Peter: Molly, look at this. The newspaper says we should sort trash.
Molly: That would be great! I always hate it when people mixing all the trash together.
Peter: {A; B; C; D; E} Many communities have already done that.
Molly: Yeah. The benefits of sorting out trash are obvious.
Peter: For instance？
Molly: If trash is sorted, it can be transferred to factories instead of the disposal plant.
Peter: That makes sense. {A; B; C; D; E}
Molly: With trash separated, pollution caused by incineration can be avoided.
Peter: It is high time for us to sort out the trash. Trash is trash only when everything is mixed together. {A; B; C; D; E} they can be useful again.
Molly: {A; B; C; D; E} Things like paper, glass, and plastics can all be recycled. They can be reused.
Peter: Sorting is good. {A; B; C; D; E} If people have no idea how to sort their trash, they will still put all waste in the same bag.
Molly: You are right. People should be informed about how to do that in the first place. Moreover, sorting trash should be made easy for us. Otherwise, few people would bother to do it.
Peter: I hope everything goes smoothly!
Molly: I believe it will.

听力原文： Welcome to Physiology 100. I'm Doctor Ann Roberts. I assume everyone here is a sophomore, since this is the Nursing Department second-year physiology course. If you are first-year nursing students, please see me after class about transferring into introductory course. OK, I'd like to begin my first lecture by introducing two important terms, vitalism versus mechanism. How many of you have heard of these terms？ Oh, I see sorae of you have. Well, vitalism and mechanism are two completely opposite approaches to human physiology. According to the vitalist, the laws of physics and chemistry alone can not explain the processes of life. To the vitalist, there is a so-called vital force, and this vital force is totally separate from that of energy. As you may have guessed, vitalism is a kind of philosophical approach. Mechanism, on the other hand, is the view that all life phenomena, no matter how complex, can be explained according to chemical and physical laws. Since we can support mechanism through scientific experimentation, the modern scientist tends to be a mechanist. But vitalism is not totally dismissed, especially in fields such as brain physiology, where terms such as human consciousness haven't been defined yet in physic-chemical terms. I recently read an interesting article that dealt with this very question. Is the mind separate from brain, or is the mind only the chemical and physiological workings of the brain.'？ I'd like to continue with this next time, so that we can speak in more detail. I have some copies of that article. And I want you to take it with you and read it for next week.
For whom is the lecture intended？
A．Freshman.
B．Sophomore.
C．Junior.
D．Senior.
