英文倍数的表达方式，是日常生活中比较常用的。所以在初级英语教学中都会教授这些知识点。下面小编告诉你英语表示倍数的方法，大家一起来看看吧!
英语表示倍数的方法:
1. 倍数 + as + 形容词或副词的原级 + as + 其他。
这种结构又常演变成下列两类:
①倍数 + as + many + 可数名词复数 + as;
②倍数 + as +much + 不可数名词 + as。如:
There are seven times as many people as I expected.是我预料的人数的七倍。
There is five times as much coffee in this glass as in that one.
这个杯子里的咖啡是那个杯子里的五倍。
2. 倍数 + 形容词(或副词)的比较级 + than + 其他。如:
The hall is five times bigger than our classroom. 这个大厅的面积比我们教室大五倍。
3. 倍数 + the size / height / length / width. etc. + of + 其他。如:
This road is six times the length of that one. 这条路是那条路的六倍长。
4. 计量名词 + of + 名词 + be +倍数 + that + of + 其他。如:
The size of the newly broadened square is four times that of the previous one.
新扩建的广场为以前的四倍大。
5. 倍数+what从句。如:
The production is now three times what it was ten years ago.现在的产量是十年前的三倍。
6. 倍数 + more + 名词 + than +其他。如:
There are nine times more books in his bag than in yours.
他书包里的书比你书包里的书多九倍。
7. 其他表达。如:
She’s twice/ double my age. 她的年龄是我的两倍。
The average income of the staff has been increased by 50 percent compared with last year.
与去年相比，该单位职工的收入已增加了50%。

英语中表示倍数减少的表达方法:
(一)a is n times as small (light，slow，…)as b.
a is n times smaller (lighter， slower，…) than b.
以上两句均应译为:a的大小(重量，速度，……)是b的1/n[或a比b小(轻，慢，……)(n-1)/n]。
. The hydrogen atom is near1y l6 times as light as the oxygen atom. 氢原子的重量约为氧原子的1/16(即比氧原子约轻15/16)。
. This sort of membrane is twice thinner than ordinary paper. 这种薄膜比普通纸张要薄一半(即是普通纸厚度的1/2)。
注:当相比的对象b很明显时，than/as b常被省去。
(二)decrease n times/n--fold
decrease by n times
decrease by a factor of n
以上三式均译为:减少到1/n[或:减少(n-1)/n]。
decrease常被reduce，shorten，go/slow down等词替代。
. Switching time of the new-type transistor is shortened 3 times. 新型晶体管的开关时间缩短了1/3(即缩短到2/3)。
. When the voltage is stepped up by ten times, the strength of the current is stepped down by ten times. 电压升高9倍，电流强度便降低9/10(即90%)。
. The equipment reduced the error probability by a factor of 5. 该设备误差概率降低了4/5。
(三)there is a n-fold decrease/reduction… 应译为:减至1/n [或:减少(n一1)/n]。
这个句型还有其它一些形式，
. A rapid decrease by a factor of 7 was observed. 发现迅速减少到1/7。
. The principal advantage of the products is a two-fold reduction in weight. 这些产品的主要优点是重量减轻了1/2。
学好英语的方法:
1.多方位多角度来学英语。要经常读报、听广播、看外语电影、听外语讲座、读课本和别人交谈等方式来学英语。
(Learn English in different ways. Read newspapers, listen to the radio , watch English movies, listen to English lectures, read textbooks and talk with each other ect.)
2.方法要灵活多样。一种方式学厌了，可以变换其他的方式，以便学而不厌。
(Different kinds of ways to learn English. One way is boring, you can use other ways, so that you won't feel bored.)
3. 坚持不懈，从不间断。每天至少看 10-15 分钟的英语，早晨和晚上是学英语的最好时间。
(Never give up, keep working on. Speak English at least 10-15 minutes every day. The best time to learn English is in the morning and the evening.)
4.熟记常用语，确保准确无误。把常用的交际用语背熟，俗能生巧。
(Remember useful expressions, and make sure it's right. Practice makes perfect.)

6.尽量用第一人称来记习惯用语和句型，以便记忆牢固。
