1 . Watermelons were once (曾经) the fruit of only rich families. They are now on the table of common people. And they are many people’s favorite fruit.
Liu Wanlin lives in Xining, Qinghai. She describes watermelons as the “fruit of the people” because they are cheap and common people can buy enough of them.
Liu grew up in the countryside of the dry Qinghai-Xizang Plateau (青藏高原). The weather there is not good for the planting of watermelons. “I never tasted watermelons as a child,” she said. “But ‘freedom of watermelons’ is not a dream now in my place.” People in her place can have as many watermelons as they wish. They get the fruit mostly from Gansu, Shanxi, and Xinjiang.
Song Shaozhe works in a restaurant in Wuhan, Hubei. He says that watermelons are really ▲ at many restaurants as the after-meal fruit, partly because they are cheap.
However, the “freedom of watermelons” didn’t come easy. For many years, scientists have tried hard to improve watermelon breeding (育种). Watermelons become abundant. The large number of watermelons makes them cheaper. Also, thanks to the development of farming techniques (技术), it is possible for people to enjoy the fruit all year around.

4 . What’s the weather going to be like tomorrow? We usually know it by watching the weather report. In fact, we can also know it by looking at nature.
Do you want to know how hot it is outside? Listen to a cricket(蟋蟀)! The more it sings in a minute, the hotter it is.
Spiders(蜘蛛)can help predict cold weather. If you find a lot of spiderwebs(蜘蛛网)inside your house, it means it might get cold soon. Spiders go indoors when the weather is cool, so be careful to look out for them in the dark corners of your home!
Pine cones(松果)can tell if dry weather is coming. Pine cones open their scales (鳞片)when the weather gets very dry. They do this to scatter their seeds(传播种子). When the air is a little wet, they close up to keep their seeds dry. Pine seeds travel by wind, so they have to stay as dry and light as possible.

Germs(细菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system(免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

The population of the Earth is growing faster. It is important that we look after the Earth. We need it!
The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.
In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.
Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

8 . In the West, some people believe that personality can be predicted according to the time of the year the person was bor. From China comes the belief that the year of birth influences one’s personality. In the past century, a new belief ahs arisen: the idea that personality is related to one’s ABO blood type. People with blood type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable to finish what they start. Though this belief continues to be strong, some people question whether it is true.
The blood-type personality theory(理论) started in Japan in 1927 when Furukawa Takehi noticed personality similarities and differences among his workers. This idea soon went out of fashion, but was brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in Japan and is increasingly popular in neighboring countries. Some young Koreans have taken to the theory. A recent study showed 76 percent of Koreans aged between13 and 64 believing in the blood-type personality connection. Though most Asians might believe in the blood-type theory, for many it seems harmless and not something to be taken too seriously.
Is the belief true? The scientists in Asia largely dismiss the belief as a modern-day superstition(迷信). Most studies have failed to find any strong connection between blood and personality. Generally, scientists warn against making predictions or important decisions based on this questionable theory.
