* 常用的情态动词有:can, could, may, might, must, shall, should, will,

would这九大情态动词;其他的还有ought to, need, dare 等。

一、九大情态动词的时态关系:

1. 现在式 can --过去式 could

2. 现在式 may --过去式 might

3. 现在式 shall --过去式 should

4. 现在式 will --过去式 would

5. 现在式 must --过去式 must (常用had to来代替)

二、情态动词表示“可能”或“**”

(can, could, will, would, shall, should, must, ought to)

(1)can 和 could 用于表示“可能”或“**”:

1. he can't be at home. (否定句)他不可能在家。

2. can the news be true ? 将情态动词 can 置于主语 the news 前就成疑问句)这消息可能是真的吗?

3. anybody can make mistake. (只表示理论上的可能性)任何人都可能犯错误。

(2)may 和 might 用于表示“事实上的可能性”或“**”:

1. it may rain tomorrow. (表示可能会发生) 明天可能会下雨。

2. it may snow later this afternoon. (表示**)今天下午可能会下雪。

4)may 和 might 用于表示“许可”(口语中多用 can )

1. you may take a walk. (表示给予许可)你可以散散步。

2. you might read the story for me. (比may更婉转)是否请给我读一读这故事。

3. may i make a suggestion?我可以提个建议吗?

4. might i take a look of your work?我看看您的大作行吗?

5. students may not make noise in the library. (may not 表示不许可或禁止)学生不得在图书馆里吵闹。

6. if i may say so, you are not right. (用于条件句,表示请求)你是不对的,如果我可以这么说的话。

(5)must 用于表示“禁止”,“不准”:

1. cars must not be parked here. (must not表示不许可)此地不准停车。

2. all of you mustn't fishing in the pool. (must not 语气方面比 may not 更强) 你们不准在池里钓鱼。

典型例题解析】

例1.—what a beautiful sweater!

—how much did you __for it?

a.take b. cost c. pay d. spend

解析此题考查花费的区别。此题主语是“人”,并且pay常与for连用,意为“为……付款”,故此题选c。

答案 c例2.you shouldn’t __here. the baby __

a. play; sleeping b. to play; is sleeping c. plays, sleeps d. play; is sleeping

正解 d错因分析此题做错的原因是没有熟练掌握情态动词的用法,情态动词后面给动词原形。在第一个句子中should是情态动词,后面应用动词原形,所以排除b、c选项,根据句意第二个句子应用现在进行时态,结构是am/ is /are+ v-ing形式。故选d。

例3.—could you please __me your bike?

—sorry, amy __it an hour ago.

a. lend, borrow b. lend, borrowed c. borrow; lent d. borrow; lend

正解 b错因分析此题所错的原因是没有掌握borrow和lend的用法。borrow和lend都有“借”的意思,borrow是“借入”的意思;lend是“借出”的意思。此外相应的句型也不一样,borrow……from……,lend sth.

to sb.或lend sb. sth。

第二个句子。根据an hour ago可以确定是一般过去时态。

例4.(2024年遵义) a: what __under your bed, langlang?

b: oh, where are my basketball shoes, mom?

a. do you do b. are you doing c. did you do

析】此题主要时态。a项是一般现在时态,b项是现在进行时态,c项是过去时态。从答语“他在找他的篮球运动鞋”来看,可以知道问句应该是:现在进行时态。故此题选b。

答案 bi.根据句意及首字母提示补全单词。

1.this work is too difficult.it doesn’t f me.

2.the school things i pens,pencils,erasers and books.

3.if you h**e a p ,you can ask me for help.

4.i’m very u and don’t know what to do.

4.johnwrite) something when igo) to see him.
