1、UNIT 1 SCIENCE AND SCIENTISTS课时分层作业(一).单词拼写根据汉语提示写出单词。1The evidence demonstrates how easily people can hold contradictory (相互矛盾的) beliefs.2Was his mother too severe (严厉) on him?3The driver of the crashed car received multiple (多样的) injuries.4We should transform our subjective world while transformin

2、g (改变) the objective world.5According to official statistics (统计数字)，the island had 37 people.6The traffic accidents in the city decreased (减少) last year.7They made substantial (重大的) changes to the arrangements.8The prime minister was always demanding active intervention (干涉) early on.9The police hav

3、e now narrowed down their list of suspects (犯罪嫌疑人)10He was not displeased at the way he handled (处理) the problem.阅读理解ABrian Greene, a professor of physics and mathematics at Columbia University, has created an online science education platform. He tries to “build a bridge” with things you know about

4、, and then “bring you across that bridge to the strange place of modern physics”Recently I had a chance to ask Greene about wormholes (a hole which some scientists think might exist, connecting parts of space and time that are not usually connected), time travel and other mysteries of the universe.

5、I asked him a milliondollar question：What if I went through a wormhole and prevented my parents from meeting? “Most of us believe that the universe makes sense，” Greene said. Although there are several interesting theories about time travel, he added, the laws of physics would probably prevent somet

6、hing so illogical from taking place. The good news is that the time paradox (悖论) is open for future physicists to solve.When asked how physics could become more exciting for kids, Greene said that books by Stephen Weinberg, Leonard Susskind, and other physicists, “make it a great time for people who

7、 want to learn about big ideas but arent yet ready，perhaps, to learn math. ”When I pointed out that some students still might find physics boring, Greene said that the key is to teach them about things that are strange. “The basic stuff is important，” Greene said. “But I think its really important t

8、o also describe the more modern ideas, things like black holes and the Big Bang. If kids have those ideas in mind, then at least some of them will be excited to learn all the details. ”Greene has followed Albert Einsteins lead in trying to solve the mysteries of the universe. Now he wants kids to do

9、 the same. As Greene said, physics is “not just a matter of solving problems in an exam”. Its about experimenting, showing an interest in strange phenomena (现象)and having fun!【语篇解读】本文是一篇说明文。物理学家Brian Greene希望更多的孩子能够对现代物理学感兴趣。1A milliondollar question is probably very AdirectBdifficultCpersonal Dlong

10、B细节理解题。根据第二段Greene对这个问题的解释以及他说需要未来的物理学家去解决可知，这个问题可能非常难。 2The books by Weinberg and Susskind Aare boring to readBare mainly about mathCare popular science booksDare only popular among kidsC推理判断题。根据第三段的“.books by.make it a great time for people who want to learn about big ideas but arent yet ready, pe

11、rhaps, to learn math”可知，Greene认为Weinberg和Susskind等物理学家写的书浅显易懂，适合大众阅读，故这些书属于科普读物。3According to Paragraph 4, which of the following does Greene agree with?AModern physics is a boring subject.BInterest plays an important role in studying.CIt is not necessary to learn all about physics.DIt is easy to de

12、scribe black holes and the Big Bang.B推理判断题。根据第四段可知，当作者指出一些学生觉得物理无聊时，Greene说重要的是向孩子们讲述一些稀奇古怪的事，并描述一些诸如黑洞和宇宙大爆炸的现代物理现象，如果孩子们知道了这些，他们就愿意了解更多详细的内容。因此他认为兴趣在学习过程中起着非常重要的作用。4In the last paragraph，Greene hopes that Akids can love science and physicsBkids can do well in physics examsCkids can have fun with e

13、xperimentsDkids can find more strange things in lifeA推理判断题。根据最后一段的“Greene has followed Albert Einsteins lead in trying to solve the mysteries of the universe.Now he wants kids to do the same.”可知，Greene希望孩子们可以像他一样对科学和物理感兴趣，去探索宇宙的奥秘。BSir John Gurdon, a British scientist, who won the Nobel Prize in Phy

14、siology or Medicine in 2012，said he had predicted at the time of his frog experiments that the successful cloning of a mammal would happen within 50 years, and that “maybe the same answer is appropriate” for the step to human cloning. Parents who lose children in accidents may be able to clone “copi

15、es” to replace them then.Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful. Cloning was regarded with extreme doubts when it was first developed but became widely ac

16、cepted after the birth of Louise Brown, the first “testtube baby”. He said，“When my first frog experiments were done, an American reporter asked how long it would be before these things could be done in mammals or humans. I said,Well, it could be anytime between 10 years and 100 yearshow about 50 ye

17、ars？ It turned out that it wasnt far off the mark as far as Dolly was concerned. Maybe the same answer is appropriate. ” Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be “copying what nature has already produced”The average v

18、ote on allowing parents of deceased children, who are no longer fertile (能生育的), to create another by using the mothers eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 percent in favor. The reasons for “no” are usually that the new children would feel th

19、ey are some sort of replacements for something.【语篇解读】本文是一篇说明文。诺贝尔生理学或医学奖得主、英国科学家约翰格登爵士称，那些在事故中失去子女的父母将能在未来50年内借助克隆技术，让他们的子女得到“重生”。5Sir John predicted the human cloning would be a reality in at most.Aabout 100 years Babout 60 yearsCabout 50 years Dabout 10 yearsC细节理解题。根据文章第一段可知，格登爵士表示，在未来50年内，那些在事故中失

20、去孩子的父母将有可能通过克隆技术得到孩子的“复制品”。6According to the text, which statement is NOT true?ALouise Brown is the first “testtube baby”BHuman cloning is still a controversial topic.CSir John is positive about the future of human cloning.DHuman cloning is creating something that didnt exist before.D细节理解题。根据第二段中的“a

21、fter the birth of Louise Brown，the firsttesttube baby”可排除A项；文章尾段说明赞成者占六成，故排除B项；根据第二段中格登爵士的话可知，他对克隆人充满了希望，故排除C项；根据第二段的尾句可知，D项表述不正确。7The underlined word “identical” probably means“ ”Asame Bspecial Cnew DclearA词义猜测题。根据画线词后的“twin”和“doctors would therefore simply be copying what nature has already produc

22、ed”可知，A项正确。8It can be inferred from the passage that Amost people cast doubt on Johns experimentsBhuman cloning is and will be only a dreamCfew children love to be cloned in the futureDhuman cloning may be realized somedayD推理判断题。根据文章第二段的第一句可知，虽然克隆人类的尝试将引起复杂的道德问题，但是生物学家声称如果克隆技术变得有医学价值，人们很快就会消除他们的担心。.

23、阅读七选五There is an old Spanish proverb which states, “Tomorrow is often the busiest day of the week. ” 1 Too many. But our dreams should not and cannot wait.Tomorrow is not promised.Nobody likes to talk about death, but the reality is that everybody will die some day. None of us know the day. 2 Dont g

24、o to your grave with unfinished dreams. Make the decision to go after every dream, big or small, right now.The world is waiting for your gift.The world is waiting for you. 3 Sure, other people may be able to sing, but theyll never be able to sing exactly like you. Sure, other people can write, but t

25、heyll never be able to write from the same point of view in which you write. 4 You can dream about writing a great novel, but its never going to happen unless you actually put your pen to paper. You can dream about finding a cure for cancer, but it will never happen unless you actually go to school

26、to become equipped with the necessary tools to find that cure.You cant let fear win.One of the biggest dream killers is fear. There are so many people who could have achieved amazing things if they werent afraid. Just think about all the things youve wanted to do, but allowed fear to convince you th

27、at you werent capable or good enough. 5 You can choose not to let fear stop you from achieving your dreams.ATherefore, today is all we have.BDreams dont work unless you do.CRemember that fear is just a choice.DYou were born into the world with a unique gift.EYou will be much happier if you go for yo

28、ur dreams.FThere are so many opportunities and people waiting for you.GHow many times have we put off our dreams until tomorrow?【语篇解读】本文是一篇议论文。人类因梦想而伟大，但梦想经不起等待。要实现你心中的梦想，那就即刻启程吧。1G根据该空后面的“Too many.”可知，这是对G项问题的回答。2A根据本段标题和本段内容可知，明天未可期，要实现梦想，当下就要行动，A项与前后语境相符。3D根据该空后面的内容可知，我们每个人都有独一无二的天赋，故选D。4B通读本段内容可知，千里之行，始于足下，梦想的实现，需要我们付出努力。5CC项中的“.fear is just a choice”与后面一句中的“choose not to let fear.”相呼应。- 5 -
