Question

If you want to learn skating, it is important to learn _______ yourself.

1. A.
   to keep to balance
2. B.
   to keep balancing
3. C.
   to keep skating
4. D.
   to keep to skate

Answer 1

B
本题除了考查balance的动词用法之外，还考查了对句意的理解能力。因为从选项看，在结构方面，B、C两项均是正确的（keep后面须接动名词）。句意为“如果你想学会滑冰，学会保持平衡是很重要的”。而C项的意思是“学会不断地滑”，显然不合句意。
