Irradiating Food

Irradiating fruits, vegetables, pork and chicken to kill insects and bacteria has been approved by the Food and Drug Administration over the past decade. Irradiation of other meats, such as beef and lamb, is being reviewed. Federal approval does not require that industry adopt the process, and few food processors presently offer irradiated products.

Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some people argue that more severe government inspection, higher food-safety standard and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the equipment necessary for a process that very few shoppers are in favor of.

All supermarkets that sell irradiated food must label the food either directly on the packaging, or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients.

Presently, the FDA allows food to be treated with three types of radiation -- gamma rays (伽马射线), high-energy electrons, and X rays -- and sets limits on doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different doses of radiation.

Killing insects and bacteria present in foods by irradiating is completely approved by the US government.

A．Right

B．Wrong

C．Not mentioned

Montaigne's hold on his readers arises from many causes. There is his frank and curious se

lf-delineation. That interests, because it is the revelation of a very peculiar nature. Then there is the positive value of separate thoughts imbedded in his strange whimsicality and humor. Lastly, there is the perennial charm of style, which is never a separate quality, but rather the amalgam and issue of all the mental and moral qualities in a man's possession, and which bears the same relation to these that light bears to the mingled elements that make up the orb of the sun. And style, after all, rather than thought, is the immortal thing in literature. In literature, the charm of style. is indefinable, yet all-subduing, just as fine manners are in social life. In reality, it is not of so much consequence what you say, as how you say it. Memorable sentences are memorable on account of some irradiating word. "But Shadwell never deviates into sense, for instance." Young Roscius, in his provincial barn, will repeat you the great soliloquy of Hamlet, and although every word may be given with tolerable correctness, you find it just as commonplace as himself. The great actor speaks it, and you "read Shakespeare as by a flash of lightning". And it is in Montaigne's style, in the strange freaks and turnings of his thought, his constant surprises, his curious alternations of humor and melancholy, his careless, familiar form. of address, and the grace with which everything is done, that his charm lies, and which makes the hundredth perusal of him as pleasant as the first.

Literature lives because of the author's ______.

A．ideas

B．humor

C．surprises

D．style
