参考答案

正确答案：A
解析：成千上万的人无家可归可是这些楼却空无一人, 这真让人难以接受。unacceptable令人难以接受, 如：If a thing is not done to perfection, it is unacceptable．做得不完美的事是无法接受的。unreasonable不合情理, 如：This price is unreasonable at all．这个价钱一点也不合理。disgusting令人厌恶和恶心的, 如：There is a disgusting smell near the ditch．水沟附近味道很难闻。courageous勇敢的, 如：It was courageous of him to oppose his chief．他敢反对他的上司, 真是勇敢。只有unacceptable意思上和outrageous最接近。
