17、后。其他一些介词的宾语从句如果由连词 that 引导，则需用 it 先行一步，作形式宾语。如：He is a good student except that he is careless.他是一个好学生，只是有点粗心。You may rely on it that I shall help you.你可以指望我会帮助你的。介词宾语不可以用 which 来引导，而要用 what 来引导。如：Are you sorry for what youve done？你为你所做的一切感到内疚吗？3.某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure，glad，certain ，pleas

20、如果你想去的话，请告诉我一声”。5.宾语从句的否定转移。在 think，believe，suppose，expect 等动词后的宾语从句，有时谓语尽管是否定意思，却不用否定形式，而将 think 等动词变为否定形式。如：I dont think you are right.我认为你错了。I dont believe they have finished their work yet.我相信他们还未完成他们的工作。I dont suppose he cares，does he？ 我想他不在意，是吗？6.宾语从句的时态变化规律：（1）当主句是一般现在时态时，从句可根据需要用任何时态。（2）当主句是

22、e did you get the idea that I could not come？你在哪儿听说我不能来？Early in the day came the news that Germany had declared war on Russia.德国已对俄国宣战的消息一大早就传来了。注：同位语从句偶尔由从属连词 whether 引导。如：I have no idea whether hell come or not. 我不知道他是否来。连接代词 who，which，what 和连接副词 where，when，why，how 亦可引导同位语从句。The question that sho
23、uld do the work requires consideration.谁该干这项工作，这个问题需要考虑。We havent yet settled the question where we are going to spend our summer vacation.到哪儿去度暑假，这个问题我们还没有决定。It is a question how he did it.那是一个他如何做了此事的问题。解释：1.that 引导的同位语从句与定语从句之区别that 引导的同位语从句that 引导的定语从句5句法功能上that 只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。tha
24、t 替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。意义上从句是被修饰名词的内容。从句起限定作用，是定语如：The news that Mr.Li will be our new English teacher is true.（同位语从句，that 不可省。 ）李先生将是我们的新英语老师这个消息是真的。The news （that）he told me yesterday is true.（定语从句，that 在从句中作 told 的宾语，可省。 ）他昨天告诉我的消息是真的。2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气
25、should+动词原形表示。should 可省。如：This is our only request that this （should）be settled as soon as possible.这就是我们唯一的请求：尽快解决这个问题。5）定语从句定语从句及相关术语 1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有 that, which, who, whom, whose, as 等；关系副
26、词有 where, when, why 等。关系词常有 3 个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。注：关系代词有主语.宾语之分。一般 whom 作为宾语。4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用的表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。限定性定语从句一、关系代词（在句中作主语、宾语或定语）1. that 既可代表事物也可代表人，
27、which 代表事物；它们在从句中作主语或宾语，that 在从句中作宾语时常可省略关系词，which 在从句中作宾语也可以省略。eg ：this is the book （which）you want。而且，如果 which 在从句中作“不及物动词介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词 which 的前边，但有的则放在它原来的位置 2. which 作宾语时，根据先行词与定语从句之间的语义关系，先行词与 which 之间的介词不能丢3. 代表物时多用 which，但在带有下列词的句子中用 that 而不用 which，这些词包括当先行词是anything, everyt
28、hing, nothing , none 等不定代词时，或者是由 every, any, all, some, no, little, few, much 等修饰时等，这时的 that 常被省略 还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有 which 时,都只能用 that4. who 和 whom 引导的从句用来修饰人，分别作从句中的主语和宾语，whom 作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. whose 是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导
29、的从句修饰物体时, 可以与 of which 调换 ,表达的意思一样。二、关系副词（在句中作状语）关系副词=介词+ 关系代词Why=for which6Where=in/ at/ on/ . which (介词同先行词搭配)When=during/ on/ in/ . which ( 介词同先行词搭配)1. where 是关系副词，用来表示地点的定语从句。2. when 引导定语从句表示时间注值得一提的是，表示时间“time“一词的定语从句只用 when 引导，有时不用任何关系代词，当然也不用 that 引导。 By the time you arrive in London, we will
30、 have stayed there for two weeks. I still remember the first time I met her. Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。3. 当从句的逻辑主语是 some, any, no, somebody, anybody, nobody, something, anything, everything 或nothing 时，常用 there is 来
31、引导There is somebody here who wants to speak to you. 这里有人要和你说话。非限定性定语从句非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立 1. which 引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：Charles Smith, who was my former teacher, retired last year. 查理史密斯去年退休了，他曾经是我的老师。My h
32、ouse, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。Liquid wate
33、r changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。4. 有时 as 也可用作关系代词5. 在非限定性定语从句中，不能用关系副词 why 和关系代词 that，而用 who, whom 代表人，用 which, whose 代表事物.；关系代词引导的定语从句1.who 指人在从句中做主语(1) The boys who are playing football are from Class One.(2) Yesterday I helped an old man who lost his way.2. whom 指人

47、bition was held. 在句 1 中，is 后应跟表语，只有 the one 可以，而后面的 you visited a few days ago 则做 one 的定语从句。而句 2 中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词 where，又因 in the museum 词组，可用介词 in + which 引导地点状语。而此题中，介词 on 用的不对，所以选 A。 关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( wher
