Question

________ three times，but she still couldn’t follow what the old man said．

A．Having told	B．Having been told
C．She had been told	D．Though she had been told

Answer 1

C

试题分析：因为逗号后是句子，并有连词but，所以前面的句子不用连词，故排除D；又因为but是并列连词，所以它的前面也是一个句子，故排除AB，应选C。
点评：本题难度适中。But可连接词、短语和句子，还可用于道歉的表达之后；用在某些否定语后，表示“只……”：
He eats nothing but hamburgers. 他只吃汉堡包。
She knows no one but you. 她只认识你。
You have nobody but yourself to blame. 只能怪你自己。
No one but me saw her. 只有我看见他。
7. 用于next (last) but one 中，表示“隔壁再过去”“倒数第……”
He lives in the next house but one. 他住在隔壁再过去一家。
He was the last but one to arrive. 他是倒数第二个到的。
8. can’t help but 不由得不……
You can’t help but respect them. 你不由得不尊敬他们。
When they gave him a ticket to the game, he couldn’t help but go. 他们给了他一张看球赛的票，他不由得不去。
I can’t help but wonder what I should do next. 我不由得不想知道下一步该怎么办。
即学即练：Excuse me, _____I don’t think that’s quite true.
A．but          B．since      C．so              D．although
解析：A。句意：很抱歉，我认为这与事实略有出入。
