Unit 21 Human BiologyPart 1 阅读完形组合准度练(建议用时40′)Ⅰ.阅读理解(共8小题；每小题2分，满分16分)A(2016·江西九校联考)Sleeping in a room with too much lighthas been linked to an increased risk of piling on the pounds，a study shows.A team at the Institute of Cancer Research inLondon found women had larger waistlines if their bedroom was“light enough to see across” at night.However， they caution there is not enough evidence to advise people to buy thicker curtains or turn off lights.The women were asked to rate the amount of light in their bedrooms at night as：Light enough to read.Light enough to see across the room，but not read.Light enough to see your hand in front of you，but not across the room.Too dark to see your hand or you wear a mask.Prof.Anthony Swerdlow told the BBC：“In th is very large group of people there is an association between reported light exposure at night and overweight and obesity.But there is not sufficient evidence to know if making your room darker would make any difference to your weight.There might be other explanations for the association，but the findings are intriguing enough to guarantee further scientific investigation.”The light is disrupting the body clock，which stems from our evolutionary past when we were active when it was light in the day and resting when it was dark at night.Light alters mood，physical strength and even the way we process food in a 24hour cycle.Artificial light is known to disrupt the body clock by delaying the production of the sleep hormone melatonin.Prof.DerkJan Dijk said there would be no harm in trying to make bedrooms darker.He told the BBC：“People in general are not aware of the light present in their bedroom.I think people should assess their bedroom and see how easy it would be to make it darker.” Street lights，some alarm clocks and standby lights on electrical equipment such as televisions could light a room，he said.“Overall this study points to the importance of darkness，” he concluded.1．The passage mainly tells us ．A．bright bedrooms link to obesityB．dark bedrooms link to obesityC．people should turn off lightsD．people should buy thicker curtains2．What does the underlined word “disrupt” (Paragraph 4) mean?A．Stop. B．Disturb.C．Improve. D．Recover.3．What might Paragraph 4 be used for?A．One possible explanation on disrupting body clock.B．One possible explanation on disrupting mood.C．One possible explanation on disrupting physical strength.D．One possible explanation on artificial light.4．What's Prof.DerkJan Dijk's attitude towards the dark room?A．Unclear. B．Doubtful.C．Negative. D．Favorable.【语篇解读】本文是一篇说明文。

________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________Science is developing so fast that it is beyond our imagination.Cloning is one of the most advanced technologies.Is it good or bad？Different people have different opinions.Some people are in favor of cloning technology.①They think the technology is of great benefit.Firstly，it can be used to produce valuable tissues and organs that could be used to cure diseases like cancer.Secondly，it can help those who are unable to have a baby but want a baby genetically related to themselves.Besides，it can help those who want to clone their dead relatives.However，a few people object to it.They believe cloning shows no respect for human life，and human life would no longer be unique.More seriously，it would create more diseases in the animal world and cause Earth’s population to increase fast.②In my opinion，although the technique is beneficial to mankind in many aspects，cloning human beings will be at the cost of the existence of mankind itself.根据①句临摹临摹1：许多人赞成这个计划，因为它有益于身体健康。
