生动

I wanted to go to the park, but it started raining heavily. 我本想去公园，但却下起了大雨。The food looked delicious; nevertheless, it tasted rather bland.食物看起来很美味，但尝起来却相当平淡。

At first, the problem seemed difficult, but as we discussed it more, we found an easy solution.一开始，这个问题看起来很难，但随着我们讨论得更多，我们找到了一个简单的解决方案。

The lesson I like most is history, because the historical stories are interesting.
