语法检测-用英文表示比较
编辑：pitaya02 日期：2020-12-15
比较表达是英文中的一个难点，给许多同学造成困难。今天陈老师想把这件事弄清楚。假如文章对你有用了麻烦就点赞，没有用的话也别怪我，再搜别人的文章看看，谢谢。
用英文表示比较火龙果智能语法检测
1-倍数比较
其中最常用的倍数表示法如下：
“… times+ as+形容词/副词原级+ as…”或
times+形容词/副词比较级+ than…
“… times+ the+名词(例如： size、 height、 weight、 length、 width、 age等)+ of…”
这个看起来很复杂，实际上捋一捋就明白了，首先列出比较主体 A，然后给出倍数，两者都是常量。接下来是内容的比较，通常是比尺寸，比身长，比重量等等。在英文中，与尺寸、高度和重量有关的词有两类：修饰词(形容词/副词)和名词。举例来说，在进行比较时，不同的人脑的第一反应是不同的，有些人的第一反应是更直观的形容词 big (bigger)/small (smaller)等等，有些人的第一反应是名词“smaller”。因此，英文中最常见的比较表达方式有以上两种。
若比较内容为名词性，则结构较单一：
A+ B+主体倍数)+(the size/height/weight of B)
the size of the moon, The earth is 49 times.地球的体积是月球的49倍。
这条河比那条河深3倍，河水深可达3倍之多，所以它的名字叫 This river is three times the depth。
this street is four times the length of that street.它比那条街长4倍。
若比较内容为形容词性或副词性，则结构相对复杂一些，有时使用原层次，有时使用比较层次：
A+ be+主体倍数)+ as/同样... as/和 B
A+ B+ BB)+ more/更... than/比 B主体更强
但是不论此时使用原始级别还是比较级别，表达的意义是相同的：
亚洲比欧洲大四倍。火龙果智能语法检测
Asia is four times as large as Europe.
Asia is four times larger than Europe.
看起来很矛盾，实际上并非如此。其原因是：使用 as large as的人将亚洲面积与乘以4之后的欧洲面积进行比较，两者相同，因此使用了原始层次；使用 larger than的人将使用 larger than之前的亚洲和欧洲面积进行比较，两者存在差异，因此使用了比较层次，角度不同。想想，外国人的数学那么差，怎么能自己围着自己转？很久以前，他们就把倍数放在首位。
1.A is 3 times as long as B.
2.A is 3 times longer than B.
3.A is 3 times the length of B.
意义相同： A比 B长三倍。
其他倍数表示的结构大抵也可以这样来理解，例如，比较名词数目时常用的结构：
"… times+ as many/much+名词+ as…"
两种结构所表达的意思相同，即“… times+ more+名词+ than…”比如：
He earns five times as much money as he did ten years ago.
He earns five times more money than he did ten years ago.
目前他赚的钱是10年前的5倍。
2.百分率比较
若与分数、百分进行比较，则两个比较主体在人脑中不易达到“平衡”，因此，一般采用比较级而不采用原始级：
The box is one-third bigger than that one.
这只箱子比那只大三分之一。
Last year the output value of industry was 59 percent higher than that of 1976.
与1976年相比，去年工业生产增加了59%。
一定要注意，整数百分数也是百分数，用来表示倍数的逻辑与其他百分数的逻辑基本相同，而且与英文倍数的逻辑有所不同：
A is 300% longer than B.
a比 B长300%。
完全对应的英文中文，用倍数来换算并不容易出错，也就是说 A比 B长4倍。
概述：
要了解英文的比较表达，首先要弄清楚两类英文结构：
在英文中，同级结构为 as adj/adv+ as...，比较级结构为 more... than...，这一结构相信很多读者都能理解：
The tree is as tall as the building．
The tree is taller than the building．
He earns as much money as he did ten years ago.
He earns more money than he did ten years ago.
复合倍数：
The tree is twice/three times as tall as the building．
The tree is twice/three times taller than the building．
He earns five times as much money as he did ten years ago.
He earns more five times much money than he did ten years ago.
好了，再说一遍，很简单吗？因此，在书写比较表达时，不妨先写出简单的比较结构，再加倍或百分法。最终要注意的是，倍数表达需要用英语思维来理解(只看倍数，不用计算)，百分数表达可以直接用中国式思维迁移(需要真的去计算)。火龙果智能语法检测
若做选择题，则需要转换思路，先对问题进行分析，然后进行结构简化，例如：
（ 2002 上海春） Americans eat ________ vegetables per person today as they did in 1910.
A. more than twice
B. as twice as many
C. twice as many as
D. more than twice as many
想法：先求 twice，再求 as.... as结构，题干后再求 as已有，故选 D。火龙果智能语法检测
