He stops to do his homework. He stops doing his homework. Class begins, please stop talking. We are all tired, stop to have a rest. 3. remember/forget doing sth. 记得/忘记做过某事 （事情已做） remember/forget to do sth. 记得/忘记要去做某事 （事情还没做） E.g. Please remember to eat lunch. I am sorry, I forget to my homework. I remember playing computer with my sister yesterday. I forget calling you.4. no more & not.any more & no longer & not.any longer 1) no more = not.any more表示数量和程度的“不再（增加）”，常修饰终止性动词。 We wont go there any more.我们不再去那里了。 The baby watched and listened, and she cried no more.那个婴儿看着、听着，不再哭了。 2) no longer = not.any longer表示时间上“不再（延长）”，常修饰延续性动词。 He no longer lives here. 他不再住在这儿了。 You cant stay here any longer.你不能再留在这儿了。5. wear & put on & have on & dress 1) wear是“穿着”“戴着”的意思，强调状态。常用一般现在时表示经常状态，用进行时态表示 暂时状态。 wear还可用来表示佩戴手表、首饰、徽章、花儿的“佩”或“戴”以及留头发，胡须的“留”。 2) put on是“穿上”“戴上”，强调动作，是终止性动词短语，不能跟表示一段时间的状语连用。 3) have on意为“穿着”“戴着”，与wear同义，指穿的状态，其后可以接表示衣服、帽子、鞋 子的名词。have on不用于进行时态。 4) dress “使.穿着，装扮，打扮”dress sb/ dress sb in +衣服。 dress后面不能直接跟衣服。Exercise 2: 1.

What does your friend look like? He is short and thin. He has short, black hair. She is of medium build. 【拓展】be like 像一样 ，指品德、相貌等像（指人的个性特征） 如果询问人的性格、人品时，多用What be(am/is/are)like? E.g. Whats he like? 他是个什么样的人呢？ Hes friendly and kind. 他友好善良。 Exercise 4: 1. What do you look like? Im _.

He is of medium build. = He has a medium build. 2) build 作动词意为“建造，建设，建立”。 E.g. We are building a house. 【解析2】表示“某人长着或留着发”时，则只能用has/have 其构成为： “主语 have/has hair”。 E.g. He has short hair. 五、语法总结1. 形容词的顺序一般与被修饰形容词关系密切的形容词靠近名词; 如果几个形容词的重要性差不多, 可参照下表：限定词+数量词(序数词在前, 基数词在后)+ 描绘性状形容词+大小、长短、高低等形体+名词 规则：限定描绘大长高，形状年龄和新老；颜色国籍跟材料，作用类别往后靠。如: those+three+beautiful+large+square 新旧+颜色+国籍+材料+名词 (口诀：新颜国木) 如: old+brown+wood+table She has short curly blonde hair.Exercise 5: They have got such a _ table. A. round wooden brown B. round brown wooden C. brown round wooden2. 现在进行时表将来表示按计划、安排将要发生的动作，常跟tomorrow, soon等表示将来的时间状语。能用这种结构表示将来的动词往往是
