( )English for ten years,we should have enough ability to talk to foreigners. A Having studied B To study C Studied D Because having studied

解题思路： 非谓语动词
解题过程：
( )English for ten years, we should have enough ability to talk to foreigners.
A Having studied B To study 表示尚未发生。
C Studied 过去分词表示被动 D Because having studied Because后面应该跟完整句。
因为学习英语已有10年，我们应该有能力和外国人交流了。
解题思路：非谓语动词。
解题过程：按照句意可以做两个句子：
1． Because we have studied English for ten years.
2． we should have enough ability to talk to foreigners.
可以看出两句的主语都是we,这两句放在一起就是一个原因状语从句，但是有时候状语从句有省略的情况。省略的前提是：主从句的主语是同一者，且从句中含有be或者have等助动词。
因此，我们可以把第一句做省略，去掉连词，因为we和have studied的关系是主谓关系，因此我们把have studied改为现在分词，既是：having studied.
本题答案是：A Having studied
