1)不用that的情况 a) 在引导非限定性定语从句时。 (错) The tree, that is four hundred years old, is very famous here. b) 介词后不能用。 We depend on the land from which we get our food. We depend on the land that/which we get our food from. 2) 只能用that作为定语从句的关系代
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一、引导名词性从句的连接词 引导名词性从句的连接词可分为三类:连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示
同位语从句和定语从句在形式上基本相同,都是跟在名词或代词之后,且又常由that引导。但它们的句法功能却是不同的,我们可以从三个方面来加以区别。 (1)根据that来区别。引导定语从句的that是关系代词,除了起连接主句和从句的作用外,还代替先行词在从句中充当一个成分。而且这个that还常可以用which来代替。引导同位语从句的that是个连词,只起连接主句和从句的作用,在从句中不充当任何成分,也不能用which来代替。例如: The fact that(which)
as 用于引起定语从句,多和such连用。 Such people as you decribe are rare nowadays. 你描绘的那种人如今很少见了。 Lets discuss only such question as concern everyone of us. 我们只谈与我们每人都有关的问题吧。 也可用在下面这类句子中: He oppose the idea, as could be expected. 正如可以预料到的,他反对这个意见
1)what = the thing which;whatever = anything What you want has been sent here. Whatever you want makes no difference to me. 2) who= the person that whoever= anyone who (错)Who breaks the law will be punished. (错)Whoever robbed the ba
1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替) 2)The parents will use what they have to send their son to technical school. (what 可以用all that代替)
限制性定语从句和非限制性定语从句有四大区别,现作简要介绍。 一、在句中作用不同 限制性定语从句对被修饰的先行词有限定制约作用,使该词的含义更具体,更明确。限制性定语从句不能被省略,否则句意就不完整。 非限制性定语从句与先行词关系不十分密切,只是对其作一些附加说明,不起限定制约作用。如果将非限制性定语从句省去,主句的意义仍然完整。 二、外在表现形式不同 限制性定语从句因与先行词关系密切,所以不可以用逗号将其与主句隔开;而非限制性定语从句与先行词关系不十分密切,所以
引导宾语从句常用虚拟语气的动词有哪些呢?大家请看下面的表格,非常主要,各位同学需要熟记。建议v.suggest advise recommend(推荐) move(提议) motion(打手势) propose (建议)主张v.insist hold(持有…意见) urge(催促、力劝) maintain(坚持…意见) advocate (提倡)要求v.ask request require demand desir
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。 As we know, smoking is harmful to ones health. The sun heats the earth, which is very important to us. 典型例题 1)Alice received an invitation from her boss, __
很多同学可能都会觉得在使用定语从句的时候,有时不知该选择that还是which作为引导词。其实只要记得以下几点,并多做练习,在具体的句子中加以理解,一切问题就可以迎刃而解了。 首先,that和which在从句里都可以做宾语和主语,做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that,which,还是whom。但是which能引导非限制性定语从句,that则不行。 其次,记得以下只能用that的几种情况:
当宾语从句后跟有宾语补足语时,通常在宾语从句处使用形式宾语it,而将真正的宾语从句移至句末: I think it best that you should stay here. 我认为你最好住这儿。 He hasn’t made it known when he is going to get married. 他还没宣布他何时结婚。 She found it difficult to answer the question. 她发现回答这个问题很困难
1)介词后面的关系词不能省略。 2)that前不能有介词。 3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。 This is the house in which I lived two years ago. This is the house where I lived two years ago. Do you remember the day on which you joined our clu
第一、 在限制性定语从句中的区别: as 的用法:其通常和such\ the same连用,代指物在从句中做主语或宾语 This is the same pen as I bought yesterday。 这种笔和我昨天买的笔一样(同样的但不是同一个)。引导定语从句的关系词在从句中做宾语,因先行词被the same所修饰所以用as引导 注意:上句与下句的区别 This is the same pen that I used yesterday.这就是昨天我使用的
whether与that均可引导名词从句,该如何区别呢? __________ we’ll go camping tomorrow depends on the weather. A. If B. Whether C. That D. When 此题应选 B。容易误选A,C。 1. 关于if与whether:两者都可引导宾语从句,常可换用; 但若引导主语从句,则用whether (不用if),排除A。又如。如: 他是否会来还是个问题。 误:If h
方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如: This is the mountain village where I stayed last year. Ill never forget the days when I worked together with you. 判断改错(注:先显示题,再显示答案,横线;用不同的颜色表示出。) (错) This is the
从句谓语通常用过去式表示现在或将来,有时也用过去进行时或“should+动词原形”(较少见,且should不能省略),其意为“(早)该干某事了”。如: I think its time you went to bed. 我想你该睡觉了。 Its time we went [were going, should go]. 我们该走了。 I think its time they were taught a lesson.
同学们常会遇到把含有宾语从句的复合句转化为简单句,使其与原句意思相同(或相近)的试题。下面就介绍几种常用的简化宾语从句的方法: 方法一:当主句谓语动词是hope, decide, wish, choose, agree, promise等,且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。例如: Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。 1)when, where, why 关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如: There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。 Beijing is the place where (in which) I was born
在复合句中 , 修饰名词或代词的从句叫定语从句 , 被修饰的名词或代词叫先行词 , 引导定语从句的有关系代词 who, whom, whose, which, that等和关系副词where, when, why等 , 关系代词和关系副词在定语从句中担任句子成份。 1.由who引导的定语从句中 , who用作主语 , 如 : This is the boy who often helps me. 2.由whom引导的定语从句中,whom用作宾语,如:The man w
关系代词which引导的定语从句, 指物,在从句中可以作主语、宾语等。多数情况下,可与that互换。但是要注意当从句中,介词提前只能用which,而且,在非限制性定语从句中,which引导的句子单独翻译为一句话。 (1)“The ability to guard customer data is the key to market value, which the board is responsible for on behalf of sharehold
