no sooner…than(刚……就)。例如:
Hardly had it grown dark when he realized it was
too late to return home.
Tips在before, after等引导的时间状语从句中,由于这些连词本身已经表示出时间先后,所以主句或从句的谓语动词可以用一般过去时来代替过去完成时。例:
She and her family hid away for nearly twenty-five months before they were discovered.
在when引导的时间状语从句中,谓语动词的动作发生后,主句谓语动词的动作紧挨着发生,这时两者均用一般过去时。例如:

How many races have you taken part in?
3.现在完成进行时与所有进行时态一样带有感彩,可使表达显得生动,而现在完成时往往只标明一个事实,一种影响或结果,不带感彩。例如:
What have you been doing? You look fed up.
(你一直在干什么呀?你看上去很不爽。)Tips –过去完成进行时表示动作从过去某时开始,一直延续到过去另一时间。例如:

主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。I.主动和被动的转换II. 被动语态的使用场合不知道动作的执行者,没有必要知道动作的执行者或强调动作的承受者时,常使用被动语态。例如:

Unlike today’s Olympic Games, the ancient
games were always held at the same place.
The trip is organized by a well-known tourist
company with a good reputation.III.应注意的问题不能用于被动语态的动词
一般说来,只有及物动词才有被动语态,但少数及物动词如have, leave, become, cost, enter, reach, suit, benefit, lack等以及短语动词take place, lose heart, break out, belong to, consist of等,一般不能用于被动语态。例如:

从形式上看,被动语态和“be+过去分词”的系表结构完全一样,但它们的区别在于:被动语态表示动作,其后常跟有by短语,表示动作的执行者;系表结构表示状态,其后一般不跟by短语。试比较:
The teacher was pleased with her answer.
The teacher was pleased by her answer.
The door is closed.

light and can be folded easily.
