2、态 动词过程中体验英语的生动趣味性，引导学生提高对英语学 习的求知欲。三、教学重难点教学重点：学会运用情态动词can (cou I d), must, may, might,shaI I, shouId, ought to , wiI I (wouId),dare, need, have to等的用法以及各个相近情态动词间的区分.教学难点: 各个情态动词的用法区分.You needn t have your blood pressure taken tomorrow.3.过去时NEED的过去式仍然是NEED。1）过去时间由一过去时间状语 表示He need not come yesterday

3、. 2）过去时间由另一过去 时动词表示。 Al I he need do was to i nqu i re. It was c I ear that he need never troub I e to get up at seven aga i n. I told him he needn t be in a terr ible fix. 注：表示过 去的NEED常用于间接引语中。（本条可参照must的用法）三、NEED与虚拟语气1）NEED用于虚拟条件句（本条可参照虚拟条件句的构成及用法。）If money were use I ess, we need not struggle for

4、 it. If you had been carefuI enough, you need not have suffered. 注： 本条 用法较为少见。2）NEED单独使用：NEEDN T HAVE DONE （本条可参照 SHOULDN T HAVE DONE 的用法。）You need not have worried. 注：NEED HAVE DONE的形式较为少见Need you have scoIded him so severe Iy for hi s bad work? He had done h i s best.（否定意味）He need have gone and se

6、e seen much of the world, for he is just a I itt Ie boy. He must have seen much of the wor Id, for he has been traveI ing so widely.五、NEED与问句1）反意疑问句的构成You needn t go, need you? 2）答句的构成Need he go?Yes, he must/hasto/needs to. No, he needn t.（本条可参照must的用法）六、情态动词NEED与实义动词NEED 1）使用范围作为实义动词的NEED有人称、数和时态的变

7、化，使用范围更 为广泛，不受句子类型和时态的限制。在肯定句、过去时和 将来时的句子中，一般使用作为实义动词的NEED。He needs to see a doctor stra ightaway.（“匕处 needs to 不能换做need,因为本句是肯定句）Wi I I he need to start ear I ier? 注：NEED TO BE DONE与NEED DOING可以互换，后者更为常用（这 里的NEED均为实义动词）。2）含义差别NEEDN T HAVE DONE 与 DIDN T NEED TO DO 表示“不必要” 的时候，在意义上有所差别，前者表示“本不必做 ”， 实

8、际上已经做了（NEED为情态动词）；后者单纯地表示“不必 做 ” （NEED为实义动词）。第三篇：情态动词教案情态动词1.概念：情态动词：表示说话者的某些观点或态度的词语. 如“能”，“或许”，“必须”，“需要”，“应该” 等.2.情态动词主要有：can, may, must, need, shouId, 这些情态动词后面+动词原形.3.用法can （1）表示能力，意为“能，会”.如：eg: I can p I ay basketba I I. 我会打篮球.Can you p I ay basketba I I ?你会打篮球吗？ Yes, I can. / No, I can t.是的，我会.

19、t, may, might, shaI I, shouId, ought to , wiI I (wouId),dare, need, have to (板书)我们这节课主要来归纳下它的用法1、本身具有一定词意，但不能单独作谓语。为什么说情态 动词不能单独作谓语呢？谓语是对主语动作或状态的陈述或说明，指出“做什 么” “是什么”或是“怎么样”情态动词用在行为动词前， 表示说话人对这一动作或状态的看法或主观设想。(举例： i can wash cIothes)2、无人称和数的变化We must stay here.我们必须待在这儿。He must stay here. 他必须待在这儿。3、情态动

31、事，一般只用can,而不用couldo 如：Can Cou I d I come i n?我可以进来吗 “Could CanI use your pen? ” “Yes,of course you can. ”C. can和cou I d表推测对现在或将来的推测，两者均可用，但can通常只用于否定 句或疑问句中，一般不用于肯定句，而could则可用于肯定 句、否定句和疑问句；对过去的推测，应在can, cou I d之后 接动词的完成式，且此时can仍只用于否定句或疑问句，不 用于肯定句；而could则可用于各种句型。如：Can Cou I d th i s be true?这能是真的吗Wi
