问题补充：
What a table! I’ve never seen such a thing before. It isit is long.
A. half not as wide as
B. wide not as half as
C. as wide as not half
D. not half as wide as
答案：
A. half not as wide as
B. wide not as half as
C. as wide as not half
(答案→)D. not half as wide as
解析：句意：好一张桌子！我以前从来没有见过这样的东西。桌子的宽度不到长度的一半。此题考查的是not as…as用法(也可用not so…as)．第一个as为副词，第二个as为连词，表示桌子的宽度不到长度的一半，应用not half，故选D。
