34、ld 和ought to,区分neednt 和mustnt。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ought to,并区分它们用法上的不同。然后又通过must引出have to,也把它们用法上的不同区分开来。接着，学习否定形式：ought not to,dont have to,mustnt,neednt.并区分mustnt和neednt的用法。最后，通过练习来巩固所学的

35、知识。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：1._ it be Li Ping who broke the glass?No.It _ be

48、ises today?-No，You neednt.-我们必须今天交练习吗?-不，不必今天交。注意:didnt need to则常表示过去未做也勿须做的动作。这时候的need是实义动词。I didnt need to take a taxi；it is only five minutes walk to the station.到车站只须走五分钟，我不需要坐出租汽车。否定形式（二）3.have to 的否定形式是dont have to,相当于neednt。请注意时态。They dont have to buy a computer at present.他们目前没有必要买电脑。Mr.John
