1.“不及物动词+介词/副词”构成的短语用于被动语态时，要把它们作为整体看待，介词或副词不可与该结构中的动词拆开或漏掉。如：
The child was looked after by his grandmother last year.
The soil was washed away by the flood.
关于被动语态的几点注意事项
2. 含有双宾语的主动句变被动句时，可将主动句中的直接宾语(指物)或间接宾语(指人)变为被动句中的主语。如果把主动句中的直接宾语变为被动句中的主语，则需在间接宾语前加适当的介词to或for。如：
主动句
We sent our teachers some flowers on Teachers’ Day.
被动句
Some flowers were sent to our teachers on Teachers’ Day (by us). (直接宾语作主语)
Our teachers were sent some flowers on Teachers’ Day (by us). (间接宾语作主语)
3. 有些动词常用其主动形式表示被动意义，常见的有：
①sell, wash, write等用作不及物动词，且常与表示效果或程度的副词连用。如：
This kind of fruit sold well in this area last month.
②表示感觉、知觉的系动词feel, sound, taste, smell等。如：
The song sounded noisy.
4. 在主动句中，使役动词(如make等)和感官动词(如see, watch, notice, hear等)后面常接不带to的动词不定式作宾语补足语；但在被动句中，这些词后面的动词不定式都需要带to。如：
She made her children wash their hands before a meal. →
Her children were made to wash their hands before a meal by her.
They saw Jack play basketball on the playground. →
Jack was seen to play basketball on the playground (by them).
