大家快来帮帮忙啊!帮忙选一个答案,最好能说明为什么选这个答案!谢谢!

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

xzcrystal的回答是最正确的

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

选 D
help sb to do sth: 习惯用法,帮助某人做某事

A

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

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.

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

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