Topic: Do you agree or disagree with the following statement? The students in university should not do any part-time jobs.
Reason: Doing part-time jobs can intensify our social ability.
Exemplification: Take myself for example. When I was a fresh man，I found it really hard to get along with people around me. Then I was advised to take a job as a waiter in the restaurant during which I had chances to communicate with different customers, making them satisfied with my “smile” service. After a year, I myself can realize that I have become more outgoing and understanding.
Topic：Do you agree or disagree with the following statement? Land needs to be used to meet human need rather than to protect endangered animals.
Position：Protect endangered animals
Reason: Another important reason to protect endangered animals is that the delicate ecological balance of an area might be irreparably harmed by their extinction.
Exemplification: For example, if humans chop down forests and use the land to grow corn, they might simultaneously destroy the habitats of a kind of bird that eats locusts. The next year because the locust population can grow unchecked, locusts might destroy the entire nearby corn crop. Not only do the birds lose their homes, but humans are also harmed. The ecological balance of many natural habitats is still not well understood and humans interfere in it at their peril.
