1.英语中,表示“A的大,长,宽等是B的***倍”时,常见的有两种表达法:
(1)A +be+基数词+times +形容词比较级+than B
例句(1):My house is three times bigger than yours.(我的房子是你的三倍大)
例句(2):This pole is twice longer than that one.(英语中,两倍是twice,不用two times)
(2)A+be+times+as+形容词原型+as B
如上面的例句(1)(2)可分别改为:My house is three times as big as yours。 /This pole is twice as long as that one.
自己背啊
序数词是用来表示几分之一的
比如1/3是 one third, 1/4是 one fourth,等等
几倍数有:twice, thrice, quadruple... 或者就是 two times, three times, four times...
time表示倍数,X is 10 times larger than Y。
什么公式啊,你要好好的理解再去背
一、倍数增加
1. A is n times as great(long,much,... )as B.(1)
A is n times greater(longer,more,... )than B.(2)
A is n times the size(length,amount,... )of B. (3)
以上三句都应译为:A的大小(长度,数量,……)是B的n倍或A比B大(长,多,……)n-1倍].
E.g. This book is three times as long as(three times longer than,three times the length of)that one.
这本书的篇幅是那本书的3倍(即长两倍)。
