◇序数词通常只修饰最高级。
Africa is the second largest continent.
The Yellow River is the second longest river in China.
This is the third most popular song of Michael Jackson.
◇为避免重复,我们通常用that, those, one, ones代替前面出现的名词。that代替可数名词单数和不可数名词,those代替可数名词复数。one既可指人又可指物,只能代替可数名词。
The weather in China is different from that in America.
The book on the table is more interesting than that(或the one)on the desk.
?????? A box made of steel is stronger than one made of wood.
?????? 误:In winter, the weather of Beijing is colder than it of Shanghai.
正:In winter, the weather of Beijing is colder than that of Shanghai.
◇“否定词 + 比较级”相当于最高级。
----Wait until we get a satisfactory reply, will you?
----I couldn't agree more. The idea sounds great to me.
Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing.
◇比较级前一般不加冠词。但表示两者中较突出者,且比较级后又有名词或出现了of the two,这时比较级前一定要加the。
He is the taller of the two.
Of the two jobs,he chose the harder.
Which is the younger one, Lily or Lucy?
试比较:
Which is larger, Canada or Australia?
Which is the larger country, Canada or Australia?
She is taller than her two sisters.
She is the taller of the two sisters.
◇不含than 的比较级前可加不定冠词修饰,构成“a/an+比较级+单数可数名词”表示 “一个更……的人/物”。
Why don’t you use a sharper knife? 你为什么不用一把更锋利的刀呢?
◇比较级than 后应用人称代词的主格,但非正式语体中常用宾格。
He is taller than I/me.
◇为避免重复,比较级中同样的动词用助动词do, does, did替代。
I spend less time doing homework than John does.
She tells more funny jokes than we do.
以下内容不是初中教学的重点,仅供拓展之用。
◇形容词most前面没有the,不表示最高级的含义,只表示“非常”。
It is a most important problem. =It is a very important problem.
◇倍数表达法
▲A is three(four, etc.)times the size(height, length etc.)of B.
The new building is four times the size(the height)of the old one.
这座新楼是那座旧楼的四倍大(高)/这座新楼比那座旧楼大(高)三倍。
▲A is three(four, etc.)times as big(high, long, etc.)as B.
Asia is four times as large as Europe. 亚洲是欧洲的四倍大/亚洲比欧洲大三倍。
▲A is three (four, etc.)times bigger(higher, longer, etc.)than B.
Your school is three times bigger than ours.你们的学校比我们的学校大三倍。
用times表倍数通常用于三倍以上,两倍可以用twice或double.
