问题补充：

a little money, Jane was able to buy her mother a lovely new watch.

A. To save

B. Saving

C. Having Saved

D. Saved

答案：

A. To save

B. Saving

(答案→)C. Having Saved

D. Saved

解析：To save表示目的；Having done表示它的动作发生在谓语动词之前；根据was able to能够买并且也已经买了可知这里不是表目的，简给她的母亲买一块新表的愿望已经实现了，根据句意应该先攒够钱然后又买的，故选A。
