Activity 2 Grammar.
现在完成时(1)
现在完成时是指“过去发生的动作对现在造成了影响”而且“过去的动作或状态持续到现在并且已经完成”。在现在完成时的句子中，already (已经), just (刚刚)常用于肯定句，放在have和has的后面。yet (还、尚、仍然)常用于否定句和疑问句，放在have和has的后面，也可放在句末。
现在完成时(2)
当表示动作已经完成，并对现在有一定影响时，我们一般用现在完成时。同时，可分别用just, already或yet加以强调或说明。
【辨析】have been to与 have gone to
(1) have gone to表示“已到达某地”。说话时该人不在现场，强调尚未回来(go是方向性动词)。
例：—Where is Jim 吉姆在哪里？
—He has gone to Beijing. 他去北京了。
(2) have been to表示“曾经去过某地”。现在已经不在那里了(be是表示状态)，后可接次数，如once, twice, three times等，表示“去过某地几次”。也可和just, never和ever等连用。
