E 吧给出时间段了用完成时比较准确

double 用主动比如 The house has doubled in value since I bought it. 就是加倍的意思

下面是哥prep的例子看看double的用法

In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought its western border within reach of the Pacific Ocean.

(A) In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought

(B) For about four cents an acre the United States acquired, in the Louisiana Purchase of 1803, 828,000 square miles, more than doubling the country's size and it brought

(C) With the Louisiana Purchase in 1803, the United States acquired 828,000 square miles for about four cents an acre, more than doubling its size and bringing

(D) The United States, in the Louisiana Purchase of 1803, for about four cents an acre, acquired 828,000 square miles, more than doubling the country's size, bringing

(E) Acquiring 828,000 square miles in the Louisiana Purchase of 1803, the United States bought it for about four cents an acre, more than doubling the country's size and bringing

sorry...刚刚找到这个题答案是c 看来没有明确的时间状语例如since for之类的不能用完成时，现在想想也是只是说在这段时间里翻了倍，没有完成的必要...误导你了...

那这里谓语动词是DOUBBLE吗，则么感觉more than doubled有些奇怪啊。。。

还有我用increase为什么不可以呢。。。有谁能给我详细的讲讲这个题吗。。。。。谢谢拉
