dare&need的用法

Dare的用法: 1.Depending on its sense,the verbdare sometimes behaves like an auxiliary verb (such as can or may ) and sometimes like a main verb (such aswant or try ). When used as an auxiliary verb,dare does not agree with its subject: 从意义上来说,动词dare 有时相当于助动词(如can能或may可能),有时相当于实义动词(如want想或try试着)。当用作助动词时,dare 不和主语一致: Let him say that if he dare. 如果他敢的话让他说, 2.It also does not combine withdo in questions, negations, or certain other constructions: 它也在疑问句、否定句和其他某些结构中,不需和do 连用: Dare we tell her the truth? 我们敢告诉她实情吗? I dare not mention their names. 我不敢提他们的名字。 3.Finally, it does not taketo before the complement verb that follows it: 最后,在紧跟其后的辅助动词前不用带上to : If you dare breathe a word word文档格式规范word作业纸小票打印word模板word简历模板免费word简历 about it I'll never speak to you again. 如果你敢说出去一个字,就再不和你说话。 4.When used as a main verb,dare does agree with its subject ( 当用作实义动词时,dare 一定要和主语一致( If he dares to show up at her house I'll be surprised), 如果他敢出现在她的房子里,我会感到吃惊), 5.and it does combine withdo ( 它必须和do 连用( Did anyone dare to admit it?). 有人敢于承认吗?)。 6.It may optionally taketo before the verb following it: 有可能选择性地在紧跟其后的动词前加to : No one dares (or dares to ) speak freely about the political situation. 没有人敢(或dares to ) 自由地谈论政治形式。 7.The auxiliary forms are used primarily in present tense questions, negations, imperatives, and conditional clauses.These forms differ subtly in meaning from the main verb formsin that they emphasize the attitude or involvement of the speakerwhile the main verb forms present a more objective situation.ThusHow dare she take the exam without ever once coming to class? expresses indignation at the student's action, whereasHow did she dare to take the exam without ever once coming to class? is a genuine request for information. Whendare is used as a transitive verb meaning “challenge,” only main verb forms are possible andto is required: 助动词形式主要用于一般现在时疑问句、否定句、祈使句和条件从句中。这些形式和实义动词形式的意思有细微的差别,即他们强调说话者的态度和参与,而实义动词形式给出一个较客观的形势。因此她怎么敢从未上过课就参加考试呢? 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 示对该学生行为的愤怒,然而她从未上过课怎么敢参加考试呢? 是一真实的信息需求,当dare 用作及物动词意指“挑战”时,只能是实义动词形式而且要接to : Anyone who dares (not dare ) him to attempt (not just attempt ) it will be sorry. 任何敢于(不是dare ) (不仅仅是attempt ) 挑衅他去做的人会遗憾的。 Need的用法: 1.Depending on the sense,the verbneed behaves sometimes like an auxiliary verb (such as can or may ) and sometimes like a main verb (such aswant or try ). When used as a main verb,need agrees with its subject, takesto before the verb following it, and combines withdo in questions, negations, and certain other constructions: 根据语义,动词need 有时当作助动词来使用(如can 或may ),有时象实义动词(如want 或try )。当用作实义动词时,need 和主语一致,把to 放在其后面动词的前面,在疑问句、否定句或某些特定的造句法上和do 连用: He needs to go. 他想走。 Does he need to go so soon? 他这么快就要走吗? He doesn't need to go. 他不需要走。 2.When used as an auxiliary verb,need does not agree with its subject, does not taketo before the verb following it, and does not combine withdo : 当用作助动词时,need 不用和主语一致,不用把to 放在其后动词的前面,并且不用和do 连用: He needn't go. 他不必走。 Need he go so soon? 他这么快就要走吗? 3.The auxiliary forms ofneed are used primarily in present-tense questions, negations, and conditional clauses. They differ subtly in meaning from the main verb forms in that they always refer to an externally imposed obligation.Hence one might sayYou needn't (or less formally, don't need to ) fill out both forms, but where the sense of necessity is internal to the subject,only the main verb can be used: Need 的助动词形式主要用于现在时态的疑问句、否定句和条件句中。它们在意思上和用作实义动词的形式有细微的区别,它们总指外部加强的压力。因此我们可以说你没必要(或不太正规的don't need to ) 填两份表格,但是对于物体来说需要的意思是内在的,所以只能用实义动词: I don't need to (not needn't ) be told how to manage my own affairs. 我不需要(而不是needn't ) 被告诉怎知管理自己的事情。 4.Note also that the use ofneed as an auxiliary is often accompanied by a presupposition that the activity in question has in fact been performed.The boys needn't have spoken frankly implies that they did in fact speak frankly, whereas the sentenceThe boys did not need to speak frankly does not; only the latter could be followed by a clauselikethey conveyed their meanings by indirection. 还需注意need 用作助动词时经常伴随一个先决条件,质问的动作事实上已经完成了。那些男孩们本来不需要坦诚相告的意味着他们事实上已经坦率地说了,然而这个句子男孩们不需要坦诚地说话就没有这个意思;只有后者可以在其后跟这样一个句子,如他们间接地表达他们的意思
