To find out how hot the filling can be, a team in China did a test. They found that the average temperature of the filling can reach 64℃ when the pies are taken out of the oven. According to China Science Communication, they suggest the temperature for food is around 10℃ to 40℃, and food that is over 60℃ can hurt our throat. The reason for this is that the filling is thick and not exposed (暴露) to air. Once heated, it keeps heat for a long time. The test shows that after a pie from KFC has been out of the oven for 10 minutes, the temperature inside still reaches 45.1℃. The temperature difference can be explained using a physics concept (概念) called specific heat capacity (比热容). This tells us how much heat is needed to change the temperature of 1 gram of something by 1℃. Something with a low specific heat capacity is like a small cup; it doesn’t hold much heat and cools down fast. Things with a high specific heat capacity take longer to cool down. Usually, liquids (液体) hold heat longer than solids (固体). As a pie’s filling has more water than its crust, it takes more time for the filling to fully cool down. 1．What is the problem with pies from KFC or McDonald’s A．The fillings taste like lava. B．They cool down too quickly. C．The hot fillings can burn eaters. D．The crusts become too hard when cooled. 2．What is the safe temperature range for food A．From -10℃ to 40℃. B．From 10℃ to 40℃. C．From 25℃ to 60℃. D．From 40℃ to 64℃. 3．What is the main reason why the pie filling stays hot longer than the crust A．The pie filling is thicker than the crust. B．The filling is made of special food. C．The filling gets hot faster when cooked. D．The filling has a higher specific heat capacity. 4．According to the last paragraph, which of the following cools down the slowest at the same temperature A．Bowl. B．Cake. C．Milk. D．Glass. 5．What is the passage mainly about A．Why pie fillings cool down slowly. B．What specific heat capacity is. C．What helps cool down a pie quickly. D．How KFC pies will be improved. Do you like Lanzhou beef noodles They come from Lanzhou, Gansu. It dates back to the Tang Dynasty (618–907). Over 100 years ago, a cook called Ma Baozi made the dish well-known on the streets of Lanzhou. And since the 1980s, Lanzhou noodles have become known around the world. Now, Lanzhou plans to make a special place called the Lanzhou Beef Noodles Industrial Park. It will bring together many businesses about making or selling beef noodles. WHAT MAKES THE NOODLES SPECIAL Lanzhou beef noodles are known ... ...
