The shoes are made leather and are suitable going for a walk.
A. from; of
B. of; to
C. from; to
D. of; for

A. from; ofB. of; toC. from; to(答案→)D. of; for解析：be made of和be made from都表示“由……制成”，主语为制成品。 1.be made of 表示制成成品后，仍可看出原材料是什么，保留原材料的质和形状，制作过程仅发生物理变化。2.be made from 表示制成的东西完全失去了原材料的外形或特征，或原材料在制作过程中发生化学变化，在成品中已无法辨认。be suitable for sth 适合于……的，后面接名词；be suitable to do sth.适合于做,后面接动词。句意：这双鞋是皮制的，适合于去散步。结合语境可知选D。

这个问题我还想问问老师呢
