7、some valuable advice：Look up at the stars and not down at your feet.Be curious.“However difficult life may seem，there is always something you can do and succeed at.”【语篇解读】本文是一篇人物介绍。主要介绍了Stephen Hawking这个人。虽然患有“渐冻人”症，但是他对人生的态度是积极的，并且取得了很多成就。1Why did Hawking think human should continue to explore spac
8、e?A.Because the earth became too weak to support us.BBecause human benefited by exploring the universe.CBecause many people suffered Lou Gehrigs disease.DBecause it is good for future generation to be weightless.A细节理解题。根据第一段中的“The 71yearold Hawking said he did not think humans would survive another
9、1，000 yearswithout escaping beyond our fragile planet”可知，他认为人类再过一千年如果不离开这个脆弱的星球就不会幸存下去。由此可推知，他认为人类应该继续探索宇宙是因为地球太脆弱了，不能供人类生存太久。2What do we know about Hawking?AHis bookA Brief History of Mine was a best seller.BHis lectureA Brief History of Time is about his life.CHawking got Lou Gehrigs disease when
10、he was in his twenties.DHawking has been in a depressed situation since he got the disease.C细节理解题。根据第一段中的“The 71yearold Hawking”以及第四段中的“Hawking was diagnosed(诊断)with Lou Gehrigs disease 50 year ago.”可知，他是在二十多岁时患上“渐冻人”症的。3What does the underlined word “longevity” in Paragraph 5 probably mean?AHis poo
11、r health.BHis long life.CHis mystery disease.DHis weakening muscle.B词义猜测题。根据第五段中的“Hawking has survived longer than most people with Lou Gehrigs disease”以及“But 50 years is unusual, to say the least”可知，“longevity”是指“长寿”。4What do you think the authors attitude to Stephen Hawking?ASympathetic.BSupportiv
12、e.CEnthusiastic. DRespectful.D推理判断题。本文描述了Hawking虽然患有“渐冻人”症，但是他对人生的态度是积极的，并且取得了很多成就。所以作者对他应该持敬佩的态度。BWhen the dog named Judy spotted the first sheep in her life，she did what comes naturally.The fouryearold dog set off racing after the sheep across several fields and，being a city animal，lost both her s
13、heep and her sense of direction.Then she ran along the edge of a cliff (悬崖) and fell 100 feet，bouncing off a rock into the sea.Her owner Mike Holden panicked and called the coastguard of Cornwall，who turned up in seconds.Six volunteers slid down the cliff with the help of a rope but gave up all hope
14、 of finding her alive after a 90minute search.Three days later，a hurricane hit the coast near Cornwall.Mr.Holden returned home from his holiday upset and convinced his pet was dead.He comforted himself with the thought she had died in the most beautiful part of the country.For the next two weeks，the
15、 Holdens were heartbroken.Then，one day，the phone rang and Steve Tregear，the coastguard of Cornwall，asked Holden if he would like his dog back.A birdwatcher，armed with a telescope，found the pet sitting desperately on a rock.While he sounded the alarm，a student from Leeds climbed down the cliff to col
16、lect Judy.The dog had initially been knocked unconscious (失去知觉的) but had survived by drinking water from a fresh stream at the base of the cliff.She may have fed on the body of a sheep which had also fallen over the edge.“The dog was very thin and hungry，” Steve Tregear said.“It was a very lucky dog
17、.She survived because of a plentiful supply of fresh water，” he added.It was，as Mr.Holden admitted，“a minor miracle (奇迹)”【语篇解读】本文是一篇记叙文。一只叫Judy的狗在追赶一只绵羊时坠落悬崖，后来此处又遭遇了飓风。主人寻找未果，伤心欲绝。没想到过了几周后，一个观鸟者却发现了这只死里逃生的狗，真是奇迹！5The dog Judy fell down the cliff when she was _Arescuing her owner Bcaught in a hurric
18、aneCblocked by a rock Drunning after a sheepD细节理解题。由文章第一段中的The fouryearold dog set off racing after the sheep across several fields and.Then she ran along the edge of a cliff and fell 100 feet.可知，小狗Judy是在追绵羊时坠落悬崖的。6Who spotted Judy after the accident?AA birdwatcher.BA student from Leeds.CSix volunte
19、ers.DThe coastguard of Cornwall.A细节理解题。由文章第五段中的A birdwatcher，armed with a telescope，found the pet sitting desperately on a rock.可知，后来Judy被一位观鸟者发现，故选A项。7What can we infer from the text?APeople like to travel with their pets.BJudy was taken to the fields for hunting.CLuck plays a vital role in Judys s
20、urvival.DHolden cared little where Judy was buried.C推理判断题。由文章最后三段可知，Judy坠落悬崖后靠喝悬崖下的小溪水活了下来，或许她靠吃与她一同坠落悬崖的那只绵羊的尸体而没有饿死，这只狗能幸存下来是一个奇迹。由此我们可以推断出，运气对于Judy能幸存下来起了很重要的作用，故C项正确。文章未提及人们喜欢带宠物旅行，故A项错误；文章也未提及Judy是被带到田里打猎，故B项错误；由文章第二、三、四段可知，Judy坠落悬崖后，她的主人悲痛欲绝，而不是不大关心，故D项错误。8Which of the following can be the bes
21、t title for the text?AMiracle of the Coastguard.BSurviving a Hurricane.CDangers in the Wild.DComing Back from the Dead.D标题归纳题。本文主要讲述一只叫Judy的狗在追赶一只绵羊时不幸坠落悬崖，但却死里逃生的故事，因此D项Coming Back from the Dead(死里逃生)最能概括本文大意。A项Miracle of the Coastguard(海岸警卫队的奇迹)、B项Surviving a Hurricane(在飓风中幸免于难)以及C项Dangers in the
22、Wild(野外的危险)均不能表达文章大意。CYour house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off.You can make your environment work for you instead of against you.Here are some ways to turn your home into part of your di

28、ut _Atheir home comfortsBtheir body shapeChouse buyingDhealthy dietsB细节理解题。根据文章首句Your house may have an effect on your figure.(你的房子可能会影响你的身材。)以及下面几个段落中提到的建议可知，本文是关于如何不变胖的，所以那些“关心自己体形的人”会觉得本文特别有帮助，故选B项。A项“家的舒适条件”；C项“购买房子”；D项“健康饮食”。10A home environment in blue can help people_Adigest food better Bredu
29、ce food intakeCburn more calories Dregain their appetitesB细节理解题。根据文章第三段中的.people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room.可知，人们在蓝色的房间里吃饭，要比在黄色或者红色的房间里少吃33%的食物，故B项“减少食物摄入量”正确。A项“更好地消化食物”，C项“消耗更多的卡路里”，D项“重新获得食欲”，都与颜色无关。11What are people advised to do at
30、mealtimes?AEat quickly.BPlay fast music.CUse smaller spoons.DTurn down the lights.C细节理解题。根据第四段中的People who eat slowly tend to consume about 70 fewer calories(卡路里)per meal than those who rush through their meals.可知吃饭越快吃得越多，排除A项“吃饭速度快”。根据第四段中的If you need some help slowing down，turn on relaxing music.可
31、知播放令人放松的音乐能让吃饭的速度减慢，排除B项“播放节奏快的音乐”。根据第二段首句Open the curtains and turn up the lights.可排除D项“把灯光调暗”。根据最后一段中的When we choose a large spoon over a smaller one，total intake(摄入)jumps by 14 percent.(选择大的汤匙要比用较小的汤匙多吃14%的食物。)可知，应使用较小的汤匙，故C项正确。12What can be a suitable title for the text?AIs Your House Making You
32、 Fat?BWays of Serving DinnerCEffects of SelfConsciousnessDIs Your Home Environment Relaxing?A标题归纳题。本文主要介绍了墙壁的颜色、房间的亮度、吃饭的速度以及吃饭时使用的器皿大小等都与一个人的身材有关。因此A项“你的房子正让你发胖吗？”最适合做文章标题。B项“提供正餐的方式”，C项“自我意识的作用”，D项“你家的环境令人放松吗？”，均与本文的主题不符。DElectric cars are dirty.In fact，not only are they dirty，they might even be d
33、irtier than their gasolinepowered cousins.People in California love to talk about “zeroemissions (排放) vehicles”，but people in California seem to be clueless about where electricity comes from.Power plants most all use fire to make it.Apart from the few people who have their roofs covered with solar
34、cells，we get our electricity from generators(发电机).Generators are fueled by somethingusually coal，oil，but also by heat generated in nuclear power plants.There are a few wind farms and geothermal(地热)plants as well，but by far we get electricity mainly by burning something.In other words，those “zeroemis
35、sions” cars are likely coalburning cars.Because the coal is burned somewhere else，it looks clean.It is not true.Its as if the California Greens are covering their eyes“If I cant see it，its not happening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy
36、 in it.But when you take that gas(or another fuel) and first use it to make electricity，you waste a nice part of that energy，mostly in the form of wasted heatat the generator，through the transmission lines，etc.A gallon of gas may drive your car 25 miles.But the electricity you get from that gallon o
37、f gas wont get you nearly as far，so electric cars burn more fuel than gasolinepowered ones.If our electricity came mostly from wind or geothermal，or solar，then an electric car truly would be clean.But for political，technical，and economic reasons，we dont use much of those energy sources.In addition，e
38、lectric cars batteries which are poisonous for a long time will eventually end up in a landfill.And finally，when cars are the polluters，the pollution is spread across all the roads.When its a power plant，though，all the junk is in one place.Nature is very good at cleaning up when things are not too c
39、oncentrated，but it takes a lot longer when all the garbage is in one spot.【语篇解读】很多人都认为电动汽车是非常环保的，加州人甚至普遍认为电动汽车是“零排放汽车”。事实确实如此吗？让我们从文章中寻找答案吧。13Whats the main idea of the passage?AElectric cars arent actually clean.BElectric cars are zeroemissions vehicles.CZeroemissions vehicles are popular.DGasoline
40、powered cars are more efficient.A主旨大意题。文章的首段就点明了主题，即电动汽车并非清洁、无污染，因为电能的产生很多时候也要消耗大量的能源，造成十分严重的污染，故答案为A项。14Which of the following words can replace “be clueless about” in Paragraph 2?ABe familiar with.BBe curious about.CFail to understand.DShow their interest in.C词义猜测题。联系第二段内容可知，加州人之所以认为电动汽车是零排放的环保车，主
41、要是因为他们没有理解或者忽视了电是从哪儿来的这个事实。故选“fail to understand”表示“没有理解”。15It can be inferred from the passage that _Aelectric cars batteries are poisonous for a long timeBnow electric cars are used more than their gasolinepowered cousinsCzeroemissions vehicles should be chosen to protect our environmentDelectric
42、cars are not clean in that we get electricity mainly by burning somethingD推理判断题。根据第二段的最后一句和第四段的第三句可知，获取电能如果是靠太阳能、地热或者风力等方式发电的话，电动汽车算是环保的，但是它们实际上现在主要还是靠烧煤、油等来发电，所以靠烧煤、油等发电的电动汽车并非真正意义上的环保车。.阅读填句(共5小题；每小题2.5分，满分12.5分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Dont you just love ice skating every winter?

62、tes by 45._ goods were transported between the East and the West.36exported考查过去分词。本句含有with复合结构，动词export和finely carved jade (翡翠) and medicinal herbs之间为逻辑上的被动关系，故应用过去分词形式，故填exported。37than考查固定搭配。每个商人在丝绸之路的某一段路上交易货物，而不是走整个丝绸之路。rather than意为“而不是”，为固定搭配。38buying考查现在分词。本句中buy和句子主语each merchant之间为逻辑上的主动关系，
63、故应用现在分词形式作伴随状语，故填buying。39carried考查时态。根据本文时态可知，本文讲述的是过去发生的事，因此本句应用一般过去时，故填carried。40on考查介词。have the greatest influence on表示“对影响最大”，故应填介词on。41eventually考查副词。这里是说它(佛教)最终成为中国的主要信仰。本句中应用副词修饰动词became，故填eventually“最终”。42protection考查名词。动词provided后应用名词作宾语，故填protection。43to rob考查不定式。attempt意为“试图，企图”，后跟不定式作宾语
64、，故填to rob。44a考查冠词。丝绸之路不是单纯的一条路，而是一整套路线，通过这些路线货物在东西方之间运输。此处表示泛指，a whole collection of意为“一整套”，故填冠词a。45which考查定语从句。分析句子结构可知，本句中“by 45._ goods were transported between the East and the West”为“介词关系代词”引导的定语从句，空处为关系词，指代先行词a whole collection of routes，故填which。.应用文写作(满分15分)最近，你校同学正在参加China Daily组织的一场讨论。谈论的主题
