A.so stalking them over the treeless landscape, getting close enough to kill it
B.so to stalk them over the treeless landscape and get close enough to kill one
C.so in order to stalk them over the treeless landscape and get close enough to kill one
D.and so in order to stalk it over the treeless landscape, getting close enough to kill it E.and so stalking them over the treeless landscape and getting close enough in order to kill it
答案是B，我没有问题。 E中的it不对，和in order to累赘我也没问题。 但是Prep笔记中的解释：“and后半句没有主句”我不理解。 stalking and getting required skill. 不就是主句吗？ 另外，我突然发现，为什么要用required呢？全文时态不都是一般现在时？
