I thought we'd be late for the concert,           we ended up getting there ahead of time.

but

or

so

for

考查连词。句意：我以为我们音乐会迟到了，但是我们提前到达了那里。but 但是；or 或者；so 因此；for因为；两个分句在意义上bu是转折关系，故用but。故选A项。

Not at all

Not exactly

Not especially

Not really

考查情景交际用语。句意：---你错过了开会。---我在会议结束前五分钟到达会场。可以看出答话者认为对方讲话不够确切。A. Not at all一点也不；不客气；B. Not exactly不确切   C.Not especially不是特别 D.Not really不是真的。故选B项。

used to

used to be

used to do

was used to

考查词组和省略式，used to do“过去常常’,be used to do “被用来做”，句意是：--你现在是志愿者吗？--不但我过去是，去年我为市运动会工作。可以排除D项，因为这是省略句，完整的是I used to be a volunteer。英语中如果不定式的部分是重复上文可以省略to后面的内容，但是如果to后面是be动词或助动词have，就不省略。选B。

My mom suggest that we           eat out for a change this weekend.

should

might

could

would
