从历年考试的语法结构部分的试题来看，重点主要涵盖以下语法点：动词的时态、语态， 情态动词，虚拟语气，非谓语动词及各种从句。下面分别进行讲解。
从历年的试题来看，动词时态都占有一定比例。因此掌握好时态的用法对考生来说十分重要。除掌握常用时态的一般用法以外，某些时态的特殊用法及某些特定句型中时态的用法要特别引起我们的注意。
一、考试重点：
1、一般现在时可以代替将来时，用于时间和条件状语从句中。
（1）Return the book immediately to the library as soon as you _____with it.
A. finish
B. are finished
C. have finished
D. are finishing
（答案：A。94年51题）
（2）Please be sure to telephone me the next time you _____.
A. will come
B would come
C. shall come
D. come
(答案：D。93年49题)
2、在“This is the first time…”结构中，后面的从句用现在完成时。句子开头也可以用it代替this
例：This is the first time that I have met Jane.
3、在“It/This is +形容词最高级+名词后面的从句中，用现在完成时。”
例：This is one of the best books _____ on the subject.
A. that have ever been written
B. which have ever been written
C. that has ever been written
D. whatever have been written
（答案为A。）（2000年45题）
4、在“It is/has been +时间段+since…后边用过去时。”
例：It has been twenty years since I left my hometown.
5、在“no sooner…than”和“hardly… when…”结构中，主句部分用过去完成时，从句部分用过去时。
（1）I had no sooner returned than he called.
（2）We had hardly begun when we were told to stop.
6、在“It is (high) time后边的从句中用过去时。”
例：It is time that we had a rest.
二、解题技巧：
1、注意寻找题中所包含的时间状语，从中判断出正确时态的使用。
例：I suppose that when I come back in ten year’s time all these old houses _____ pulled down.
A. would have been
B. would be
C. will be
D. will have been
（此句中，when引出的时间状语表示将来的时间，应用将来时态的动词形式。因此可以排除A和B项。那么是用一般将来时还是将来完成时呢？根据本句的意思，说话人想要表达的是十年后回来已经发生的情况，因此应当选择D。）
2、当题句中没有明显的时间状语时，应注意句子中已出现的时态，以此作为参照物。
例：Neither of the young men who had applied for a position in the university _____.
A. has been accepted
B. have been accepted
C. was accepted
D. were accepted
（读完句子我们发现定语从句中使用的是过去完成时，显然这主句要表达的是从句动作之后的动作，应当用过去时态。因此答案是C。）
