大家好,我是正在努力学英语的阿镜。
今天整理英语中情态助动词shall/should/dare的用法。
4、shall
● The room is so dirty. Shall we clean it? 房间很脏。我们清扫一下吧?
● Shall he come tomorrow? 你要他明天来吗?
(2)shall用于第二、三人称的肯定句,表示命令、警告、威胁、强制、允诺等。
坚持不懈的奋斗英语,● You shall do it whether you want to or not.不管你愿意不愿意,你必须做这项工作。(命令)
● Tell him that he shall have the book as soon as I finish it. 告诉他这本书我一看完就给他。(允诺)
● You shall pay for it. 你一定会受到惩罚的。(威胁)
5.should
(1)should表示建议(Suggestion)时,可译为“应该”。
● We should learn about the computer and make full use of it. 我们应该了解计算机并加以充分利用。
(2)should表推测(Deduction)、可能(Possibility)时,往往有一定的根据,含有“按道理应该”之意。
坚持不懈的英文是:persistence persistence 读法 英 [pəˈsɪstəns] 美 [pərˈsɪstəns]短语:persistence of vision 视觉暂留;视觉残留;持续视觉 示例:Skill come。
● They should be at home by now for they have been away for two hours. 他们现在应该在家了,因为已经离开两个小时了。(根据他们已经离开两小时做出推测)
(3)should有时表示说话人的感情,如惊奇、愤怒、失望等。如:
● Why should I go? 我干嘛要去?(表不满)
● I was shocked that she should have said such a thing to you. 她竞然对你说这种话,真让我吃惊。(表惊奇,且说话的动作发生在过去,用should have said)
● I am surprised that you should think this city is a dull place to live in. 你竞会认为住在这个城市里没有什么意思,我很吃惊。(表惊奇)
Keep on working hard and be persistent. be persistent可以用stick to it代替
● I am sorry that she should be so stubborn. 我很遗憾,她竞这样固执。(表失望)
注意:ought to更正式,表示建议、推测时,译为“应当”、“应当会”,与should通用;但表示道义上的责任或义务时只能用ought to。
● We ought to/should learn about the computer and make full use of it. 我们应该了解计算机并加以充分利用。(否定时用ought not to=shouldn't)
● Since he works hard,he ought to/should succeed. 由于他很努力,应该会成功。
● He ought to/should have arrived in New York by now. 他现在应该已经到达纽约了。(“ought to/should have +过去分词”表示“推论到目前为止已经完成的动作”,意思是“应当已经”,常与by now“到目前为止”连用)
● You are his father. You ought to take care of him. 你是他父亲,你应当照顾他。(道义上的义务用ought to)
6. dare
(1)dare用作情态动词,后跟动词原形,主要用于疑问句、否定句和条件句中。如:
● Dare you catch the mouse? 你敢抓那只老鼠吗?(疑问句)
● How dare you speak to me like that? 你竟然敢这样对我说话?(How dare引导的疑问句)
persevere 含褒义,强调坚持不懈的努力。insist 通常用于对意见、主张等的坚持。persist 用于褒义指坚持继续做某事,但更常用于贬义,指不听劝告,顽固坚持。cling 和to连用,指对信仰、意见、习惯等的坚持。adhere 与to连用,。
● My sister dare not go out in such a dark night. 我妹妹不敢在这么黑的夜晚出门。(否定句)
● I wonder whether he dare do it. (条件句)我怀疑他敢不敢做这事。
● (2)肯定句中dare用作实义动词,有人称和数以及时态的变化。其后的动词不定式可带to也可不带,一般肯定句中要有to,否定句和疑问句中没有to。如:
● He dares/ dared to jump down from the top of the wall. 他敢从墙头跳下来。(肯定句中dare用作实义动词,有人称和数以及时态的变化,且dare后一般有to)
● She dared me to jump the stream. (dare sb to=challenge sb to,dare做及物动词,有“向某人挑战”的意思) 她向我挑战跳过这条小溪。
never give up 永不放弃
● I daresay (that) he will be late again,我敢说他又会迟到。(句型I daresay (that)...中daresay是一个词,相当于 dare say)
