单选题
If the ocean were free of ice, storm paths would move further north, ______ the plains of North America of rainfall. A. to deprive B. deprived C. depriving D. deprive
【正确答案】
C
【答案解析】此题的测试点为分词的句法功能。本句中depriving the plains of North America of rainfall作storm paths would move further north的伴随状语，表明两种情况同时发生。表示伴随，只能用分词形式。句意为：“如果海洋表面不结冰的话，风暴的线路就会再往北移，使北美平原没有降雨。”
