课时分层作业(六)Ⅰ.阅读理解AThe earth is the only planet that scientists think has life.Why does the earth have life while the other planets don't？For one thing，the earth has just the right temperature.As the third planet from the sun，the earth seems to be just the right distance away.The planets which are closer to the sun are so hot because their surfaces are baked(炙烤) in the sun.The farthest planets are cold balls.When the earth developed—which scientists believe may have happened about 4 billion years ago—many gases covered the earth.The gases caused the earth to be hot.But something wonderful happened.The temperature was just right for thick clouds to form.It rained very hard for a very long time.This gave the earth its oceans.Water made it possible for plants to grow.The plants created oxygen in the atmosphere.Oxygen is the gas that humans and animals breathe.Another planet in the solar system seems to be something like the earth.That planet is Mars.Mars is smaller than the earth，and it is quite a bit cooler.But it is not too cold for humans.On some days，the temperatures are as low as a winter day in the northern United States.If you wore a special space suit，you could walk around on Mars.You would have to bring your own air to breathe，as the air on Mars is too thin to breathe.Mars has the largest volcano(火山) in the solar system.It is sixteen miles high.The highest volcano on the earth is five miles high.The most unexpected sight on Mars is dried­up river beds.Scientists believe that Mars was once much better than it is now.Does this mean there could have been living things on Mars？Scientists are not sure，but there has been no sign so far.【语篇导读】　本文是一篇说明文。文章先说明地球上存在生命的原因；又对比了火星与地球，说明火星与地球最相似。1．What is it on the earth that makes life possible?A．Temperature.B．Water.C．Oxygen.D．Temperature，water and oxygen.D　[细节理解题。根据第二段中“The temperature was just right for...Water made it possible for plants go grow...the gas that humans and animals breathe.”可知，温度、 水和氧气使地球上出现生命成为可能，故选D项。]2．What does the underlined phrase “the third planet” in the first paragraph refer to?A．The sun.　　 B．The moon.C．The earth. D．The Mars.C　[细节理解题。根据常识及画线词所在句后一分句均可知，距离太阳第三远的行星指的是地球，故选C项。]3．What should be the best title for the passage?A．Living Things on Our EarthB．The MoonC．Living Things on the MoonD．Mars is Most Like the EarthD　[标题归纳题。本文先讲述的是地球适合人类生存的原因，后面对比火星和地球在环境方面的异同之处，从气温、水、空气等方面展开，具体说明了火星与地球最相似，故选D项。]BWho is a genius? This question has greatly interested humankind for centuries.Let's state clearly: Einstein was a genius.His face is almost the international symbol for genius.But we want to go beyond one man and explore the nature of genius itself.Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?In the sciences and arts，those praised as geniuses were most often white men，of European origin.Perhaps this is not a surprise.It's said that history is written by the victors，and those victors set the standards for admission to the genius club.When contributions were made by geniuses outside the club—women，or people of a different color or belief—they were unacknowledged and rejected by others.A study recently published by Science found that as young as age six，girls are less likely than boys to say that members of their gender(性别) are “really，really smart.” Even worse，the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really，really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: absolutely not.Here's the good news.In a wired world with constant global communication，we're all positioned to see flashes of genius wherever they appear.And the more we look，the more we will see that social factors (因素) like gender，race，and class do not determine the appearance of genius.As a writer says，future geniuses come from those with “intelligence，creativity，perseverance (毅力)，and simple good fortune，who are able to change the world.”【语篇解读】　不论是在科学界还是艺术界，判断一个人是不是“天才”只有一个标准——“胜利者的标准”。然而这是一个极为不公平的判断标准，因为它将很大一部分人排除在“天才俱乐部”外。好消息是这种情况正在得到改善。4．What does the author think of victors' standards for joining the genius club?A．They're unfair.B．They're conservative.C．They're objective.D．They're strict.A　[推理判断题。根据第三段的“It's said that history is written by the victors，and those victors set the standards for admission to the genius club.When contributions were made by geniuses outside the club—women，or people of a different color or belief—they were unacknowledged and rejected by others.”可知，历史是由胜利者书写的，而这些胜利者也为“天才俱乐部”设定了标准。当“俱乐部”外的天才(即女性、不同肤色或信仰的人)做出贡献时，他们得不到认可，并会被其他人拒绝进入“天才俱乐部”。因此作者认为胜利者为“天才俱乐部”设定的准入标准是不公平的。故选A。]5．What can we infer about girls from the study in Science?A．They think themselves smart.B．They look up to great thinkers.C．They see gender differences earlier than boys.D．They are likely to be influenced by social beliefs.D　[推理判断题。根据第四段的“A study recently published by Science found that as young as age six，girls are less likely than boys to say that members of their gender(性别) are ‘really，really smart.’Even worse，the study found that girls act on that belief：Around age six they start to avoid activities said to be for children who are‘really，really smart.’”可知，该项研究发现，女孩会避免去做那些被认为是“特别特别聪明”的孩子才能做的事。由此可知，女孩可能受到社会观念的影响。故选D。]6．Why are more geniuses known to the public?A．Improved global communication.B．Less discrimination against women.C．Acceptance of victors' concepts.D．Changes in people's social positions.A　[细节理解题。根据第五段的“In a wired world with constant global communication，we're all positioned to see flashes of genius wherever they appear.”可知，有更多的天才被公众所知，其原因在于全球通信系统的改善。故选A。]7．What is the best title for the text?A．Geniuses Think AlikeB．Genius Takes Many FormsC．Genius and IntelligenceD．Genius and LuckB　[主旨大意题。根据文章最后一段中的“...social factors like gender，race，and class do not determine the appearance of genius.As a writer says，future geniuses come from those with‘intelligence，creativity，perseverance，and simple good fortune，who are able to change the world.’”可知，像性别、种族和阶层这样的社会因素并不能决定天才是什么样的。因此B项“天才有多种形式”最能概括本文的主旨。]Ⅱ.读后续写“Now，parents and students separate into two groups.You will be reunited at the end of the campus tour.”Groups of incoming freshmen happily left their parents upon hearing this announcement.I was less than thrilled about starting college，let alone leaving my mother's side to tour the campus with other freshmen；I felt a little anxious.We followed the senior tour guide.The other freshmen chatted and made casual introductions as I dragged behind.How could I have believed I was ready for this? After all，it had only been a few months since I left the hospital.I was feeling better for the first time in years.But college...?My thinking was interrupted by a sweet female voice，“Hi，I'm Jennifer.” “I'm Lauren，”I replied.“Where do you prefer to live? At home or on campus? ”she smiled.“I'm not sure，”I said.“You should live on campus！It will be a lot of fun! ”she said.Before I could reply，the tour guide announced it was time to create our schedules and select the courses we wanted to take.We crowded into the Student Activity Center.Three seniors handed out thick course bulletins (课程公告)and forms that needed to be filled out.All around me，the sounds of turning papers and writing sounded like those given by an alarm clock.Others seemed to be moving through the process quickly but I hadn't even opened my course catalog (目录)．“Focus，”I told myself.“Just read through the catalog and find the courses you like and a schedule that works.”Psychology A or B，Geology 101，English，History，sections 1，2，3...The list went on and on.I panicked and almost started to cry.How was I supposed to know how to complete it？I was just relearning how to live in the real world，and they wanted me to make a schedule.How I wished someone could help me.注意：1.续写词数应为150左右；2．请按如下格式作答。Soon，other freshmen were handing in their forms.                                                                          Then，I felt a warm hand on my shoulder.                                                                                                                                                   【参考范文】Soon，other freshmen were handing in their forms.Many of them rushed out to meet their parents.I couldn't breathe and was feeling anxious.My head was pounding.Moments later，I was crying.And several students started to stare at me.One of the seniors in charge walked over to my table.“What's the matter？” she asked impatiently.“I...I can't do this！” I said.“All you have to do is make your schedule，just like everybody else，” she said，clearly annoyed.Then，I felt a warm hand on my shoulder. I looked back and found Jennifer standing behind me.“Everything is alright，” she told the senior.“I'll help her.” The senior walked away.“What's wrong，sweetie？” Jennifer asked.Hearing Jennifer's kind words，I cried even harder，saying，“It's just too much！” Then Jennifer put her arm around me and said，“Let me instruct you.” She then guided me through the process step by step until I completed my schedule.Later，when saying goodbye，we made a promise to keep in touch.
