s far 迄今为止 fr a lng time 很长一段时间
by nw 到现在为止 in recent years 在最近几年里
in/during/ver the past/last years在过去的几年里
需要注意的点：
1．与一般过去时的区别
一般过去时所表示的动作或状态与现在的情况没有联系，而现在完成时则强调与现在的情况有联系。
The museum was pened t the public last year.
The museum has been pened t the public.
2.非延续性动词不与阶段性时间状语语连用
如brrw，finish，begin，buy，marry，pen，等构成的现在完成时不能与表示一段时间的状语连用。若要表达相应的意思，则要换成延续性动词或改变句式。
The experiment was finished tw weeks ag.
It is tw weeks since the experiment was finished.
3.动词短语中的介词或副词不可省略。
It is said that the case has been lked int.
4. 带有双宾语的动词变为被动语态时,一般将间接宾语变为被动语态的主语，若将直接宾语变为被动语态的主语时，间接宾语前面要用相应的介词。
The cmpany has given him a chance t wrk abrad recently. →He has been given a chance t wrk abrad recently (by the cmpany)．
→A chance t wrk abrad has been given t him recently (by the cmpany)．
