Mrs Chen to work in your place. )

(2) 用在 suggest (propose), arrange, plan, decide, advise, order, demand, request, desire, insist 等表示“建议”、“要求”、“命令”、“决定”、“安排”、“计划”、“主张”的动词后面接的宾语从句中。这里的 should 也可以省略。

高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类:基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个:do, have和be;情态助动词有十三个:may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是,在协助主动词构成限定动词词组时,具有作用词的功能: 1)构成否定式: He didn't go and neither did she. The meeting might not start until 5 o'clock. 2)构成疑问式或附加疑问式: Must you leave right now? You have been learning French for 5 years, haven't you? 3)构成修辞倒装: Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4)代替限定动词词组: A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是,基本助动词本身没有词义,而情态助动词则有自己的词义,能表示说话人对有关动作或状态的看法,或表示主观设想: What have you been doing since? (构成完成进行体,本身无词义) I am afraid I must be going. (一定要) You may have read some account of the matter. (或许已经) 除此之外,情态助动词还有如下词法和句法特征: 1)除ought和used以外,其他情态动词后面只能接不带to的不定式。如果我们把ought

情态动词的用法 A. can; could; be able to Can 1. 表示“能力”(此时过去时是could) 2.表示许可、请求,“可以”。--Can/Could I go now? 3 表示推测, 把握很大,could也可表推测,把握比can小。 --Look! Someone is coming! Who can it be? --It can?t be him. He has gone to Paris.(不可能)/ He could be here soon. 他很快就来。 4 表示感情(惊异/不耐烦)“究竟,到底”(主要用于否定句,疑问句和感叹句中。) How can you be so foolish? What can it possibly be? 到底那是怎么一回事? They can?t be working at this time of day. 5 肯定句中客观存在的可能性。“有时会,偶尔” It can be quite windy there, especially in spring. Could 1.表示能力,can 的过去式,过去能够 Could you speak English then? 那时候你会说英语吗? 2. 请求允许(委婉语气)(问句的答语不用could,而用can,) Could [Can] I use your pen? ” “Yes, of course you can.”/ No, I?m afraid not. 3. 表示推测可能性(肯,否,疑) We could go there this summer. 今年夏天我们可能要去那儿。(将来可能性) You could be right, but I don?t think you are. 你可能是对的,但我并不认为你是对的。 4. could have done ①对过去推测,可能已经。。。②本来能够却没做,差点就 He can?t [couldn?t] have seen her there. 他不可能在那儿见到她。 He could have gone home. 他可能已回家了 He could have told her, but he didn?t choose to. 他本来可以告诉她的,但他却没有。 B. may 和might 1.表示允许﹑许可,might提问更委婉。 ---May/Might I watch TV after supper? ---Yes, you may./ Yes, please./ Certainly. ---No, you mustn't. / No, you may not. / No, you can?t./No, you?d better not. 2. 表示推测,有“或许”、“可能”的意思。might把握更小。疑问句用can/ could. ?He may/might be right./ I hear there may be a few copies left. ?He may/might come today (tomorrow). 3. may表示祝愿,倒装。May +主语+动词原形。May you succeed!/May you all be happy. ☆may [might] as well…意为“不妨”、“还是…为好”等,用might 比用may 语气更委婉。如:I?m ready,so I might as well go now.我已准备好,因此不妨现在就走。 There?s nothi ng to do, so I may [might] as well go to bed. ☆may well... 完全可能 C. must, have to Must 1. 表示“必须”。否定式mustn?t表示“不可以”、“不准”、“禁止”等。 Everybody must obey the rules../You mustn?t lend it to others./You mustn?t speak like that to your mother. ☆在回答有“must” 的询问时,--- Must I go now? --- Yes, you must. ---No, you needn?t. / No, you don?t have to.

高中英语语法之情态动词 (一)情态动词的定义:情态动词表示说话人对某一动作或状态的态度。 (二)情态动词的特点:1)有一定词义;2)不受主语人称和数的变化影响;3)与主要动词 的原形(或称不带to的不定式)一起构成谓语(除ought to作固定词组看待)。 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。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。 He could be here soon. 他很快就来。We can't carry the heavy box. 我们搬不动那箱子。 I'm sorry I can't help you. 对不起,我帮不上你。 基本助动词与情态助动词最主要的区别之一是,基本助动词本身没有词义,而情态助动词则 有自己的词义,能表示说话人对有关动作或状态的看法,或表示主观设想: What have you been doing since? (构成完成进行体,本身无词义) I am afraid I must be going. (一定要) You may have read some account of the matter. (或许已经) 除此之外,情态助动词还有如下词法和句法特征: 1)除ought和used以外,其他情态动词后面只能接不带to的不定式。如果我们把ought to 和used to看做是固定词组的话,那么,所有情态动词无一例外地只能接不带to的不定式:We used to grow beautiful roses. I asked if he would come and repair my television set. 2)情态助动词在限定动词词组总是位居第一:They need not have been punished so severely. 3)情态助动词用于第三人称单数现在时的时候,没有词形变化,即其词尾无-s形式: She dare not say what she thinks. 4)情态动词没有非限定形式,即没有不定式和分词形式,也没有相应的动名词: Still, she needn't have run away. 5)情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合,情态助动词的现在 时和过去时形式都可以表示现在、过去或将来时间:Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6)情态助动词之间是相互排斥的,即在一个限定动词词组中只能出现一个情态助动词,但 有时却可以与have和be基本助动词连用:You should have washed the wound. Well, you shouldn't be reading a novel.
