初级英语语法重点、考点与难点(11)

8. It’s time后的从句谓语用何形式

It’s time the child ______ to bed.

A. goes                    B. going                   C. went                    D. to go

此题应选C。关于It’s time＋that从句, 注意以下几点：

1. 从句谓语通常用过去时态或should＋动词原形：

It’s time we started. 我们该动身了。

It is time that you left here. 你该离开这儿了。

It’s time you studied hard. 你该努力学习了。

有时也用should+动词原形或用过去进行时, 有时甚至将should省略(即只用动词原形, 为非正式的美国口语)：

我们该走了。

正：It is time we left. (常见)

正：It is time we should leave. (可用)

正：It is time we were leaving. (可用)

正：It is time we leave. (少见, 非正式美国口语)

2. 其它几点注意处：

(1) 其中的It is有时根据情况也可改为It was, 其后的时态不受影响：

你该上床睡觉了。

正：It is time you went to bed. (指现在而言)

正：It was time you went to bed. (指过去而言)

(2) time前可以用high, about等修饰。

It is high time you told her the truth. 你该把真相告诉她了。

It is about time that I wrote her a letter. 我该给她写封信了。

9. 什么是含蓄虚拟语气

He studied hard, otherwise he ______ so hard a test.

A. didn’t pass           B. couldn’t pass       C. hadn’t passed      D. couldn’t have passed

此题应选D。其中的 otherwise 含蓄地暗示一种虚拟条件, 相当于if he hadn’t studied hard。

英语中用某种词汇或语法手段含蓄地暗示虚拟条件的方式比较多, 下面略举几例, 供考生参考：

With more money [If I had more money], I could do it better. 要是我有更多的钱, 我会做得更好。

But for his help [If it were not for his help], we couldn’t get over the difficulties. 要是没有他的帮助, 我们就无法克服这些困难。

I’m really busy, or[if I weren’t so busy] I wouldcertainly go with you. 我确实太忙了, 要不然我一定跟你们一块儿去。

Meeting[If we had met] anywhere else, we couldn’thave recognized each other. 要是在别处见面, 我们俩彼此是不会认出来的。

To hear him speak English [If one were to hearhim speak English], one would think him anEnglishman. 你要是听他说英语, 一定会认为他是一个英国人。

An honest man would not say this. [If he were anhonest man, he would not say this]. 一个诚实的人就不会说这样的话。
