情态动词的用法语法必修三第二单元

情态动词551、重温情态动词的语法特征。2、掌握情态动词oughtto,oughtnotto,haveto,don'thaveto,mustn't,needn't.3、懂得区分should和oughtto,区分needn't和mustn't。1、重温情态动词的语法特征。56情态动词是高考的必考知识点，看似简单，但准确运用就没那么容易了。所以讲授情态动词时，就是要把那些似是而非的内容搞清楚。在必修三第一单元，已经把情态动词的语法特征讲述了一遍。本单元是必修三第二单元。首先重温第一单元的情态动词的语法特征，再进一步通过should引出oughtto,并区分它们用法上的不同。然后又通过must引出haveto,也把它们用法上的不同区分开来。接着，学习否定形式：oughtnotto,don'thaveto,mustn't,needn't.并区分mustn't和needn't的用法。

最后，通过练习来巩固所学的知识。

情态动词是高考的必考知识点，看似简单，但准57情态动词的语法特征：1.情态动词有一定的意义，表示或暗示某种情绪或态度，表示可能、建议、愿望、必要、允许、能力等。但只表示期待或估计某事的发生，不能表示正在发生或已经发生的事情。2.情态动词不能独立使用，必须和实义动词一起构成谓语。3.情态动词没有人称和数的变化，即不随主语的不同而变化。4.有些情态动词,如can、will也有一般式和过去式的变化。但情态动词的“时态”形式并不是时间区别的主要标志。不少情况下,情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。知识点回顾：情态动词的语法特征：知识点回顾：581.—______itbeLiPingwhobroketheglass?—No.It______beWuDongwhodidit.
