Ⅱ.热点语法:
情态动词
情态动词ought(not)to/(don’t)haveto/mustn’t/needn’t的用法归纳:
1.oughtto与should同义,意为“应该;应当”,表示责任或义务;意为“该;一定”,作推测性的结论。
eg:
Weoughttostartatonce.
Thatoughttobeenoughfoodforallofus.
(1)否定式为oughtn’ttoeg:
Theyoughtn’ttolettheirdogrunontheroad.
(2)变为一般疑问句时,ought提到句首,回答时oughtto,to可省略。
eg:
—Oughtyoutofinishyourhomeworkbeforeplayingbasketball?
—Yes,Iought(to).
(3)反意疑问句的构成:
根据前肯定后否定的原则;反问时省略to。
eg:
Theyoughtn’ttolettheirdogrunontheroad,oughtthey?
2.haveto表示义务和责任时,意为“必须;不得不”,强调客观因素的影响;还可表示劝告或建议;也可指得出合乎逻辑的结论。
eg:
Ihavetotypelettersandanswerthephone.
Yousimplyhavetogetanewjob.
Eventhoughtheworkispuzzling,therehastobeasolution.
(1)有人称和数的变化。
(2)适用于现在、过去和将来时。
(must只用于一般现在时)
(3)用don’t构成否定式;疑问句可用do或直接用have。
eg:
Youdon’thavetopayforafine.
Havewetomakeourownwaytotheconference?
=Dowehavetomakeourwaytotheconference?
(4)口语中可以用havegotto。
eg:
Youhavegottoputonmoreclothessinceitissocold.
3.must强调主观上认为必须做的事情,区别于haveto,意为“必须;应当”;还可用于表示推测,表示“一定;肯定”。
eg:
Hesaidthattheymustworkhard.
Hemustbeintheclassroomnow.
(1)无人称和数的变化;没有时态变化。
(2)否定式mustnot(mustn’t)表示“禁止;不准;不允许”。
eg:
Carsmustnotparkinfrontoftheentrance.
(3)表推测时的否定句和疑问句要用can代替。
eg:
Hemustn’tbeoutinsuchacoldnight.(×)
Hecan’tbeoutinsuchacoldnight.(√)
4.need意为“必须”,无时态、人称和数的变化。
构成一般疑问句时,把need提到主语前,肯定回答用must,否定回答用needn’t。
eg:
Needyougonow?
Yes,Imust./No,Ineedn’t.
Youneedn’tfinishthatworktoday.
注:
need可以作实意动词用,这时有人称、数和时态的变化;宾语需要用不定式。
