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 Sciencesl 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 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 investigator4 0n 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 weeks5．Test subjects were 45：men and 42 women, reportedly healthy，ranging in age from 20 t0 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 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.”
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 pronounced6．”
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．
“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 supertastin7 is not limited to bitterness．
练习：
1．In paragraph 2，John Hayes points 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 reduced salt tastes better． 2．The fourth paragraph describes briefly
√A．how to select subjects and what to do in the research． B．how to identify supertasters and nontasters．
C．why to limit the number of subjects to 87 persons． D．why to select more male subjects than female ones． 3. The article argues that supertasters
A．1ike the；taste of saltiness to block sweet tastes in food． √B．1ike snack foods as saltiness is their primary flavor． C．consume less salt because they don t like intensive tastes． D．1ike to share salty cheese with nontasters．
4. Which of the following applies to supertasters in terms of bitter taste? A．They like bitterness in foods as well as saltiness．
B．They like high．salt cheese as it has intense bitter taste． √C．They prefer high—salt cheese．which tastes less bitter．． D. They prefer high-salt cheese as it is good to health． 5. What message do the last two paragraphs carry? √A．Taste acuity is genetically determined．
B．Taste acuity is developed over time after birth． C．Taste acuity is related to one's eye and hair color． D．Taste acuity is still a mysterious subject in science．

Mt. Desert island
The coast of the State of Maine is one of the most irregular in the world. A straight line running form the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coasline.___D____(46) At that time,the whole area that is now Maine was part of a mountain range that lowered above the sea. As the glacier(冰川) descended, however, it expended enormous force on those mountains, and they sank into the sea.
As the mountains sank, ocean water charged over the lowest arts of the remaining land, forming a series of twisting inlets and lagoons(咸水湖). The highest parts of the ofrmer mountain range, nearest the shore, remained as islands. ___B____(47) Marine fossils found here were 225 feet above sea level, indicating the level of the shoreline prior to the glacier.
The 2,500-mile-long rokcy coastline of Maine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited, but many are home to thriving communities. Mt. Desert Island is one of the largest,most beautiful of the Maine coast islands. Measuring 16 miles by 12 miles. Mt. Desert was essentially formed as two distinct islands. ___F____(48)

Because the island sits on the boundary line between the temperate(温带) and sub-Arctic zones, the ialand supports the plants and animals of both zones as well as beach, inland , and aopine (高山的) plants. ___A_____(49) The establishment of Acadia National Park in 1916 means that this natural reserve will b
perpetually avaitable to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, cycling, and boating. Or they may choose to spend time at the archeological museum, learning about the Stone Age inhabitants of the island.
The best view on Mt. Desert Island is from the tip of Cadillac Mountain. ___E____(50) From the summit,you can gaze back toward the mainland or out over the Atlantic Ocean and contermplate the beauty created by a ** **.
A. It also lies in a major bird migration lane and is a resting spot for many birds. B. Mt. Desert island is one of the most famous of all of the islands left behind by the glacier.
C. The wealthy residences of Mt. Desert island selfishly keep it to themselves. D. The term comes from the activity of the ice age.
E. This mountain rises 1,532 feet, making it the highest mountain on the Atlantic seashore.
F. It is split almost in half by Sones Sond, a deep and narrow stretch of water *** long.
