 12-year-old dog belonging to Rebecca Smith, who lives in the west London. She had won a contest run by the company which hoped to sell the service to pet owners for 60, 000 pounds a time. Mini-Winnie was born after scientists took skin cells from Smiths pet and dropped them int

But researchers warned that while a cloned dog might look similar to its biological parent, it would be a very different animal. “You would have many chances of repli
10、cating (复制) your favorite pet by choosing one from Battersea Dogs Home, ” said Robin Lovell-Badge, a geneticist at the National Institute for Medical Research in London. Dusko Ilic, a stem cell scientist at Kings College London, said, “It is extremely unlikely that a puppy cloned from a favorite pet
11、 will behave in the same way. As time passes by, the differences will be more and more pronounced, especially personality traits. It is an absolute waste of money. ”The cloning process is controversial (有争论的) because the animals are often born with diseases or die soon after birth. I think, its unne
12、cessary to try to clone pets for pet owners. First, its really costly. Second, the cloned pet is actually another dog. Third, there are many homeless dogs for people to adopt in shelters. So why not just adopt a dog instead?【文章大意】这是一篇议论文。作者主要以英国出生的第一只克隆狗为例, 以及引用多方人士的评论来证明自己认为克隆宠物是完全没有必要的。24. What ma
13、y be the reason for Sooam Biotechs work on cloning pets?A. To pay back to society. B. To make money out of it. C. To comfort sad pet owners. D. To win an important contest. 根据第二段的She had won a contest run by the company which hoped to sell the service to pet owners for 60, 000 pounds a time. 可知这只克隆的
14、小狗赢得了该公司举办的一项竞赛, 该公司希望将这项服务以6万英镑的价格卖给宠物主人。由此可见Sooam Biotech克隆宠物的原因是从中挣钱。25. Why doesnt the cloned dog enter Britain now?A. Because people in Britain are against it. B. Because the company is afraid that it will die. C. Because it needs to stay in Republic of Korea for research. D. Because British qu
15、arantine laws dont allow it. 根据第三段的The puppy must remain in Republic of Korea for six months to satisfy British quarantine laws. 可知克隆狗现在不进入英国的原因是这只小狗必须在韩国待六个月, 以符合英国的检疫条例。26. What can we learn from what Dusko Ilic said in Paragraph 4?A. Cloned pets are usually not lovely. B. Cloned pets can be very
16、disappointing. C. Its possible to replicate ones favorite pet. D. A cloned dog looks similar to its biological parent. 根据第四段中It is extremely unlikely that a puppy cloned from a favorite pet will behave in the same way. . . It is an absolute waste of money. 从最喜欢的宠物身上克隆出来的小狗几乎不可能有同样的行为。这完全是浪费钱。可知Dusko
17、 Ilic对这种克隆狗的存在并没抱有积极的态度。27. According to Paragraph 5, why is the cloning process controversial?A. It is costly. B. It is too difficult. C. It can spread diseases. D. The result is unsatisfactory. 根据第五段的The cloning process is controversial because the animals are often born with diseases or die soon
18、after birth. 克隆过程是有争议的, 因为动物往往生下来就有疾病或不久便会死去。可知, 结果并不令人满意。C(2020无锡高二检测)Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people on the front end of a technological shift. It is not always the case, though. When you look
19、at attitudes toward driverless cars, there doesnt seem to be a clear generational divide. The public overall is split on whether theyd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not. The fact that attit
20、udes toward self-driving cars appear to be so steady across generations suggests how varying the shift to driverless cars could be. Not everyone wants a driverless car nowand no one can get one yetbut among those who are open to them, every age group is similarly involved. Actually, this isnt surpri
21、sing. Whereas older generations are sometimes reluctant to adopt new technologies, driverless cars promise real value to these age groups in particular. Older adults, especially those with limited moving or difficulty driving on their own, are one of the classic use-cases for driverless cars. This i
22、s especially interesting when you consider that younger people are generally more interested in travel-related technologies than older ones. When it comes to driverless cars, differences in attitude are easily noticeable based on factors not related to age. College graduates, for example, are partic
23、ularly interested in driverless cars compared with those who have less education, 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less. Where a person lives matters, too. More people who live in cities and s
24、uburbs said they wanted to try driverless cars than those who lived in rural areas. While theres reason to believe that interest in self-driving cars is going up across the board, a persons age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually
25、 available for sale, the early adopters will be the people who can afford to buy them. 【文章大意】本文介绍了一个新科技, 无人驾驶汽车, 这项科技受到各个年龄段的人的欢迎。28. What happens when a new technology appears?A.
