3.比较等级的一些特殊用法

3.1两种不同形式

有几个形容词和副词的比较级和最高级有两种的比较等级不同形式,而且意义也不同。
举例说明:
1)Rome is one of the oldest cities in the world. 罗马是世界上最古老的城市之一。
Her eldest daughter is a school teacher.她大女儿是个教员。
My elder brother is in college. He is two years older than I. 我哥哥在上大学,他比我大两岁。
[注]older,oldest说明人的年纪或事物的年代的久远,但在美国英语里也表示长幼。

2)They reached the place later than we.他们到达那儿比我们晚。
Twenty years later he returned to his home village. 二十年后,他回到自己的家乡。

3)Who spoke last?是谁最后发言的?
What is the latest news about the sports meet?关于运动会最近有什么消息?

3.2 as...as;not so. . .as或not as...as

1)表示"相等"用as...as。如:
This knife is as sharp as that one.这把刀跟那把一样快。
Bill is as tall as I. 比尔和我一般高。
Is this bag of soyabeans as heavy as that one?这袋大豆跟那袋一样重吗?
You know as well as I do.你和我一样明白。

[注]注意as后面的形容词如作定语,而被定语修饰的名词有不定冠词a时,冠词a须放在形容词之后,如German is as difficult a language as English.(德语和英语一样难学。)。这样的词序也适用于so,如I have never seen so beautiful a place as Guilin before.(我过去从未见过像桂林这样美丽的地方。)

2)表示"不相等"用not so...as或not as...as。如:
Tian An Men Square was not so big as it is now.天安门广场过去没有现在这样大。
The Atlantic Ocean is not as big as the Pacific ocean.大西洋没有太平洋大。

3.3表示"几倍于"
用twice (两倍),three times(三倍)等加as...as..
如:
New York is ten times as big as my home town.纽约有我的家乡十个大。
The output of the paper mill is now three times as high as it was in 1966.这家纸厂的生产比一九六六年增加两倍。
This river is twice as long as that one.这条河比那条河长一倍。
Asia is four times as large as Europe.亚洲比欧洲大三倍。

[注]表示"几倍于"也可以用下面的说法,如:

Three times three is nine.三乘三得九。
He is twice my age.他的年龄比我大一倍。
This lake is four times the size of that one.这个湖有那个湖四个大。
The irrigated area in this province is four times bigger than in l978.这个省的灌溉面积比1978年增加三倍。(four times bigger than = four times as big as)
Our county's agricultural output this year is 5 per cent higher than that of last year.我们县今年农业产量比去年增长百分之五。

3.4表示程度
可用much,far,still,even,a 1itt1e,no,any,a great deal等状语来修饰形容词和副词的比较级。如:
The Yellow River is long,but the Changjiang River is even longer.黄河长,长江更长。

He is a head taller than I.他比我高一个头。(也可以说He is taller than me by a head.)

Swimming in winter is the best form of exercise imaginable.冬泳是最好的运动方式。(也可以说the best imaginable form)

(后面不可接than从句)可用来表示"越来越"。如:
The days are getting longer and longer.白天越来越长了。

The more the more 的用法
意思是"越…,就越…"。如:

He is no more diligent than I am.他和我同样不勤奋

4)no less than和not 1ess than
no less than的意思是"不亚于",not less than的意思是"不少于"。试比较:
There were no less than a thousand people at the meeting.
到会的有一千人之多。(有"到会人多"的含义)
There were not less than one thousand people at the meeting.
到会的至少有一千人。(没有"到会人多或人少"的含义)

This song is not less popular than that one.这首歌受欢迎的程度不比那首差。(纯粹比较。不一定有"两首歌都受欢迎"的含义)

这一类的说法都有"因此而更…"的含义。如:
