语法冲关 语言规则全理清
情境导入
Last night,I stayed up till 11 o’clock to write my English reading report which has to be handed in this morning.
Because I was not able to write an excellent report,I asked my cousin,who is good at English writing,to do me a favour.Today,however,my English teacher told me I needn’t have handed in the report so urgently.She asked me whether I wrote the English report by myself.I told her the truth for I dare not tell lies. Surprisingly,she didn’t get angry with me.Instead,she said that I had better do it on my own whatever the result.From then on,I knew I must do my homework by myself whether it’s easy or difficult.
【语法感悟】
(1)以上句子当中的加黑部分都是　　　　　　　　　　,其后所接的动词应用　　　　　　　　　　。
(2)情态动词变否定式时,要在其后直接加　　　　　。
情态动词
动词原形
not
语法精讲
一、基本特征
【先感悟】
①She can speak fluent English though she is six.
尽管她才6岁,但她会说流利的英语。
②They had to finish the task by ten.
他们必须在十点前完成任务。
③The baby girl is able to stand up and walk.
这个女婴能站起来走路了。
④We need to take a different way to the problem.
我们需要采用另一种方法来解决这一问题。
【善归纳】
情态动词有一定的词义,不能单独作谓语,需和　　　　　　或_________　　　　　　一起作谓语; 构成否定句时,在其后加　　　　　　。
实义动词
系动词
not
二、基本用法
1.be able to的用法
【先感悟】
①It took me a long time before I was able to fully appreciate what they had done for me.
我过了好久才能完全理解他们为我做的事情。
②Tough though the task was,we were able to finish it ahead of time and therefore we were praised for it.
尽管这项任务很难,但我们还是提前完成了,并因此得到了表扬。
③If we keep trying,we will be able to achieve our goals.
如果我们不断尝试,我们将能实现我们的目标。
④I’m sorry I haven’t been able to answer your letter in time.
很抱歉我没能及时给你回信。
⑤By the time she was eight,she could read Greek and Latin.
她8岁就会读希腊文和拉丁文了。
⑥You can’t stop people saying what they think.
人们怎么想就会怎么说,你阻止不了。
【善归纳】
be able to表示“经过努力而成功地做成某事”,有　　　 　　　的变化,不能与　　　　　　连用。can与be able to的区别是:be able to 有更多的时态形式,can只有一般现在时和一般过去时;was/were able to表示“过去成功做成了某事”,相当于succeeded in doing sth.,而　　　　　　仅表示过去客观上有某种能力,不说明实施该能力后的结果。
人称和时态
can
could
2.need的用法
【先感悟】
①—Need I finish the work today
—Yes,you must/have to./No,you needn’t.
——我需要今天干完这活吗
——是的,你必须干完。/不用,你不必干完。
②There’s plenty of time.You needn’t drive so fast.
时间很充足,你不必开这么快。
③The bike needs repairing.
=The bike needs to be repaired.
这辆自行车需要修理。
【善归纳】
need作情态动词时,后跟　　　　　　,表示“需要,有必要”,无人称和数的变化,多用于否定句、　　　　　　或条件句中;由need引起的一般疑问句的肯定回答常用must或have to,否定回答常用　　 　 　　　;need作实义动词时,后可接名词、动词-ing形式、不定式等,有人称、时态和数的变化。
动词原形
疑问句
needn’t或don’t have to
3.have to的用法
【先感悟】
①You have to work hard nowadays to make a living.
如今,为了生活,你就得努力工作。
②You must do what I tell you.
你必须按照我告诉你的去做。
③We had to be there at ten.
我们得在十点钟到达那里。
④I have to go to the dentist soon.
我得赶快到牙科医生那里去。
【善归纳】
have to表示“必须,不得不”,强调　　　　　　,否定形式为don’t have to,表示“不必”;而must表示“必须”,只有现在时形式,而have to能用于更多时态(将来时和过去时)。
客观需要
4.dare的用法
【先感悟】
①I dare not walk through the woods at night.
夜间我不敢在小树林里走。
②The children don’t dare (to) make a sound while their parents are sleeping.
孩子们在父母睡觉时不敢弄出一点声音。
③Does he dare (to) tell you what he has done

【善归纳】
dare既可以作实义动词,也可以作情态动词,作情态动词时多用于　　　　　　、疑问句、条件状语从句及表示怀疑的　　　　　　从句中,表示“敢……”;dare也可以作实义动词,在否定句、疑问句中时,不定式符号to可以　　　　　　。
否定句
名词性
省略
5.had better的用法
【先感悟】
①You’d better get there before it gets dark.
你最好天黑前到那里。
②We’d better not talk so loudly.
