二、语法点拨。

情态动词。1. 情态动词的基本用法

情态动词本身有一定的意义,但它必须和动词一起构成谓语。情态动词can, could, may, must, h**e to, will, shall, should, would, need等没有人称和数的变化(h**e to除外),后接动词原形。

① can / could 表示“能力”、“客观可能性”、“请求”和“允许”;用在否定句、疑问句或感叹句中,还可表示惊异、怀疑、不相信的态度;在一般疑问句第一人称中,表示“征询对方许可”(用could比用can语气更加委婉,但答语必须用can);在一般疑问句第二人称中,can和could往往用来表示说话人的请求或征询意见。 如:--could you help me carry the bag?

-yes, i can.

② may用于句型“may i ..时,表示征询对方许可。-may i watch tv now? -no, you can’t.

must意为“必须、应当”,表示“义务、命令”;肯定用must,否定用needn’t或don’t h**e to,(mustn’t,则表示“禁止”)。must i finish the work today? -no, you needn’t (don’t h**e to).

need用于否定句或疑问句-need i finish the work today? –yes, you must. /no, you needn’t

⑤ shall 表示说话人征求对方的意见或向对方提议;还可表示命令、警告、允诺或威胁。

⑥ should 意为“应该”,表示义务、责任,可用于各种人称。 如:you should be polite to the old.

⑦ will用于疑问句,向对方提出请求或建议will you please not drop your shoes next time?

h**e to“不得不”,着重客观需要,可用于多种时态;而must强调主**法,没有时态变化。

2. 情态动词must, may, might, can, could等表示“推测”

must, may, might, can, could的推测程度由强到弱的顺序是:must, can, could, may, might

① must表示有把握的推测,意为“一定是;肯定是”,只用于肯定句中,表示对现在的推测,若表达相应的否定意义,则用can’t或couldn’t

② can表示惊异、怀疑或不相信的推测,多用于否定句或疑问句中,常用来表示对现在或将来事实的推测。如:he can’t be at home now. 他现在不可能在家。

③ may表示把握性不大的推测,意为“可能;也许”,常用于肯定句中。如:

don’t play with the fire. you may burn yourself. 不要玩火, 你可能会烧伤自己。

④ could和might表示推测时,语气比较委婉。如:he may / might / could be very thirsty.

一般过去时

一般过去时中通常用以下的时间状语:

yesterday; last night; a month ago; yesterday afternoon; last week; ten years ago

一般过去时的构成:规则动词后加‘- ed’

1) 大部分动词后加 ‘-ed’ walk → walked 2) 以‘e’结尾的动词后加‘-d’ live → lived

3) 以辅音字母加‘-y’ 结尾的动词,把‘y’ 变成‘i’ 加‘-ed’ try → tried

4) 以辅音字母结尾,重读闭音节的动词,双写最后一个辅音字母加‘-ed’ stop → stopped

1) 去年你在学校篮球队吗? 不,我堂弟在。__you at school basketball team last year?

no, imy cousin __in.

2) 你是什么时候遇见他的?上周you __him? i __him last week.

3) 昨天谁生病了? 吉姆ill yesterday? jim

4) 昨天米莉没有做数学家庭作业。 millieher maths homework.

重点句型】1. i don’t know what to wear today, hobo. 霍波,我不知道今天穿什么。

句中的to加动词原形被称为“动词不定式”,可以和疑问词what, when, how, when, where等连用,构成动词不定式短语。如:

i don’t know how to get to the post office. where to go is a big problem.

can you tell me when to watch the film? 你能告诉我什么时候看这部电影吗?
