答案：C

“though”,especially spoken,is used at the end of a clause to add a fact or opinion which makes what you have just said seem less important,or to add a very different fact or opinion etc.又如:I expect you’re right.I’ll ask him,though.She promised to phone.I heard noting,though.D项中anyway相当于anyhow,也是一个修饰整个句子的副词,常置于句尾,but anyway is used to say that someone does something or that something happens in spite of a problem。（无论如何,即使如此,至少）,如:He said didn’t know much about computers but that he’d try and help us anyway.
