Question

Books are made _____paper and paper is made _____ wood and bamboo
A. from, from       B. of, of       C. of, from

Answer 1

C

試題分析：be made of,be made from的意思都是由……組成，be made of 是可以看出原材料的,be made from是不可以看出原材料的,而題中第一空書是由紙做的，可以看出原材料的，故用be made of;第二空紙是由木頭和竹子做的，看不出原材料，故用be made from，
故選C
點評：除了這兩個常考短語外，補充一個be made in +地點
