列举常用引导词归纳小升初知识点
在我们的学习时代,不管我们学什么,都需要掌握一些知识点,知识点就是“让别人看完能理解”或者“通过练习我能掌握”的内容。相信很多人都在为知识点发愁,下面是小编精心整理的列举常用引导词归纳小升初知识点,欢迎大家分享。
引导状语从句的词语叫从属连词。不同作用的状语从句通常由不同的从属连词来引导。如:
1. 引导时间状语从句的从属连词主要有when, while, as, whenever, before, after, since, until, till, as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once等。
2. 引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case 等。
3. 引导目的状语从句的从属连词主要有 in order that, so that, in case, for fear等。
4. 引导结果状语从句的从属连词主要有so that, so…that, such…that等。
5. 引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that), considering (that) 等。
6. 引导让步状语从句的从属连词主要有although, though, even though, even if, while, however, whatever, whoever, whenever, wherever等。
7. 引导方式状语从句的从属连词主要有as, like, as if, as though, the way等。
8. 引导地点状语从句的从属连词主要有where, wherever, everywhere等。
9. 引导比较状语从句的从属连词主要有than和as…as。
定语从句引导词that
1. think it + adj + that
在讲今天的语法之前,我们回顾一下平时同学们在写作以及阅读中可能比较疑惑的例句:
I think it important that you tell your mother the truth.
疑惑之处在于,it后面为什么没有is?
例句采用了这样的句型:“think it + adj”。此处,it为形式宾语,that引导的宾语从句才是真实宾语,而important是宾语补足语。所以,it是形式宾语而不是主语,不需要加be动词。
一般情况下,各位更熟悉的句型是:“I think (that) it is important that... ”;这两者都是正确的,注意区分和辨别。
感兴趣的同学还可以去这个网站看看:English Language & Usage。它给出了以下几个类似的例句:
e.g. We do not think it necessary to go.
e.g. Some people do not think it important to be thrifty.
2. 定语从句中的that
定语从句中比较容易处理方面是,定语从句中“that”多可省略,表现为关系代词作宾语的情况:
e.g. He must be the man (that) you have been looking for.
此处,man作looking for的宾语。
至于不可省略的that,这里小编只举两例,算是比较常用的规则哦:
(1)紧接着上面阐述,除了关系代词作宾语的情况外,其余时候多不能省略that。比如小编给各位找来一个作主语的例子,各位可以举一反三:
e.g. All that glitters is not gold.(发光的未必都是金子。)
此处,that指代主语,不可以省略。
(2)我们都知道that引导定语从句,可指人也可指物,算是兼有“who”和“which”的作用;但当定语从句修饰的先行词既有人又有物时,那么就只能用that且不可省略了。
e.g. I still remember the things and persons that I met when I traveled to Tibet.
接下来再给各位同学出一道题检验一下今天学习的知识点到底掌握了没有,题目如下:
This is the fastest train that there is to Beijing.
上句话中的that是否可以省略?
A. yes
B. no
答案:A。可以省略。
(1)首先我们来判断一下此处that引导的从句在句子中是什么成分:
This is the fastest train that there is to Beijing .
由于there be句型的特殊性,并不是跟在be动词后面的就一定是宾语,there be句型本身就是一个倒装。这种句型之所以要用there作引导词,而把主语置于动词之后,是为了使主语成为信息中心,以达到引出新话题的目的。上述例句中的train是定语从句中的主语成分。
(2)认真学习的同学肯定还记得上期小编总结了一句“定语从句中that多可省略,表现为关系代词作宾语的情况”,因此各位就倾向于记住宾语之外的成分都不可以省略that,但there be结构却是特例。具体语法点为:在there be结构中出现定语从句,或在定语从句中出现there be时,用作主语的关系代词也可省略。
(3)因此,上述例句中的train虽作从句的主语成分,但由于there be结构的特殊性,that仍旧可以省略。此处特例建立在固定结构的用法基础上,也算是有规律可循的特例了。
只能用that的几种情况:
1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。
如:We should do all that is useful to the people. 我们应该做一切有益于人民的事情。
Please tell me anything that you know about the matter. 有关此事,凡是你所知道的请告诉我。
2. 当先行词被any, few, little, no, all, much, some等词修饰时。
如:You can take any seat that is free. 任何空着的座位你都可以坐。
There is little work that is fit for you. 几乎没有适合你的工作。
3. 当先行词为序数词或被序数词所修饰时。
如:When people talk about the cities of China, the first that comes to my mind is Beijing. 人们谈论起中国的城市的时候,我首先 想到的是北京。
This is the fourth film that has been shown in our school this term. 这是我们校本学期放映的第四部电影。
4. 当先行词为形容词最高级或被形容词最高级修饰时。
如:The best that I could do was to apologize. 我唯一能做的就是赔礼道歉了。
This is the most interesting story book that I have ever read. 这是我读过的一本最有趣的故事书。
5. 当先行词被the very, the only, the last, the just, the same等修饰时。
如: This is the very book that Im looking for. 这正是我在找的书。
The only thing that we could do was to wait. 我们唯一能做的事就是等待。
注意:先行词被the same修饰时,关系代词也可用as。
如:I need the same book that / as you have. 我需要有你一样的书。
6. 当先行词既包含人又包含物时。
如: They are talking of the heroines and their deeds that interest them. 他们正在谈论他们感兴趣的女英雄及她们的事迹。
7. 当先行词是疑问代词who,which,what或主句以这些词开头时。
如:Who that has ever worked together with him doesnt admire him? 曾经和他一起工作过的谁不钦佩他?
Which is the star that is nearer to the earth? 哪个是离地球比较近的星星?
8. 当先行词为主句表语或关系代词为从句表语时。
如:Thats a good book that will help you a lot. 那是本对你很有帮助的书。
Our school is no longer the place that it used to be. 我们的学校现在已不是过去的那个样子了。
9. 先行词为time时,当time表示次数,引导词用that, 可省略。 当表示时间,可用that或when引导,都可省略。
如:I do remember the first time(that) I had ever heard the sweetest voice in the world.我很清楚地记得当我第一次听到世界上最美的声音的时候。
I didt remember the exact time (when/that) I arrived in Shanghai last month. 我不记得上个月到达上海的确切时间了。
