题目
题型:不详难度:来源:
-Some people kill tigers and make medicine _____ their bones.
-Yes, it’s terrible, and we can’t wear clothes _________ animal fur.
A.from, made ofB.of, made of
C.into, make fromD.out, make of

答案
A
解析

试题分析:根据语境可知此句的含义是有些人屠***老虎然后用它们的骨头造药。答语是是啊,太残忍了,我们不应该穿动物毛发制造的衣物。此题考查的固定短语be made of和be made from的区别。两者都表示“有…制造”前者表示成品和原材料没有发生化学变化,后者表示成品和原材料发生了化学变化,虎骨和药品之间已发生了很多的变化,故用from,而衣物和动物的毛发没有发生化学变化故用of,故选A。
点评:做此题的关键要分清楚成品和原材料之间的变化,是物理变化还是化学变化。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。
