关于强调句的一个问题~
1.I'll leave when he comes.可不可以用it型强调句强调时间状语?It is when he comes that I'll leave.
2.Having breakfast in the room,I'll relax myself.(顺便问一下这里I要不要用将来时?)
非谓语成分having breakfast in the room可以作为强调成分吗?It is having breakfast in the room that I'll relax myself.

1可以用it型强调句强调时间状语
2 非谓语一般不用在强调中,It is after i have breakfast in the room that i will enjoy myself.
