3.fall over 和fall down 分别是什么意思?
4.I _____(not check) my e-mail today .what did you send to me?
5.I have no idea what _____(happen) while I was asleep.
可以解释一下2,4,5题嘛?可是第五题标准答案是happened!

1. speeches
2. didn't
3. fall over... 落在...之上
fall over 脸朝下跌倒
fall down... 从...摔下
fall down 摔倒
以上两个短语都可以既做不及物动词,单独使用或在后面再加介宾结构,如:
I suddenly fell over/down (from my bike).
也可以把over和down视为介词,如:
I fell over the ground. I fell down my bike.
4. haven't checked
5. was happening

speeches

didn't

fall over 摔倒

fall down 跌倒

可以通用;区别不大。

haven't checked

had happened

你们正在学时态吧!~

didn't

fall over 摔倒

fall down 跌倒

可以通用;区别不大。

haven't checked

had happened

speeches didn't fall over 摔倒 fall down 跌倒 可以通用;区别不大。haven't checked had happened

1.speeches
2.didn't 因为是原来的事而道歉,所以用过去时
3.fall over.....摔倒
fall down.....从...摔下
两者可通用:①它们可以既做不及物动词,单独使用或者在后面再加介宾结构:
eg:My brother fell over/down from the bicyc
