(我刚做完作业，对现在的影响是“我现在有空了”) Has she seen the Great Wall yet? (她看过长城了吗？问的是过去动作对现在的经验影响) We have never been to Shanghai. (我们从未去过上海，表示从过去到现在的一种状态) 2.表示动作或状态从过去某一时间开始，持续到现在，并可能继续下去，常与表示一段时间的状语连用。 标志词: for + 一段时间 (for two years), since + 过去的时间点 (since 2010, since last week), how long (多久) 例句: Mr. Wang has taught English for over 20 years.

(她去过英国两次。)(现在人不在英国) 2.have/has gone to: 表示“已经去了某地”，现在人可能在路上或已经在那个地方了。 e.g., —Where is Tom? —He has gone to the library. (汤姆去图书馆了。)(现在人不在这里) 五、 动词过去分词 (p.p.) 的构成 规则变化: 1.与过去式规则相同。 一般加 -ed: work -> worked 2.以不发音e结尾，加 -d: live -> lived 3.以“辅音字母+y”结尾，变y为i再加 -ed: study -> studied 4.重读闭音节结尾，双写尾字母再加 -ed: stop -> stopped 不规则变化: 需要特别记忆，是本单元和今后的学习重点。 see -> saw -> seen do -> did -> done go -> went -> gone / been eat -> ate -> eaten read -> read -> read 第二部分：专项练习卷 A. 基础达标 (Fundamental) 一、 用 have/has 填空。 1.I ________ visited the Forbidden City. 2.She ________ just cleaned her room. 3.How long ________ you lived in this town? 4.They ________ never eaten Beijing Duck. 5.My father ________ gone to Beijing on business. 二、 写出下列动词的过去分词。 1.see ________ 2.do ________ 3.eat ________ 4.live ________ 5.study ________ 6.stop ________ 7.read ________ 8.go ________ 三、 单项选择。 ( ) 1. —______ you ever ______ to the Great Wall? —Yes, twice.

Let me tell you about the Palace Museum. It is more than 600 years old. It was the palace of the Ming and Qing dynasties. I have been there twice. The last time I went there was in 2022. It is huge, beautiful and very interesting. You can learn a lot about Chinese history there. I hope you can come to Beijing one day. I can show you around. Best wishes, Li Hua 学科网（北京）股份有限公司 $
