Question

英语“It is high time that we had to prohibit smoking”有没有语法错误？

Answer 1

had to 改为have to
high time 引导的 后方其实 隐藏了 should 这个情态动词
必须接原形。。而不是 理解为一般现在时。。

追问

用法不是 “ It is high(about) time (that )+ sb did sth ” 么?

追答

疏忽了。

high time 就两种用法。
接原形时，必须把情态动词should 补完整，不能省
另一个是接过去式。。

所以你这个句子 应该也是可以的。

追问

也就是“It is high time that we had to prohibit smoking”和“It is high time that we should have to prohibit smoking”表达意思一样，语法都对，对吧？

追答

是。。。。。。。。。。。。。

Answer 2

have to，一般现在时
