Differences between colds and flu
Both colds and influenza(flu)(流感) are caused by viruses and the two illnesses can have similar symptoms(症状). At first it can be difficult to tell the difference. In general, the symptoms of influenza are more serious and last longer than those of a cold.
The main difference between cold and flu symptoms is that flu more commonly includes fever: the fever can be 38℃ or higher and last for 3-5 days. The great tiredness caused by flu can last for weeks while cold symptoms are generally not serious and last for about 1 week. Also, runny nose is more common with cold than flu. Vomiting(呕吐) is another key difference: vomiting is not usually connected with the common cold but can be found in flu.
Although the differences above are generally true, it is impossible to know for sure if it is flu or cold. For example, it is possible to have flu without fever.

Everyone loves holidays and festivals. But do you know a holiday that is celebrated every month? Yes, it's the only holiday that takes place twelve times a year—Bonza Bottler Day.
Bonza Bottler Day is celebrated once a month when the number of the month is the same as the number of the day (Jun. 1, Feb. 2, March. 3). When the number of the year also matches the number of the day and month (August 8, 2008), there is reason to have a bigger celebration.
Elaine Fermont from America came up with the idea for Bonza Bottler Day on August, 1985. She created it when she realized that there were no special chances to celebrate one month. She decide to give herself a reason to have a party and some fun with this special day every month.
Mrs. Fremont held a competition to give the day a special name, which a student from Australia won. When Australians like something, they might shout,” Bonza!”. The word means super, great or fantastic. And “Bottler"is slang(俚语)for something excellent. So the holiday is known as Bonza Bottler Day.
Bonza Bottler Day has no tradition. You are free to do whatever you want. People in offices and hospitals bring food to share. Bonza Bottler Day is a favorite with many schools because it gives a break to students. The holiday can be Candy Day, Ice Cream Day, Be Kind to Classmates Day, No Homework Day, Picnic Day, and the list goes on.
