计量的表达方法可以是:
基数词+度量词(单/复数)+形容词(high/old/long/wide/tall/deep/thick等)。
比较级用于比较两个主体,之后可用than引出比较的对象
“比较级+than any other+名词(单数)+其他”
表示“比其他任何一个……都……”
该结构可与“the+最高级+其他”相互转换
The is .
e.g. The basketball player is 2 meters tall.
The river is about 2 meters wide/deep.
The mountain is about 2 thousand meters high.
The river is about 2 kilometers long.
长、宽、高、深的表达法: 基数词+度量词+形容词(long, wide, high, deep等)。当基数词大于1时,度量词用复数形式。
重难知识点归纳
Qomolangma is higher than any other mountain in the world.珠穆朗玛峰比世界上其他的山都高。
“比较级+than any other+可数名词单数” 意为“比其他任何一个……都……”,指同一范围内的比较,相当于“比较级+than the other+可数名词复数”。
e.g. Shanghai is bigger than any other city in China.
上海比中国的其他任何城市都大。
【注意】
如果比较对象不在同一范围内或不属于同一类别,应用“形容词/副词比较级+than any+可数名词单数”。
e.g. Shanghai is bigger than any city in Africa.
上海比任何一个非洲城市都大。(上海不属于非洲)

by weight按照重量(计算或出售)

倍数的表达法
“倍数+比较级+than”表示“……比……(大/小/长……)几倍”。
e.g. This table is three times longer than that one.
这张桌子比那张桌子长三倍。
【拓展延伸】 “倍数+as+形容词+as”表示“……是……的几倍”。
e.g.This table is three times as long as that one.

When the babies see the keepers,they run over to them with excitement and some of the young pandas even walk into their friends and fall over!当大熊猫幼崽看到饲养员的时候,它们兴奋地跑向他们,其中一些年幼的大熊猫甚至撞上自己的伙伴而跌倒!
excitement是不可数名词,意为“激动;兴奋”。
常用短语有:
with excitement=excitedly=in excitement兴奋地
to one's excitement令某人兴奋的是
【易混辨析】excite,exciting与excited

e.g.I saw a boy fall over in the park yesterday.昨天在公园里,我看见一个男孩跌倒了。
【易混辨析】fall down,fall off与fall over
