Guide students to find the lines all contain the structure “have/has done”. Page 7，5 1. Present the two sentences and ask students to read and translate. · I haven't told Maddie yet how she has changed me. · I have already learnt that I am what I am. 2. Guide students to pay attention to the verb forms and circle the structure “have/has+ done” in the sentences. 3. Tell students that the sentences are in present perfect tense which is the target grammar in the class. Understanding ideas（6—8） ★Step 2　Grammar focus learning【语法学习】 现在完成时(1) 1、 用法 现在完成时表示在以前某个时间已经发生的行为或曾经做过的事情对目前有某种影响。常与这些副词及短语连用：just, already, yet, recently, before, ever, never, twice, so far, in the past three years等。 E.g. I have already seen the film. I don’t want to see it again. He has just finished his homework. All the tickets have sold out. I have never talked with Mr. Li before. 二、基本结构 1.肯定句：主语 + have/has + 过去分词+... E.g. I have bought many books about European history. They have finished the housework. 2.否定句：主语 + have/has + not + 过去分词+... E.g. The Simpsons haven’t been to Canada since the day they left. Eric hasn’t got his plane ticket yet. 3.一般疑问句结构及回答： —Have/Has+主语+过去分词+...? —Yes, 主语+have/has. /No, 主语+haven’t/hasn’t. E.g. — Have you ever read Sherlock Holmes? — Yes, I have./No, I haven’t. — Has he decided which book to write about yet? — Yes, he has./No, he hasn’t. 三、动词的过去分词 1.规则变化的构成方法： ①一般在词尾直接加-ed：E.g.help—helped ②以不发音的e结尾的动词，词尾加-d：E.g.live—lived ③以“辅音字母+y”结尾的动词，先将y变成i, 再加-ed：E.g.carry—carried ④以重读闭音节结尾，且末尾只有一个辅音字母的动词，先双写该辅音字母，再加-ed：E.g.stop—stopped 2.不规则动词的变化形式 原形—过去式—过去分词 be—was/were—been find—found—found do—did—done have—had—had eat—ate—eaten make—made—made go—went—gone let—let—let see—saw—seen put—put—put 四、现在完成时与一般过去时的区别 现在完成时与一般过去时都表示在过去做的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等; 一般过去时则只表示过去的事实，不表示和现在的关系。所以，一些表示过去的固定时间状语只能与一般过去时连用，如ago,last或由when(何时)引起的问句都不能与现在完成时连用。 E.g. I have just cleaned my room. I cleaned my room yesterday. ★Step 3　While-task【过程任务】 Page 7，6 1.Show the words and phrases to students, then ask them to write sentences with the present perfect tense. 2.Check the answers with the class. Answers: ①I have just cut my long hair. ②She has never worried about her looks. ③I have just painted a beautiful flower on my face. ④Chris has always worn a pair of glasses. ⑤Jessica has already changed her opinion on her looks. Page 7，7 1.Show the paragraph to students, then ask them to read it and rewrite the underlined sentences using the present perfect tense. 2.Check the answers with the class. Answers: ①I have been the tallest student in my class. ②I have sat on the last row. ③“You must be good at basketball.”My classmates have always said that. ④I have learnt to accept my height now. ★Step 4　Post-task【后续任务】 Page 8，8 1. Ask students to work in pairs and then discuss the experience of accepting their looks. 2. Give students an example as follows. Experience of accepting yourself · Which part of your looks are you not happy with? · How did you feel about it before? · How do you feel about it now? · Why did you change your view of it? · What can you learn from this experience? 3. Ask students to use the words from the reading passage and the useful expressions. 4.Show the useful expressions to help them to organize their ideas. Useful expressions: · I was not happy with my ... · ... is a good way to... · What do you think of... now? · For example, ... · I have already ... · Why not ...? 5.Choose some students to share their answers. ★Step 5　Summary　【课堂小结】 Ask students to use the students’ self-assessment form to check what they have learned in this lesson.
