Anna was reading a piece of science fiction, completely _____ to the outside world.A. having been lost B. to be lost C. losing D. lost答案是D译:安娜在看一篇科幻小说,完全感觉不到外部世界。析:考查非谓语动词作状语。其逻辑主语是主句主语即安娜。一般说sb. is/was lost in sth. 说某人迷失在。。。中。 并不是说sb. loses sth. (某人丢了某物),所以排除C。是同时发生的伴随情况而非之前发生的动作或存在的情况,排除A。 不定式作状语表示未来和目的,B不妥。排除。1991年考研英语真题 19 . Anna was reading a piece of science fiction, completely _ to the outside world. A. being lost B. having lost C. losing D. lost 此题有所改动。补充:be lost to和be lost in的区别:be lost to: a. 感觉不到例句与用法: 1). My son was lost to me when he married. 我儿子结婚以后,就不再听我的了。 2). The opportunity was lost to them. 他们已失去了这个机会。 be lost in: a. 忘乎所以(迷路)1). Much of the goodness in food may be lost in cooking. 食物在烹调中可能失去许多养分. 2). The old man was lost in thought and did not hear us come in. 这个老人凝神沉思,没有听见我们进来。 2. _____ what to do with the urgent business, he stayed awake all night.A. Leaving wondering B. Being left wondering C. Being left to wonderD. Left wondering答案是D,为何C不行?答:考查非谓语动词短语作状语,放在主句的前面。其逻辑主语是主句的主语He,“他”和leave是被动关系,排除A。 leave sb. wondering ..., 没有leave sb. to do sth.的用法,排除C。 being left和left都表示被动。前者表示“正在进行的动作,与主句谓语动作同时发生的动作”,后者强调被动,不表示进行。而leave sb. doing sth. 中的leave无进行意味,所以选D译:不好译,因为人工造句,不知道是谁或什么事leave him wondering ...其实这句话改为:Wondering ..., he....就可以了:由于不知道如何处理这个紧迫的事务,他彻夜未眠3. He was suddenly _____ with a strange illness when he was about to finish his work.A. seized B.caught C. infect D. controlled答案是A答:此题考词汇。C应用过去分词infected ,且这不是一个突然的动作。D be controlled by sth.介词搭配首先不当。B。 be caught in sth. 也是介词搭配出了问题。A 的用法其实不熟悉。排除法剩下的是它。确定它正确还需要查词典,找例句。译:就在他快要完工时,突然得了一种怪病。评:好象题句写反了,一般句型是:sb. was about to do sth. when suddenly sth. unexpected happened.本题有待进一步考证。4. The earthquake and the heavy losses _____ contributed to disabled the family to afford his ecation.A. that B. it C. what D. which答案是B,这题完全没看懂。。答:此题句确实不好懂。主句结构是:A and B (定语从句) disabled sb. to do sth.译:这场地震及其引起的惨重损失使家里不能供他上学。析:it contributed to 是省略了关系代词的定语从句。it指代这场地震。定语从句还原就是:It (=the earthquake contributed to the heavy losses) 省略了的关系代词that指代先行词the heavy losses,在从句中作contributed to的宾语 contributed to相当于led to/resulted in,导致。5. -Do you smoke? -No, I don't. But I used to. It's two years since I ______ .A. smoked B. didn't smoke C. have smoked D. began to smoke答案是A, 为何不是完成时?答:最后一个是句型:It is (= has been) + some time since sth. happened. 自从某事发生以来,时间已经有多久了。而since后一般短暂性动词,用延续性动词很少的,翻译时要反过来(有的语法书上有所论及,其实是人工造句,不要全信,有时间别贴讨论)译:你抽烟吗? 不。我不抽。但我以前曾经抽过。自从我戒烟以来,到现在已经有两年了。如果你问:为什么不是B,为什么不是D,为什么since I smoked 要译为自从我戒烟以来,不是自从我抽烟以来,就又有很多可讲了。你另贴问,另贴回吧。对哦,为何这题译为自从我戒烟以来??麻烦解释,分数后面追加给你。谢谢。答:这是很老套的英语语法点。现在避免这么出这样的题了。我们知道,since 一个时间点,表示自从这个时点点以来到现在为止,主句用现在完成时,主句动作用延续性动词。这个时间点是相对的。如:since six o'clock, since last week/ month/ year, since 1997. 这些介词since 后面的时间点,有钟点,有周,有月甚至是年!但相对于主句的延续而言,只是一个点。如:It is ( has been) 14 years since 1997. 从为连词,since 后面可以跟一个从句:since sth. happened,这个happened一般都是短暂性动词,用来表示一个时间点:It is(=has been) 14 years since Hongkong returned to China.1997年尽管有365天,但是,在时间轴上,我们将它画成一个点!1997 Now--+-------------------------------------------------------------> time ||待续1。貌似是固定搭配 lost to the world,因投入没有注意到周围的事2.Being left不恰当,根据语态是left sth、sb doing表一种状态。被留下内来思考,此处容强调的是wonder的过程,且leave是一个短暂性动词,不能这么用3也是搭配问题,caught 用作被动常接by/in,infect其实可以同with搭配,但没用被动态,D你应该不会考虑吧?4意思好想知道,但我也不会,真抱歉。意思:地震和造成的严重损失导致他们家付不起他的学费5。这个我们竞赛班讲过,是特殊句式来的,有点抽象。只能再给你一个例句:She used to live here,but she has left.It's 5 years since she live here.直接就可以用来表示她走了5年,我觉得还是去问老师比较好,这个句型很有用希望帮得上忙
