要下雨了
有一天,蝴蝶在花草边飞翔,看见很多蚂蚁搬着许多食物往树上爬,觉得很奇怪,就问蚂蚁:“你们在干什么?”
蚂蚁笑着说:“我们全都在搬家啊。”
蝴蝶说:“你们为什么要搬家啊?”
蚂蚁说:“因为马上就要下雨了,我们怕雨会把我们的家给淹没了。”
蝴蝶说:“我只有翅膀没有手,帮不了你们,可是我能帮你们找一个安全的地方。”
蚂蚁们说:“那就先谢谢你了。”
不一会儿,就下起雨来了。蝴蝶的翅膀被雨淋湿了,飞不起来了。 但是,它还是帮蚂蚁找到了一个淋不到雨的地方。

It's Saturday morning. My parents and I are on a tour bus. There are about twenty people on the bus. Some are from America, and some are from England and Australia. They are all our friends. We are going to the Great Wall. On the bus, there are two Chinese. One is a woman, the other is a man. The woman is good at English. She is talking with us about the Great Wall. The other people are listening to her. They like the Great Wall. They want to see it very much.
