新概念英语第一册126

一、第125-126课的重要句型或语法内容 　　1、情态动词 　　本课侧重的是情态动词must和need的用法，同时对比了have to的用法。其中，需要注意的是must与have to的区别以及must的否定表达。如： 　　1)Do you have to water it now? I'm afraid I must. 　　问句采用have to，强调的是客观上是否不得不，而回答时采用must，强调是自己主观认为必须。 　　2)That means you don't need to water the garden. 　　句中的don't need to用作must的否定表达。 　　二、课文主要语言点 　　Can't you come in and have tea now, Peter? 　　Not yet. I must water the garden first. 　　1)Can't you...?，反问句，往往用来提出建议或质疑。 2)not yet，还没有、还没好 3)water the garden，给花园浇水。water在此用作动词，表示浇水的意思，如water the flowers，浇花。 　　Do you have to water it now? I'm afraid I must. 注意have to与must的区别：have to强调是出于客观原因“不得不”做某事，而must则偏重的是主观上认为“必须”。另外，have to不是情态动词，就是一般的动词短语，之所以会放到情态动词里一起讲解，只是因为它可以表“必须”。 　　Look at it! It's terribly dry. terribly是terrible(可怕的)的副词，但在此处相当于very，表示非常、很。 　　What a nuisance! 1)nuisance，讨厌的东西或人。 2)注意复习what和how引导的感叹句。 　　Last summer it was very dry, too. 　　Don't you remember? I had to water it every day. 　　1)因为句中用了last summer，所以系动词be要用一般过去时was。 2)Don't you...?，反问句，意为“难道你...”。 3)可提问学生为什么句中的have to要用一般过去时had to的形式(因为本句话说的还是去年夏天的事情)。 　　Well, I'll have tea by myself. by oneself，独自。 　　That was quick! 可提问学生为什么这句话要用一般过去时(因为该句话说的是Peter刚才浇水的动作很快，是过去的动作)。 　　Have you finished already? Yes. 注意句中的already的位置。一般情况下，already要放在助动词后面、实义动词前面，即：Have you already finished? 本句话把already放到句末，起到一定的强调作用。 　　Look out of the window. 注意对比look out of(从里往外看)和look through(从外往里看)的区别。 　　That meas you don't need to water the garden. 1)mean用作动词，表示“意思是，意味着”。 2)mean后面接的是宾语从句you don't need to water the garden，省略了连接词that。 3)don't need to，是need作为实义动词的否定表达，也是must的否定表达。另外一种表达形式是needn't，此时的need用作了情态动词。 　　That was a pleasant surprise. 1)可提问学生为什么本句动词要采用一般过去时(因为本句话说的是刚才发生的事情，即Peter不用给花园浇水了)。 2)a pleasant surprise，意外的惊喜。 　　It means I can have tea, instead. 1)本句话的结构与That means you don't need to water the garden是一样的，mean后面接的是省略that的宾语从句。 2)instead，用作副词，表示“反而”。注意instead of，是介词短语，表示“代替，反而”。 　　三、双课补充内容 　　继续操练have to、must和don't need to的用法。
