Unit 9 Have you ever been to a museum Section A 1a—1c 一、学习目标:描述某人曾经去过哪些有趣的地方和谈论过去的经历。 能力目标: 掌握如何表达现在完成时重点词语: amusement，neither ,space museum。 重点句子： 1) —Have you ever been to a museum —Yes, I have. I went to the national science museum last year. 2) Let’s go to one tomorrow. 难 点：掌握用现在完成时谈论过去的经历。 二、预习导学 1.1a的词语和对话。 重点单词短语，并结对抽说中文意思。 三、自学检测 〔一〕认真琢磨，细心选择(体会现在完成时和一般过去时的区别)。 〔二〕根据首字母完成单词使句子意思完整, 通顺 1.

So I’m going to an a 四、合作探究 现在完成时〔一〕 I．用法：现在完成时表示过去发生的动作对现在造成的影响或结果。常与以下时间状语连用：just , already, yet, ever, never, before, several times。 现在完成时不能和表示过去的时间〔如：yesterday, last, year, in 1976, two days ago, just now, when she came in 等〕连用。 〔1〕现在完成时表示过去发生的动作对现在的影响。 I have studied English. 表示I know a little English. He has already come back. 表示He is here now. 常与already, yet, just, recently, ever, never, before等表示不确定时间的时间状语连用。 〔2〕现在完成时表示从过去一直持续到现在的动作或状态。 She has been ill for 3 days. He has worked in the bank since 1990. 此时，句中谓语动词通常是延续性动词，且常与表示一段时间的时间状语连用。如：these days, all this year, recently, for ＋时间段以及since＋时间点等等。 II. 构成：have / has ＋动词过去分词 〔1〕has用于主语是第三人称单数，have用于其它人称。 〔2〕动词的过去分词构成分为规那么动词和不规那么动词。规那么动词在词尾加ed，其规那么与过去式一样。 不规那么动词要记住。例如：take－taken, go－gone等。 = 3 \* ROMAN III.区分 have/has been to 与have/has gone to have /has been to 和 have/has gone to 都是指已经去了某个地方，但是 have /has been to 强调的是曾经去了某个地方并回来了； have/has gone to强调的是去了某个地方还没有回来。 --Have you ever been to Shanghai --Yes, several times. -- Where is Mr. Wang？-- He has gone to Shanghai. 六、学以致用选做题 单项选择。 ( ) 1、Have? you? met?
