7、n Thursday.DOn Saturday.D细节理解题。根据Day 7：Saturday December 6段中提到“Not a cloud in the sky and its warm enough to sit outside (in a jacket)”可知，这一天不太冷，室外也挺暖和，这里备注写上是穿上了夹克，这天是第七天，12月6号，星期六，故选D。2What could stop Lizzie from leaving Stanley for Rothera?AStrong winds.BThick clouds.CMountains of ice.DLow temper
8、ature.A推理判断题。在Day 3：Tuesday December 2段中提到“People have to stay in Stanley for weeks while the pilots wait for good weather.”，可知，人们必须待在Stanley，因为飞行员在等一个好天气，前文又提到“Because Antarctica is the windiest place on earth”，由此推测应该是大风天气使得他们无法起飞，不能离开Stanley去Rothera，故选A。3How did Lizzie feel during her stay in the
9、Antarctic?AAfraid.BNervous.CAmazed.DBored.C推理判断题。在Day 4：Wednesday December 3段中提到“After waking up in the Antarctic for the first time today I can understand why everybody who comes here falls in love with the place.It is really beautiful.”可知，早上起来发现南极洲的风景实在是太棒了，一眼就爱上了，在最后一天的日记中也说“The most amazing thin
10、g about this place is how the scenery changes every day.”，由此可推断，Lizzie感觉南极很神奇，故选C。BMoving flight times from night to day could reduce air travels contributions to global warming, a new study suggests. Scheduling more daytime flights may reduce the influence of contrails(飞机凝迹) the visible lines of wh
11、ite steam that many planes leave behind them in the sky.The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.Nicola Stuber, first author of the study, suggests that contrails overall im
12、pact on climate change is almost as big as that of aircrafts carbon dioxide emissions (排放)over a hundredyear period. Aircraft are believed to be responsible for 2%3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. Howev
13、er，they also trap energy in the atmosphere and increase the warming effect.Stuber and other scientists believe that the effect of the contrails is big. “ On average, the greenhouse effect controls the effects of contrails，”said Stuber, a meteorologist at Englands University of Reading. “The warming
14、effect is far greater for contrails left by night flights，” Stuber added. “The cooling effect only happens during the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of nightflight is so large.”Most commercial airline traffic occ
15、urs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.【语篇解读】本文是一篇说明文。主要内容是将飞机飞行时间从晚上改到白天，即安排更多的日间航班可能会减少航空旅行对全球变暖的影响，并阐述了其原因。4How do contrails increase the greenhouse
16、 effect?AThey give off heat.BThey absorb daylight.CThey trap heat in the atmosphere.DThey reflect sunlight back into space.C细节理解题。根据第二段“.they contribute to the greenhouse effect by trapping heat in the atmosphere.”可知，飞机凝迹是通过它们在大气中吸收热量来增加温室效应的，故选C。5What does the underlined word “they” in Paragraph 3
17、refer to?ACarbon dioxide emissions.BContrails.CFlights.DThin clouds.B代词指代题。根据第三段最后两句介绍了飞机凝迹的两大作用：一是将阳光反射回太空、使地球降温，二是将能量困在大气层、加剧温室效应，再根据they所在的句子“However, they also trap energy in the atmosphere and increase the warming effect.”可知they指代的是“飞机凝迹”，故选B。6What did Stuber explain about the contrails in Para
18、graph 4?AWhat their function is.BHow they cool the Earth.CWhy they create big warming at night.DHow big their effect is.C推理判断题。通读第四段内容可知，飞机凝迹受温室效应的控制，降温效果只发生在太阳升起的白天，夜间的温室效应不再平衡，这就是夜间飞行留下的尾迹使温室效应更加严重的原因，Stuber是通过解释为什么它们会在晚上产生很大热量的原因来解释飞机凝迹的，故选C。7What can be a suitable title for the text?AAirlines Sh

24、azine for grandparents. “We now realize how important family is and how important it is to be near them, especially when youre raising children.”Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser
25、 to say no and visit frequently instead.Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.【语篇解读】本文是一篇关于人与社会问题的报道类夹叙夹议文。通过描述部分祖父母选择搬去和孩子们生活在一起，以便为孩子们提供帮助这件事，从而引发的更多人的选择与思考。8Why was Garzas move a success?AIt str
26、engthened her family ties.BIt improved her living conditions.CIt enabled her to make more friends.DIt helped her know more new places.A细节理解题。根据第一段最后一句“Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.”可知这次搬家给他们带来了
27、更紧密的家庭联系。故选A。9What was the reaction of the public to Mrs.Robinsons decision?A17% expressed their support for it.BFew people responded sympathetically.C83% believed it had a bad influence.DThe majority thought it was a trend.D细节理解题。根据第二段结尾处“.83 percent of the people said Mrs. Robinsons decision will
28、influence grandparents in the American family. Twothirds believe more families will follow the example of Obamas family.”可知83%的人认为Mrs. Robinson的决定会影响美国家庭，2/3的人相信更多家庭会效仿，所以“多数人认为这是一种趋势”。故选D。10What did Crosby say about people in the 1960s?AThey were unsure of themselves.BThey were eager to raise more
29、children.CThey wanted to live away from their parents.DThey had little respect for their grandparents.C推理判断题。根据第三段第一句“In the 1960s we were all a little wild and couldnt get away from home far enough or fast enough to prove we could do it on our own，”可知那时的人们一心希望离家越远越好、越快越好。故选C。11What does the author
30、suggest the grandparents do in the last paragraph?AMake decisions in the best interests of their own.BAsk their children to pay more visits to them.CSacrifice for their struggling children.DGet to know themselves better.A推理判断题。第四段首句“Moving is not for everyone.”已经说明“移居并非适合每一个人”，再结合下文“Having your gran
31、dchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.”可知“(祖父母)得知孩子们在异地艰苦的生活，是很难过的，但(祖父母)放弃自己熟悉的生活也许会更难过”，所以推断出作者建议“作选择时要慎重，要以自己最大的需求为衡量标准”。故选A。DBorn in 1918, in the little town of White Sulphur Springs, West Virginia, Katherine
32、Johnson was simply attracted by numbers. As a child, she counted everything.

67、。36personal句意：在西方国家，唯一敢告诉你胖的人是你的私人医生。此处用形容词personal(私人的)作定语修饰名词doctor。37talking介词短语as to(谈到、关于)，相当于介词about，介词后面用动名词(doing)作宾语。38is句意：中国人对外国人说“你很胖”是很常见的。此处缺少谓语，讲的是事实，用一般现在时，主语It是单数，主谓一致，谓语也用单数。故填is。39a此处泛指“一位中国朋友”，Chinese以辅音音素开头，应用不定冠词a表泛指。40why此处是定语从句，先行词是several reasons，在从句中作原因状语，应用关系副词why。41curios
68、ity句意：看到一个胖子几乎是一个罕见而有趣的事。由前面a可知，此处用名词作表语，curiosity可用作可数名词，表“罕见而有趣的事”。 42fewer句意：其次，私人问题较少。由全文语境可知，这里指相对美国来说，在中国，私人问题相对少一些，应用比较级。43and本句是“祈使句 and 陈述句”结构，前一分句表示一种假设/条件，相当于if条件状语从句，后一句表示一种结果/推论。故填and。44was playing此处缺少谓语，由Once和said可知，本句时态属于过去时间范畴，由句意可知，此处表“正在打篮球”，此处用过去进行时(was/were doing)，形成“was/were doi
69、ng.when.”结构，主语I是单数，谓语也用单数。45to stay句意：也许如果更多的美国人对别人的体重发表评论，那么这可能有助于提醒人们尽量保持健康。固定搭配try to do sth.(尽力做某事)，此处用动词不定式(to do)。符合句意。第三部分写作(共两节，满分40分)第一节(满分15分)假如你是李华，暑假在英国参加了你校组织的“中国学生文化交流周”活动，并住在Kelly家里。请你给在英国期间认识的新朋友Kelly写封感谢信，内容包括：1交流活动中的收获；2难忘在Kelly家的美好日子；3感谢她送你的英文词典。注意：1词数80左右；2可以适当增加细节， 以使行文连贯；3开头已给出

73、dents about airplanes. While all airplanes can fly, some are able to fly farther than others. This is because not all airplanes are built the same. For example, a fighter plane looks very different from a plane that people fly in when they want to go on a holiday. The teachers wondered how they coul
74、d make students understand this.Then, the science teacher, Mr. Moose, decided that the school should have a paper airplane contest. The students would produce paper airplane designs.They would stand in line on the playground behind the school. The students would take turns throwing their airplanes.
75、The student whose airplane went the farthest would win.When Mr. Moose announced the paper airplane contest to the students, they were very excited. A student named Paul, who was on the wrestling team，bragged (吹牛) to everyone else that his airplane would win. “I am the strongest，”Paut said. “So I wil
76、l be able to throw my airplane the farthest.”However, while Paul was saying this, another student, Brian, was thinking how he could win. Brian did not play any sports and was not very strong. But he loved airplanes and really wanted to win the contest.Brian realized what he had to do. He went to the
77、 store and bought a big stack of paper. When he got home, he took the paper into his backyard. He took a piece of paper and folded an airplane. It didnt go very far, so Brian took another sheet and folded another airplane and threw it. This airplane went a little farther. Brian kept folding differen
78、t kinds of airplanes and throwing them. Some went very far and some did not. Finally, when Brian had used all the paper, he walked up to the airplane that had flown the farthest and picked it up.注意：1续写的词数应为150左右；2请按如下格式作答。The next day was the contest._Brian won because he tried out many solutions to

He did this by testing out many different designs and comparing the results. When he found the design that worked bestthe paper airplane that flew the farthesthe used it. Because Brian tried a lot of designs，he was able to make up for his lack of strength and beat Paul.
