问题 In 1980 the United States exported twice as much of its national output of goods as they had in 1970.
选项 A、twice as much of its national output of goods as they had
B、double the amount of their national output of goods as they did
C、twice as much of its national output of goods as it did
D、double the amount of its national output of goods as it has
E、twice as much of their national output of goods as they had
答案 C
解析 首先应补出比较后的对应物it(they是错的)，排除A、B、E；C、D比较，根据补出谓语动词的原则，应用did(in 1970)，用has是错的，选C；同时B、D中明显错误double是动词，意即“使…翻倍”，而名词两倍应用twice；B、E中their指代错。
