    D

    Tough.


    正确答案： A
    解析：
    推理题。注意题干中的关键词NOT。根据题干定位至原文描述作者母亲的部分，即第四段。该段中作者谈到自己的母亲时说到：…she set a selfless and hardy example.由此可知B和D两个选项是上述两个形容母亲性格的词的同义表达，故不能选。根据该段内容还知，母亲为了生活把作者(长子)当作自己的帮手来维持生计说明母亲是个现实的人，也排除C。并且该段的最后提到：I thirsted for my mother’s attention. … I clearly recall, at the ripe old age of 7, coming to the conclusion that I would never get it.说明作者想要得到的是母亲的关注(attention)和爱(love)，而他永远得不到这些，但这并不是说母亲不爱他，只是母亲不善于表达自己的情感，因此A选项的“善于表达的”并不是母亲的性格。本题为反选题，故正确答案为A。
