My classmate Li Qiang and I go to school by bys every day. Last Wednessday, we saw a young man in black stealing a wallet from a woman. We stood up at once and caught him by the arm.

The thief was much taller and stronger than us, but with the help of the driver and the passengers, we caught him at last and took him to the police station.

我和同学力强每天乘公共汽车上学。上星期三我们看到一个穿黑衣服的年轻人在偷一位妇女的钱包。我们立刻站起身来抓住他的胳膊。

小偷比我们又高又壮，可是在司机和乘客的帮助下，我们还是抓住了他，并把他送到派出所。
