　　What are the parts of a flower?

　　Flowers can have male parts and female parts. The female parts make eggs that become seeds. The male parts make pollen. Pollen is a powdery material that is needed by the eggs to make seeds. To make seeds, pollen and eggs must come together. The wind, insects, and birds bring pollen to eggs. Many animals love flowers’ bright colors. They also like a sugary liquid in flowers. This is called nectar. While they drink nectar, pollen rubs off on their bodies. As they move, some of this pollen gets delivered to the female flower parts.

　　Over time, the female parts turn into fruits that contain seeds. Animals often eat the fruits and the seeds pass through their bodies as waste. The animals do no know they are working for the plants by planting seeds as they travel to different places!

　　Useful words and Expressions:

　　1. flowering 開花的

　　2. pollen 花粉

　　3. powdery 粉狀的

　　4. sugar 含糖的，甜的

　　5. nectar花蜜，甘露

　　6. rub 磨擦

　　Water is very important to us. Factories and plants need water for industrial uses and large pieces of famp3land need it for irrigation. Without water to drink, people die in a short time.

　　Today most water sources are so dirty that people must purify water before drinking. Water becomes dirty in many ways: industrial pollution is one of them. With the development of industry, plants and factories pour tons of industrial wasters into rivers every day. The rivers have become seriously polluted, and the water is becoming unfit for drinking or irrigation. The same thing has also happened to our seas and oceans. So, the problem of water pollution is almost worldwide.

　　Scientists of many countries have done a lot of work to stop pollution. The polluted water in some places has become clean and drinkable again. Perhaps one day the people in all towns and cities will be drinking clean water. That day, we believe, is not very far off.
