中学英语要点汇总
1.宾语从句:怎样判断出一个从句是宾语从句?○1 在动词后作宾语(动宾):
Do you know where he es from? 划线部分是动词know的宾语.
○2.在有些接双宾结构的动词后作宾语:
He asked me when we would leave. 此句中me与从句when-分别是ask的宾语。
○3在介词后作宾语(介宾):Let’s talt how we solve this problem.
○4在I’m sorry…, I’m afraid…, I’m sure…等结构后的句子也被认为是宾语从句.
宾语从句需注意的时态问题:
○1主句若是一般现在时,从句根据不同情况用不同时态。
He says (that) he will have a walk soon. (soon指将来,从句用将来时)
The teacher asks who is the cleverest in the school. (暗指目前谁最聪明,从句用现在时)
I want to know who e here late this morning. (今早已过去,从句用过去时)
○2主句若是一般过去时,从句也要用过去时。
He wondered if I would e. She told me that her son had got well.
She said that she liked watching TV. We thought Jim was wrong.
○3无论主句是何时态,从句若表客观真理,要用一般现在时。
Mr. Li said the moon is smaller than the earth.
○4宾语从句无论有何引导词,句子都要用陈述句语序。
Could you tell me when you will get bachan?(不是will you)
Do you know which sweater she is wearing? (不是is she)
2.状语从句:此处所说的状语从句用法仅包括条件(if和unless引导)状语从句和时间(when等引导,见下文)状语从句。状语从句需注意以下问题:
○1主句若是一般将来时、祈使句或含不表过去的情态动词等,则if(如果), unless(除非),when(当…的时候), as soon as(一…就…),before, after, until, till, as(当…的时候)所引导的状语从句用一般现在时。
You may take a rest when you finish doing your work. (主句有情态动词)
Could you look after my son after I leave home?
(情态动词could是为了让语气委婉,并不指过去时,从句仍用一般现在时)
I will go out as soon as it stops raining this afternoon. (主句是将来时)
Wait for your brother at the bus station until he arrives. (主句是祈使句)
○2而主句若是一般过去时,从句也要用表过去时的适当时态,如:
I would give the money to the charity if I had a million dollars.
When he got to the park, his ates had left.
My son ran towards me as soon as he saw me on the street.
3.定语从句:定语从句是指修饰前面名词或代词的句子。从句前面的名词或代词叫先行词,从句中的引导词叫关系代词或哗皮坦关系副词。关系代词who只指人,which只指物。that既可指人又可指物。whose 后必须跟有名词,既指人,也可指物。关系词作主语时,不可省略,作宾语握答时可省略。whom只指人,只作宾语。关系副词where指“在那里”,when指“在那时”。 (以下所给例子乱桐凡斜体字部分均作定语从句。)
She is a girl who / that is beautiful and kind-hearted. The girl who / that is tall is my sister.
(以上关系词作主语,不可省略。)
She is a girl (who / whom / that) I know very well. (关系词做know的宾语,可以省略。)
That boy whose hair is very long is my brother. I own a bike whose price is high.
(关系词whose表所属,后需接名词。前句指人,译为“这个孩子的”;后句指物,译为“这个自行车的”。)
I bought a watch (which / that) I paid 100 yuan for. (指物, 作pay的宾语,可以省略。)
I prefer a place which / that is clean and quiet. (关系词译为“这个地方”,主语,不可省)
I prefer a place where I can live a quiet life. (关系词译为“在这个地方”,是地点副词。)
I shall never forget the day when a boy helped me find my dog. (“在这一天”,是时间副词)4.wish和hope:○1wish既可接to do sth. 也可接sb + to do sth. 也可接that从句.
I wish to spend my summer holiday in Qingdao. I wish you to join my party this Sunday.
I wish (that) I could be a scientist. (注:接that从句时,从句用虚拟语气。)
○2hope接to do sth. 或that从句. 但不接sb to do sth.
I hope to receive a letter from you some day. I hope you will get well soon.
I hope (that) everything goes well. (接从句时不用虚拟)
5.thanks for和thanks to: Thanks for your helping me with the work.
(此句表达对对方为自己做了某事的感谢,后无补充的结果。)
Thanks to your suggestion, I didn’t maistakes.
(此句表达感谢由于某方所做的有利的事,出现了后面的结果。)
6.感官动词用法之一:see, hear, listen to, watch, notice等词,后接宾语,再接动词原形或ing形式。前者表全过程,后者表正在进行。句中有频率词时,以上的词也常跟动词原形。 I heard someone knocking at the door when I fell asleep. (我入睡时有人正敲门)
I heard someone knock at the door three times. (听的是全过程)
I often waty ates play volleyball after school. (此处有频率词often)
若以上词用于被动语态,后面原有动词原形改为带to不定式:
We saw him go into the restaurant. → He was seen to go into the restaurant.
I hear the boy cry every day. → The boy is heard to cry every day.
7.感官动词用法之二:loond, smell, taste, feel可当系动词,后接形容词
