The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a signifi cant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since . (A) many of the proponents of irradiation are food distributors who gain from foods’ having a longer shelf life (B) it is clear that killing bacteria that may be present on food is not the only effect that irradiation has (C) cooking is usually the fi nal step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods (D) certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is (E) for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded作者: 澤澤 时间: 2010-3-30 23:15
104.Although the discount stores in Goreville’s central shopping district are expected to close within fi ve years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long.

(C) At present, the central shopping district has as many stores operating in it as it ever had. (D) Over the course of the next fi ve years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades.
