大权153 清牛牛分析！

1.        At the time of the Mexican agrarian revolution, the most radical faction, that of Zapata and his followers, proposed a return to communal ownership of land, to what had been a pre-Columbian form of ownership respected by the Spaniards.

(A) land, to what had been a pre-Columbian form of ownership respected by the Spaniards

(B) land, a form of ownership of the pre-Columbians and respected by the Spaniards

(C) land, respected by the Spaniards and a pre-Columbian form of ownership

(D) land in which a pre-Columbian form of ownership was respected by the Spaniards（A）

(E) land that had been a pre-Columbian form of ownership respected by the Spaniards

清分析这句结构以及如何排除其他的！谢谢先！

A) best. 引入介词to清楚地表明communal ownership of land is what had been a pre-Columbian form of ownership respected by the Spaniards.我把这种结构还是看成同位语。同位语是ETS喜欢的形式。

B) a form of ownership of the pre-Columbians and respected by the Spaniards，and前后不平行。
C) 同上。
D) in which修饰land改变意思。
E) 原认为是：that可能给人感觉修饰land造成错误的意思。现不是很满意这个解释，只能凭感觉这里用that限定性修饰不如A清楚。
