广州版初一上册英语Unit4形容词.doc

广州版初一上册Unit4同步教学目标:1、 巩固Unit 4重要单词、常考短语和句型的用法。2、 学会谈论一年中的四个季节，并能够正确运用形容词。教学重点、难点:1、 掌握Unit 4常用单词、短语和句型的用法。2、掌握形容词（形容词修饰名词、主系表结构及形容词在形式主语句型中）的用法。教学步骤：【课堂演练】一、朗读Unit 4新单词和短语，纠正学生的发音，并讲解其用法，然后听写。_二、课本内容讲解。三、Unit 4知识点梳理：1、【词义辨析】Australia是名词，“澳大利亚”；Australian作名词时表示“澳大利亚人”，复数形式为Australians，作形容词时为“澳大利亚的”。2、【词义辨析】watch sb. do sth.“看见某人做某事”，强调动作的整个过程；watch sb. doing sth. “看见某人正在做某事”，强调看见动作正在进行。类似watch用法的动词还有hear，see等。I watch him get on the bus. I watch her cleaning the classroom.3、【词语辨析】start doing sth.与start to do sth.都表示“开始做某事”，一般情况下两者可以互换，但以下情形中，要注意区别：（1）用动名词的情况：当谈论一项长期的习惯性的活动时 I start learning English.（2）用动词不定式的情况：在start本身为进行时态的时候；当start后接表示心理状态或精神活动的动词时；当主语是物不是人时Im starting to cook the dinner. Mary starts to guess what is in the bag. It starts to snow.4、I like summer best. = My favourite season is summer.5、have fun“过得愉快，玩得高兴”，可以用have a lot of fun / have lots of fun，相当于have a good time / enjoy oneself。fun是不可数名词，表示“娱乐，乐趣”。6、【词义辨析】spend, take, cost和pay都可以表示“花费”，但用法不同：（1）spend的主语必须是人， 常用于以下结构：spend time with sb.；spend time money on sth.；spend time money (in) doing sth.（2）cost的主语是物或某种活动，还可以表示“值”，常见用法有：sth. costs (sb.) 金钱，表示“某物花了（某人）多少钱”；(doing) sth. costs (sb.) 时间，表示“某物（做某事）花了（某人）多少时间”。例：A new computer costs a lot of money. Remembering these new words cost him a lot of time.（3）take后面常跟双宾语，常见用法有：It takes sb. 时间to do sth.表示“做某事花了某人多少时间”；doing sth. takes sb.时间，表示“做某事花了某人多少时间”。 例：It took them three years to build this road. Repairing this car took him the whole afternoon. （4）pay经常与for连用，表示“付钱（给某人）买”或“付的钱”。I have to pay them 20 pounds for this room each month. 7、【词语辨析】get, become, turn, grow与go在表示“变，变得”时用法有区别：(1) go通常表示由好变坏或由正常情况变成特殊情况。go bad / blind / mad / wrong变坏/变瞎/疯了/出毛病。 In hot weather，meat goes bad.。(2) become和get表示的变化可以是由好到坏，也可以是由坏到好，强调变化过程的完成。become better/worse更好/更糟；get richer and richer变得越来越富(3) grow有“逐渐变化”的含义，强调变化的过程。grow tall grow louder（声音）大起来 The girl grew thinner and thinner. (4) turn表示变为完全不同的事物，强调变化的结果。表示颜色变化时用turn。turn yellow变黄 turn gray变灰白 Leaves turn yellow in autumn.8、marry的用法：marry既可用作及物动词，也可用作不及物动词，意为结婚；嫁；娶；与.结婚等。常见用法如下：（1）marry sb表示嫁给某人；与.结婚。例如：John married Mary last week. （2）be / get married to sb表示与某人结婚。例如：Rose was / got married to a teacher. （3）marry作不及物动词时，往往用副词或介词短语来修饰。例如：She married very early.（4）marry不能与介词with 连用。例如：她和一位英国人结了婚。【误】She married with an Englishman.【正】She married an Englishman. 【正】She was / got married to an Englishman.9、take a trip = have a trip去旅行，类似的词组还有：take / have a rest take / have a walk = go for a walk take / have a look 10、go + v. ing构成的短语：go swimming go fishing go shopping go boating go skating go sightseeing11、have a picnic = go on a picnic go on holiday go to the beach12、make snowmen fly kites during the winter holidays during the day在白天at this time of year在每年的这个时候13、It is + adj. +for sb. to do sth.与It is + adj. + of sb. to do sth. 的区别：14、词义辨析：such as “比如”，常用来列举同类人或物中的几个例子；for example“例如，譬如”，表示举例说明，一般只列举同类人或物中的一个作为插入语，常用逗号与其他部分隔开。 I have many hobbies such as fishing and swimming.Many boys in our class, for example, John and Paul, are good at playing basketball.四、形容词用法讲解：形容词表示人或事物的性质、状态，一般放在它所修饰的名词之前作定语，或连系动词之后做表语。1、形容词作定语（1）大多数形容词作定语修饰名词时，其位置在被修饰的名词前面，说明名词的品质或特征。Shes a tall girl. Its a black and white cat.（2）修饰somebody, someone, something, anybody, anything, nobody, nothing等复合不定代词的形容词，作定语时要后置。I would like something cheap.
