Lisa has read five books since the end of the last month.注意：（1）其中already用于肯定句，否定句则要改成yet,用于句末。Never表否定，改成一般疑问句要用ever。e.g. I have already had my breakfast. Have you had your breakfast yet?He has never been to America.Has he ever been to America? (2 ). since后接时间点或时间段+ago，而for 后接时间段，两者都必须和持续性动词连用。 e.g. We have lived here since 1997. They have worked as guards for three weeks.3.“have/has been to+地点”表示“曾经去过某地”，现在已经回来，不在该地了；“have/has gone to+地点”表示“已去了某地”，可能在途中也可能还在目的地。 “ have/has been in+地点” 表示“呆在某地多久”4. 瞬间动词用一般过去时， 持续性动词用现在完成时。两者可互相转化。 反馈检测一、改写同义句(1）I borrowed the book a week ago.
