宾语从句省略和 非谓语动词的区别
感官动词不能加do,要么用动词不定作感官动词的宾语补足语,这时动词不定式要省略to,
谓语和非谓语其实很好区别,用作谓语就是谓语动词,其他情况就是非谓语动词了.
宾语从句：在句子中起宾语作用的从句叫做宾语从句。
宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
宾语从句的连接词从属连词
连接宾语从句的从属连词主要有：that,if,whether. that引导表示陈述句的宾语从句，而if和whether引导表示“是否”的宾语从句。例如：
He told that he would go to the college the next year他告诉我他下一年上大学.I don’t know if there will be a bus any more.我不知道是否还会有公交车.Nobody knew whether he could pass the exam.没人知道他是否会通过考试.
连接代词连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等.连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.Do you know who has won Red Alert game?你知道谁赢了这一局红警游戏吗?I don’t know whom you should depend on.我不知道你该依靠谁.The book will show you what the best CEOs know.这本书会告诉你最好的执行总裁该了解些什么.Have you determined whichever you should buy,a Motorola or Nokia cell phone?你决定好是买诺基亚还是摩托罗拉的电话了吗?
连接副词连接副词主要有when,where,why,how,whenever,wherever,however等.He didn’t tell me when we should meet again.他没有告诉我什么时候我们能再见面.Could you please tell me how you read the new panel?你能展示给我怎么用这个新的操作盘吗?None of us knows where these new parts can be bought.没有人知道这些的新的零件能在哪里买到.
动词的宾语从句大多数动词都可以带宾语从句We all expect that they will win , for members of their team are stronger.我们都预料他们会赢,因为他们的队员更强壮.He told us that they would help us though the whole work.他告诉我们在整个工作中,他都会帮忙的.
部分“动词+副词”结构也可以带宾语从句I have found out that all the tickets for the concert have been sold out.我发现这场音乐会的所有票都买光了.Can you work out how much we will spend during the trip?你能计算出这次旅行我们将花费多少钱吗?
动词短语也可以带宾语从句常见的这些词有:make sure确保 make up one’s mind下决心 keep in mind牢记Make sure that there are no mistakes in your papers before you turn them in.在上交试卷前确保没有任何错误.
形容词的宾语从句常用来引导宾语从句的形容词有: sure,certain,glad,please,happy,sorry,afraid,satisfied,surprisedI am sure I will pass the exam.我确信我会通过考试.I am sorry that I have troubled you so long.很抱歉我这么长时间在打扰你.He is glad that Li Ming went to see him when he was ill.他很高兴在他生病的时候李明能去看望他.
if,wheter在宾语从句中的区别①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if②少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.③whether后可以加or not,但是if不可以.④在不定式前只能用whether.如： I can’t decide whether to stay. 我不能决定是否留下. ⑤避免歧异时,我们常用whether而不用if.6.哪些宾语从句不可以省略引导词that
当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;当宾语从句较长时;当主语状语置于主句尾,宾语从句之前时;当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;当宾语从句中的主语是this,that或this,that做主语的定语时;当宾语从句是双宾语中的直接宾语时;当宾语从句的主语是非谓语动词或主语从句时;当主语中的谓语动词是固定词组时;当宾语从句有it做其先行词时;在直接引语中,转述分句把宾语从句隔开时.
宾语从句的否定转移主句是谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.I don’t think he will come to my party.而不能说成I think he won’t come to my party.我认为他不会来我的舞会.I don’t believe that man is killed by Jim,is he?我认为那个人不是Jim所杀的,是不是?如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.We find that he never listens to the teacher carefully,does he?我们发现他从来不仔细听老师讲课,是不是?
但 they are the men that i saw yesterday 可以写成 they are the men i saw yesterday 就不是定语从句变成非谓语结构了。这个省略了关系代词 that/which 的句子仍然是定语从句。定语从句关系代词的省略也有一个先决条件：被修饰的先行词在从句里作宾语。如上面例句的 the men 就是从句的宾语：I saw the men yesterday。
