1.介绍当前背景、现象、形势+说出自己的观点

例1：

As the competition for college education becomes severe, more and more parents begin to pay special attention to their children’s early education. As a result, kindergarten children are forced to learn foreign languages, and primary school children gasp under the burden of heavy homework and endless classes. In my opinion, playing for young children is more important because they can learn about society and nature through playing and they can build up a strong body.

例2：

Zoos have come a long way from their grim beginnings. Once full of tiny cement-block cages lined with steel bars, the larger zoos now boast simulated jungles, veldts, steppes, and rain forests, all in an attempt to replicate the animals’ natural habitat. The attempt is admirable, but it’s not enough. No amount of replication, no matter how convincing, is enough to make up for denying these creatures their freedom.

2.介绍双方观点+说出自己的观点

例1：

Young people tend to think that real life is as dramatic and fascinating as it is in the novels and movies, while more experienced adults disregard this opinion. Adults think this kind of na?ve daydream will only be destroyed by later experiences and every one should learn to get used to tedious everyday life. In fact, I believe that realism is necessary, but idealism is more important to increase the quality of our life.
