suggest的用法我用的对吗

1，虚拟语气，正确！
2.suggest doing sth.中间加逻辑主语，也可以的
3.不正确，应该是suggest us to go

I suggested going for a walk.

I suggest you do what he says
没有suggest to sb to do sth.

3.应为 us to go
suggest sb. to do sth.是固定搭配

看完以下用法你就清楚了

动词suggest有如下一些用法:
一、 有"建议"的意思.advise， propose 也有此义,请比较它们用法的异同:
1) 都可接名词作宾语
She suggested / advised / proposed an early start. 她建议早一点出发.
We suggested / advised / proposed a visit to the museum the next day. 我们建议明天去参观博物馆.
2) 都可接动名词作宾语
I suggested / advised / proposed putting off the sports meet. 我建议将运动会延期.
They suggested / advised / proposed waiting until the proper time. 他们建议(我们)等到恰当的时机才行动.
3) 都可接that 宾语从句,that从句用should+动词原形,should可以省略.
She suggested / advised / proposed that the class meeting (should) not be held on Saturday. 她建议班会不要在星期六举行.
We suggested / advised / proposed that he (should) go and make an apology to his teacher. 我们建议他去向老师道歉.
