如yesterday(morning、afternoon),last(morning、afternoon）等，除非与for,since连用.
2.现在完成时往往同表示不确定的过去时间状语连用
如already（肯定），yet（否定，疑问），just,before,recently,still,lately,never等：
He has already obtained a scholarship.
I haven't seen much of him recently (lately).
时态

Have they found the missing child yet?
3. 现在完成时常常与表示频度的时间状语连用，
如often,sometimes,ever,never,twice,on several occasion等：
Have you ever been to Beijing
I have never heard Bunny say anything against her.
I have used this pen only three times. It is still good.
George has met that gentleman on several occasions.
