参考答案

正确答案：B
解析：事实细节题。第二段提到了Blake的两个室友。第二句指出：Two friends，one a little Frenchman and the other a big Dane，shared it with him，both hoping eventually to contribute something towards expenses，but so far not having accomplished this result．这表明他们打算分担房租的想法没有实现，排除A ；第三句指出 They had two beds only，the third being a mattress they slept upon in turns，a week at a time，倒数第三句中的made a wild race for bed的目的是后面提到的让假的吃饱了的感觉还存在之前入睡，并非为争夺床位，排除C 。这里也说明了他们有时是饿着上床睡觉的，选项B 符合文意，故为答案。末句指出Fortunately a11 New York houses are supplied with hot air，and they only had to open a grating in the wall to get a plentiful，if not a wholesome amount of heat．这说明虽然有时候挨饿，但还不至于受冻，排除D 。
