大学英语：The Atlantic Ocean is only half as big as the Pacific,…

　　在第一单元中我们讨论过副词的同等比较。本句中as big as 则是形容词的同等比较。在这类句子中，可以有表示程度的状语。例如：

　　1) This book is not half as interesting as that one.（这本书还不如那本书一半有趣。）

　　2) My monthly income is only half as much as his.（我的月收入只有他的一半多。）

　　3) This year our university will enroll three times as many students as it did the year before last.

　　（我们学校今年的招生人数将是前年的三倍。）

　　请翻译下面的句子：

　　1) 我的英语口语还不及你的一半流利。(My spoken English is not half as fluent as yours.)

　　2) 这只手提箱还没有那只手提箱一半重。(This suitcase is not half as heavy as that one.)

　　3) 这个房间是那个房间的两倍。(This room is twice as large as that one.)
