同学们，你们知道吗？每年的6月1日，不仅是国际儿童节，还是“世界牛奶日”哦！这是世界上唯一用食品命名的国际性节日呢。让我们一起来了解一下“世界牛奶日”吧！

At the beginning， “World Milk Day” was on the second Wednesday of May. But in 2000， FAO（联合国粮农组织）set “World Milk Day” on the day of June 1st. It makes people know more about milk.

On “World Milk Day”， farmers clean the farms up. They stick some pictures about milk foods. Some students and teachers come to visit the farms. People can know more knowledge about milk from the activities.

Milk can stay in our body for more time， because it has more nutrient substance（营养物质）. Drinking milk can make our body work slower， so milk is more thirst-quenching（解渴的） than water.

Long time ago， people put frogs into the milk to keep fresh， just like a fridge（冰箱）. The frog skin is special（特殊的）. It makes the bacteria（细菌） grow slowly.

Truly， milk is full of calcium（钙）， and drinking milk is a way of having more calcium. But it’s not useful for everyone.

Milk is everywhere in our daily life. Nowadays， milk is an important part in some yummy foods， such as cream（奶油）， cheese（奶酪） and butter（黃油）.
