caught a coldcthey are starting to cough or have a feverdthey must be infected with permanent lung diseaseits that time of year when people need to lock their carsits not because there are a lot of criminals running around stealing carsrather，its because of good-hearted neighbors who want to share their harvestespecially with this years large crop，leaving a car unlocked in my neighborhood is an invitation for someone to fill it with zucchini（西葫芦）my sister，sharon，recently had a good year for tomatoesshe and her family had eaten and canned so many that they had begun to feel their skin turn slightly redthats when she decided it was time to share her blessingsshe started calling everyone she knewwhen that failed，she began asking everyone in the neighborhood，eventually finding a neighbor delighted to have the tomatoesfeel free to take whatever you want，sharon told herlater that day，sharon found that her garden had indeed been harvestedshe felt happy that she could help someone and that the food didnt go to wastea few days later，sharon answered the doorthere was the neighbor，holding a hot loaf of breadthe neighbor smiled pleasantly，i wanted to thank you for all of the tomatoes，and i have to admit that i took a few other things and hoped you wouldnt mindsharon couldnt think of anything else in her garden that had been worth harvesting and said sooh，but you did，the neighbor saidyou had some of the prettiest zucchini ive ever seensharon was confusedthey hadnt even planted any zucchinibut her neighbor insisted that there really were bright-green zucchini in her gardensharon felt curious and decided to go to see where the zucchini had grownthe two of them walked together into the backyardwhen the neighbor pointed at the long green vegetables，sharon smiledwell，actually，those are cucumbers（黄瓜）that we never harvested，because they got too big，soft and bitter for eatingthe neighbor looked at sharon，shock written all over her faceshe gulped（哽住）a few times，and then，smiling，held out the bread，part of a batch she had shared all over the neighborhoodi brought you a nice loaf of cucumber breadi hope you like it4why does the author warn people in the neighborhood to lock their cars？athey might be stolen by thieves at nightbthey might be moved away by the policectheir neighbors might fill them with their harvestdtheir neighbors might throw cucumbers into them5how did sharons friends react to the invitation to take her tomatoes？athey did not accept her kind offerbthey were all delighted to have the tomatoescthey said they would go when they were freedthey began to tell everyone they knew about it6what did the neighbor do in sharons garden？ashe only harvested some tomatoesbshe took some cucumbers mistakenlycshe took something with sharons helpdshe harvested a few zucchini by accident7we can infer that the neighbors bread would taste _ asoft and sweet bhard and sourcfunny and bitter dfragrant and deliciousmarch 21 has been declared world sleep day，a time to recognize and celebrate the value of sleepmany sleep experts hope it will be a wake-up callaccording to a 2016 poll（民意调查）by the national sleep foundation，nearly 4 in 5 americans dont get as much sleep as they should during the workweekon average，adults are thought to need at least eight hours of sleep a night，although some can manage with less and some wont do well without morebut the survey found that，on workdays，only 21% of americans actually get a full eight hours of sleep，and another 21% get less than sixto many of us，the thought of spending more time sleeping is，well，a big yawnon the other hand，the thought of being smarter，thinner，healthier and more cheerful has a certain appealand those are just a few of the advantages that can be ours if we consistently get enough sleep， researchers sayalso on the plus side： were likely to have better skin，better memories，better judgment，and，oh，yes，longer liveswhen you lose even one hour of sleep for any reason，it influences your performance the next day， says dralon avidan，director of the ucla sleep disorders centera study published last year found the same to be true even of children when kids aged 8 to 12 slept for just one hour less for four nights，they didnt function as well during the daybut sleeping has an image problemwe see napping or sleeping as lazy， says jennifer vriend，a clinical psychologist in ottawa，canada，and the leading author of the study with childrenwe put so much emphasis on diet，nutrition and exercisesleep is in the back seat in fact，she adds，no matter how much we work out，no matter how well we eat，we cant be in top physical shape unless we also get plenty of sleep8the underlined part in paragraph 1 means _ ato wake up the sleepers bto draw peoples attentioncto serve as a morning call dto declare the special day9from paragraph 3 we can infer that _ .athe thought of being healthier is not very attractivebsleeping has nothing to do with ones expectationscenough sleep is the guarantee of the appealing thingsdspending more time on sleeping is a waste of time10what jennifer vriend said in the last paragraph implies that _ apeople care little about sleeping bsleeping is not importantclazy people tend to sleep long dsleeping is only part of our life11what is the purpose of the passage？ato talk about peoples sleeping problemsbto provide an investigation result of sleepingcto stress the function of sleeping at nightdto raise the awareness of enough sleepingseveral years ago, masaru ibuka, chairman of sony, was at a company planning a meeting. suddenly he had a brilliant idea. he stopped the meeting and asked everyone present what would happen if sony removed the recording function and speaker and sold headphones with a tape player instead. almost everyone thought he was crazy. still, ibuka kept thinking about his idea and worked at improving it. the result, of course, turned out to be the wildly successful sony walkman.good ideas often start with a seemingly silly question. bill bowerman was making breakfast one day. as he stood there making waffles (华夫饼干)for his son, he wondered what would happen if he poured rubber into his waffle iron. later ,he tried it and the result looked something like the bottom of most sports shoes we see today. still, when he took this idea to several existing shoe companies, he was laughed at. in fact, every single company turned him down. though rather discouraged, bowerman insisted and went on to form his own company, making nike athletic shoes.sometimes good ideas grow out of frustration .when fred smith was a student at yale university, he had some paperwork that he needed to have delivered across the country the next day. smith was amazed to find out that overnight delivery was impossible. he sat for a long while, lost in thought. why couldnt there be a reliable overnight mail delivery service? he decided to design one. smith did just that and turned his design into a class project. his business professor gave him only a c for his efforts. however, smith was not through. he improved the idea in that class project and finally turned it into one of the first and most successful overnight mail service in the world fedex.we know that each of these ideas led to a very successful product or service that has changed the way many of us live. the best questions are usually open-ended and are often silly, children arent afraid to ask such questions, but adults frequently are. think how different the world might be if people never asked “ silly” questions!12which of the following is true according to the passage?asony walkman achieved great success with its recording function and speaker.bbill bowerman was experimenting with rubber for large shoe companies.cshoe companies rejected bill bowerman as they failed to see the potential of nike.dfred smith got the idea of an overnight mail service from his own experience.13what do the three persons mentioned in the passage have in common?athey were all determined about carrying out their ideas.bthey were good at answering other peoples silly questions.cthey started their own company after discussing with others.dthey had a very clear plan for their new ideas at the very start.14we can conclude from the passage that _.aasking others for their silly questions leads to inventionsblots of creative ideas usually end up as “silly” questionscadults usually ask more silly questions than childrendcrazy ideas sometimes contribute to great inventions15the passage is mainly developed by_.aanalyzing possible reasons bpresenting different opinionscproviding typical examples dlisting practical suggestion参考答案1 c2 d 3 a 【解析】【分析】本文是一篇新闻报道。在过去的几年里，中国政府一直在尝试所有的措施来减少污染。现在人们可以到处享受一个新鲜的环境。本文的两幅图取自北京周报网页“城市信息”栏目，来说明一些城市的污染情况。1推理判断题。根据graph : chinese national standard中01 to 50，medium pollution，red；51 to 300，high pollution ，purple.可推知，如果你的城市以红色或紫色为象征，那么你的城市的污染程度是中等或高的。故选c。推理判断题。根据graph 1: olympic cities air quality report中beijing，sep. 8 ，37和graph : chinese national standard中的0 to 50 ，very good，blue。由此推知，9月8日，北京空气质量的颜色象征是“蓝色”。故选d。3推理判断题。根据notes:中二氧化硫(so)作为酸。吸入会导致呼吸困难、咳嗽或喉咙痛，并可能导致永久性肺损伤。故选a。4 c 5 a 6 b 7 c 【解析】【分析】本文是一篇记叙文，介绍了邻居之间共享丰收果实时而出现的一个有趣的小插曲。4c细节理解题。根据第一段的第三句“rather，its because of the goodhearted neighbours who want to share their harvest”及第四句内容可知，好心的邻居会与他们共享丰收的果实，故选d项。5a细节理解题。根据文章第二段中的“she started calling everyone she knew.when that failed.”可知，她给认识的人打电话，结果失败了，故选a项。6b推理判断题。根据第五段中的“well，actually，those are cucumbers that we never harvested”可知，这位邻居错摘了莎伦家园子里的黄瓜，故选b项。7c推理判断题。根据文章第五段中的“because they got too big，soft and bitter for eating or canning”可知，邻居错把黄瓜当成了西葫芦，黄瓜面包的味道会有点怪，故选c项。8 b 9 c 10 a 11 d 【解析】【分析】作者通过一项调查说明如今的人们缺乏睡眠的现象十分严重，唤醒人们对于充足睡眠的意识。8推断题。由第一段第一句march 1 has been declared world sleep day，a time to recognize and celebrate the value of sleep可知，3月1日被宣布为世界睡眠日，是一个认识和赞美睡眠价值的日子，由此可以推之，很多睡眠专家希望可以通过这样一个宣传日来吸引更多人对于睡眠的关注，所以b项正确。a项唤醒睡眠者，c项用作一个叫醒电话，d项声明这个特殊的一天，均不合语境。故正确答案为b。9推断题。根据第三段第二、三句on the other hand，the thought of being smarter，thinner，healthier and more cheerful has a certain appealand those are just a few of the advantages that can be ours if we consistently get enough sleep，researchers say可知，变得更精明、更苗条、更健康和更愉快有十足的吸引力，而那些只是我们一直获得足够睡眠的众多优点中的几个，由此可推知，c项足够的睡眠是一些很有吸引力事情的保证符合文章说法，所以c项正确。a项，变得更加健康对我们来说是众多的优点之一，这是一个一般事实，而不是从文中推断而出，所以a项错误；b 项，睡眠和个人期望无关，由the thought of being smarter，thinner，healthier and more cheerful has a certain appeal可知，睡眠与个人期望有关，所以b项错误；d项，花更多的时间睡觉是浪费时间，与第三段的描述相悖，所以d项错误。故正确答案为c。10推断题。由最后一段第二、三、四句 jennifer vriend 说的话we see napping or sleeping as lazy，we put so much emphasis on diet，nutrition and exercisesleep is in the back seat可知，我们把打盹儿或睡觉看成懒惰，我们总是强调饮食、营养和锻炼，睡眠却抛在脑后，由此可以推知，a项人们很少在意睡眠符合 jennifer vriend 话中的意思，所以a项正确。b项，睡眠存在一个印象问题，是文章原话，作者通过引用 jennifer vriend 说的话来解释睡眠存在一个印象问题，而非jennifer vriend 的话中暗示（imply），所以b项错误；c项，懒人往往会睡懒觉，jennifer vriend 只是说人们会认为，而不是事实就是那样，c项无法推出，所以c项错误；d项，睡眠只是我们生命的一部分，jennifer vriend 说的是人们对于睡眠的印象问题和睡眠的重要性，d项无法推出，所以d项错误。所以正确答案为a。11主旨题。文章第一段通过 world sleep day 引出睡眠问题，第二段引用一项调查说明如今的人们缺乏睡眠的现象十分严重，第三段阐述足够的睡眠的好处，第四、五段说明缺乏睡眠的影响，最后一段通过引用 jennifer vriend 的话说明人们对于睡眠的刻板印象，再次强调足够睡眠的重要性，可见，文章的目的就是为了唤醒人们对于充
