问题 Street sellers, particularly in developing countries, supply large amounts of food to people【C1】______low incomes. This sector also employs some 6%-25% of the work force, mainly women, in developing countries, and provides markets for agricultural and other【C2】______. In many countries, however, the authorities are not willing to【C3】______it as a formal sector of the food supply system. They may ignore it in food control programs or even try to put an end to it.
There are two possible【C4】______: pathogenic micro-organisms and hazardous chemicals. As far as micro-organisms are concerned, there is apparently no convincing evidence that street foods are more involved in the transformation of infection than foods obtained in, e.g. hotels. Studies in Egypt and elsewhere have found street foods to compare not【C5】______with hotel foods in respect of contamination with micro-organisms—some street foods were found to be contaminated with pathogens, but so were foods from four- and five-star hotels in the same area.
Hazardous【C6】______have been found in street foods, and food exposed for sale on roadsides may become contaminated by lead from vehicle exhausts.
Health dangers may【C7】______with: purchase of raw material of poor quality; improper storage, processing, and cooking; limited piped drinking-water; lack of【C8】______; unsatisfactory waste-disposal facilities; and personal cleanliness. The authorities should take into account the potentials of different categories of food for transmitting diseases. Dry foodstuff, dried grains, and【C9】______foods are less likely to transmit diseases than gravies, cooked rice, and low-acid milk, eggs, and meat products. Similarly foods which are thoroughly cooked and eaten at once are safer than【C10】______food kept at high temperatures for several hours.
A. on B. produce C. sugared
D. precooked E. with F. chemicals
G. product H. ice I. consider
J. unfavorably K. recognize L. arise
M. refrigeration N. contaminants O. favorably
【C3】
选项
答案K
解析 recognize，词义辨析题。根据词性，此处应当填入动词。此处表示政府不愿将其视为正式的食物供给体系的一部分。根据语义可选范围为“consider，recognize”。consider sb．／sth．as sth．“认为；视某人／某事物为”；recognize sb．／sth．(as sth．)“承认某人／某事物有效或属实；认可”。此处指政府拒绝承认街边摊贩为食物供应体系之一，consider强调“(主观)认为，视作”；而recognize更侧重“(官方)承认，认可”。故最佳答案为recognize。
