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。
