答案：
(答案→)A
解析：
【主旨大意】你也许听过这种表达，“It’s raining cats and dogs outside．”它并不是猫和狗从天上掉下来，但是却发生了青蛙石落在地上的事实。
【小题1】这里是需要引导宾语从句，且在从句中不做成分。句意:它意思是天正在下大雨。A项符合题意。
【小题2】根据上下文判断那并不是真猫和狗落下来。careless粗心的；无忧无虑的，blind失明的；盲目的，dead死去的， real 真的；现实的，故选D。
【小题3】根据下文提示可知是，故选C。
【小题4】根据下文判断可知是frogs，故选B 。
【小题5】根据句意应是青蛙随着冰雹开始降落，故选C 。
【小题6】根据下文判断是一场可怕的风暴，故选B 。
【小题7】根据句意应是雨点被强风抓住，故选D。
【小题8】根据句意应是雨点冻结在一起形成冰球，故选A 。
【小题9】根据句意应是这些冰球或冰雹，然后下降到地球，故选 D 。
【小题10】从…进入…用from… into…，故选B。
