There are more and more people on this planet, and this is harming the environment. It is not easy for many animal species to survive. I once watched
a video about illegal hunting. In the video, some hunters killed a tiger. It was very
cruel of them to do so. What is worse, those people also make a lot of money from this. I think it is wrong of them to sell products made from animals in danger.
It is important for us to protect nature. My friend and I have joined a local
environmental group. This weekend, we will collect money for a wildlife charity. My uncle has offered to drive us to the event. It is very kind of him to help!

B Using adjective + enough + to +verb
含义：表示主语所指的对象有足够的能力去做某件事情，意为“足够……来……”。
形容词位置：在“adjective + enough + to + verb”句型中，enough 为副词，修饰形容词，形容词一定要放在enough前面。
“not + adjective + enough + to + verb”意为“不够……来……”；“too + adjective + to + verb”意为“太……以致不能……”，两者可以表达相似的句意，但是句中要使用表达相反含义的形容词，如例句中，strong和weak是一对反义词。
