Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.

Healthy eating doesn’t just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others’ healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. After you don’t eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast.
Eat healthy snacks like fruits, yogurt or cheese. We all need snacks sometimes. In fact, it’s a good idea to eat two healthy snacks between your three meals This doesn’t mean that you can eat  a bag of chips instead of a meal.
Don’t eat dinner late. With our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8—10 hours.

When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.
However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.
People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment,a person tried to reach his arm into a cage to get a stick,but he couldn’t reach it. A chimpanzee was in the cage,and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.
小题1:Warneken and his partners worked with ________.
A.young chimpanzee that live on an island
B.18-month-old children who live in Germany
C.kids who are living with adult chimpanzees
D.adult chimpanzees that live on the African mountain
小题2:A new study in Germany suggests that ________.
A.people also share information for good reason
B.children know something at the age of 18 months
C.chimpanzees do good things for no real reason, too
D.humans should develop their abilities 6 million years ago
小题3: Which of the following is NOT true according to the passage?
A.Thirty-six chimpanzees joined in this experiment one by one
B.No chimpanzee saw what the other chimpanzees had done
C.The animals hadn’t met the person before the experiments
D.Chimpanzee gave the person the stick in order to get a reward
小题4:From the passage we know that ________.
A.both chimpanzees and children can find their way to help others
B.chimpanzees will reward good food to other chimpanzees
C.children is more generous than chimpanzees in some ways
D.both chimpanzees and children can do the difficult experiments

New rules and behavior standards(行为规范) for middle school students came out in March. Middle schools are going to use a new way to decide who the top students are. The best students won’t only have high marks. They will also be kids who don’t dye(染) their hair. The following are some of the new rules.
Tell the truth. Have you ever copied someone else’s work on an exam? Don’t do it again! That’s not something an honest student should do. If you have played computer games for two hours in your room, don’t tell your parents you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-loving month in China. Is your school doing anything to celebrate? You should join! In that way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone.
Have you ever quarreled with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you’ll discover Earth Ⅱ some day. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don’t let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren’t for kids, so try to look at web pages that are good for you. You can use the web for fun or homework. Can’t you find any good websites for children? Here are some: Http:// kids.eastday.com, Http://www. chinakids. net. com, http ://www. cycnet.com.

阅读短文,根据短文内容回答问题。

The iPhone 4S is a touchscreen-based smartphone developed by Apple Inc. It is the fifth generation of the iPhone, succeeding the iPhone 4, and was announced on October 4, 2011. Siri on iPhone 4S is like a person assistant. It lets you use your voice to do things on the iPhone. You can just talk to Siri as you talk to a person. Siri understands what you say, knows what you mean, and even talks back.
Say something like “Tell my wife I’m running late.” “Remind me to call the doctor.”“Any fast food restaurants around here?” Siri does what you say, finds the information you need, then answers you. It’s like you’re having a conversation with your assistant.
Siri not only understands what you say, but it’s also smart enough to know what you mean. So when you ask, “Any fast food restaurants around here?” Siri will reply, “I found a number of restaurants near you.” Then you can say, “Hmm. How about French fries?” Siri remembers that you just asked about restaurants for something to eat, so it will look for KFC restaurants in the neighborhood. And Siri is active, so it will question you until it finds what you’re looking for.
When you want to do something, just ask Siri to help you do it. Siri uses almost all the built-in apps on iPhone 4S. It writes texts and sends email messages. It searches the web for anything you need to know. It plays the songs you want to hear. It gives you directions and shows you around. It makes calls, plans meetings, helps you remember and wakes you up. In fact, ask Siri what it can do — it even speaks for itself.
Siri is easy to use and does so much. You’ll keep finding more and more ways to use it.
小题1:When was iPhone 4S announced?
小题2:What is Siri on iPhone 4S like?
小题3:How can you use Siri to do things on the iPhone?
小题4:Why will Siri look for KFC restaurants in the neighborhood?
小题5:What does the writer want to tell us according to the passage?
