【简答题】
Unit 1-P6 Compare the two paragraphs and point out which makes a better claim and explain . 1. I am against closing the snack bars on the south side of the campus and replacing them with vending machines. I am taking courses in business at Tsinghua University and, twice a week I go there for lectures. When I come back to BFSU, though the canteens are closed, I can always get something hot at one of the snack bars-meat dumplings or noodles. I don't like machine-vended food. I think it tastes awful. So, it would be a great personal inconvenience to me if the snack bars were closed. I think they should not be closed. If they are, I will frequently have to have instant noodles for supper. 2.Closing the snack bars and replacing them with vending machines, as the logistics department proposes, will inconvenience many students who take courses or work part time off campus. The department assumes that students would prefer machines to snack bars. However, many will not. I have spoken with at least 30 students who say they'd rather skip a meal than eat machine-vended food. Machine-vended food, no matter how quickly one can get it, does not taste as good as freshly prepared dumplings and noodles. If the snack bars were closed, many students who miss a meal in the canteens will probably have to eat instant noodles or go without dinner.These students' health will be damaged. I hope the logistics department wil l reconsider its proposal.
