Stop reading for a minute and think about what you see when you look up at the sky on a clear night. You probably see many stars(星星). Long long ago, farmers watch some stars to know when to plant their crops. Travellers did so to find their way in the dark. Today stars are still important to some people.

    Scientists find that most stars are very big. In fact some stars are so far away that it would take millions of years to get to them even by spaceship.

    Another thing we know today about stars is that some are made up of(由……组成) hot gases. The gases are so hot that they send out light. If you watch a star carefully, you may notice that it twinkles(闪烁) sometimes. As you may understand, light from a star must shine through the air before you can see the star. Air is always moving, it makes light from the star move back and forth. When the light moves, it makes the star twinkle. Stars also have different colours. The colours of a star depend on how hot it is. To our surprise, the cool stars are red and the hottest stars are white.

    What is an egg? Birds and fish give birth to many babies at one time. They can do this by laying (产) many eggs. The baby birds or the baby fish stay in eggs until they are ready to be born. What do eggs look like? When you make a fried egg, you can see a yellow part and a white part. The yellow part of the egg becomes a chick. The chick eats the white part until it comes out of the egg.

    What is a fruit? Why do plants have fruits? A fruit is the house of seeds (种子). Plants grow flowers to make fruits. Fully grown fruits fall down. Then, the seed grow root (根) under the ground. What happens next? Another plant grows! Usually seeds grow inside of a fruit, but strawberry seeds grow outside of the fruit.

Twenty percent of all the water that goes into oceans around the world comes from one river — the Amazon.

The Amazon River{#blank#}1{#/blank#}from the Andes Mountains in Peru.It travels about 6，400 kilometres to the Atlantic Ocean.It is the largest river in the world.It is{#blank#}2{#/blank#}the second longest.Most of the Amazon's water comes from rain.During the rainy season, parts of the{#blank#}3{#/blank#}are 190 kilometres wide.

With a history of more than 1，800 years,dumplings are a traditional Chinese food. They are also a must for Chinese New Year. They are popular in China,especially in north China. Even some foreigners are interested in1 them. 

Chinese dumplings2 be made to look like ancient Chinese gold or silver ingots (银锭). It's said that the more dumplings you eat3 Chinese New Year, 4 money you can make in the coming year. 

People usually put minced meat (绞碎的肉) and vegetables in thin round dough skins (面皮) to make dumplings. Popular fillings are minced pork,fish,chicken,beef,and vegetables. People cook5 in different ways. 

Some people believe 6 people shouldn't eat sauerkraut (酸泡菜) dumplings during Chinese New Year. Because it means7 poor and difficult future. People like8 Chinese cabbage dumplings because it means one9 a lot of fortunes in the future. 

When making dumplings,there should10 a good number of pleats (褶) so that they will bring wealth. Sometimes a coin is put in dumplings,and the one who eats it is supposed to become wealthy.
