At week 9, we begin to prepare our final assignment. First, we need a plan for what each team member needs to do. For example, someone is responsible for finding information, then summing up the main meaning of the article, and someone is responsible for taking our interview. We have listed several issues regarding species extinction to ask people, such as, what causes extinction and how do you think an extinct species will affect humans. Most people think that the environment is the main factor in the extinction of animals, and they also believe that the extinction of animals will have a great impact on human. I think these two questions are crucial because the ecology is in a state of balance, but if there are a large number of species extinct, the ecological balance will be destroyed and the human living environment will also be affected. In the process of final assignment, I think the hardest part is writing script, because it takes seven to ten minutes, so we need to read a lot of information to write our scripts.
