大家在备考英语四级的时候都是针对题型来进行备考的，这就导致大家忽略了语法的备考，但是语法却又是贯穿在每一个题型中的，那么语法应该如何备考呢?今天我们就为大家整理了大学英语四级备考之四级语法精解，希望能够帮助到大家。

　　非谓语动词等语法项目的测试特点和应对策略。

　　非谓语动词

　　近几年的语法测试中非谓语动词约占31.1%，平均每年近5道题，可谓是语法项目考查的重点，那么非谓语动词的考查都有哪些特点，解答时又应注意些什么呢?下面我和大家就一起来分析一下：

　　1、非谓语动词考查特点

　　1) 谓语动词与非谓语动词的判断

　　对谓语动词与非谓语动词区别的考查主要集中在独立主格结构，如：

　　All things ___ because of the snowstorm, many passengers could do nothing buttake the train.(1999.1)

　　A. had been canceled B. have been canceled

　　C. were canceled D. having been canceled

　　四个选项中有三个是谓语动词，只有D是非谓语动词，只要同学们能判断出这里是非谓语动词做状语，则不用考虑时态的问题，答案自明。

　　2) 谓语动词后不定式与动名词的选择

　　谓语动词后接不定式还是接动名词也是四级语法测试中的一个题眼。如：

　　① I don’t mind ____ the decision as long as it is not too late.

　　(2000.1)

　　A. you to delay making B. your delaying making

　　C. your delaying to make D. you delay to make

　　② Had I remembered ____ the windows, the thief would not have

　　got in.(1996.1)

　　A. to close B. closing

　　C. to have closed D. having closed

　　③ Your hair wants ______ . You’d better have it done tomorrow.

　　A. cut B. to cut C. cutting D. being cut(1997.6)

　　这类题涉及三个方面：

　　谓语动词后应该接不定式还是动名词?

　　即可接不定式又可接动名词时，结构和意思上有何差别?

　　不定式与动名词用主动形式还是用被动形式?

　　3) 做定语的非谓语动词的选择

　　从近几年的考查情况来看，对做定语的非谓语动词的考查有两种情况：

　　(1)对一般概念的考查，而不是固定结构中的非谓语动词做定语。如：

　　① The project ____ by the end of 2000, will expand the city’s

　　telephone network to cover 1,000,000 users.(1999.6)

　　A. accomplished B. being accomplished

　　C. to be accomplished D. having been accomplished

　　② If I correct someone, I will do it with so much good humor

　　and self-restraint as if I were the one ______.(1996.6)

　　A. to correct B. correcting

　　C. having been corrected D. being corrected

　　同学们只要掌握非谓语动词做定语的一般的规律,就可以判断①题答案为C，②题答案为D。

　　(2)对固定结构的考查，如：

　　① The professor could hardly find sufficient grounds _____ his

　　arguments in favor of the new theory.(2000.6)

　　A. to be based on B. to base on

　　C. which to base on D. on which to base

　　② The pressure _____ causes Americans to be energetic, but it

　　also puts them under a constant emotional strain.

　　A. to compete B. competing

　　C. to be competed D. having competed

　　①题为不定式做定语的固定形式，答案为D，②题为某些特定名词的定语结构，答案为A。在英语中有些名词，如动词变来的名词，形容词变来的名词，以及means,way, time, moment, reason等要求其后用不定式做定语，不定式没有体的变化。

　　语法是学习英语的基础，也是句子中间的比较重要的衔接语，如果语法不了解，说出的话，写出的文章都会怪怪的不够衔接，如果你面临四级考试，语法也是必备的，希望本篇文章的介绍能够帮助到大家。
