A.not being finished B.not having finished C.had not been finished D.was not finished  

Answer 1

应该是：
1. A。pointed （意思是它的耳朵竖起来）
2. B。not having finished （意思是 我们的工作还没有完成，是一个片语，也可以说成：but not having finished our work, ....）
希望帮到你。

Answer 2

这两题考点是非谓语动词。
1.选B。ears与point是种主谓关系，用主动。
2. 选A。our work not being 叫做 独立主格结构，这里做状语，表示原因，相当于 because our work was not finished
B 用的是主动式，显然不对。
D似乎对，但是两个并列句中间不能这么用逗号隔开。如果在we 前面加一个so就对了。　
C用过去完成时表过去的过去，此处没有此意。
