二、在when, while, if, as if, though, until, once, whether, unless等连接的状语从句中, 常省略跟主句相同的主语和be动词。

当我有困难时总是找她帮助。
The letter is to be left here until (it is) called for. 这封信留在这里待领。
三、有形式主语it的主语从句可省略that。
It is an honor (that) I was invited to your birthday party.
我很荣幸被邀请参加你的生日聚会。

四、在限制性定语从句中可省略作宾语的关系代词whom, which, that。

Is this the radio (that/which) you bought last Saturday?
这是你上周六买的收音机吗?
五、在direction(方向), way(方式), distance(距离), time(时间), times(倍数)等后面所接的定语从句中常省略that, which, in which。
The direction (in which) we move a body can be changed.
我们移动物体的方向是可以改变的。
The distance (which或that)light travels in one second is 300, 000 kilometers.
