选A
这题有很多选法,可填
help to do ,help do ,help with
在备选答案中只有HELP DO,所以选A,因为这里有HAVE TO所以HELP不加S．所以D错了．
help sb (to) do sth= help sb with sth

选 D
help sb to do sth: 习惯用法，帮助某人做某事

A have to do stj.
help sb. doing sth.

A
have to情态动词 后面动词原型
help sb (to) do sth

You have to help your mother do the housework.
To use 'helps' : My mother helps me with my homework.

A

A you have to = you must .所以B,D两个排除,因为是you.不是第3人称单数
然后根据习惯用法 help sb do sth
按照题目选A

选A.help,do
help sb (to) do sth 帮某人做某事,to可以省略.
have to 意思是"不得不",后跟动词原形.
