     I was tired. I had been studying English for 8 years, but my spoken English was still terrible. I went to
English school every night. I read different textbooks and learned the grammar rules    1    them every
day. But during the eight years, I hadn't got any    2    at all! Being tired of school, I searched (搜索) the
Internet for "Learn English" one night. Then I found a    3    English learning system (系统). Seven days
later I started using the system to learn English. My life    4    from then on. I used the system every day.
I was    5    to find that learning English in this way was so easy and interesting. No boring grammar rules.
The articles were interesting and the stories were very funny. Then something amazing happened. One
day I    6    an American man named James in a coffee shop. Without thinking, I started to    7    him. My
English words came out automatically (无意识地). It was hard for me to believe it. I could speak English
so easily. I didn't feel any    8    or worry. James understood my ideas and feelings. We talked for two
hours without    9   . Then we exchanged e-mails and Skype IDs. We decided to talk to each other on
the Internet every week. My English has   10   greatly now. I think there are many ways of learning English
for us to use. You should stop using a way that doesn't work and find out what is helpful to you.
