在英语学习中，被动语态的to还原是个让人头疼的问题，但今天老师就来给大家支个招，用一句口诀轻松搞定——“一感二听三让四看半帮助”。

口诀解析

这句口诀涵盖了被动语态中需要还原to的几类常见动词。一感指的是feel；二听包括hear和listen to；三让则是make、have、let；四看有see、watch、look at、observe、notice；半帮助则是help，其后的不定式可带可不带to，但在被动语态中通常要带。 2

以hear为例，主动语态“I heard the girl sing an English song.”变为被动语态时，需还原to，即“The girl was heard to sing an English song.”同样，make、see、watch等动词在被动语态中也需遵循这一规则。 3

为了让大家更清晰地理解，老师特意整理了以下表格：

口诀分类	动词示例	主动语态	被动语态
一感	feel	I felt something move beside me.	Something was felt to move beside me.
二听	hear	I heard the girl sing.	The girl was heard to sing.
三让	make	He makes his sister cry.	His sister is often made to cry.
三让	let	Let me have a try.	I was let to have a try. (但let在被动语态中不常见，了解即可)
四看	see	I saw them play football.	They were seen to play football.
	watch	Mother watched her son play in the park.	Her son was watched to play in the park. (但通常省略to)
	observe	I observed him enter the room.	He was observed to enter the room.
	notice	I noticed him leave.	He was noticed to leave.
半帮助	help	Can you help me (to) carry the box?	I can be helped (to) carry the box. (但通常不这么用，了解即可)
