1-1大学英语语法、重点分析、串讲、最新练习

大学英语语法--系动词与实意动词 在解答词汇和语法结构题时,可用以下几种方法: 1. 看准就选的直接选择法 "词汇与结构"考试的题型由题句和四个备选答案组成。在四个答案中,只有一个是正确的,其余三个都是干扰项。考生在答题时,首先应当运用直接选择法,也就是在做题时找出题句中与备选答案相关的词,利用语法规则--一般为固定搭配或习惯用法,直接选出答案。一旦看准,就不必再往下看,这样既能节省时间,又能提高正确率。 例:1994年1月四级第45题: The police set a________ to catch the thieves. a. plan b. device c. trap d. trick 本句意思为:“警察设了一个陷阱来抓小偷。”“设圈套”的一般表达“set a trap”,是一个习惯搭配。 例:1994年1月四级第62题: Medical research has shown that the widespread use of cigarettes contributes________the increase of cancers. a. towards b. for c. with d. to 本句涉及固定词组contribute to, 意为“有助于”“促成”,填入空格中,题句语义连贯。 例:1999年6月四级第51题 Tony is very disappointed________the results of the exam。 A) for B) toward C) on D) with 本题考查词组的搭配,be disappointed with意思是“对……失望”,大部分考生对此词组都很熟悉。 2. 逐个排除法 在答题时,如果不能从四个备选答案中根据词组的固定搭配或习惯用法直接选出答案的话,就应该从题的句子结构和上下文意思两方面加以考虑,通过对语义、语法、逻辑的分析,或通过词汇、语法、辨析来逐个排除,确定三项都有错误,以便推论不知意思的项为正确答案。 例:1999年月四级第50题 Being a pop star can be quite a hard life,________with a lot of travelling heavy schedules. A) as to B) in relation to C) owing to D) with regard to 选项C) owing to 的意思是“由于”。符合题意“由于时间很紧……”。选项A) as to 意思是“至于,关于”。选项B) in relation to 意思是“关于,涉及,与……相比”。而选项D) with regard to 意思是“关于”。 A)、B) 、D)三个选项在意思上都不符合题意。 例:1995年6月四级第48题 While people may refer to television for up-to-the-minute news, it is unlikely that television________the newspaper completely. A) replaced B) have replaced C) replace D) will replace 本句的意思是“虽然人们可以从电视了解最新消息,但电视不大可能完全取代报纸”。句中unlikely表示说话人认为某事将来不大可能发生,或者认为不大可能成为事实,因此应当用陈述语气将来时。选项A) replaced 为一般过去时,从全句意思来看,显然不合适。应予以排除。选项B)have replace 违反了主谓语一致的原则,应予以排除。选项C) replace与单数主语television在数上不一致,也违反了主谓语一致原则,应予以排除。因此,本题答案为D) will replace。
