初二英语下册复习备课
Unit 1 第一课时
英语动词
可以分为四类:实义动词(或称行为动词)连系动词、情态动词以及助动词。
一、行为动词(它含有实在的意义(又叫实义动词),表示动作或状态,在句中可以单
独作谓语)
行为动词又分为及物动词和不及物动词,及物动词后面必须加宾语,意义才完整,不及物动词后面不能直接带宾语,常需要在宾语前加介词才能带宾语(look at (for, after), get to (on), hear of, hear from, point to (at), worry about, take care of ,play with, think about等)We study English very hard. She has a book in her hand. The sun rises in the east.
注意行为动词的几种变化形式原形enjoy第三人称单数 enjoys过去式enjoyed现在分词enjoying
二.连系动词(本身有一定词义,但不能独立作谓语,必须与表语一起构成谓语)
常见的连系动词有:be + adj. / n.是,在become + n. /adj. 变成turn + adj. 变得
get + adj.变得grow + adj. 长得
keep + adj保持着feel + adj感到look + adj看上去seem + adj./n看起来好象smell + adj.闻起来fall asleep 入睡
My parents are both farmers. The milk tastes terrible. The song sounds good.
第二课时
三.情态动词(本身有词义,但不能独立作谓语,只能和主要动词一起构成谓语,表示说话者的语气和情态,情态动词没有人称和数的变化)
Can you sing the English song? Everyone must get to school on time.
1.can:能,会表示能力,
2.may:可以,可能,或许may be 可能请区别maybe副词可能
3.must:必须,表示肯定的猜测must be 准是,一定是
4.could: 比can语气更委婉,客气,并不表示过去时。
5.must 表示说话人的主观看法,have to 表示外界客观愿望,不得不。
如:⑴Her mother is ill. She has to stay at home and take care of her. ⑵You must look after your clothes.
7.should 表示"应当,应该",与疑问词连用表意外,惊奇。What should I do? 我该怎么办呢?
四、助动词(本身无词义,不能独立作谓语,必须和主要动词构成谓语,表示疑问,否定,时态或其它语法形式)助动词有do, does, did, have, has, will, would等
*动词不定式形式:to +动词原形特点:1.无人称和数的变化。 2.在句中不能作谓语。 3.可以有自己的宾语或状语,构成不定式短语。
1. 使役动词: let, make 感观动词: see, hear, watch, feel, notice之后必须使用省略to的动词不定式。
如:⑴Nothing could make him get angry.⑵I often hear her sing in the morning.
2.It 作形式主语,可用to do 作真正的主语。如:⑴It took me half an hour to finish the work.
⑵It's bad for you to read in bed.⑶It's very kind of you to help me.
记住一些特殊结构:⑴Would like/love to do 想要做⑵Why not do ? 为什么不做⑶Help sb.(to)do sth. 帮助某人做某事4)too...to do sth. 太...以致不能...
(5)can't wait to do sth. 等不及做某事,迫不及待做某事(6)stop doing sth. 停止做某
事stop to do sth. 停下来开始做某事
Unit 2 第三课时
动词的时态:
(一)时态概述:作谓语的动词用来表示动作(情况)发生时间的各种形式称为时态,英语中的时态,就是通过特殊的动词词尾或加一些相关的助动词be, have(has)等,用来表示动作或事件发生的不同时间和方面。eg: He reads newspapers every day. He read the newspaper yesterday. He is
going to read the newspaper tomorrow.
(二)一般现在时: 1. 动词变化:一般现在时主要用动词原形表示,但第三人称单数后要加词尾-s,另外be和have有特殊的人称形式。
在加词尾-s时要注意:
读音:
2. 一般现在时主要表示:
(1)经常性或习惯性的动作,常与这样的时间状语连用:always, often, usually, sometimes 等eg: We always help each other. It often snows in winter. I get up early every morning. (2)表示主语现在的特征、性格、能力等。eg: He loves sports. Jane is an outgoing girl. Tom and Tim both have medium height.
