英语 问题 3 个

    until：直到。。。为止一般和till可以互换，中文虽然都是“直到”的意思，但还是在意思上有一点区别的。till表示肯定，而until表示否定(有一点抽象，不理解可以不管)接下来两句话是一个意思I will be here till he comes back。
    I won't leave here until he comes back。可以看出一点差别了吧，until一般和not连用，以not……until为句式。而till一般单独使用。
  两句的翻译是:我将一直在这里直到他回来。我将不会离开这里直到他回来。not untill：直到。  。。才。

    （1）。until是till的强调形式，但是它们表达的意义是相同的，都表示"直到某时"。不过，当主句是否定句时，它引出的意思是"直到（某时）（某动作）才（发生）" ，这时候常会出现"not until …"的结构，如果将 "not until …"的结构放在句首，那么主句要写成倒装句。
    till until 可以通用，和持续性动词连用 e。g。I will wait here until/till you come。（wait就是一个持续性动词）。not until和瞬间性动词连用 e。
  g。I will not leave until you come。  （leave离开，是瞬间就能完成的动作，是瞬间性动词，故用not until)（2。）too 形容词或副词原形 to do sth ，意思是”太……而不能……“如：1)。
  He is too young to go to school 。2)。 He ran too slowly to catch the early bus 。      他跑得太慢不能赶上早班车。
  （3）。that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：　第一、that 用作形容词（后接复数名词时用those）。
    　它用来指已被提到的人或物；也可表对比，指两个中较远的那个。　What about that book you borrowed from me last month？　请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
  　that little son of his 他那个小宝贝儿子　That George！乔治那家伙！（含有轻蔑语气）　第二、that 用作代词。  　1。 that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
  　That is what he told me。　What is that (which) you have got in your hand?　The price of rice is higher than that of flour。
    　2。 that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）　He talked about the teachers and schools that he had visited。
    　I think it one of the most wonderful films that the film company has ever produced。
  　She has little information that is useful for our research。   　Is there anything that I can do for you?　请注意，that 在定语从句中作宾语时通常可省略。
  　The books (that) I sent you will help you in your studies。　第三、that 用作连词，引导名词性从句,状语从句和强调句。  　1。
   that名词性从句。　①引导宾语从句。及物动词后的引导词that可省略。　I didn't expect (that) he could win the championship。　The teacher pointed out that Tom was not working hard enough。
    　② 引导主语从句。通常采用it作形式主语的句型。　That the earth goes around the sun is known to everyone。　（It is known to everyone that the earth goes around the sun。
    ）　③引导表语从句。　The trouble is that we are short of money。　④引导同位语从句。　引导同位语从句的that和引导定语从句的that是不同的。
  前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。  举例说明：　The news that he resigned from office surprised us。
  　The idea that he holds is very common nowadays on campus。 　2。 that引导状语从句　①引导目的状语从句。  　Bring it nearer that I may see it better。
  　②引导结果状语从句。　What have I done that he should be so angry with me?　③引导原因状语从句。　I am afraid that I will fail in the driving test。
    　④引导让步状语从句。意为“虽然、尽管”。　Difficult that/as the task was, they managed to accomplish it on time。
  　⑤引导条件状语从句。意为“假使、假设”。　Supposing that you were in my position, what would you do?　On condition that you were lost in the desert, you should ask for help as soon as possible。
    　3。 引导强调句。　It is Mrs。 White that makes the decision in her family, not her meek little husband。
  　It is an ill wind that blows nobody good。  　第四、that用作副词。　1。 that用作普通副词。　I was that/so angry I could have hit him。
  　2。 that用作关系副词。引导定语从句，可以代替when，where， why或 in which，常可省略。　I will never forget the evening (that) / when we went to the theatre。
    　The house (that)/where I used to live has been knocked down。　第五，与that 有关的常见重要短语。　1。
   in that，意为“既然、因为”。　Criticism and self-criticism is necessary in that it helps us correct our mistakes。
    　2。 now that，意为“既然、由于”。　Now that they have taken matters into their hands, the pace of events has quickened。
  　3。 see (to it) that，意为“注意、务必做到、保证”。  　We will see to it that she gets home early。　See to it that you are not late again。
  　4。 seeing that，意为“鉴于、由于”。　Seeing that it is 8 o'clock, we'll wait no longer。  　Seeing that he was busy with his work, I didn't disturb him。
  　以上是that主要用法的概述，希望能对你有所帮助。当然，that还有其他的一些用法，需要我们在学习的过程中不断地积累和总结。
