28、.我哥哥打算要结婚。What I would suggest is to start work at once.我的建议是立刻开始工作。误区警示:(1)动词不定式作表语一般表示具体的动作,特别是表示将来的动作。(2)主语是动词不定式(表条件),表语也是不定式(表结果)。(3)如果主语是以aim,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为中心的名词,或what引导的名词性从句,不定式作表语是对主语起补充说明的作用。(4)be about to do表主客观未实现的意图。(不与具体时间连用)(5)expect,int

31、型结构可以分为以下几种:It主句谓语部分连接词主语从句It is known to all that we love peace.众所周知,我们热爱和平。What主语及物动词谓语主句谓语部分What he said is right.他的话很对。Whoever/Whatever/Whichever主语从句主句谓语部分Whoever wants to go may go at once.不论谁想走,现在就可以走。注意:that从句作主语时,that无意义,但不能省略;但作宾语时that可省略。whether既可引导主语从句也可引导宾语从句,但if不可引导主语从句。(2)表语从句表语从句在复合句中
32、作主句的表语,其结构为“主语系动词连词(that/if/whether)/连接代词/连接副词“,引导表语从句的连接代词有who, whom, which, whose, what;连接副词有when, where, why, how等。This is why Einstein and his family left Europe for the USA in 1933.这就是爱因斯坦和他的家人于1933年离开欧洲去美国的原因。This is what he wants.这正是他想要的东西。(3)宾语从句在复合句中,作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句、表语从句的关联词大致
33、一样,在句中可以作谓语动词或介词及非谓语动词的宾语。用who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句,但句子要用陈述语序。I want to know what he has told you.我想知道他告诉你什么了。注意宾语从句中的时态呼应。当主句是现在时态,从句根据句子的自身情况,可使用不同时态;当主句是过去时态,从句要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象等时,从句仍用现在
34、时态。I know (that) he will study English next year.我知道他明年将学习英语。The teacher told us that Tom had left us for America.老师告诉我们汤姆已经离开我们去美国了。(4)同位语从句同位语从句主要用于对某一特定名词所表示的具体内容作进一步的解释或说明,从句与前面的名词之间是同位关系,这一名词在从句中不充当任何成分。同位语从句除了可以用that引导以外,还可以用whether, when, where或why引导。The news that he has come is true.他已来了的消息是
35、真的。I have no idea when they will come to visit China again.我不知道他们将何时再访问中国。注意:同位语从句中的that不作句子成分,但不能省略。活学巧练:(1)(2009潍坊12月检测)Later they discovered,_ was news to him,that Pamela was the headmasters daughter.Athat BwhichCwhat Dwho答案与解析:Cwhatthe thing that。若用which引导非限制性定语从句,which指代整个主句的意思,则which不能放在主句之前,或
36、插入到主句中间,只能放在主句之后。(2)(2007安徽)You can only be sure of _ you have at present; you cannot be sure of something _ you might get in the future.Athat; what Bwhat; /Cwhich; that D/; that答案:B(3)(2007上海)The traditional view is _ we sleep because our brain is “programmed” to make us do so.Awhen BwhyCwhether Dt
37、hat答案:D(4)I havent seen her_the time_she had the accident.Afor; that Bsince; whenCsince; as Dfor; when答案与解析:Bthe time是点时间,故不能用介词for;the time之后用when引导定语从句。(5)See the flags on top of the building? That was _ we did this morning.Awhen BwhichCwhere Dwhat答案:D考 题 演 练 1.(2009北京卷)At first he hated the new j

39、into调查,向里面看;look up查阅;抬头往上看;look through快速查看,浏览。由后面的and see if there are any obvious mistakes可知,空格处应表示“快速看一下”。3(2009江西卷)The fact has worried many scientists _ the earth is becoming warmer and warmer these years.A. what B. whichC. that D. though答案与解析:C分析句式结构可知此处缺少同位语从句的引导词,从句意义、结构均完整,所以选that。4(2009四川
40、卷)I like this house with a beautiful garden in front, but I dont have enough money to buy _.A. one B. itC. this D. that答案与解析:B代替前面提到的事物用it;one泛指一类中的任何一个。此时it代替前面的this house。5(2008江苏卷)They are quiet, arent they?Yes.

41、ng答案与解析:Dbe accustomed to习惯于,to为介词,后接名词或动名词;由句意可知表示否定意义,故选D项。6(2008重庆卷)People in Chongqing are proud of _ they have achieved in the past ten years.A. that B. whichC. what D. how答案与解析:Cwhat引导名词性从句,同时充当achieved的宾语。7(2008上海卷)As his best friend, I can make accurate guesses about _ he will do or think.A.
42、 what B. whichC. whom D. that答案与解析:Aguess about表示“猜测”,其后跟的应该是宾语从句。由于do or think为及物动词短语,故空格处既要引导宾语从句,又要在从句中作宾语使用,故可排除that;由于没有明确的范围,故可排除which;从句意看该处应指物而不指人,故可排除whom。8(2009安徽卷)We can never expect _ bluer sky unless we create _ less polluted world.A. a;a B. a;theC. the;a D. the;the答案与解析:A句意:如果我们不创造一个减少
43、环境污染的世界,我们永远不会期望拥有一个更蓝的天空。根据句意,“a bluer sky”“a less polluted world”为可数名词且表示泛指,所以都用不定冠词。9(2009湖北卷)His efforts to raise money for his program were _ because no one showed any intention to take a cent out of their pockets.A. in place B. in sightC. in effect D. in vain答案与解析:Din place在适当的位置;in sight在视力所及
44、范围之内;in effect实际上;in vain徒劳。由状语从句中的no one showed any intention可知,他筹钱的努力失败了。Module 5The Conquest of the Universe.单词拼写1. May we offer our deepest s_ on the death of your wife?2.

59、_cold_water,_and a big pinch of salt, on those hopes. “Liquid water is required by all species on Earth and weve assumed that water is the very least that would be necessary for life on Mars,” said study team member Nicholas J. Tosca, a Harvard University postdoctoral researcher. “However, to really
60、 assess Mars habitability we need to consider the properties of its water. Not all of Earths waters are able to support life, and the limits of terrestrial (地球上的) life are sharply defined by waters temperature, acidity and salinity.”Tosca and his team analyzed salt deposits in the 4billionyearold Ma
61、rtian rock investigated by Opportunity. The new analysis shows that the water that would have flowed across these ancient Martian rocks may have been very salty. “Our sense has been that while Mars is a bad environment for supporting life today, long ago it might have more closely resembled Earth,”
62、said Andrew HKnoll, also of Harvard and on the study team. “But this result suggests quite strongly that even as long as four billion years ago, the surface of Mars would have been challenging for life. No matter how far back we peer into Mars history, we may never see a point at which the planet re
63、ally looked like Earth.”The research was presented in February at the annual meeting of the American Association for the Advancement of Science in Boston. Halophiles, or organisms that can tolerate highsalinity waters, are known to exist in places on Earth,but they likely evolved from organisms that
64、 lived in purer waters, scientists think, making it unlikely that life would actually arise initially in extremely briny (多盐分的) waters.The high salinity, however, “doesnt rule out life forms of a type weve never encountered,” Knoll added, “but life that could originate and persist in such a salty se
65、tting would require biochemistry distinct from any known among even the most robust halophiles on Earth.” Knoll and Tosca also say the finding doesnt rule out the possibility that less salty waters once flowed on the planet. The best title of the passage is_. A. Mars Perhaps Too Salty for Life B. Sa
66、lt Water on Mars C. Life on Mars D. Research About Life on Mars答案与解析:A主旨大意题。本篇文章主要说明“机遇号”探测器在火星土壤中发现有水流过火星表面之后,一个研究组织发现这些水的含盐量很高,可能不适合生命的存在。所以选A项。 2.
