1、課 時 作 業(yè) .閱讀理解(2019煙臺一中高三適應(yīng)性考試)China became the first country to clone a monkey using nonreproductive cells, reducing the need to breed lab monkeys and paving the way for more accurate, effective and affordable animal tests for new drugs, scientists said on Thursday.By December, the Institute of Neur
2、oscience of the Chinese Academy of Sciences had created two clone macaques(獼猴) named“Zhong Zhong” and “Hua Hua” by nuclear transferring of somatic cells(體細(xì)胞)any cell in the organism other than reproductive cells.Tetra, a monkey born in 1999, is the worlds first cloned monkey, but it was done by usin
3、g a simpler method called embryo splitting(胚胎分割); but it could only generate four cloned offspring at a time and cannot be genetically changed to suit the experimental need.Cloning a monkey using somatic cells has been a worldclass challenge because it is a primate(靈長類) that shares its genetic makeu
4、p, and therefore all of its complexity, with humans.For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly and bad for the environment, and produces inaccurate results because each monkey might have different genes.By cloning monkey using somatic c
5、ells, we can massively cultivate large numbers of genetically identical offspring in a short amount of time, and we can even change their genes to suit our needs. This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.Sun Qiang, director
6、of the nonhuman primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.“Monkeys and humans are both primates, so they
7、are much closely related and testing on monkeys is supposed to be as effective as testing on humans，”he said. This is especially useful in testing drugs for neural (神經(jīng)的) diseases such as Parkinsons disease, metabolic syndrome (代謝綜合征) and immune system diseases, and tumors, he added.“This achievement
8、 will help China lead the world research in the international science projects related to neural mapping of primate brains，”he said. “However, bio labs from the United States, Japan, and European countries are also very capable, and they will quickly catch up with China after the monkey cloning tech
9、nology is made public，” Sun added.“This means we have to innovate continuously and work extra hard this year to stay ahead，” he said.本文是一篇科普類說明文。講述了中國在克隆技術(shù)上取得的成就中國成了第一個使用非生殖細(xì)胞克隆獼猴的國家。1Which of the following is the most important factor in cloning macaques named “Zhong Zhong” and “Hua Hua”？AReproduct
10、ive cells. BSomatic cells.CNeural mapping. DGenetic makeup.答案：B解析：細(xì)節(jié)理解題。根據(jù)文章第二段By December, the Institute of Neuroscience of the Chinese Academy of Sciences had created two clone macaques(獼猴) named “Zhong Zhong” and “Hua Hua” by nuclear transferring of somatic cells(體細(xì)胞)any cell in the organism othe

12、 makeup.答案：C解析：細(xì)節(jié)理解題。根據(jù)文章第四段Cloning a monkey using somatic cells has been a worldclass challenge because it is a primate(靈長類) that shares its genetic makeup, and therefore all of its complexity, with humans.可知，由于猴子是靈長類動物且與人類的基因相似，其復(fù)雜性也相似，所以用體細(xì)胞克隆猴子是一個世界級的挑戰(zhàn)。故選C。3What is the main idea of Paragraph 8?
13、AThe cure for neural diseases.BThe process of cloning monkeys.CThe significance of cloning monkeys.DThe close relations between monkeys and humans.答案：C解析：段落大意題。根據(jù)文章第八段內(nèi)容可知，此段主要說明克隆猴子的重要性，可以幫助人類測試藥物。故選C。4What can we infer from this passage?AMore effective medicine will be produced.BDrug trials on lab
14、 mice will be abandoned.CChina is the first country to have cloned monkeys.DChina will stay ahead of the world in cloning.答案：A解析：推理判斷題。根據(jù)文章第六段This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine. 可知，此舉可節(jié)省時間，降低試驗費用，并且可以使結(jié)果更精確，帶來更高效的藥物。由此
15、可以推測出，更多的有效藥物將被生產(chǎn)出來。故選A。.完形填空(2019廣東省湛江市高三調(diào)研)This morning I saw an old man.A few months ago he was _1_ cans and bottles from the recycle bins in my neighborhood.I was _2_ to see and saddened by the fact that he had to do this to _3_.I thought about putting bottles in a bag for him with a note attach
