小学英语情态动词知识点及练习

情态动词【知识要点】:情态动词(Modal verbs)本身有一定的词义, 表示语气的单词。
但是不能独立作谓语, 只能和动词原形一起构成谓语。
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。
情态动词虽然数量不多, 但用途广泛, 主要有下列: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not.情态动词无人称和数的变化, 情态动词后面跟的动词须用原形, 否定式构成是在情态动词后面加 "not"。
疑问形式是将情态动词提至主语前。
个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去, 现在或将来。
情态动词属非及物动词, 故没有被动语态。
【典型例题】:【专题一】:can和could的用法【例1】Can you lift this heavy box?(体力)【解析】表示能力(体力、知识、技能)【练习】1.Mary speak three languages.(知识)2... yo.skate?(技能)此时可用be able to代替。
Can只有一般现在时和一般过去式;而be able to 则有更多的时态。
I’ll not be able to come this afternoon.当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。
【例2】-----Can I go now?----.Yes.yo.can..No.yo.can’t.【解析】表示请求和允许。
此时可与may互换。
在疑问句中还可用could,might 代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
【练习】---- I come to see you tomorrow?---.Yes.yo.....----No.yo..../I’.afrai.not.【例3】Can this be true?【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。
