Just about every kid in the US has heard this from a parent or grandparentOften，its accompanied by an appeal：“Just think about those starving orphans(孤儿) in Africa! ” . Sure，we should be grateful for every bite of foodUnfortunately, many people in the US take too many bitesInstead of staying “clean the plate”，perhaps we should save some food for tomorrow 2. According to news reports，US restaurants are partly to blame for the growing bellies (肚子)A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government；according to a USA Today storyAmericans traditionally associate quantity with value and most restaurants tyro give them thatThey prefer to have customers complain about too much food rather than too little3. Barbara Rolls，a nutrition(营养)professor at Pennsylvania State University, told USA today that restaurant portion sizes began to grow in the 1970s，the same time that the American waistline(腰围)began to expand4. Health experts have tried to get many restaurants to serve smaller portions. Now，apparently, some customers are calling for this tooThe restaurant industry trade magazine QSR reported last month that 57 percent of more than 4000 people surveyed believed restaurants served portions that were too large；23 percent had no opinion；20 percent disagreedBut a closer look at the survey indicates that many Americans who cant afford fine dining still prefer large portionsSeventy percent of those earn at least $150，000 per year prefer smaller portions；but only 45 percent of those earning less than $25，000 want smaller5. Its not that working class Americans dont want to eat healthyIts just that，after long hours at lowpaying jobs，getting less on their plate hardly seems like a good dealThey live from paycheck(薪金支票)to paycheck，happy to save a little money for next years Christmas presents习题：1.

Lowsalt foods may be harder for some people to like than others，according to a study by a Penn State College of Agricultural Sciences food scientistThe research indicates that genetic factors influence some of the difference in the levels of salt we like to eat2. Those conclusions are important because recent，wellpublicized 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，assistant professor of food science，who was lead investigator on the study3. Diets high in salt Can increase the risk of high blood pressure and strokeThat 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 eatThis study increases understanding of salt preference and consumption4. The research involved 87 carefully screened participants who sampled salty foods such as soup and chips，on multiple occasions，spread out over weeksTest subjects were 45：men and 42 women, reportedly healthy，ranging in age from 20 to 40 yearsThe sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettesThey rated the intensity of taste on a commonly used scientific scale，ranging from barely detectable to strongest sensation of any kind 5. “Most of us like the taste of saltHowever，some individuals eat more salt，both because they like the taste of saltiness more，and also because it is needed to block other unpleasant tastes in food,” said Hayes. “Supertasters, people who experience tastes more intensely, 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.”6. 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 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”7. 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 chemicalsAs 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 color8. “Some people，called supertasters，describe bitter compounds as being extremely bitter，while others，called nontasters，find these same bitter compounds to be tasteless or only weakly bitter”he said“Response to bitter compounds is one of many ways to identify biological differences in food preference because supertastin is not limited to bitterness 1.In paragraph 2，John Hayes points out that _. （C）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 reluctantlyD.food with reduced salt tastes better.36 John Hayes pointed out that _.
