1、在表达倍数时我们可以用“倍数+as+形容词+as+比较对象”这个结构，如this bridge is three times as long as that one，这座桥是那座桥的三倍长
2、我们还可以用倍数+形容词或副词的比较级+than+比较对象，如this bridge is three times longer than that one
3、我们也可以用倍数+the size/length/weight..+of+表示比较对象的名词，如this bridge is three times the length of that one
4、除了以上三种我们还可以用倍数+that/those of (=as much as ..)如his weight is three times that of mine他的体重是我的三倍
5、在说A的面积是B的三倍大时，我们就可以说，the area of A is three times larger than (that of) B, 也可以说 the area of A is three times as large as that of B
6、以上是几种表示倍数的语法结构，大家在理解它的同时，要多加练习才能熟练的掌握它，掌握了之后不管是阅读还是写作都能在语法上给自己一些帮助
