用法小窍门：描述过去的动作，若句中有yesterday , last week, three days ago, in 1996等过去具体时间就一定用一般过去时。若 没有，常用现在完成时。所以When问句不能用现在完成时。When 询问的是具体时间。
A：Have you finished your homework yet?
B: Yes, I have.
A: When did you finish it?
B: Yesterday evening.
1.He ____________(work) out the math and now he is explaining it to us.

B
have been in 在某地呆了多长时间”，
常与表示时间的状语连用
考查词组have/has been in / to与have/has gone to的区别:
例1. Miss Green isn‘t in the office . she_______ to the library .
Ａ.has gone Ｂ. went Ｃ.will go Ｄ. has been
例2. My parents ______ Shandong for ten years .
Ａ. have been in Ｂ. have been to　
Ｃ. have gone to Ｄ.have been
简析：“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。”故例1、2的正确答案皆为A。
A
