《三字经》言：“昔孟母，择邻处。”这就是“孟母三迁”的典故，那么孟母究竟搬了几次家？

In the morning , we went camping in Green Nature Park. We were happy because it was a sunny day. However, in the afternoon , when we finished our picnic(野餐), it was dark and windy. Soon ,there was a shower. Unluckily, none of us brought an umbrella. We ran about but we could find no place to hide(藏身).

Twenty minutes passed and it was still raining .There were hours to go before we reached the campsite(野营地). It was even worse that our compass showed that we went to the wrong way. We had lost our way!

We had to make a quick decision as it was raining heavily. Chris said we could set up a tent(帐篷) to hide in, so Mary and Tom helped to set up it . Chris and I tried to make a fire to keep up warm. But we couldn’t as everything was wet. We dried ourselves and waited inside the tent. At about five o’clock , it stopped raining. We decided to give up the camping trip because all of us were tired.

This camping trip may not be successful but we know each other better. And the most important thing I’ve learned from this trip is the importance of team spirit(精神).
