第03期 倍数表达法
题目回顾
Staying in a hotel costs ____ renting a room in a dormitory for a week.
A. twice as much as
B. twice as much
C. as twice much as
D. as twice as
此题正确答案是A,你选对了吗?
分析句子结构:该句子的主语是staying in a hotel, 意思是待在酒店,是个动名词做主语的结构,谓语动词cost花费,后面是as…as方式状语从句,像…那么多。
句子翻译:住酒店一周的花费是在宿舍租房的两倍。
分析考点:该题考查表达倍数的方式,倍数+as+形容词副词原级+as+比较对象,意为…是…的几倍。即把表示倍数的词twice,three times等放在第一个as之前,修饰副词much(多),第二个as后rentinga room in a dormitory,是比较对象。
分析其他选项:B选项缺少一个as,C选项twice倍数放在as前,D选择twice放在as前,且缺少形容词或副词
知识梳理

e.g. Thenewly-build railway station is two times larger than the old one.
新建的火车站比旧的大两倍。
