1What _d__to her?
A happen B was happened C happening D happened
不是应说What had happened to her吗?为什么这么用?
2She swam to the shore_A__the night in the water
A having spent B having spending C when spending D had spent
为什么?不明白
3 We climbed_up_ to__the shop of the mountain
为什么up 后还要加to?

第一个应该选D,因为这里没有明显的语境或时间状语表示过去完成时,所以最佳答案是D.
第二个A,是现在分词短语的完成时做状语,表时间,相当于when she had spend
第三个加to是因为up本身后面不能够直接加宾语,必须用to
现在知道了吗?

A B

可以说;

we climbed to the shop

or

we climbed up to the shop

不过你可以说:

we climbed up the shop:

但是意思跟; we climbed up to the shop 是不一样的, 想想吧, 呵呵
