问题
All of the plants now farmed on a large scale were developed from plants________wild.
选项
A、that once grew
B、once they grow
C、they once grew
D、once grew
答案
A
解析
现在大规模种植的所有植物都是从曾经的野生植物进化而来的。定语从句题。该句第一个plants后面接的是过去分词短语now farmed on a large scale作定语;第二个plants后面接的是定语从句,需要有关系代词that来作主语,且that不可省略。B、C项选项里都用了they作主语,是语法错误;D项选项里缺少了主语,句子不正确。所以A项为正确答案。
