Eating too much of it can【C1】______to high blood pressure, a major risk for most people【C2】______they age because it can lead to heart disease and other health problems. But cutting sodium【C3】______the diet is difficult, mainly because people often don’t know it’s there. More than three-quarters of the sodium people【C4】______comes from processed and restaurant foods. And much of the sodium we eat is in foods that don’t【C5】______taste salty, like packaged bread and chicken dishes. Salt is the latest【C6】______in the battle to get Americans to eat a healthier diet.【C7】______efforts have focused on cutting down on sugar, to【C8】______obesity, and reducing fat, for a healthier heart.

An advisory committee working on new US Dietary Guidelines.【C11】______to be released later this year by the federal government, recently recommended that all adults restrict their【C12】______of sodium to no more than 1 500 milligrams a day, 【C13】______to about two-thirds of a teaspoon of table salt, down from a current limit of 2 300 mgs for some people.

Nutritionists【C15】______eating whole grain instead of bread—a single slice of packaged bread can【C16】______150 mgs to 200 mgs or more of sodium. Cut back【C17】______, so your palate (味觉 ) adjusts to a less salty taste. When you do buy artifactitious (人工制品的) foods, look for【C18】______with less than 300 mgs of sodium per serving, or no more than one milligram of sodium per calorie of food, advised the Harvard School of Public Health, 【C19】______has on its website 25 sodium-reduction【C20】______developed with the Culinary Institute of America.

选项 A、gradually
B、slowly
C、progressively
D、increasingly
答案A
解析 副词辨析题。结合句意，减少盐的摄入，味蕾就会逐步适应较淡的口味。根据句中的less说明一种变化的过程，因此答案为A)gradually“逐渐地，慢慢地”。B)slowly“逐渐减慢地”，一般用于形容速度；C)progressively“逐步提高地”，与文意相反；D)increasingly“逐渐增加地”，与less相反。
