题目

the coat you are wearing today looks nice.what is it___?A.made of B.made in C.made from D.made by
答案是A,可是B不也能说通吗?而且C应该也勉强算对把.（衣服的材料也可以看不出吧.）

答案

made in +地点啊 如：made in China
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.如：
The kite is made of paper．风筝是用纸做的.
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.如：
The paper is made from wood．纸是木头做的.
Butter is made from milk．黄油是从牛奶中提炼出来的.
衣服材料怎么看不出来?原材料在制作中也没发生化学反应.能看出原材料的特征啊
