【知识详解】
1. have/has been to与have/has gone to的区别
(1)have/has been to意为“曾经到过(某地)”, 强调一种经历, 含有现在已离开那儿之意, 常和just, ever, never等词连用, 后也可接次数, 如once, twice, three times等, 表示“到过(某地)几次”。
(2)have/has gone to意为“到(某地)去了”, 强调说话时该人不在现场, 有可能已到了, 也可能正在去的路上。
2. 现在完成时态的时间状语
(1)表示不确定时间的时间状语: already, yet, just, before等副词时间状语。
(2)表示包括“现在”在内的一段时间的时间状语: since. . . , for. . . ; ever, never, recently(最近), today, this week(year), these days(weeks, years), in/during the last/past two years, so far等。
注意: ever和never常位于助动词have/has与过去分词之间。例如:
He has never been late for school.
他从未上学迟到过。

这几周以来我已经收集了十张邮票。
