很高兴为你解答.
Last night I went out with some friends to the new theatre.I ( had never
been ) to the new theatre before.when we (arrived )at the theatre,the
play (had already started ).I (enjoyed ) the play very much,although
I (had seen )it once before.I (saw) some neighbours of mine at the
theatre,but I (couldn't speak) to them.There ( were) too many
people.I looked for them at the end of the play,but they ( had already
left).As the weather ( was) fine,we (decided) to walk to
the restaurant.But when we (got) to the restaurant,we found
to the restaurant ,we found that it ( had been closed).We took a taxi home,as the last bus ( had already gone)
解析：根据 last night ,全文基本采用过去式.第一个根据before ,是发生在过去的过去,用过完成时态.第三空,在我们到之前就开始了,也用过去完成时.第五个根据before ,过去完成时.第九个,我去找他们的时候,他们已经离开了,是过去的过去,还是完成时.第十三空,餐馆是被关,且在我们去之前就关了,用过去完成被动时态.最后一空,也是末班车走了是发生在我们坐出租车前,过去的过去,还是过去完成时.
其实没什么好讲的,自己弄清楚就行了.
祝开心~!
