在备考英语四级的过程中,各位同学一定不要忽略了语法,语法在各个题型中都有体现,而且语法学的好对做题也有非常大的帮助,本文就为各位同学介绍了英语四级常用语法,供同学们参考。
状语从句
状语从句中以下四种从句考得较多,这里给予简单介绍。
1) 时间状语从句
时间状语从句主要由以下连词引导:when, whenever, as, while, since, until, till, before, after, as soon as, once, hardly (scarcely) … when, no sooner … than。
I will discuss the matter with you when we meet tomorrow.
He didn’t go to sleep until he finished doing his homework.
You have changed a lot since we met last time.
I will tell you the news the instant I know.
Directly the teacher came in everyone was quiet.
Note:
① before除了可表示 “在…之前”外,还可用来强调主句所表达的时间、距离很长或花费的力量相比较大,可译为“…才”。(“not … before” 可用来强调主句所表达的时间、距离很短或花费的力量相比较小,可译为“…就”)。
It was a long time before I got to sleep again.
They had not been married a month before they quarreled.
② 如果位于when引导的分句之前的主句使用过去进行时、过去完成时或“was/were about to, was/were on the point of”等结构时,when表示突然发生某事,可译为“正在…突然”或“刚…就”等。这时,不能够用as或while来代替when。
I was walking on the street when I ran into my old friend John.
She had just fallen asleep when the telephone rang.
We were about to leave when it began to rain.
2) 条件状语从句
条件状语从句主要由以下连词引导:if, unless, providing/provided3 (that), suppose/supposing (that), on condition (that), as/so long as, in case等。
I shall return next Thursday unless something unexpected6 happens.
I will go provided that you go with me.
Please give this letter to John in case he comes.
3) 让步状语从句
让步状语从句主要由以下连词引导:though, although, even if, even though, whatever, however, whoever7, wherever, no matter how/ what/ where/ when等。以下介绍几种较特殊的让步状语从句。
(1) while引导的让步状语从句多放在句首,while相当于although,表示“尽管”,“虽然”。
While I admit I did it, I didn’t intend to.
While I understand what you say, I can’t agree with you.
(2) 短语“even now/then/so”相当于“though it is/was true”,表示“尽管如此”,“尽管这样”。
The fire was out, but even so, the smell of smoke was strong.
(3) as引导的让步状语从句要倒装。
Child as he was, he could speak four languages.
Hard as she tried, she failed to get the job.
4) 比较状语从句
比较状语从句主要由以下连词引导:(not) as … as, (not) the same as, (not) such … as, not so … as, than, the + 比较级…, the +比较级…等。
