airport or bus terminus this holiday, will you try to analyze what it is about queuing that makes you angry? Or will you just get angry with the nearest official? Professor Richard Larson, an electrical engineer at the Massachusetts Institute of Technology, hates queuing but rather than tear his hair out, he decided to study the cites an experiment at Houston airport where passengers had to walk for one minute from the plane to the baggage reclaim and then wait a further seven minutes to collect their were frequent, especially from those who had spent seven minutes watching passengers with just hand baggage get out airport authorities decided to lengthen the walk from the aircraft, so that instead of a oneminute fast walk, the passengers spent six minutes walking 47 The extra walk extended the delay by five minutes for those carrying only hand baggage, but passenger plaints dropped almost to reason? Larson suggests that it all has to do with what he calls “social justice”.If people see others taking a short cut, they will find the wait Another aspect Larson studied was the observation that people get more fed up if they are not told what is going But even knowing how long we have to wait isn39。如何獲取積分?2011年職稱英語理工類A級考試試題Some People Do Not Taste Salt Like Others(A級)(無換題現(xiàn)象)Lowsalt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences1 food research indicates that genetic factors influence some of the difference in the levels of salt we like to conclusions are important because recent, wellpublicized efforts to reduce the salt content in food2 have left many people struggling to accept fare that simply does not taste as good to them as it does to others3, pointed out John Hayes, assistant professor of food science, who was lead investigator? on the high in salt can increase the risk of high blood pressure and is why public health experts and food panies are Working together on ways to help consumers lower salt intake through foods that are enjoyable to study increases understanding of salt preference and research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 sample was posed of individuals who were not actively modifying their dietary intake and did not smoke rated the intensity of taste on a monly used scientific scale, ranging from barely detectable to strongest sensation of any kind.“Most of us like the taste of , 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 mtensely, consume more salt than nontasters 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, milk, but also bitter tastes from ripening that are blocked by salt,” he said.“A supertaster finds lowsalt cheese unpleasant because the bitterness is too 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 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.”Some people, called supertasters, describe bitter pounds as being extremely bitter, while others, called nontasters, find these same bitter pounds to be tasteless or only weary bitter,“ he said.”Response to bitter pounds is one of many ways to identify biological differences in food preference because supertasting7 is not limited to bitterness.(476) paragraph 2, John Hayes points out that在第二段中。 to limit the number of subjects to 87 。 of the following applies to supertasters in terms of bitter taste? 對于口味超重的人,下列哪項比較適用于苦味? like bitterness in foods as well as 。 acuity is related to one39。 acuity is genetically ,味覺的敏感度由基因決定。t like intensive ,因為它們不喜歡重口味。 to select subjects and what to do in the 。s no doubt that we39。s roundhouse?
