帮忙找语病，谢了

I have (learned) English (for)nearly (你想说一个半月是a month and a half）你想说半个月是a half month。
是much knowledge，不可数。
speak English （easily）
我只能改出这么多。

错误太多了，建议重新理一下。

1. learnt,要用过去分词。
2. 一个半月用 a month and a half.
3. In these time.
4. never known, 用过去分词。
5. easily, 用副词修饰speak。
6. I mean what I said, 我之前说过的，用said。

I have learnt English for nearly a month and a half now. In these time, I have learnt much knowledge than you never known. I feel good today, and wish someday I can speak English leisurely.

1. I have been learning English for nearly half a month now.
2. I've learnt more knowledge than you ever know.
开始晕了 你想表达什么
3. I wish someday I can speak English frequently.
4. I'll always learning English with no regret.
I mean what I say倒是没错
最后的日期 要 05 December 2009
