How time flies! A week has passed in the twinkling of an eye. I really miss the time when I was a little girl and the time when I thought a day was so long.

Though the weather was not good today, the average temperature was about 15 degrees centigrade. I went out just with a thin coat, but I knew I could not be happy earlier because from tomorrow the weather would be cold again, just as per the weather forecast.

I was not so busy this afternoon which was so different with last Friday, so I was listening to some English teaching radio show and learning something new. I will share you these in my later diary.


生词难词：

1.in the twinkling of an eye: 一刹那；转瞬之间；眨眼的功夫

2. degrees centigrade/ Celsius: 摄氏度 用符号“℃”表示

零下1摄氏度 minus one degree Celsius/minus one degree centigrade

0度是：zero degrees

The average temperature here in the day is 15 degrees centigrade.

Fahrenheit 华氏度 用符号符号"℉”表示


华氏温标是1714年德国人华伦海特Gabriel D. Fahrenheit制定的——

摄氏温标是1742年瑞典天文学家安德斯·摄尔修斯Anders Celsius制定的——

目前世界上包括中国的大多数国家都使用摄氏度，

世界上有三个国家（美国、缅甸和利比亚）通常使用华氏度，较少使用摄氏度(℃)


华氏度=（9/5x摄氏度）+32

摄氏度=5/9（华氏度－32)


国际上用得较多的温标有华氏温标(°F)、摄氏温标（°C）、热力学温标(K)、列氏温标（°Ré）、兰金温标（R）和国际实用温标。
