翻译:A is twice as many as B.

倍数的表达结构是:A + 动词+ 倍数+ as +adj./adv. +as + B。

一、twice

1、含义:adv. 两倍;两次。

2、用法:

直接源自古英语的twiga,意为两次。

twice的意思是“两倍,两次”,在句中可修饰静态动词、动态动词,也可修饰形容词、名词、数词或其他副词。

The length of the table is twice its breadth.

桌子的长度是它的宽度的两倍。

二、as many as

1、含义:和 ... 一样多。

2、用法:

as many as 修饰可数名词。as many as 常用在人或物的具体数量前,侧重于具体数目,意思是“和……一样多”,“多达……”。

As many as 100 people were killed in the air crash.

这次空难中多达一百人丧生。



as many as临近单词:

as

一、含义:

adv. 同样地;例如;被认为。

prep. 作为;如同。

conj. 因为;像;当 ... 之时;像 ... 一样;结果;尽管。

n. 阿斯(古罗马重量单位,约373克;古罗马铜币名。

二、用法:

as用作副词时主要用来表示比较,意思是“像…一样;如同”。可以单独使用,但更多的是用在as...as结构中,其中第一个as是副词,其后可接形容词或副词,也可接其他成分,as前可有状语。

第二个as可以是介词,也可以是连词。as用作副词时还可以指事物以同样的方式发生,意思是“和…一样”。

as还可表示原因,作“因为,既然”解,引导原因状语从句,表示不说自明的原因或理由,语气较轻,是附带提及,不加强调。as引导的从句可放在主句之前(表示原因不明显),也可放在主句之后(表示原因明显)。

The ground was as white as snow with petals that had drifted down from the apple trees.

满地是苹果树上飘落下来的花瓣,地上一片雪白。



twice as many A as B是A是B的两倍。

many

读音:英[ˈmeni] 美[ˈmɛni]

词类:adj. 许多,多的。
pron. (与复数动词连用) 大多数人;可数; 修饰可数名词;多少。

例句:I don't think many people would argue with that.

我认为多数人不会对此有异议。

many和many a的区别为:指代不同、用法不同、词性不同

一、指代不同

1、many:(与复数名词及动词连用,尤用于否定句或正式用语,表示大量。

2、many a:许多。

二、用法不同

1、many:many用作形容词时后接复数名词,表示许多同样的人或物(但数目不明确),用作主语时,其谓语动词要用复数形式。

2、many a:many用作代词时,作“许多,许多人”解,常用于many of...结构中,谓语动词须用复数。many或a good〔great〕 many用作主语时,其谓语动词用复数。

三、词性不同

1、many:是形容词性单词。

2、many a:是不定冠词词组。



倍数不一定要注意倍数放在as....as的前,twice as many A as B是正确的用法,就是A=2B 的意思。

倍数的表达其实很简单。

结构是:A + 动词+ 倍数+ as +adj./adv. +as + B A是B的2倍。

the tree is twice as tall as the house. 这颗树是房子的2倍高。

He runs three times as fast as her. 他跑步是她的3倍快。

一定要注意倍数放在as....as 的前面。

注意

基数词 1-12 是独立单词,需逐个记忆。

基数词 13-19是个位数词的词干后加-teen 构成。其中 thirteen, fifteen, eighteen 变化不规则。

基数词 20-90 是在个位数词后面加 -ty 构成。其中 twenty, thirty, forty, fifty, eighty 变化不规则。

基数词 21-99 是在十位数词后面加上个位数词合成,中间加上连字符 " - " 。

以上内容参考:百度百科-数词
