英语的一点选择填空

Last weekend,I wentto the City Zoo but ___the African elephant
A saw B see C didn't see D weren't see
选C。but前如果用了助动词do的任何形式，后面则可省略可能需要用到的do的形式
此句中，前半句没有do的任何形式，所以后面的didn't不能省略。

Why did you leave Jane's party early last night
It __time for me ___home .I had to.
A is go B was to go V is going D was go
选B。
固定吧配。It's time for sb. to do sth.

My friend got___school late this morning , but he usually ___(arrive)on time
答案：to; arrives
固定搭配： get to = arrive in/ at = reach
因为有了usually, 所以arrive要用一般现在时

My English teacher asked me ___(stay) after school and have a talk with her
答案： to stay
固定搭配：ask sb. to do sth.
ask me to stay after school and to have a talk with her.
因为to 重复，所以去掉。。

Everyone in our class ___(write)a conversation now
答案：is writing
everyone作主语，谓语动词用单数，又由于now的关系要用现在进行时态

C
B
arrives
to stay<
