"I'm very glad to make friends with you

Hello everybody ,My name is Zhangzhenyu.I'm from Mianyang City ,Sichuan Province,China.I want to make friends with you。Also,I want to make friends with foreign people more。And I can prove my English skills.Can you help me ? "

"I'm very glad to make friends with you" - 这样的说法意思是说你已经和我交朋友了所以你很开心。我想你想要说的是 '很高兴如果能够和你做个朋友'对吗？应该是：'I would be glad if we could become friends'. 

"I want to make friends with foreign people more." － 以我能够理解的是你比较喜欢和外国人交朋友。这样的说法比较恰当：'I would prefer to make friends with foreigners'

"And I can prove my English skills"－ 这句子意思中文翻译是 '我可以证明我的英文水准'.如果你想要说的是'你可以清楚理解我的英文水在那里' ：'I would prefer to make friends with foreigners because（因为）they could 

guage my level of proficiency in english language。' 因为这句子开头是'And'，我就想说那两个句子应该是连在一起的吧。
