标题: 大全356
356.In 1980 the United States exported twice as much of its national output of goods as they had in 1970.

(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

(D) double the amount of its national output of goods as it has（C）

(E) twice as much of their national output of goods as they had

想借此题请教一下twice和double有区别？二者皆可用作adj和v，而且在词典中常互相解释。。

see Tonyadidas 一些语法总结

2. 比较的原则

d.倍数表达法twice as many as/twice the n/twice what/sth double（出现即正确）/sth be doubled（被动不好）

我的思路：首先排除A，B，E，因为包含了错误的they,their之类；
其次，可以排除D，因为double the amount of its national output of goods as it has，最后使用了has,而省略应该使用did来代替前面的动词，而非要使用实意动词，那么应该补全所有的部分

什么地方都注意到了，但是总是判断错误，怎么办呢？把united States当做复数了，所以选了B.......然后看到注释里面写easy~~~直接晕过去了
