中考英語(yǔ)第三部分中招題型研究三 閱讀理解B 話題1 事物介紹（含解析）“Friends are the family you choose” Do you know why? A new study by Yale University and the University of California San Diego can give us some reasons.Scientists studied the genes(基因)of almost 2,000 people. Some of these people were friends, others were simply strangers. Scientists found that friends had more genes in mon than strangers. Pairs of friends had similar genes as people do with a distant relative(遠(yuǎn)親).This is about it’s of the human genome(人類(lèi)基因組). Although 1% may not sound like much to geneticists(遺傳學(xué)), it is an important number. “Most people don’t even know who their distant relatives are, yet we are somehow able to choose people who are like our relatives as friends” Nicholas Christakis, a social scientist at university told Live Science. This might be because similar genes make people visit similar places, or similar genes mean people will have similar skills. The most mon gene that friends have is the “olfactory” gene. It affects(影響)a person’s sense of smell. Imagine that you and someone else both like the smell of trees. You may often visit a park. Therefore, you may likely meet that other person and bee friends. As a result of the study, scientists set an interesting test called the “friendship source”. The test can tell whether two people could be friends by studying their genes. Do you want to know who will be your friends with the help of the test?1. According to the passage, how many people may not sound like much to geneticists among 2,000 people?A. 10. B. 20. C. 100. D. 200.2. According to the study, scientists found that friends had .A. more genes in mon than strangersB. fewer genes in mon than strangersC. fewer genes in mon than distant relativesD. more genes in mon than distant relatives3. What’s the meaning of “olfactory”?A. 聽(tīng)覺(jué)的 B. 視覺(jué)的 C. 嗅覺(jué)的 D. 觸覺(jué)的4. The test “friendship source” can tell whether two people could be friends by .A. visiting similar placesB. meeting similar peopleC. studying their genesD. having similar skills5. Where is the text most probably from?A. Advertisement.B. Newspaper.C. Novel.D. Note.【主旨大意】本文是一篇關(guān)于朋友的說(shuō)明文。

主要說(shuō)明了朋友之間是如何建立關(guān)系的在朋友之間有一些相似的基因，并且由這些基因?qū)е卤舜酥g形成了良好的友誼關(guān)系，從而成為很要好的朋友1. B【解析】數(shù)字計(jì)算題題干意為：根據(jù)文章，在xx人中有多少人跟遺傳學(xué)可能不符？根據(jù)第二段第一句“Scientists studied the genes(基因) of almost 2,000 people.” 和第三段最后一句“Although 1% may not sound like much to geneticists(遺傳學(xué))”可知，xx×1%=202. A【解析】細(xì)節(jié)理解題題干意為：根據(jù)研究，科學(xué)家們發(fā)現(xiàn)朋友 A項(xiàng)：相同的基因比陌生人更多；B項(xiàng)：相同的基因比陌生人更少；C項(xiàng)：相同的基因比遠(yuǎn)親更少；D項(xiàng)：相同的基因比遠(yuǎn)親更多根據(jù)短文第二段最后一句可知科學(xué)家們發(fā)現(xiàn)朋友的相同基因比陌生人更多3. C【解析】詞義猜測(cè)題題干意為：“olfactory”的意思是什么？根據(jù)olfactory所在句子后面的短文介紹中提到smell氣味，可推知是與嗅覺(jué)有關(guān)，故選C4. C【解析】細(xì)節(jié)理解題題干意為：“友誼分值”測(cè)試通過(guò) 能告訴兩個(gè)人是否能夠成為朋友。

A項(xiàng)：參觀相似的地方；B項(xiàng)：見(jiàn)相似的人；C項(xiàng)：研究他們的基因；D項(xiàng)：有相似的技能根據(jù)短文倒數(shù)第二段最后一句可知通過(guò)的方式是studying their genes5. B【解析】推理判斷題題干意為：這篇短文可能來(lái)自哪里？A項(xiàng)：廣告；B項(xiàng)：報(bào)紙；C項(xiàng)：小說(shuō)；D項(xiàng)：便條根據(jù)整個(gè)短文的內(nèi)容可以推斷出很可能來(lái)自于報(bào)紙。
