    Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big, and they

can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).

    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the

pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly

touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses

the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.

    Why do plants do it? Most plants get what they need from the sun, the air and the ground. In some places,

the ground is very poor. It doesn't have all these important things, especially nitrogen (氮). Animal meat has a lot

of nitrogen, so some plants eat meat to get what they need. Let's hope that some of the bigger plants don't get

the same idea!

阅读材料，结合所学知识回答问题。

材料一

在启蒙时代，中国形象变为了启蒙思想家手中的一件武器。启蒙思想家普遍认为，用道德治理国家是中国的一大特征。道德与宗教、法律、礼仪、风俗融为一体，成为上至皇帝，下至小民自觉遵守的行为准则，国家因而长治久安。

——据韦克吕耶斯《论十七十八世纪法国文学中对中国现实的取舍》和许明龙《18世纪法国思想家论中国的德治》

材料二

——周宁《鸦片帝国》
