In the universe, as we all know, there is the Sun, the Moon, the Earth and a good many stars. Through our geography lessons, we know the Earth goes around the Sun, and the Moon goes around the Earth. We have day and night because the Earth keeps turning all the time. When our part of the Earth turns to the Sun, it is day. When our part of the Earth turns away from the Sun, it is night.

    Just because the Moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer.

    The Sun is big enough to give out very strong light. The Moon can't give out any light at all, but it looks quite bright, too. Why? In fact, the light from the Moon comes from the Sun. The Moon looks much bigger and brighter than the stars. But actually the stars are much bigger and brighter than the Moon. They look smaller than the Moon also because they are farther away from the Earth.

    There are many other planets in the universe. But of all the planets, only on the Earth there are living things and people can only live on the Earth, too. But at 9: 00 a. m. on October 15th, 2003, Chinese pilot Yang Liwei was sent up to space. He stayed there for over 21 hours. It was the first time for Chinese to get into space.

China is known as the birthplace of tea,and it has a long history of growing and enjoying this magical plant. 

One famous type of tea is Pu'er,from Yunnan Province. There are two kinds of Pu'er teas: raw and ripe. Raw Pu'er is bitter at the beginning but gets better with age,while ripe Pu'er is made in a special way that gives it a rich flavor(味道). Pu'er tea has been traded since the Tang Dynasty, and it became very popular during the Qing Dynasty. 

Another special tea is Enshi Yulu,a green tea shaped like pine needles,only produced in Enshi City, Hubei Province. This tea has a lovely green color and a delicious,smooth taste. It has been around since the Tang Dynasty and is still enjoyed today for its health benefits. 

Jasmine tea is popular in Fujian Province. It has a lovely floral aroma(花香). The tea was first created during the Song Dynasty and became a favorite of the royal family during the Ming and Qing Dynasties. 

Longjing tea, a famous green tea from Hangzhou,is known for its appearance,aroma,and taste. It has been prized since the Tang Dynasty and was even offered as a gift to the emperor during the Qing Dynasty. White Peony tea,a type of white tea from Fujian province,is another example of China's rich tea culture. It is valued for its health benefits and pleasant flavor

Tea has been used in China for thousands of years. As trade along the Silk Road grew,tea spread all over the world,becoming an important part of many cultures. So,on this World Tea Day, May 21*, let's enjoy the beauty and importance of tea,and the role it has played in shaping our world.

① What is your favorite drink? Do you like cola or other soft drinks? If so, be careful! Soft drinks are not healthy. Soft drinks have much sugar. Too much sugar is bad for your teeth and makes you fat.

② So what can you drink? Don't worry. Here are some healthy drinks. Let's have a look.

③ Water? That's right. It is the best and healthiest drink. Water has no sugar (糖). It won't give you bad teeth or make you fat. How much water should you drink every day? The US research group Mayo Clinic suggests at least eight glasses of water a day (240 ml water for every glass).

④ If you don't like fresh fruits or vegetables, 100% fruit juice might be a good choice. But just don't drink too much. Once you open a bottle of fresh juice, drink it in one sitting. Or it will go bad.

⑤ Milk helps you build a healthy body. Milk is rich in protein (蛋白质), vitamin D and calcium (钙). They are all good for children's bones and teeth.

⑥ So try to choose the healthy drinks. They can be not only good for your health but also delicious. Drink less or never drink those like soft drinks.
