问题补充：

as many local people as possible when you are abroad and you find it easier to overcome the culture difference.

A. To know

B. Knowing

C. Known

D. Know

答案：

A. To know

B. Knowing

C. Known

(答案→)D. Know

解析：句意:当你在国外的时候，你要尽可能地了解当地人，你就会发现克服文化的差异是比较容易的。因为and后是一个句子，所以它的前面也必须是一个句子，when引导的是从句，所以缺少主句，因此必须用谓语动词，故选D。
