问题 Food is irradiated (用辐射处理) to provide the same benefits as when
it is processed by heat, refrigeration, freezing or treated with chemicals to
destroy insects, fungi or bacterium that cause food to spoil or cause human (1) _ ____
disease and to make possible to keep food longer and in better condition in (2)______
warehouses and homes. Irradiated foods are wholesome and nutritional. All (3)______
known methods of food processing and even storing food at room tempera
ture for a few hours after harvesting can lower the content of some nutrients,
such as vitamins. At low doses of radiation, nutrient losses are either not
measurable or, if they can be measured, are not significant.
At the higher doses used to extend shelf life or control harmful bacteria,
nutritional losses are less than or about the same with cooking and freezing. (4)______
The irradiation process involves passing food through an irra
diation field; however, the food itself never contacts with a radioactive (5)______
matter. Also the ionizing radiation used by irradiators is not strong enough (6)______
to disintegrate the nucleus of even one atom of a food molecule.
Irradiation does produce chemical changes in foods. They have been
scrutinized by scientists in making safe assessments of irradiated foods. (7)______
Any kind of treatments causes chemical changes in food. For instance, heat (8)______
treatment, or cooking, produces chemicals that could be called "thermolytic
products." Scientists find the changes in food created by irradiation minor to
that created by cooking. The products created by cooking are so significant (9)______
that consumers can smell and taste them, whereas only a chemist with ex
tremely sensible lab equipment may be able to detect radio lytic products. (10)______ [br] (2)

选项

答案 make∧— it

解析此题的关键在于看出make后面不可能直接跟形容词，应该首先跟一个名词词组或代词作宾语，然后跟形容词作宾语补足语。此处to keep food longer and in better condition in warehouses and homes是make的实义宾语，所以在make之后应该有一个形式宾语it。结构的完整性也是八级改错的一个考点。
