改来改去，其实就是C这个答案。

llei

如果用increase 或two times应该怎么说，　b不对吗？

按照og的解释, b的意思不清楚, 到底是说数量多了两倍, 还是两次的意思

- an area twice the size of Britain
- Within two years the company had doubled (tripled)    in size

在表示两倍，三倍和四倍时最简洁和effective的说法分别是double, triple和quadruple, 似乎ETS在出现诸如increase by two times时都会将之改成double
