考点精讲
经典考点一:让步状语从句
(1)让步状语从句通常由although, though等连词引导。例如:
Though he is young, he knows a lot.
Although I am tired, I must go on working.
易错考点:although只能用在句首,而though既可以放句首也可以放句末。
(2)although(though)不能和but用在同一个句子中。例如:
Though it was raining hard, but he still went out. (╳)
应该说:Though it was raining hard, he still went out.或It was raining hard, but he still went out.
经典考点二:时间状语从句
时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。
It was raining hard when I got to school yesterday.
He won’t believe it until he sees it with his own eyes.
when,while,as辨析:
①when引导的从句,动词既可以是延续性的,也可以是终止性的。一般来说,当主句的动作正在进行时,when引导的从句的动作才发生;
例:He was riding to school when he was hit by a car this morning. 当他被一辆小汽车撞到的时候他正骑车上学。
②while引导的从句中,动词只能是延续性的,一般来说,当while引导的从句的动作正在进行时,主句的动作才发生;
例:They were singing while we were dancing. 我们在唱歌的时候他们在跳舞。
③as表示随着短暂动作的发生,另一行为伴随发生。
例:She sang as she walked. 她一边走一边唱歌。
★当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”( 用现在时态表示将来的动作或状态)
since: “自从”, ★重要经典考点: 现在完成时 (主句) + since+ 一般过去时 (从句)
Mr. Green has made quite a few friends since three years ago.
It is four years since my sister lived in Beijing.
→★It is +一段时间+ since+ 从句 (一般过去时)
not….....until/ till....... 直到……才
….....till........ 直到……为止
① until表示动作、状态的持续,强调“一直到……为止”,或强调某个动作或状态一直持续到另一个动作或状态出现之前。常与表示延续性动作的动词连用。
例:I waited until three o’clock, but he didn’t come.
②not … until表示“到……为止;直到……才”,常与表示瞬间性动作的动词连用。
例:The children didn’t come home until it was dark.
注意:一旦看到否定,再看到选项中有until,可以迅速联想到“not......until......”结构,再结合句意进行判断选择。
经典考点三:目的状语从句和结果状语从句
①so that 表示为了...(表目的)
②so...that...,such...that... 表示如此...以至于...
so+形容词/副词+that从句
例:Nanjing is so beautiful that lots of visitors come here every year.
南京如此美以至于每年许多游客来这。
so+形容词+a/an+可数名词的单数+that从句
例:Nanjing is so beautiful a city that lots of visitors come here every year.
南京如此美以至于每年许多游客来这。
so+many/much/few
