4时4态 加被动 例句：I will have been being done - will have be be do - 频率副词位置

4时4态

频率副词的用法和位置：放在实义动词之前、放在be 动词之后、放在情态动词之后。

频率副词的位置一般是放在实义动词之前、放在be 动词之后、放在情态动词之后。放在be动词之后：She is sometimes very busy.她有时很忙。在第一个动词或情态动词之后：I will never forgot the first time I meet you.我永远都忘不了第一次和你见面的时候。在实义动词之前：We often go there.我们常去那。 sometimes也可以放在句首、句中、句末，often也可以放在句末：Sometimes she writes to me.她有时候写信给我。She writes to me often.她经常给我写信。

频率副词位置总结：
1. be动词之后
2. will have be be 这四个位置，第一个位置的后面
3. 情态动词和助动词一个都没有，就放在实义动词前面
举例： Such a thing has never been heard of before.(以前从未听过这样的事。)
