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)。
