The apartment caught fire last night. Fortunately, most of the people there _______ escape.
A、could
B、tried to
C、meant to
D、were able to
【正确答案】：D
【题目解析】：could 和 was/were able to 在语义上的最大不同在于: could 表达了“能够” 但并未明确指出当时的情景;be able to 表达了“能够”并且实际上反映了当时的情景 ... people there could (get out in time)... people there were able to (get out in time) 读读两句结尾的语气并非全然相同，因此这题正解应该是 D
