    Look at the koala! It is 1 lovely that I want to touch it. How much do you know about koalas, especially a baby koala? Let's look at it.

    A newborn koala is smaller than a peanut. For the first few months the baby 2 inside its mother's pouch(育儿袋), and drinks its mother's milk.

    By the age of 5 3, its eyes are open and it can look out 4 the pouch. It still stays there.

     About six months after the baby is born, it leaves its mother's pouch for the 5 time for a short time, but it hangs onto its mother's back.

    It is now about 500g. It comes in and out of the pouch. It keeps very close to its 6and returns to the pouch within a few minutes. Gradually the baby will stay out longer.

    By 12 months old, the baby wants to eat only eucalyptus(桉树) 7, no more its mother's milk. The mother koala begins teaching her baby which eucalyptus leaves are 8 to eat.

    A one-year-old koala can 9 on its own, 10 it doesn't often do that. Most young koalas stay with their mothers until they are two or three years old.

    Do you like blueberries? But maybe you don't know blueberries well.

    Farmers often grow them on bushes(灌木丛) in the field. A blueberry is small and round. Many blueberries can grow on one bush. At first, the blueberries are green. You can't eat the green berries. A lot of sun and rain help them become sweet. When the berries become blue and big, they are ripe and sweet.

    After the blueberries are ripe, people put them into boxes and bring them to stores and supermarkets. People buy the blueberries and take them home to eat. After they wash the berries, they eat them one by one. Some people like to cook with blueberries. They make blueberry muffins(松饼) and pancakes. They like to make blueberry juice. Others like to make blueberry ice cream. It is very cool!

    Preparation is the key to successful travel. In order to have a pleasant trip, you must prepare well before you start off. The most important thing you should do is to pack(把东西装入) your bags with useful things.

     About all, ★. For example, if you travel to another country, you must remember to take your passport with you. You should also take clothes that are suitable for the climate, such as a sweater, a swimsuit, a raincoat and suitable shoes. One more thing, never forget to take some medicine with you in case (以防) you get sick.

    In addition to these things, you should remember to take a camera so that you can take pictures of the places you visit. To keep in touch with your family and friends, you should carry a cell phone, too. It would also be good to carry a directory with all your family's and friends' telephone numbers in it. That way, if something goes wrong with your cell phone, you can still get in touch with them by using a public telephone.

    After a long day's study at school, you are very tired. So after school you go home to relax. When you get home, a robot greets you. He's happy to see you and helps you take your school things to your room. He listens to you talk about your school life and tells you a new joke. And he tells you to call your cousin and to say happy birthday. And then he helps you with your homework.

    This is your future, and the robot's name is NAO. NAO has a small body, big eyes and a large head. He can walk and dance. He listens and talks, and he even learns and thinks for himself. His creators(创造者) predict that the robot will be in people's homes before 2040.

    This $16,000 robot knows who you are. NAO can even express emotions(表达情感). He is a self-guided robot. A self-guided robot can sense(感觉), think and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, he can't act. Another robot can move and sense things, but he can't think for himself. These aren't self-guided robots. But NAO can do them all.

    Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana. Last year, he taught his students about the world's rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.

    Destruction of the world's rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres per minute! As part of a class project, Myers' students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.

    So last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. "The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us," one of the students said. "It was a great learning experience for all of us," said Myers.

    Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture. During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica's active volcano.

    Myers hopes to make the trip every year with a different group of kids.

    Do you like drinking coke, coffee, juice or milk? Do you often drink them instead of water? However, of all the things we eat and drink, water is the most important. Not all of us understand this but it is quite true. Human body can go without food for a long time, but two or three days without water usually makes people die.

    Many people do not understand how much water the human body needs to work well. What is true is that many people do not drink enough, especially in hot weather. Most people drink only when they are thirsty but often need more water after they take exercise.

    Does anyone know what is the 65%-75% of human body? It is water. If we do not have enough water, we will feel tired and become ill. So, do you know what the best drink is? It's water.
