not until用法

until可用作介词或连词,意为“到……时候为止”、“到……时候才”或“在……时候以前不”。什么情况下表达什么意思,关键要看(主)句中的谓语动词是终止性动词还是延续性动词。1.如果(主)句中的谓语动词是终止性动词,应采用“...not...until...”结构,意为“……到……时候才……”。例如:Youmustn"teatanythinguntilyouseethedoctor.看过医生之后,你才能吃东西。Don"tgetoffthebusuntilithasstopped.车停稳了以后再下车。2.如果(主)句中的谓语动词是延续性动词,那么谓语动词用肯定式或否定式,它们所表达的意思有所不同。1)如果谓语动词为肯定式,则until译为“到……时候为止”。例如:IwatchedTVuntilshecameback.我看电视一直看到她回来。2)如果谓语动词为否定式,则until应译为“到……时候才”,即“在……以前不”。例如:IdidnotwatchTVuntilshecameback.(=IbegantowatchTVwhen/aftershecameback.)直到她回来我才开始看电视。3.用终止性动词作谓语时,until既可以和not连用,又可以和never,nobody,nothing,few,little,seldom,hardly等含否定意义的词连用。例如:Ihadnotseenhimuntil1990.(=Ihadneverseenhimuntil1990.)1990年以前我从未见过他。Don"tputoffuntiltomorrowwhatyoucandotoday.(=Neverputoffwhatyoucandotodaytilltomorrow.)今日事,今日毕。4.连词until引导的从句中谓语动词的时态。1)主句的谓语动词为一般现在时或一般将来时时,until从句中的谓语动词为现在完成时,用来强调从句谓语动词表示的动作发生在主句谓语动词表示的动作之前。试比较:Iwon"tgotobeduntilIhavefinishedmyhomework.我要完成作业才睡觉。2)主句中的谓语动词为一般过去时时,从句中的谓语动词为过去完成时,用来强调从句谓语动词的动作发生在主句谓语动词表示的动作之前。试比较:LiLeididn"tcomeuntilthefilmhadbegun.直到电影开演,李雷才来。〔特别提醒〕till和until的意思基本相同,用法也基本一样,但until语气较重,多用于较正式的文体里。till多用于英式英语,until多用于美式英语;till不能用在句首,也不能用在not开头的短语或从句里,而until可以。例如:Untilhecamehome,weknewthenews.在他到家之前,我们不知道这消息。Notuntilnineo"clockyesterdayeveningdidwefinishthework.直到昨晚九点,我们才完成这项工作。

notuntil用法

not until的用法时态如下:notuntil的主句用一般将来/过去将来,从句用一般过去时/一般现在时。unti引导的时间状语是一个点时间,不是一个段时间,所以not until表示过去的事情时,通常不用完成时态。英语语法中的时态(tense)是一种动词形式,不同的时态用以表示不同的时间与方式。时态是表示行为、动作、状态在各种时间条件下的动词形式,在英语中有16种时态。一般过去时:例:I didnt leave the house until he came back.释义:直到他回来我才离开家。一般现在时:例:Dont leave until I come back.释义:在我回来之前不要离开。一般将来时:例:I wont leave until you do.释义:你不走我就不走。

not……until……的解释与用法?

not .until翻译成“直到.才.”,not前面的动词是瞬间性动词 until单独出现的时候前面要加 延续性动词,翻译成,“在.之前一直做.” 就记住翻译的意思就好~~~~~~~~否则容易混淆呢 不过值得注意的是这个哦 No until放在句首的时候要倒装,并且,是『前不倒后倒』 前不倒后倒啥意思? 这个意思:Not until I got home, did I found. 这个要区别于:『前倒后不倒』的几个特殊例子: not only but also no sooner than,hardly when.就这三个特殊 还有一点:像你这个要翻译的句子一样:not until用于强调句的时候不倒装~~~~~~~~~~~~~~~~~~~不倒装哦!

until和notuntil的区别

1、意义上有所区别not until意思是直到什么时候才会去做某事,否则不去做。until一直到某个时候一直做某事。2、所属句中的动词属性有区加根据1不难理解,not until 所修饰的动词不见得是连续性的,而until 修饰的动则须是连续性的。3、句法功能上有区别until一般不放在句首,后面跟时间词或表示时间条件的状语或从句连用 。not until:可放句首,但主句要用倒装。扩展资料:I studied Englis until 9 o"clock last night. 我咋晚学英语一直学到9点钟.(表示9点前一直在学)I did not study Englis until 9 o"clock last night. 我咋晚直到9点钟才学英语.(表示9点才开始学)参考资料:百度百科_until(英语单词)

如何区别not.until与not.unless的用法

until 的意思是 up to the time when(直到……时为止),表示时间。如:(1) The hot weather lasted until September. 炎热的天气一直持续到9月。(2) I waited until three o"clock, but he didn"t come. 我一直等到3点,但他没来。(3) The air becomes thinner and thinner until it disappears. 空气越来越稀薄,直到消失。not…until…的意思是:直到……才……;在……之前不要……。如:(1) They didn"t find her until the next day. 他们直到第二天才找到她。(2) She won"t go home until after the exam. 她要考完试之后再回家。(3) I didn"t believe it till I saw it with my own eyes. 我原先不相信,直到亲眼看了才相信。(4) I didn"t miss the key until I got home and found it wasn"t in my bag. 直到我回家发现钥匙不在口袋里才知道丢了。unless 的意思是 if…not(如果不……),表示条件。如:(1) You will fail unless you work hard. 你若不努力就会失败。(2) Come tomorrow unless I phone. 如果我不打电话,你明天就来吧。(3) I"ll take the job unless the pay is too low. 如果工资不是太低,我会接受这一工作的。not…unless…的意思是:除非……否则不……。如:(1) Don"t act unless you"re certain. 没有把握就不要做。(2) I won"t go unless I"m invited. 除非请我,不然我就不去。(3) She will not work hard unless you push her. 除非有人督促她,不然她不会努力。(4) The targets would not be achieved unless other departments showed equal commitment. 除非其他部门同样努力,否则这些目标无法达成。(5) He won"t want to eat it unless he"s really hungry, in which case he"ll eat almost anything. 除非很饿,否则他不会吃东西,一旦饿了,他几乎什么都吃。但在有些情况下,用 not…until…和 not…unless…都可以,只是说话者的侧重点稍有不同。如:(1) Don"t start work again until you"re completely better. 在病没完全好之前,请不要开始干活。(侧重时间:开始干活的时间是病好之后)(2) Don"t start work again unless you"re completely better. 除非病完全好了,否则就不要开始干活。(侧重条件:开始干活的条件是病好)典型考题:下面两道题答案都只能选 until:(1) I didn"t manage to do it ______ you had explained how.(1987年高考题)A. unless  B. until  C. when D. since(2) —Was his father very strict with him when he was at school?—Yes. He had never praised him _______ he became one of the top students in his grade. (2003北京春季高考题)A. after B. unless C. until D. when这两题要选 unless除了与句意有关外,还与句子时态有关。在这两个句子中,如果要填 until,就说明说话者强调条件,如果是这样的话(联想大家都熟悉的“主将从现”),主句的时态就可能考虑要用将来时态(比如过去将来时、过去将来完成时等)。比如:(1) I wouldn"t have managed to do it unless you had explained how.(此句只是为了顺应语意而写,其实这句是不对的,因为这样一来,句子就成了虚拟语气,而 unless 通常不用于虚拟语气,正确的写法是:I wouldn"t have managed to do it if you hadn"t explained how.)(2) He would never praise him unless he became one of the top students in his grade.(这句的主句谓语用 would never praise,后面用 unless 来强调条件就对了)

如何区别not.until与not.unless的用法

until 的意思是 up to the time when(直到……时为止),表示时间。如: (1) The hot weather lasted until September. 炎热的天气一直持续到9月。 (2) I waited until three o"clock, but he didn"t come. 我一直等到3点,但他没来。 (3) The air becomes thinner and thinner until it disappears. 空气越来越稀薄,直到消失。 not…until…的意思是:直到……才……;在……之前不要……。如: (1) They didn"t find her until the next day. 他们直到第二天才找到她。 (2) She won"t go home until after the exam. 她要考完试之后再回家。 (3) I didn"t believe it till I saw it with my own eyes. 我原先不相信,直到亲眼看了才相信。 (4) I didn"t miss the key until I got home and found it wasn"t in my bag. 直到我回家发现钥匙不在口袋里才知道丢了。 unless 的意思是 if…not(如果不……),表示条件。如: (1) You will fail unless you work hard. 你若不努力就会失败。 (2) Come tomorrow unless I phone. 如果我不打电话,你明天就来吧。 (3) I"ll take the job unless the pay is too low. 如果工资不是太低,我会接受这一工作的。 not…unless…的意思是:除非……否则不……。如: (1) Don"t act unless you"re certain. 没有把握就不要做。 (2) I won"t go unless I"m invited. 除非请我,不然我就不去。 (3) She will not work hard unless you push her. 除非有人督促她,不然她不会努力。 (4) The targets would not be achieved unless other departments showed equal commitment. 除非其他部门同样努力,否则这些目标无法达成。 (5) He won"t want to eat it unless he"s really hungry, in which case he"ll eat almost anything. 除非很饿,否则他不会吃东西,一旦饿了,他几乎什么都吃。 但在有些情况下,用 not…until…和 not…unless…都可以,只是说话者的侧重点稍有不同。如: (1) Don"t start work again until you"re completely better. 在病没完全好之前,请不要开始干活。(侧重时间:开始干活的时间是病好之后) (2) Don"t start work again unless you"re completely better. 除非病完全好了,否则就不要开始干活。(侧重条件:开始干活的条件是病好) 典型考题: 下面两道题答案都只能选 until: (1) I didn"t manage to do it ______ you had explained how.(1987年高考题) A. unless  B. until  C. when D. since (2) —Was his father very strict with him when he was at school? —Yes. He had never praised him _______ he became one of the top students in his grade. (2003北京春季高考题) A. after B. unless C. until D. when 这两题要选 unless 除了与句意有关外,还与句子时态有关。在这两个句子中,如果要填 until,就说明说话者强调条件,如果是这样的话(联想大家都熟悉的“主将从现”),主句的时态就可能考虑要用将来时态(比如过去将来时、过去将来完成时等)。比如: (1) I wouldn"t have managed to do it unless you had explained how.(此句只是为了顺应语意而写,其实这句是不对的,因为这样一来,句子就成了虚拟语气,而 unless 通常不用于虚拟语气,正确的写法是:I wouldn"t have managed to do it if you hadn"t explained how.) (2) He would never praise him unless he became one of the top students in his grade.(这句的主句谓语用 would never praise,后面用 unless 来强调条件就对了)
2023-07-23 15:04:111

not till 和 not until意思相同吗?

till和until都可以用作连词和介词,用于肯定句和否定句。用于肯定句时,只与持续性动词连用,有一个not...until的形式是固定的表示"到...为止"。用于否定句时,通常与瞬间动词连用,也可与持续性动词连用,表示"直到...才"的意思。这两个词一般情况下可以相互换用。例如: We waited for him until/till six o"clock. 我们等他到一直等到六点钟。 The pupils will not begin the meeting till/until their class supervisor comes. 学生们等到班主任一到就开始开会。 They didn"t talk until/till the interpreter came. 直到译员到,他们才交谈。 He did not go to bed until/till he had made sure that nothing was wrong with the pipes. 他检查水管,确准它们没有毛病,才去睡觉。 当until用于句首时,一般不能用till代替。在以not开始的从句或短语里,till一般也不可代替until,而且这种句式要用倒装语序。例如: Until the last minute of the match we kept playing. 直到比赛的最后一分钟,我们仍然坚持奋战。 Not until he had finished his work did he go home. 他直到把工作做完,才回家去。
