句型變化：

★變疑問句將助動詞移到句首，變否定句在助動詞后面加not.

e.g. Have you lost your pen? I have not lost my pen.

★肯定回答及否定回答

Yes, I have. No, I have not.

★特殊疑問句：

What have you done?

一般過去時與現(xiàn)在完成時的區(qū)別：

凡是有明確的表示過去的時間狀語的句子為過去時

注意：有些動詞表示的動作有一個終點，不能再延續(xù)，因此不能和表示一段時間狀語連用

錯：I’ve left Beijing for 3 days.

對：I left Beijing 3 days ago. I have been away from being for 3 days.
