1、第 33 天 情态动词(二)学习要点 情态动词 will，shall，would，should，need 的用法。家教点窍 一、should 表示义务或责任。shall 表示说话人的决心、意图，在疑问句中表示征求对方的意见。will，would 分别表示现在和过去的意志、决心和愿望，当用于第二人称作主语的疑问句中，表示征求对方的意见。二、need 作情态动词主要用于否定句和疑问句，注意和 need 作行为动词的区别。典型例题 例 1 选择填空。I like chocolates,and after dinner have some of them.(A)used to would (B)wou

2、ldwould (C)wouldused to (D)is used toused to 评析 used to和 would都表示的习惯动作。used to可以表示过去持续的行为、情况或状态，而 would则不可。like表示过去持续的行为，所以用 used to，而不能用 would。另外 used to含有“过去如此，现在不再如此”之意。答案选(A)。例 2 选择填空。You to be more careful if you want to pass the examination.(A)should (B)can (C)must (D)ought 评析 情态动词应该接原形动词，排除(A

3、)、(B)、(C)。答案选(D)。例 3 选择填空。You dont to go there if you have no time.(A)need (B)want (C)must (D)should 评析(C)、(D)后面不接 to 的不定式，(B)意义不合。need既可以作情态动词也可以作实义动词。当它作实义动词时，否定结构为 dont need to。答案选(A)。强化训练 一、选择填空。1.“Who it be that knocked at the door?”The old man wondered.(A)can (B)may (C)will (D)must 2.We think
