问题补充：

Farmers in Kaifeng grow a lot of peanuts every year, some of shipped to foreign countries．

A. them

B. which

C. it

D. what

答案：

(答案→)A. them

B. which

C. it

D. what

解析：这题考查独立主格结构，因为ship做动词是及物动词，后面没有宾语的话就要用被动，但这题没有be动词，说明shipped是过去分词，不能做谓语，这句话也就不是定语从句，是独立主格结构做状语，some of them是分词的逻辑主语，句意是：开封的农民每年长了很多花生，很多被用船运到外国。选A。
