问题 In manufacturing, cheaper materials are constantly being _________ for the more expensive kind.
选项 A、replaced
B、transcended
C、transplanted
D、substituted
答案D
解析 近义词辨析。transcend 意为“超出，超越”，如：One never can see the thing in itself，because the mind does not transcend phenomena．(一个人永远不可能认识事物自身的本质，因为思想无法超越现象。) transplant 意为“移植，移栽”，如：transplant the flowers to the garden (把花移植到花园里)；replace 与 substitute都有“替代，替换”之意，但两者用法不同：replace sth．with/ by sth．和substitute for sth... 如：replace coal by/ with gas (用煤气代替煤作燃料)；substitute for a teacher (代替一位教师)。根据句意和搭配，应选D)。
