B、the word order cannot be inverted or changed
C、the various words that make up the idioms have lost their individual identity
D、the constituents of an idiom cannot be deleted or added to, not even an article
【正确答案】：B
【题目解析】：本题考查习语结构的稳定性。习语的稳定性包括：1.习语的组成成分不可替换the constituents of idioms cannot be replaced （in a brown study）；2.习语的语序不能倒装或改变the word order cannot be inverted or changed（by twos and threes；the lion's share）；3.习语的组成成分不能删除或增加，哪怕是一个冠词the constituents of an idiom cannot be deleted or added to, not even an article（out of the question）；4.很多习语在语法上是不可分析的many idioms are grammatically unanalysable（diamond cut diamond）。而题干所说的The lion's share不能被the share of the lion所替换属于第2条。故B选项符合题意。
