选择D

这是表示倍数的句型

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].

如:

1. 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).

注:当相比的对象B很明显时,than(as,of)B常被省去.
