第二篇 Some People Do Not Taste Salt Like Others
　　Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.
　　Those conclusions are important because recent, well-publicized (大力宣传的) efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, lead investigator on the study.
　　Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.
　　The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind.
　　"Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and because it is needed to block other unpleasant tastes in food," said Hayes. "Supertasters, people who experience tastes more tensely, consume more salt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more. "
　　However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted. "For example, cheese is a wonderful blend of dairy flavors from fermented (发酵的), milk, but also bitter tastes from ripening that are blocked by salt," he said. "A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced.
　　Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result, Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color.
　　36 John Hayes pointed out that __________.
　　A it is good to health to eat food without salt
　　B many people reject low-salt food completely
　　C many people accept low-salt tasteless food reluctantly
　　D. food with less salt tastes better.
　　37 The fourth paragraph briefly describes______?
　　A the purpose of the study.
　　B the research methodology.
　　Cthe analysis of the research resuls.
　　D the conclusion of the study.
　　38 The article argues that supertasters
　　A like the taste of saltiness to block sweet tastes in food。
　　B like snack foods as saltiness is their primary flavor。
　　C consume less salt because they don’t like intensive tastes。
　　D like to share salty cheese with nonstarters。
　　39 in paragraph 6，the word “pronounced”is closest in meaning to ________
　　A weary B weak C strong D strange
　　40 The last two paragraphs illustrate that taste acuity is
　　A genetically determined．
　　B developed over time after birth。
　　C related to one’s eye and hair color．
　　D still unknown to scientists．
