题型组合训练.单项填空1.She could have been in time for the interview, but her flight.A.was delayingB.had been delayedC.has delayedD.was delayed答案D句意:她本可以及时赶上面试的,但是她的航班延误了。根据句中的could have been可知,这是对过去情况的假设,因此but后的分句陈述的是过去的情况,应用一般过去时。2.Mr. Zhang once taught in a remote village in Anhui Province as a volunteer, which was only on foot.A.acceptableB.accessibleC.availableD.appropriate答案B句意:张先生曾经作为一名志愿者在安徽省的一个偏远山村支教,那里只有步行才能到达。acceptable可接受的;accessible可进入的,易接近的;available可用的,可得到的;appropriate合适的,恰当的。3.I looked up and noticed a snakeits way up the tree to catch its breakfast.A.to windB.windC.windingD.wound答案C句意:我抬起头,看到一条蛇正在蜿蜒着向树上爬行去捕食早餐。本题考查非谓语动词。此处结构为notice+宾语+宾语补足语。分析句子可知,空格处动作与宾语之间为逻辑上的主动关系,wound为动词的过去分词形式,排除D项;省去to的不定式结构作notice的宾补,表示动作的全过程,与句意不符,排除B项;现在分词作notice的宾补表示动作正在发生,符合语境。故选C项。4.We have been told that under no circumstancesthe telephone in the office for personal affairs.A.may we useB.we may ringC.we could borrowD.did we answer答案A句意:我们已被告知,无论如何我们都不能使用办公室的电话办私事。under no circumstances决不,无论如何都不,当位于句首时,句子要部分倒装。answer接听,不符合句意。5.After the professor, the project, made a comment on the report, the media focused on it.A.was opposed to carry outB.opposed to carry outC.oppose carrying outD.opposed to carrying out答案Dbe opposed to.“反对”,to 为介词,后跟名词、代词或动名词作宾语,故选D项。6.All the passengers, according to the new regulation, before boarding the subway.A.will inspectB.are to be inspected C.are going to inspect D.are about to be inspected答案B句意:根据新的规定,所有乘客在上地铁之前都得被检查。本题结合时态考查动词的语态。all the passengers与inspect之间存在被动关系,排除A、C两项。be about to do sth.即将做某事,不符合语境,be to do sth.可以表示命令或规定,符合语境,故选B项。7.I wont any more of your nonsensenow get down to work!A.get rid ofB.put up withC.live up toD.get along with答案B句意:我不会再容忍你们胡说了现在开始工作!put up with容忍,符合句意。get rid of摆脱;live up to不辜负,达到;get along with与和睦相处。8.Guess what!I came across my primary school teacher this morning, I have lost touch for almost 20 years.A.of whichB.whenC.with whomD.who答案C句意:你猜怎么着!今天早上我碰见我的小学老师了,我和他失去联系差不多20年了。本空需用关系代词引导定语从句,关系代词在从句中作宾语,且用来指人,用whom或who;但此处还需用介词with与从句的动词构成短语lose touch with sb.“与某人失去联系”,故选C项。9.He is afraid to face the difficulty he thinks hell have the driving test tomorrow, and he finds it difficult the worries.A.passed;got rid ofB.passing;to get rid ofC.to pass;getting rid ofD.passing;in getting rid of答案B句意:他不敢面对他认为在明天驾照考试时将要遇到的困难,并且他发现很难摆脱这种担忧。the difficulty后面是定语从句,定语从句中包含一个宾语从句,此处是have difficulty(in)doing sth.结构,故第一空填passing;分析句子结构可知,第二空前的it为形式宾语,不定式作真正的宾语,故B项正确。10.Fearing that most of the citizens voted him, he a smile.A.for;performedB.for;managedC.against;controlledD.against;wore答案D句意:担心大多数市民投他的反对票,他脸上流露出微笑。vote against投票反对;wear面带,呈现(某种神态)。11.Due to the unreasonable individual income,the gap between the rich and the poor has become an outstanding issue.A.contributionB.associationC.accommodationD.distribution答案D句意:由于个人收入的不合理分配,贫富之间的差距已经成为一个突出的问题。考查名词词义辨析。distribution分配,分布;contribution贡献;association协会,联系;accommodation住处。12.At the lecture last Sunday, Mr Pauls humor was such as all present burst into laughter.A.to makeB.makingC.madeD.being made答案A句意:在上周日的讲座上,保罗先生是如此幽默,以至于使所有在场的人都大笑起来。such as to do意为 “如此以至于”。13.Jack came from a poor family, so his parents had to a lot to pay for his schooling.A.accuseB.qualifyC.purchaseD.sacrifice答案D句意:杰克来自一个贫困家庭,因此他的父母为供他上学牺牲了很多。sacrifice牺牲,符合句意。accuse指责,控告;qualify使具有资格,使合格;purchase购买。14.The experiment shows that proper amounts of exercise, ifregularly, can improve our health.A.carry outB.carrying outC.carried outD.to carry out答案C句意:实验表明,适量的锻炼,如果有规律地进行的话,能提升我们的健康。此处为条件状语从句的省略,补充完整为:if proper amounts of exercise is carried out regularly,省去和主句一致的主语和be动词后,保留过去分词短语。15.We have very strict quality control and anything imperfect is ,so customers feel secure about our products.A.deniedB.rejectedC.desertedD.refused答案B句意:我们严把质量关,任何有瑕疵的产品都被退回,因此消费者对我们的产品大可放心。reject “(因质量不好而)不用,不出售”,符合句意。deny否认;desert抛弃,遗弃;refuse拒绝。.阅读理解Humans are working to find ways of capturing extra carbon dioxide (CO2) from the atmosphere and keeping it in the Earth. But nature has its own methods for the removal and long-term storage of carbon, including the worlds river systems, which transport decaying organic material and eroded (侵蚀) rock from land to the ocean.In a study published on May 14 in the journal Nature, scientists calculated the first direct estimate of how much and in what form organic carbon is exported to the ocean by rivers. The scientists amassed data on sediment (沉积物) flowing out of 43 river systems all over the world. From these river sediment flow measurements, the research team estimated that the worlds rivers annually transport 200 million tons of carbon to the ocean. The total equals about 0.02 percent of the total mass of carbon in the atmosphere. That may not seem like a lot, but over 1,000 to 10,000 years, it continues to add up to significant amounts of carbon (20 and 200 percent) removed from the atmosphere.When organic material decays, a small part of it ends up in rivers. They carry it out to sea, where some settles to the seafloor and is buried and disconnected from the atmosphere for millions of years and eventually makes its way back to the surface in the form of rocks. At the same time, rivers also erode carbon-containing rocks into particles. This process sends the previously locked-up carbon back into the atmosphere. Until now, scientists had no way to distinguish how much of the carbon washed away by rivers comes from either the organic or rocky sources. To solve this dilemma, the scientists found a novel way to distinguish for the first time the sources of that carbon. They analyzed the amounts of carbon-14, a radioactive isotope (同位素), in the river particles. Carbon-14 is present only in material that came from living things, but not rocks. Taking away the portion of particles that did not contain carbon-14, the scientists calculated the percentage that came from organic material: about 80 percent. They also discovered that the more erosion occurs along the river, the more carbon it transfers to the sea and disconnects from the air.“The atmosphere is a small reservoir of carbon compared to rocks, soils, the biosphere, and the ocean,” the scientists wrote in Nature. “As such, its size is sensitive to small imbalances in the exchange with and between these larger reservoirs.”The new study gives scientists a firmer handle on measuring the role of global rivers in the global carbon cycle and strengthens their ability to predict how riverine carbon export may shift as Earths climate change.1.According to the study, organic carbon .A.makes up 2% of the total carbon in the airB.is buried under the seafloor foreverC.can only be found in living thingsD.will come back to the air eventually2.The underlined word “novel” in Paragraph 4 is closest in meaning to .A.newB.normalC.complicatedD.precise3.It can be inferred from the passage that .A.before the study scientists didnt know that rivers transport carbon to the oceanB.rivers dont have much influence on controlling the carbon in the airC.rivers running through thick forests transport less carbon to the oceanD.the largest amount of carbon is stored in the atmosphere答案语篇解读这是一篇科普说明文,介绍了河流如何调节全球的碳循环。1.D细节理解题。根据第三段最后两句“At the same time, rivers also erode carbon-containing rocks into particles. This process sends the previously locked-up carbon back into the atmosphere.”可知河流侵蚀含碳的石头,石头变成颗粒,最终石头中的碳返回到大气中。2.A猜测词义题。根据该词后面的“for the first time”可以推测出词义。3.C推理判断题。根据第四段最后一句“They also discovered that the more erosion occurs along the river, the more carbon it transfers to the sea and disconnects from the air.”可以得知在侵蚀严重的地区,河流会把更多的碳送进海洋。在茂密的森林地区,河流的侵蚀作用比较小,所以进入海洋的碳也较少。.书面表达请阅读下列材料,并按要求用英语写一篇150词左右的文章。材料1:各国对迟到时间容忍度的情况调查(单位:分钟)材料2:There are few habits as annoying as someone makes us wait. However, some punctually-challenged people have no intention of offending anyone. They still want to keep friends, family and bosses happy. They are often painfully aware and ashamed of the damage their lateness could do to their relationships, reputations, careers and finances.Johnson, a doctor in New York, says his reputation for being unpunctual can sometimes be attributed to a misunderstanding of opinion. “A friend will ask me to come over, and hell say come anytime after seven. But if I do turn up at eight or later, he will be annoyed.”Joanna, a teacher in London, for whom the most distressing thing is writing school reports, never makes the deadline for herself. “I always spend weeks carefully considering everything about the reports,” she says, “just for fear that any error arises.”写作内容1.用约30个单词为以上材料撰写概要;2.用约120个单词发表你的观点,内容包括:(1)迟到带来的不良影响(至少两点);(2)给Johnson和Joanna提出你的建议,至少两条。写作要求1.写作过程中不能直接引用原文语句;2.作文中不能出现真实姓名和学校名称;3.不必写标题。评分标
