一、have been to / have gone to / have been in的用法比较

1. have been to意思是“到过，去过”，表示曾经到过某处，但现在人不在那儿。

I have been to Guilin. I went there last year. 我去过桂林，我去年去的。

2. 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。

She has gone to Nanjing. 她已經去南京了。

3. have been in意思是“呆在某处一段时间了”。

You have never been there， have you？ 你以前从未去过那儿，是吗？

二、巧学妙记：同一个意思有四种不同的表达方式

我买这块手表20年了。

I have had this watch for 20 years. （这个句型叫代替法：用一个延续性动词的现在完成时代替终止性动词，然后用“for+一段时间”句型结构）

I bought this watch 20 years ago. （这个句型叫ago法：是用“终止性动词的一般过去式+一段时间+ago”）

It is 20 years since I bought this watch. （这个句型叫强调法：It is+一段时间+since+从句）

Twenty years has passed since I bought this watch. （这个句型叫 passed法：一段时间+ has passed+since+从句）

三、现在完成时与一般过去时的用法比较

1. 一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作;现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。

I saw this film yesterday. （强调动作发生的时间是yesterday）

I have seen this film. （强调对现在的影响，电影的内容已经知道了）

2. 一般过去时和表示过去的时间状语连用，如：...ago， in 2018， in the past， yesterday，then， that day， one day， once （从前）， last week / month / year / night / Monday 等。

3. 现在完成时常和recently （近来）， ever， never， twice， so far （到目前为止）， since， for， in the past / last few years， already （肯定句）， yet （否定、疑问句）， just （刚刚）， before （以前）等连用。
