Part 2　Grammar
语法冲关 语言规则全理清
情景导入
情态动词(1)
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
1.情态动词有一定的词义,不能单独作谓语,需和实义动词或系动词一起作谓语。
She can speak English though she is six.
尽管她才6岁,但她会说英语。
2.情态动词一般无人称和数的变化,个别情态动词有现在时和过去时两种时态变化。
They had to finish the task by ten.
他们必须在十点前完成任务。
3.构成否定句时,not放在其后面。
The young man can’t carry the big stone.
这个年轻人搬不动那块大石头。
4.情态动词后接动词原形。
You have to finish your work today.
你必须在今天完成你的工作。
二、基本用法
1.be able to的用法
(1)be able to表示“经过努力而成功地做成某事”,有人称和时态的变化,不能与can连用。
It 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。
Tough 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。
If 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。
(2)be able to与can/could的区别
①be able to有更多的时态形式,can只有一般现在时和一般过去时。
Will you be able to come tomorrow
你明天能来吗
I’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。
Babies could swim when they were born.
婴儿们刚生下来时会游泳。
②was/were able to表示“过去成功做成了某事”,相当于succeeded in doing sth.。could仅表示客观上有某种能力,不说明实施该能力后的结果。
Without his hard work,he was not able to get good grades.
如果他没有努力学习,他是不可能取得好成绩的。
By 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。
2.need的用法
(1)need作情态动词时,后跟动词原形,表示“需要,有必要”,无人称和数的变化,多用于疑问句、否定句或条件句中。
—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。
There’s plenty of time.You needn’t drive so fast.
时间很充足,你不必开这么快。
注意:由need引起的一般疑问句,肯定回答常用must或have to;否定回答常用needn’t。
(2)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。
The bike needs repairing.
=The bike needs to be repaired.
这辆自行车需要修理。
3.have to的用法
(1)have to表示“必须,不得不”,强调客观需要。否定形式为don’t have to,表示“不必”。
You have to work hard nowadays to make a living.
如今,为了生活,你就得努力工作。
(2)must也表示“必须”,但着重表示说话人的主观看法。
You must do what I tell you.
你必须按照我告诉你的去做。
(3)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)。
We had to be there at ten.
我们得在十点钟到达那里。
I have to go to the dentist soon.
我得尽快到牙科医生那里去。
4.dare的用法
(1)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、否定句、条件状语从句以及表示怀疑的名词性从句中,表示“敢……”。
I dare not walk through the woods at night.
夜间我不敢在小树林里走。
(2)dare作实义动词时,在否定句、疑问句中,不定式符号to也可以省略。
The 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。
Does he dare (to) tell you what he has done
他敢告诉你们他所做的事情吗
5.had better的用法
had better后跟动词原形,表示“最好……”,其否定式在had better后加not。
You’d better get there before it gets dark.
你最好天黑前到那里。
We’d better not talk so loudly.
我们最好不要这么大声说话。
