是否有have a difficulty doing sth. It's difficult to do sth. It's a good time to do sth.

Question

have a good time doing sth.
have problem doing sth.
have a difficult time doing sth.的形式？
还有，a good time是名词吗？
如果有上述形式，和a good time是名词的话，我可否总结成：It's +n.+to do sth. It's +adj.+to do sth.
have +n.+doing sth ？

Answer 1

have difficulty (in) doing sth.意为做某事有困难
It's +adj./n+(for/of sb.)+to do sth这是一个固定句型
而你说的have句型一般都是存在于固定短语中的，得需要慢慢积累，have一般的用法为have sth to do有事情要做, have sb do sth,让某人做某事 have sth done是某物被。。。
希望可以帮到你

Answer 2

是HAVE DIFFICULTY DOING没有IN........后边两个是有的。。。形式大多为it's +形容词+TO DO或者IT'S+ 形容词+FOR/OF+人+TO DO .....It's +n.+to do sth以及have +n.+doing sth 都不能作为普遍的用法。。只是有些特殊的固定搭配这么用。。慢慢积累喽。别急。。。。。。。

Answer 3

have +n.+doing sth 和 It's +adj.+to do sth可以
It's +n. 大多也是加to do 但有极少个例要加doing 如 use 这个名词
