如何让老外每天帮你免费改英语作文？

来自美国的3位网友就在12分钟、10分钟和7分钟前给出了三个修改。修改意见如下：

"I have lived in New York for 17 years."

"I have been living in New York for 17 years."

Either one.

和

Is this phrase correct?

" i have been lived in New York for 17 years "

If you still live in NY you should say:

"I have been living in New York for 17 years"

还有

Is this phrase correct?

" i have been lived in New York for 17 years "

It should be

"I have lived in New York for 17 years."

也就是说发出作文仅仅8分钟内，就获得3个来自不同英语母语人士的修改！仅仅8分钟之内啊！而且每个回答从不同侧面给予分析，非常有帮助。

为什么母语人士这么积极参与作文修改呢？不仅是由于他们有雷锋精神，而是因为修改作文后可以获得“社区活动点数”（Community Activities point）的奖励以及点赞。这类似可汗学员的积分和知乎的点赞功能。

这个小作文功能可以修改任何语言的作文，也就是说可以帮你学习其他外语。我就尝试帮外国友人改中文作文呢。
