单选题The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are inclined to catch certain illnesses because of the food that is characteristic(典型) in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates (硝酸盐) and nitrites, commonly used to preserve color in meats, and other food additives(添加剂) , caused cancer. Yet, these carcinogenic (致癌的) additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin(青霉素) to beef and poultry and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration has tried repeatedly to control these procedures, the practices continue.

单选题{{B}}Task 5{{/B}}The following is a letter of complaint．After reading it，you are required to complete the statements that follow the questions(No．56 to No．60)． Dear Sirs， The shipment of 850 copies of exam paper we ordered for delivery on 20 Jan．2009 did not arrive until the morning of 22 Jan．(Only 2 hours before the exam．)It should have been sent to us 2 days before．Besides，too many typing errors were found here and there in the paper. The job is by no means satisfactory to us： 1) The late delivery is inexcusable，since we have made it very clear when we wanted the paper in hand．Our teaching staff were found in a tight corner--the exam was to be held on time but we had not got the paper on time． 2) The typing suggests that the job was done at the last minute and so carelessly without enough time to check．We have here enclosed a copy with all the errors underlined．Since your typing and printing job and your delayed delivery don’t meet our professional expectation，we are writing to inform you that we have to lodge a claim by suggesting that you make us an allowance of 20%on the invoice cost．Please call Miss Spring at extension 2123,if this request presents any problem to you．We look forward to your cooperation on this matter． Yours sincerely， John Brown Headmaster of California High School
