Prairie dogs数量下降，是不是应该被保护

阅读：不该保护

1. prairie dogs和cattle竞争grassland，有损农民利益；

2. prairie dogs身上带有flea，会感染plague，还能通过flea传播给人类，对健康不好；

3. prairie dogs吃草，在食物链底端，保护他们对生态系统作用很小

听力反驳：

1. cattle现在集中系统饲养，不会放养，而且prairie dog能让土壤更肥沃； 

2. 这种flea不能在人身上生存，过去50年仅有10人感染； 

3. prairie dogs很重要，他们的burrow给snakes提供habitat，而且fox等rare species以prairie dogs为food source，所以保护它们对生态系统是有用的

This week, we will discuss issues faced by secondary school administrators. I’m referring to schools for teenager students. One such issue is students who change schools. Students change schools for many different reasons, the most common being a family move. On the discussion board, I want you to exchange ideas about what schools can do to make the transition to a new school easier for teenagers.

I think schools should assign new students a fellow student who can help them adjust. The "student buddy" can do things like making sure the new student can find the cafeteria or the right classrooms. For new students, it's a lot easier to ask a fellow student a question rather than ask a teacher or the principal.

I would require new students to sign up for some school club or activity that meets outside of class. That way, new students would have an easy way to meet other students in a friendly environment. It would give them a group to immediately identify with.
