小学英语选择题，谁进来帮忙回答？

in three months 和 after three months 都是三个月以后 的意思。那么两者在有什么区别呢？

如：I'll start......three months A。 after B in C。before

Do............exercises. You'll get stronger .

A. any B. many C.more

in three months 应该是指三个月内，

B，我会在三个月之内开始

C，做更多锻炼

B C in three months表示从说话点后的将来，还没到那个时间 after three months一般是用来叙述已经过去了的事，

I'll start（ in） three months .三个月内我会开始。

Do（more）.exercises. You'll get stronger .多运动，你才能更强壮！

in +时间段：与将来时连用 after +时间段：与过去时连用 after +时间点：可与将来时连用 He will be back in two hours. He came back after two hours. He will be back after two o'clock. in+一段时间表示将来时 如:I'll come back in a week in＋一段时间也可用于过去时，意思是”．．．内” 如:he came in two days. 而after＋一段时间通常只能用于过去时，不能用于将来时 如：he came back after a week
