温度影响口味

Does an ice cold drink actually taste better than the same beverage at room temperature?

Depends on what its taste is: a new study finds that the intensity of some flavors varies with temperature. The work is in the journal Chemosensory Perception. Researchers took solutions that tasted bitter, sour, sweet, or astringent ― a flavor found in legumes and raw produce that creates a dry,puckering feel in the mouth. They either chilled the solutions to 5 degrees Celsius, the recommended temperature for keeping food cool…or heated the solutions to 35 degrees Celsius, a couple degrees below human body temperature. Volunteers then rated the tastes. Both sour and astringent solutions tasted stronger at warm temperatures, and the intensity lasted longer than it did with chilled drinks. Bitter flavors came through best when chilled. And temperature had no effect on perception of sweetness. For most people, temperature can enhance flavors. But for some, dubbed thermal tasters, temperature alone can be a flavor. Heating or cooling parts of the tongue creates the sensation of taste without food― a finding that's hard to swallow.

英语六级考试口语部分，大家在考试的时候一定要学会倾听，锻炼自己的听力能力。很多同学会走进一个只练口语表达能力，不用提高听力能力的误区，在口语表达与交流中，学会去听是非常关键的。因为只有听清楚了，才能知道别人说的具体内容以及自己如何去准确表达。
