比较级和倍数表达教学提纲
Ⅰ、no less than不亚于，不亚于，竟达……之多
1)The audience was no less than five thousand. 听众有五千人之多。
2)That hotel probably costs no less than 20 dollars a night. 那间旅馆的住宿费大约要20元一晚呢。
3) He is no less a person than a minister他的身分不亚于部长。
not less than不比……差，至少, 至少和…一样
1) I'll stay here not less than three days. 我将待在这里至少三天。
2) She is not less beautiful than Mary她至少和玛丽一样美丽。
no more than同样不；仅仅，只有
1)He is no more than a worker. 他仅仅是个工人。
2)It's no more than a misunderstanding. 这只是个误会。
3)It is no more than ten minutes' walk from the station. 由车站走到这里只有十分钟的路程。
not more than不比……更，不如；至多
1）He is not more diligent than you are.他不象你那样勤奋。（重点在 you are diligent 。他也勤奋，但不如你勤奋。）
2)I'll stay here not more than three days. 我将待在这里最多不超过三天。
ⅡAs well as
作为习语用作介词时，as well as的涵义是“还有”、“不但…而且…”。值得注意的是，在A as well as B的结构里，语意的重点在 A，不在 B。因此，“He can speak Spanish as well as English．”的译文应该是：“他不但会说英语，而且会讲西班牙语”，决不能译作：“他不但会说西班牙语，而且会讲英语”。如果这样翻译，就是本末倒置了。as well as和not only… but also…同义，但前者的语意重点和后者的语意重点恰好颠倒。
如果 as well as用作连词引出比较从句，其义为“和…一样好”。因此，“He speaks Spanish as well as English．”应译作：“他说西班牙语像说英语一样好”。语意的重点依旧在前部，不在后半部。
请注意 as well as以下的用法：
She called on you as well as I．
不但我来看你，她也拜访了你。
She called on you as well as me．
她不但拜访了我，也拜访了你。
在下列句中，as well as表示“像…一样”的涵义：
She as well as you is an English teacher．
她像你一样也是英文教师。
这里的谓语动词用is，不用are，因为句中的主语是she，不是she和you。
As well是副词短语，其义为“也”，相当于too，它一般放在句末，有时和连词and或but搭配使用。例：
He is a worker，and a poet as well．
他是工人，但也是诗人。
China possesses enormous quantities of coal and is rich in other minerals as well．
中国拥有大量煤炭，其他的矿藏也很丰富。
Mr．Liu can speak English，but he can speak Cantonese as well．
刘先生会说英语，但他也能讲广东话。
Ⅲ英语倍数表达法
用英语表达"A 是 B 的 N 倍长（宽，高，大，重等）"，"A 比 B 长（宽，高，大，重等）N 倍" 或"A 的长度（宽度，高度，大
小，重量等）是 B 的 N 倍"，可用下列几种句型。
1."A + be + 倍数 + as + 计量形容词原级 + as + B".
This tree is three times as tall as that one. 这棵树是那棵树的三倍高。
His father is twice as old as he. 他父亲的年纪有他两倍大。
2."A + be + 倍数 + 计量形容词比较级 + than + B "
The Yangtze River is almost twice longer than the Pearl River.
长江差不多比珠江长两倍。
The dictionary is exactly five times more expensive than that one.
这本字典比那本恰好贵5倍。
3."A + be + 倍数 + the + 计量名词 + of + B "
The newly broadened square is four times the size of the previous one.
新扩建的广场是未扩建时的四倍大。
4."The + 计量名词 + of + A + be + 倍数 + that + of + B "

Ⅳas/so…as用于原级的比较，但在实际应用中，此结构在不同的语境中含义差异较大。现把其用法整理归纳如下，以供读者参考。
1、as/so…as结构的基本模式是：as+形容词/副词+as从句
a.表示不同人或物同一性质的比较，意为“…和…一样…”。
The tree is as tall as the building(is).这棵树和那栋楼一样高。
John is as bright as Bob(is).约翰和鲍勃一样聪明。
上述两例句的否定形式就分别可改为：（so通常用于否定句中）The tree is not as/so tall as the building.
John is not as/so bright as Bob(is).
b.表示同一个人或物不同性质的比较，意为“既…又…”
She works as happily as(she)plays(happily).她愉快地工作，尽情地玩。
