 Ⅴ、So和not的替代性省略

 用于避免重复前面所说过的内容,替代词so/not替代肯定或否定的名词性从句。可与believe,do,expect,fear,guess,hope,say,speak,suppose,think,I’m afraid等连用

 现在完成时被动语态可用来强调发生在过去的被动性动作对现在造成影响。

 现在完成时被动语态还可强调到目前为止某被动性动作或状态已存在若干时间。

 will/shall be done除用于一般将来时构成被动语态外,还可用于什么场合构成被动语态?

 will/shall be done除用于一般将来时构成被动语态外,还可用来表示有固定性条件就会有规律性被动结果。

 has/have been done是否可用于一般将来时构成被动语态?
