Last weekend, whether to go climbing or to see a film confused us. Some preferred seeing a film to going climbing while I would rather go climbing, for hard conditions could build up our characters. Finally, they were satisfied with my proposal and therefore we went climbing.

　　Equipped with some necessities, we went to the mountain that was rich in mushrooms, which were mainly exported to foreign countries. Upon putting up the tent at the foot of the mountain, we struggled to climb. Focusing on finding our way, we came across what was called a poisonous snake, leading to our having to stop. We had to choose another way to keep us free from its attack. But much to our regret, we didn't see any mushroom on this way. To make matters worse, we lost our way. Thanks to a local worker, we rid ourselves of the trouble.

　　Later, our teacher made a comment about our performance, which made us proud of ourselves.

　　上个周末，是去爬山还是去看电影让我们很为难。一些人选择去看电影而不选择爬山，而我则宁愿爬山，因为艰苦的条件能磨炼人的性格。最后，他们对我的提议感到满意，因此我们就去爬山了。

　　准备好一些必需品后，我们就去盛产蘑菇的那座山了，那里的蘑菇主要出口到国外。在山脚下一搭好帐篷，我们便奋力攀登了。在集中精力找路的时候，我们碰到了一条所谓的毒蛇，致使我们不得不停下来。为了免受它的攻击，我们选择了另一条路。可是让我们感到非常遗憾的是，在这条路上我们没有看到任何蘑菇。更糟糕的是我们迷路了。多亏当地的一个工人，我们才摆脱了困境。

　　后来，老师对我们的表现发表了评论，让我们感到很自豪。
