问题补充:
The newly-built lab is the old one.
A. three times so big as
B. as three times big as
C. three times bigger than
D. three times the size
答案:
A. three times so big as
B. as three times big as
(答案→)C. three times bigger than
D. three times the size
解析:考查倍数的表达:句意:新建的实验室是旧的三倍。这里用的倍数的表达是:倍数+比较级+than的结构,表示倍数的词放在最前面,所以B错误,A错误,因为在肯定句的时候,用as as,否定句的时候采用not so as,D项使用倍数+名词+of的结构,这里少介词of,选C。
