36. 倍数句型
1) 增加:
A) A is three times longer than B.
A is three times B.
A is three times as long as B
上述三句话的意思都是：A是B 的三倍（B=1, A=3）。
比较：A is three times longer than B. （B=1, A=3）
A is three meters longer than B. （B=1, A=3+1=4 meters）
Times 是乘号"×"，第一句是"A以3乘以（B）的方式比B长,即：3×1。"第二句的意思是："A以3米的方式比B长，即：3米＋B"
类似的还有：
A has increased (by) three times. A增长了2倍（A以3乘以的方式增长，即：3×基数）。
A has increased by 300％. A增长了300%（A以300%方式增长，即：300%×基数＋基数）。
但：
A has increased to 300％. A增长到了300％。(A=300%)
2) 英语中的倍数减少
汉语中，倍数不能说减少。因此，英语说减少了n倍，等于汉语还剩1/n (n分之一)。
A has dereased by three times. A减少到了3分之1。
A has dereased by 1.2 times. A减少到了6分之5 (A减少到了1.2分之1，即12分之10，约分为6分之5)。
