As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason.
随着年龄的增长,我们用力量换来了机敏,以速度换来了严谨,以热情换来了理智;
注：1when还可作并列连词,其意义为“那时,这时”,相当于and at this/that time;常用于下列句式：
doing ...某人正在干某事就在这时……
about to/ going to do ...某人正打算干某事就在这时……
has just done ...某人刚干了某事就在这时……
2如果主句表示的是短暂动作,而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时,when,while与as可互换使用;如：

2、before/ after

3、until, till, not...until
1)肯定句：主句的谓语是延续性动词,主从句均为肯定式,意为“某动作一直
持续到某时间点才停止”
Please wait until I come back.等我回来;
2)否定句：主句的谓语是非延续性动作,从句为肯定式,意为“某动作一直到
时间点才开始”
He won’t go to be d till/until she returns.
3)Till不可以用在句首,而until可以
Until you told me I had no idea of it.
4not…until句型中的强调和倒装用法
It was not until you told me that I had any idea of it.
Not until you told me did I have any idea if it.

行时态

hardly/no sooner主句用过去完成时,when/than引导的从句用一般过去时,固定结构

each/every time和the next time

because/as由于/for/since既然/now that/seeing that/considering that…

He resigned partly because he was old and partly because he was bored with the work.
I didn’t help, not because I was unwilling, but because I was unable
to do it.
2）as和since所提出的原因是已知的,或是句中不重要的部分,since较as 稍正式一些

Since you don’t trust him, you should not employ him.
3）for,一种补充说明,而且for引导的句子不能放在句首,for是并列连词He seldom goes out now, for he is very old.
4）not that…but that...“不是因为……而是因为……”
It’s not that I’m dissatisfied, but that I have my own business to attend to.
5 in that多出现主句之后；seeing that因为,鉴于；considering that因为,考虑到

only if 只有,用陈述语气
You’ll succeed only if you put all your heart into it.
4 provided/ providing that“在……条件下”,“要是”,“以……为条件”
on condition that
under the condition that
suppose/ supposing that“假定”,主句多是疑问句
granted/ granting that “假定…….”,“就算是”,有浓厚的让步意义,可意为“姑且”
