All week long, it seems, you sit _1_ at school while the sun shines outside. Then, as soon as the weekend comes, the sky _2_ gray. Theres rain in the forecast. In some ways, you may be right. Weekend weather_3_ from weekday weather in certain places, say researchers who studied more than 40 years of weather data _4_ the world. They focused on temperature differences between daytime highs and nighttime _5_. This difference measurement _6_ the diurnal temperature range, or DTR. Part of the study involved 660 weather _7_ in the continental United States. At more than 230 of these sites, _8_ average DTR for Saturday, Sunday, and Monday was different from the average DTR for Wednesday, Thursday, and Friday, the researchers _9_. The difference was small only several _10_ of a Celsius degreebut the pattern was striking enough to make the scientists take notice.In the _11_ US., temperature ranges were typically broader on weekends. In the Midwest, weekdays saw _12_ daily temperature variations. This sort of _13_ rise and fall doesnt line up with any natural cycles, the researchers say._14_， they blame human activities, possibly air pollution from those activities, _15_ these weather effects. For example, tiny particles in the air could affect the _16_ of cloud cover, _17_ would in turn affect daily temperatures. So, tiny windborne particles from California, generated on weekdays, might first affect weather _18_ to home in the southwest, _19_ later influence Midwestern weather. It looks like your weekend weather has a lot do with which way the wind _20_ and where it comes from.1. A. outside B. insideC. in D. out2. A. changes B. becomes C. turns D. looks3. A. differs B. different C. difference D. difficult4. A. from B. around C. from around D. around from5. A. highs B. tall C. small D. lows6. A. called B. is called C. calls D. calling7.

A. strikes B. blows C. beats D. hits答案与解析1Bwhile在此处表示对比，和后面的outside相呼应，故应该用inside。2C气候的变化要用turn(转化；变得)。change后面要加to或into。3A在这里应该用动词， differ from .“和不同”。4C考查重叠介词的用法。研究者们研究的天气变化数据来自世界各地，所以用from around the world。5D前面用的是daytime highs, 后面要用nighttime lows来进行呼应，所以选D项。6B习惯用法，“被叫做”要用be called, 因为前面的主语是单数，所以用is called。7A在这里说的是气象站，所以用station。而radio(收音机); room(房间); factors(因素)均不符合题意。8D考查冠词的用法。这里的the average DTR for Saturday, Sunday, and Monday是特指，与后面的the average DTR for Wednesday, Thursday, and Friday形成对比。9C研究人员发现这个现象是过去的事情，所以用一般过去时。10B考查分数的表达法，分母要用序数词，由于分子是several大于1，所以分母序数词要用复数加s，因此选B项。11B这里要选择一个形容词修饰U.S.，表示“西南方的”，故B项为正确答案。而southwest是名词，意为“西南方”； southwestward是形容词，意为“向西南方的”； southwestwards是副词，意为“向西南”。12Cweekdays和前面的weekend形成对比，是两者之间的比较，故要用比较级，所以选C项。13Aweekly每周一次的。14D和前面的情形形成对比，很明显要用instead来表示不干某事，而去做另外的事情。15Cblame sb. for sth.“因某事而责怪某人”。16Dthe amount of“的量”。17D这里是一个非限制性定语从句，要用which来指代前面整个句子的内容。18Aclose to .“离很近”，而closely是副词，意为“接近地”，不符合句意。19C和前面的first形成呼应，用then表示先后顺序。20B表示“刮风”，要用动词blow。.阅读理解To become a doctor in the United States, students usually attend four years of medical school after they complete college. Then these young doctors work in hospitals for several years to complete a training program called a residency.These medical residents provide hospitals with needed services in return for not much pay. They work under the supervision (管理) of medical professors and more experienced doctors. Medical residents treat patients. They carry out tests. They perform operations. They complete records. In hospitals with few nurses, residents also do work formerly done by nurses. Some medical residents work onehundred or more hours in a single week. They often work for more than thirtysix hours at a time before they can rest. Critics of this system say medical residents work too long and do not get enough rest. They say these young doctors may be too tired to perform their medical duties effectively. Now, the government will limit the number of hours of work that residents can work. Most doctors in training will be limited to eightyfour hours of work each week. They will have work periods of no more than twentyfour hours at one time. They will have ten hours of rest between work periods. Medical residents will have one day each week when they do not have to work. Any work they accept outside their hospitals will be limited. Experienced doctors and medical professors will closely supervise the residents to make sure they are not too tired to work.Many medical residents welcomed the work limits. Others,_however, said the new policy may interfere with patient care and their own medical education. 1If a firstyear college student in America wants to be a doctor, he has to wait for _.A. 4 years B. 8 years C. at least 10 years D. more than 20 years答案与解析C推理判断题。由第一段可知，美国的学生要想成为一名医生，在完成大学毕业(四年)后还要在医学院校学习四年，然后再经过好几年的实习期，故选C项。2.
