第三题

感觉是have grounds to do sth和have grounds for doing sth的比较。

查了Longman,两种说法都有，但感觉Have grounds to do sth的主语和to do sth应该是一致的，如 Did the police have reasonable grounds to arrest him? 而grounds for doing sth并不要求主语一致，如：There are strong grounds for believing his statement.

The interval between arrest and trial can be up to six months.
