系统解析：M: Stella, how's the new student in your class doing?
W: The kid from Brazil? He's having a rough time communicating since he doesn't speak much English. However, the other kids seem to include him pretty well.
M: As teachers, we should be used to new kids who don't speak much English, since we've had so many new immigrant families move into our school district.
W: Don't I know it! This year I have had a Cambodian, an Ethiopian, a Chinese and the kid from Brazil in my class. I spend a lot of time with them after class, so that they can catch up.
M: It must have been hard for you, since you have to give them special attention in order to help them.
W: It has been. However, it's really rewarding to see them progress and make friends.
