【正确答案】 B

【答案解析】此题属于语法题。be worth+ 名词/doing 意为“值得…”，此处的名词往往是钱数或相当于代价的比喻性名词，例如：It's worth the time and effort we devoted to it 另外， worth 后面的动名词总是用主动的形式表达被动的意思，例如：It is worth considering．故选项[B] worth 与living 连用，符合题意。选项[A] worthy 意为“值得”，“be worthy of+名词/to do，例如：This novel is worthy to be ranked among the masterpieces of Chinese Literature．/It is worthy of the name．选项[C] worthless 意为“无价值的”，与句意不符；选项[D] worthwhile 意为“值得的”，作表语或定语，例如：It was a worthwhile attempt even though it failed to achieve its aim．
