据专家权威分析,试题“句型转换。1. Mary was able to find the way back home. (改为..”主要考查你对 从属连词,不定式,一般过去时,一般疑问句,疑问词组 等考点的理解。关于这些考点的“档案”如下:
从属连词不定式一般过去时一般疑问句疑问词组
考点名称:从属连词
- 从属连词:
这种连词是用以引导名词性从句定语从句和状语从句的,由从属连词所引导的句子叫从句,而含有从句的句子叫作复合句。 从属连词可分为三大类:
1、that (无词义,不做成分)
if,whether (表达是否的意义,但不做句子成分)
2、连接代词:who,whom,whose,what,which,whatever, whoever, whichever(有词义,在句子中可作主语、表语、宾语)
3、连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语)用法:
从结构上说,英语连接词分两大类:并列连词和从属连词。
并列连词连接两个或两个以上地位平等的字、词组或分句。例如:
(1) Air and water are indispensable to me.
(2) She likes going out with friends or playing outdoor games.
(3) Most workers have a good income, so they look very happy.
从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如:
(4) He said that he did not want to go .
(5) Many things have happened since I last saw him.
(6) You may come if you want to.
从属连词用来连接各种从句。
until(till)直到,在用until表达时间状语的句子中,主句中的动词是要十分小心去选择的。
如动词是持续行动词,它要用肯定句,如:
I studied hard until 12 o'clock last night.
如果动词是瞬间截止性动词,则要用否定句,如:
He didn't go to bed until his mother came back.
由since,for,by,before, 来引导的时间状语从句。
since 引导的时间状语是动作的开始时间,如:
I have studied English since 1990.
而by引导的时间状语通常是动作的结束时间,如:
I had learned 25 English songs by the end of last term.- 从属连词语法分类:
种类 语法作用 连词举例 从属连词 引导原因状语从句 Because, since 引导条件状语从句 If, unless, as long as 引导目的状语从句 So that 引导结果状语从句 So…that 引导方式状语从句 As, just as, as if 引导让步状语从句 Though, although, even
though, no matter what,
however, no matter how,
whoever, no matter who,
wherever, no matter where引导比较状语从句 As…as, not so…as, than,
less…than, the more…the
more引导名词性从句 Who, whom, whose, which,
that, when, where, why
考点名称:不定式
- 动词不定式:
指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。
动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。 - 动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
这一使动者我们称之为逻辑主语,其形式如下:
时态 主动形式 被动形式 一般式 (not) to do (not) to be done 完成式 (not) to have done (not) to have been done 进行式 (not) to be doing 完成进行式 (not) to have been doing - 不定式的用法:
1、不定式作主语
例如:To remember this is very important.
注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
例如:It is very important to remember this.
2、不定式作表语
例如:He seems to be ill.
注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
三是表示想法、约定、义务、命令、可能性、命运等,如:
You are to come when I call.
3、不定式作宾语
例如:I can not afford to buy a car.
注意:
①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
例如:I had no choice but to wait.
②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
例如:I find it difficult to learn Japanese well.
4、不定式作宾语补足语
例如:Who taught you to drive?
5、不定式作定语
例如:I have a question to ask you.
注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
