本例主要考查现在完成时的用法。现在完成时表示过去某一时刻开始的动作或状态，对现在造成的影响或结果，且常与since, for, already, yet, ever, never, before, in the past…years等连用。如：Have you read the book before?本例since后接过去的某一点表达在某地呆过多长时间，要用have(has)been in.主语依Miss Smith而定。
此外，本例还考查have been to(in), have gone to的区别。have been to意思是“到过，去过”，表示曾到过某处，但现在人不在那儿；have been in表示曾在某地方呆了多长时间；have gone to意思是“去了”，表示已经去了某地，现在人可能在去的途中或已在那儿了。例如：
I have been to Shenzhen. I went there last year.
He has been in the league for two months.
The Greens have gone to England for a holiday.
