现在完成时(三)
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。
其结构是：have / has +动词的过去分词
与already, just, yet等副词连用时，already, just一般置于have/has 之后，用于肯定句中；在否定句中则要用yet 表示“还，未”。
for 和 since 在现在完成时中的应用：
for与since都能与现在完成时连用，但区别较大：
(1) for后须接“时间段”
He has studied English for five years.
他学英语5年了。
(2) since后须接“时间点”
He has studied English since 1999.
他从1999年开始学英语。
(3) 二者可以转换：for + 一段时间 = since + 一段时间 + ago
He has been here for five weeks. = He has been here since five weeks ago.
他到这儿已经有五个星期了。
(4) since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。
(5) 均须与延续性动词连用，也可以与非延续性动词的否定式连用。
