请大侠帮忙用英文翻译这2句话～～

jcyzyf and alexdds的对招聘信息的翻译不对，因为这只是招聘广告，还不到面试阶段，更谈不上给offer。至于bamlook老兄用"invit application"就更不靠谱了。

（本人来美国十年了，是美国永久居民，英文应该还可以，望指正）如果我来翻译的话是这样：

I've learned from your company's web site that you have job openings. （这样说比较正式一些，在这种情况下，一般不说“前几天”，这是美语习惯，我也不知道为什么，可能是因为找工作是现在时吧）。
I have some knowledge and experience on Beijing's xxx market，或者on selling/marketing xxx. xxx是指你的产品，中英文中都没有“销售市场”这一说吧。实际上，美语中在这个上下文也不习惯说“比较熟悉”，而是用具体年数来做说明，比如，I have 7-year experience on marketing in IT industry, 我在IT业有七年市场营销经验。

因为你说要地道英文，我就照实说了。其实在国内没关系，我就不信招聘者的英文比你强多少，所以不要有心理负担，能让人看懂就可以了。祝找工作顺利。

A few days ago, I gained the recruiting information you advertised on the zhaopin.com.

I am very familiar with the sales market in Beijing.

我觉得英文求职信里，你第一句话这样更好：
I am writing in response to your advertisement for recruiting
或
I am writing to apply for the position of…you advertised in

I saw the information about your company on Zhilian Interview on Internet several days ago.

I'm very familiar with the market on whole Beijing.

I have seen the invit applications for the job at ZhiLianZhaoPin's web pages during last days.

I'm very familiar with BeiJing's Market.

I found the offer from your company by Zhi Lian.
I am familiar with sell market of around Beijing.
