( ) 3. —Do you know him well?
—Sure. We ________ friends since ten years ago.
A. were B. have become C. have been
D. have made

Answer 1

首先,答句的时间短语是since 10 years ago,

这和for ten years是一样的效果,

所以横线上的谓语动词需要是完成时的可延续性动词,

become和made都是非延续性的瞬时动词,

所以选B.望采纳！

Answer 2

正确答案: C
答案解析:根据句意可知应该用完成时，所以A答案错误。
have been.表示状态，可以和表示段时间的短语连用。 have made和have become都是瞬间动词，不能和表示一段时间的短语连用。

Answer 3

C. have been
用现在完成时
become强调动作，不能和表示延续的时间段since 10 years ago.连用

Answer 4

选C 过去分词been

Answer 5

C. have been
