问题 A fire in an enclosed space burns with the aid of reflected radiation that preheats the fuel, making ignition much easier and flames spreading more quickly.

选项 A、flames spreading
B、flame spreads
C、flames are caused to spread
D、causing flames to spread
E、causing spreading of the flames

答案D

解析 由划线部分之前的much easier and及划线之后的more quickly可断定,划线部分是与前面的making ignition构成平行结构,因而排除A、B、C,它们在形式上不对称;另外cause之后一般跟动词不定式,因而选D而排除E。
