题目

—When did it begin to snow? —It started        the night. A.during                      B.by                                   C.from                         D.at 答案：A 解析: A项 during the night的意思为“在夜里的某个时间”，同in the night。如选B项，常用by night。如：a tour of Paris by night夜游巴黎；C项from the night既不符合习惯用法，又不指准确时间。若选D项应为at night。
