【简答题】
How did it make you feel when you learned that KFC’S Beijing restaurants pulled three more items from their menus last week? There were fears that the items may have contained the cancer-causing coloring Sudan I.Do you have any desire to take the food provider to court because it feeds you something dangerous? After all,the law supposedly gives people the right to fight for their rights.But some experts have said it might not be so wise to take the company directly to court. Qiu Baochang,a lawyer in Beijing,suggested that consumers not take the company directly to court.“In addition to the high costs,consumers’complaints are unlikely to win unless they can prove they have had the banned dye at KFC,”—Qiu explained. One problem for those wanting to take action against the fast food chain is that few customers ask for or keep receipts(收据).And,this must be the first step. If they can prove that their health has been damaged by KFC,they can cue(控告)the company.But that would be almost impossible to do so because the Sudan I damage is a long-term effect and is not immediately apparent. A KFC spokesperson said on Monday that the company was confdent of being able to handle customers’complaints,“We will obey legal procedure if We raceive any complaints.” 小题1:Why did KFC’s Beijing restaurants pull three more items from their menus? A.Because the company was afraid to handle customers’complaints. B.Because coloring Sudan I may have been contained in those items. C.Because the KFC’s restaurants were accused ofselling poisonous food to the customers. D.Because these items were no longer popular with the customers. 小题2:The reason why experts suggested not taking the company directly to court is that . A.the costs will be high B.consumers can’t prove food contained Sudan I C.consumers can’t prove the food at KFC damaged their health D.all of the above 小题3:This passage most probably appears in . A.a notice. B.a book on cooking. C.a story book. D.a newspaper. 小题4:What is the general ieda of the passage? A.KFC’s Beijing restaurants pulled three items from their menus last week. B.How the consumers dealt with the KFC problem. C.How KFC handled the customers’s complaints. D.Consumers never forget to ask for or keep receipts.
