GPA平均学分绩点
You probably know that we've traditionally used letter grades to assess students in the United States. These include an "A" grade for those who do very well. "B" and "C" grades are for those who do good to average. Those who get a "D" or "F" grade typically do not pass the course.
These grades are translated into numbers, which make up a GPA. The highest grade point average is 4.0, and is for students who receive all A grades. This system may sound complicated.
How are students assessed in your country? Do they get a letter grade, or a number from 1 to 5? Perhaps, they receive a percentage.

2005年的时候，法国爆发了一次 “沙门氏菌感染”， 104名婴儿被感染，2名致死都是因为喝了用低温水冲泡的奶粉。
后来，联合国粮食及农业组织（FAO）与世界卫生组织（WHO）才联合建议：
应使用温度不低于70°C的水来冲调婴儿配方奶粉，以杀死奶粉中的致病菌。
那水温高会不会导致营养流失呢？
针对家长最关心的这个问题，世界卫生组织专门进行了实验研究，
结果发现，水温在70度时，蛋白质和脂肪这些营养物质没有任何损失，维生素C会有少量的损失，不过奶粉中加入的维生素C含量本来就很充足，这点损失不足挂齿。
所以，从宝宝的健康安全出发，还是用70度以上的水冲奶粉更合适。#内行才知道##知识分享大会#
