二、重难点讲解
1.Six years ago, Mike could read and draw, but he could not write.
六年前,迈克会阅读和画画,但是他不会写字。
解析:(1) could是情态动词 can的过去式,用于谈论某人过去拥有的能力,其后接动词原形。
它的否定形式是在 could后面加上not,可以缩写成couldn’t。
(2) could还可以表示许可或同意,指委婉客气地提出问题或陈述看法。
【例句】(1) Could you speak English then? 那时候你会说英语吗?
(2) Could I borrow your computer? 我可以借用你的电脑吗?
【练习】单项选择。
( )(1) Little Tom could not _________the piano last year.

( )(2) Su Hai _________look after herself when she was a child.
A. cannot B. can C. could
2.Twenty years ago, Mr Brown wrote letters to his friends.
二十年前,布朗先生写信给他的朋友们。
解析:wrote 是 write的过去式形式。write(a letter/letters) to sb意为“写信给某人”
相当于write sb a letter/letters。
【例句】George wrote some letters to his friends.=George wrote his friends some letters.
乔治写了一些信给他的朋友们。
【练习】单项选择。
( ) Su Hai’s mother _________a letter to her friend last weekend.
A. writes B. wrote C. writing
3.He used the telephone at home and in the office to call people.
他在家以及办公室里用电话打电话给人们。
解析:used是 use的过去式形式。use…to do sth意为“用……去做某事”,带 to的动词不定式在此处表示目的。
【例句】John’s little sister can use a painting brush to draw pictures.
约翰的小妹妹会用画笔画画。
【练习】用所给词的适当形式填空。
Mike uses the computer _________(write) music.
4.She bought things from shops. 她(过去)从商店买东西。
解析:bought 是 buy的过去式形式。buy …from …意为“从……买……”。
表示“买某物给某人”则用短语buy sth for sb,相当于buy sb sth。
【例句】(1) Mrs Johnson’s son often buys toys from the toy shop.
约翰逊太太的儿子经常从玩具店买玩具。
(2) Mr Brown wants to buy a Christmas tree for Mike.
=Mr Brown wants to buy Mike a Christmas tree.

5.The lesson goes on, but Bobby is still looking out of the window.

解析:look out of ...意为“朝……外看”。其他常见的与 look 搭配的短语:
look for 意为“寻找”, look after意为“照顾”, look out意为“小心”, look around 意为“环顾四周”。
【例句】That dog is looking out of the door. 那只狗正在朝门外看。
【练习】单项选择。
( ) Mr Green _________ the window to enjoy the beautiful scenery.
A. looked out of B. looked after C. looked for
6.Miss Fox gets angry. 狐狸老师变得生气。
解析:句中的 get 是系动词,意为“变得,成为”,常与形容词连用,表示一种渐渐变化的过程。
【例句】We have to go now. It’s getting late. 我们现在得走了。天色越来越晚了。
【练习】根据中文提示完成句子。
夏天天气变得炎热起来了。
The weather _________ _________in summer.
7.Miss Fox waits for the answer. 狐狸老师在等待答案。
解析:wait for …意为“等待……”,后接名词或代词作宾语。
【例句】We’re waiting for the metro to the museum.

【练习】根据所给中文提示填空。
Is the teacher _________ _________ (等待) you in the office?
三、易错易混全解
1.易混淆动词 look, see, watch 与 read 的用法。
【例题】单项选择。
( ) My father _________ newspapers for news ten years ago.
A. watched B. saw C. looked D. read
点拨:look 强调“看”的动作,可以单独使用,用来引起对方的注意,如果后面接宾语,则要与at连用;see强调“看”的结果,表示看见、看到;watch 表示注视、观看,常用于表示看电视、看电影、观看足球之类的体育运动等;read表示阅读,常用于表示看书、看报纸等。此题设空处后为newspapers,应该用read 来搭配,故选D。
2.易混淆 with 与 use 的用法。
【例题】选词填空。
(1) I cut the paper _________ (with/use) the knife.
(2) You can _________ (with/use) my mobile phone to call your mother.
点拨:with 和 use 都有“用”的意思,但是两者用法不同。with 是介词,表示一种方式,在句中作状语;use 是动词,在句中作谓语。
第(1)小题,句中已经有谓语动词cut,设空处所填内容应与后面的 the knife一起作状语,故填 with。第(2)小题,句子缺少谓语动词,故填 use。
