instead通常在句末,如果在句首,后要用逗号。
He isn't here. Ask Lucy instead.
she didn't answer me.Instead, she asked me another question.
instead of 可以再句首,句中 表示:代替,而不是
Instead of shopping,we stayed at home.
I'll go instead of you.
二者的转换:
He didn't answer me, Instead, he asked me another question。
= He asked me another question instead of answering me.
