专题02 中考易混淆知识点辨析
1. “如此….以至于…..”句式的两种表达:so that与such that的区别
①so后面+adj./adv, 而such后面+名词/名词词组(名词词组:可数名词单数/复数/不可数名词)
例如:He runs so fast that I can’t catch up with him.
The man ate such a big apple that he didn’t want to eat dinner.
②当名词前面有much,many, few, little修饰的时候,需要用so
【特别注意】当little表示“小”的时候,需要用such; 而little表示“少”时用so
例:such a little bird如此小的一只鸟 such little fish 如此小的鱼
so little food 如此少的食物
2.代词it/one/that/those的用法
①it指代同类同物,即前面提到的人或者事物,属于同一个人或者事物。
例:I have lost my umbrella; I’m looking for it. (it指前面的雨伞)
②one指代同类异物,即前面提到的同类但是不是同一个人或者同一个事物,表示一种泛指,相当于不定冠词a/an+名词
例:I have lost my umbrella; I think I must buy one. (同类不同物)
③that也指代同类异物,但是特指,相当于定冠词the+名词单数/不可数名词。
例:The umbrella you bought is cheaper than that I bought.
The weather in the USA is much more changeable than that in the UK.
④those也指代同类异物,但是特指,相当于定冠词the+名词复数。
例:The umbrellas you bought are cheaper than those I bought.
3.宾语从句
①宾语从句语序必须为陈述句语序
【特别注意】以下句式也属于陈述语序:
1)what’s wrong with sb?/what’s the matter with sb?
2)what happened to sb?/what is happening to sb?/ what has happened to sb?
3)which is the way to the school?
4)what your name is?
②宾语从句的连接词if/whether表示“是否”,一般选择whether比较正确,而that用于陈述语气的句子当中。
【特别注意】I doubt whether/if……..(肯定句)
I never doubt that……….(否定句)
③时态考点
(1) 若主句是一般现在时,从句该用什么时态就用什么时态。
例:He says Mary often plays with the cat at weekends
He says Mary will play with the cat this weekend.
(2)若主句是过去时,从句用一般过去时,过去进行时和过去将来时
例:He asked me what time it was.
He said that he would go back home soon.
He said that he was watching TV at 6 o’clock yesterday.
【特别注意】如果从句表示的是某种客观真理时,从句只能用一般过去时,不需要看主句的时态。
例:Mr. Smith told me that the Earth travels around the Sun.
I was told that light travels faster than sound.
4.How long/soon/far/often的用法
①how long:指多长时间,主要用来对一段时间(如three days, four weeks 等)提问
②how often指每隔多久,主要用来对频度副词或状语(如once a week等)提问
③how soon指再过多久,主要用来对表示将来的一段时间(如in an hour, in two weeks )提问
④how far指多长距离,主要对表示具体两地距离的提问
5.Live,lively,alive,living的用法区别
1) alive 意为“活着”,侧重说明生与死之间的界限,既可指
