* Present Perfect Tense

Rebecca has lived here for 10 years. Rebecca 已經在這裡住了10年。 Rebecca has lived here since 2001. Rebecca 自 2001年以來一直住在這裡。 I have been here for two hours. 我在這裡已經兩個鐘頭。 I have been here since 10 o'clock. 從 10點開始我就一直在這裡。

因為 have/has 是助動詞，所以例句 5~7 的否定句的變化如下: 5. Sue has not paid the bill. 6. We have not drunk the tea. 7. The students have not reviewed the lesson.

做了否定句，疑問句呢？ 5. Has Sue paid the bill? Yes, she has. 　No, she has not. 或 No, she hasn't. 6. Have you drunk the tea? Yes, we have. 　No, we have not. 或 No, we haven't. 7. Have the students reviewed the lesson? Yes, they have. 　No, they have not. 或 No, they haven't.

"been to" 與 "gone to" 用法不同 He has been to Japan. 他曾去過日本。 He has gone to Japan. 他去日本了。 Have you ever been to Japan? Yes, I went to Tokyo last month. 你去過日本嗎？是的，我上個月去過東京。 Is Andy in Japan? Yes, he's gone to Japan. He'll be back next month. Andy 人在日本嗎？是的，他去了日本。他將在下個月回來。 he's = he has; he'll = he will been to 是「去過」某地，且現在已經回來了。 gone to 是「去了」某地，但是還沒回來。
