注意：表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，表示次数：一次once; 二次: twice, 三次：three times…, ever, never等时间状语。

如： I have been to Beijing twice.我去过北京二次。

三. have been in, have been to 与 have gone to 的用法区别

（一）.have(has) been in 表示“在某地呆多长时间”，

常与表示一段时间的状语连用，如：since, for, how long 等。例如：

Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了。

此外还有这些搭配： have been here (there) /at home (school) /on the farm

have been here (there) / abroad

（二）.have(has)been to表示“曾经去过某地”，现在已经不在那里了。

可与just, ever, never等连用，例如：

I have just been to the post office. 我刚才去邮局了。

Mary has never been to the Great Wall. 玛丽从未去过长城。

Have you ever been to Hangzhou? 你曾经去过杭州吗？

have(has) been to 后面可接次数，表示去过某地几次。例如：

I have been to Beijing three times. 我去过北京三次。

They have been to that village several times. 他们去过那个村庄好几次了。

（三）.have(has) gone to意为“到某地去了”，表示到了某地或正在去某地的途中。总之，说话时该人不在现场，一般不用第一、第二人称代词作句子的主语。

例如：----Where is Tom? ----He has gone to the bookshop. 汤姆在哪里？他到书店去

Jack Johnson has gone to London. 杰克.约翰逊到伦敦去了。
