以下是2b课文的原文,通常以一封邮件的形式呈现。

Subject: My favorite TV shows

Hi Linlin,

Thanks for your email. You asked about my favorite TV shows, so I'd like to tell you about them.

My favorite TV show is Tiger Watch. It's a talent show. I love it because I can learn a lot about animals from it. It's also very exciting. The host is very funny, and I always laugh a lot when I watch it.

My parents' favorite show is World News. They watch it every day because they want to know what's happening around the world. I think it's boring, but it's very important.

My sister loves sitcoms. She thinks they are very relaxing. My brother can't stand sports shows. He says they are too noisy. As for me, I don't mind sports shows. Sometimes they are very exciting.

What about you? What's your favorite kind of TV show? Please write and tell me.

Best wishes, Mei
