Some people say dolphins （海豚）are smart like humans （人类）. They can think, understand and learn things quickly. In fact, dolphins have big brain （大脑）-to-body size ratio （比例）, which is second only to humans. Dolphins use brains differently from the way humans do. But scientists say dolphins are like humans in some ways. How?
Like humans, every dolphin has its own “name”. The name is a special sound. Each dolphin chooses a special sound for itself at birth. Dolphins are like people in other ways, too. They “talk” with others in their own groups about a lot of things—such as their age, and how to find food. They also use sounds and body languages to talk. Understanding dolphin words is not easy for humans. No one speaks dolphin words, but some scientists are trying to learn.
Dolphins are also social （社会） animals. They live in groups, and often join others from different groups to play games and have fun—just like people. Scientists believe playing together is something only smart animals do.
Both humans and dolphins make plans for getting things they want. For example, when there are fish near a boat, dolphins jump high to ask the fishermen to put their nets （网）, and then the men can catch a lot of fish. Why do dolphins help the men? Because they can get some fish that run away from the net.

【推荐2】There are about five thousand different kinds of ladybugs(瓢虫) in the world. They come in many different colours like blue, yellow, white, orange and black.
In many cultures, people think ladybugs can bring good luck. Most people like them because they are beautiful and not bad for people’s health. But farmers love them because they eat plant-eating insects. One ladybug can eat up to 5,000 small insects in its lifetime!
Ladybugs are colourful for a reason. Their colours tell other animals, “Eat something else! I taste terrible.”
Ladybugs are happy in many different habitats, such as forests, cities and along rivers. Ladybugs like to keep warm. When the weather turns cold, they look for a warm place to hibernate (冬眠), such as inside houses.
Here are some other facts about ladybugs:
● Though most ladybugs eat small insects, a few kinds eat plants.
● Ladybugs will clean themselves after a meal.

In the animal world, the mother is usually the parent that does the most for the child. She gives birth to it and often raises it on her own. However, there are several aquatic animals that are turning this idea upside down.
One of the most interesting examples of an excellent ocean dad is the sea horse. The female lays her eggs in a pouch on the front of a male sea horse. When the eggs finally hatch (孵化), the dad gives birth by pushing the tiny new sea horses from the pouch.
Another father with a pouch is the Darwin’s frog. The female lays eggs and the male guards them for about two weeks. When the tadpoles (蝌蚪) come out of their eggs, the father puts them in the big pouch of skin under his chin, where they stay until they are ready to jump out into the dangerous world.
The clown fish was made famous by the Disney film Finding Nemo. After the female clown fish lays eggs, the male protects them until they hatch. That’s not all. If the mother fish dies, the dad can turn into a female and be the new mom of the family.
Another great ocean dad is the emperor penguin. These dads keep the eggs on top of their feet under a thick fold of warm skin. During the next two months of the Antarctic winter, these fantastic fathers go without food as they keep their eggs warm.
While each of these fathers is very different, they all take responsibility for their children. These dads of the water make sure their kids have a safe place to grow so they will have a good life in the future.

【推荐1】Thus I got to know an important fact that the planet the little prince came from was hardly any larger than a house!
I was not,however,shocked so much. I knew very well that there are some planets which are so small that one has a hard time seeing them through the telescope. When an astronomer discovers one of these planets,he does not give it a name. Instead,he gives it only a number. He might call it,for instance,“Asteroid (小行星) 325”
I have good reason to believe that the planet from which the little prince came is the asteroid called B-612. It has only once been seen through the telescope. A Turkish astronomer discovered it in 1909. On making his discovery, the astronomer had presented it at the International Astronomical Conference but nobody would believe his discovery because he was dressed in Turkish traditional costurne. At any rate, grown-ups are all like that. Fortunately, however, in 1920, when the astronomer gave his presentation all over again, dressed in impressive European costurne, his report was accepted by everybody.
I have told you these details about the asteroid because I need to reveal the ways of grown-ups. Whenever you tell them that you have made a new friend, they don't ask you any questions about important matters at all.
They never ask you, "What does his voice sound like? What's his favorite game? Does he collect butterflies?" Instead, they ask, "How old is he? How many brothers does he have? How much money does his father earn?" They think they have learned about him through these figures only.
Therefore,you'd better not say to the grown-ups,“The evidence (证据) that the little prince existed is that he was charming,that he laughed,and that he wanted to have a sheep. If anybody wants to have a sheep,that's the evidence that he exists." There is no use to tell them in that way. They would shrug their shoulders and treat you like a kid.
Grown-ups are like that. Children should always show great patience towards grown-up people.
1. According to the writer, where did the little prince come from?| A．A small house. | B．Asteroid 325. |
| C．A large planet. | D．Asteroid B-612. |
| A．Because the astronomer was not thought to be properly dressed. |
| B．Because the astronomer didn't provide enough evidence. |
| C．Because the grown-ups didn't like the astronomer. |
| D．Because the astronomer was from Turkey. |
| A．They show great patience towards kids. |
| B．They care a lot about numbers. |
| C．They take kids' words seriously. |
| D．They care about the interest of person. |
| A．He was charming. | B．He laughed. |
| C．He wanted to sleep. | D．He wanted to have a sheep. |
【推荐2】Can you remember the day when you spoke your first word? If you can, you are not usual. Try to imagine what the first few months of your life were like. I am sure you just spent most of your time eating, sleeping and crying. As you grew older, you were awake more of the time. It took your parents more time to play with you and talk to you. You watched and listened curiously. You began to know that people made certain sounds to go with certain things.
Then you began to try making the sounds you heard. And step by step you were able to make the right sound for one thing.
On that day you came to understand the secret of language. The secret is that a certain sound means a certain thing. One sound might be as good as another. But it is no good as a word unless everybody agrees on its meaning. Only when a group of people use the same set of sounds of things, can they understand each other. Then and only then do these people have a LANGUAGE.
After you found the secret of language, you learned words. Some of the words meant things, such as BOOKS, CHAIRS and SHOES. Some words meant doing things, such as GO and SWIM, and other words described things, such as GOOD and DIRTY. Soon you learned to put words together to express your idea, such as “I want to go out and play with my friends.” This is language. By means of language people can communicate. So we say languages are means of communication.

【推荐3】Do you often listen to music at loud volumes（音量）?
Loud noise is harmful to the inner(内的) ear. Most of us are born with about 16,000 hair cells(细胞) in our inner ears. These cells notice sounds. However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die.
Some people might think that their music isn’t all that loud.
The “safe level” for most sound is below 80 dB for up to 40 hours a week. A level of 80 dB is about equal to (相当于) the noise of a subway.
Here is some advice on safe listening.
| A．This is what causes hearing loss. |
| B．But this can depend on where you are. |
| C．The United Nations has standards for safe listening. |
| D．Over-the-ear headphones are better than in-ear ones. |
| E．You should know that this habit is bad for your hearing. |
【推荐1】Now, some women are spending a weekend at Mother's Camp. There, husbands and children are not allowed. Why would a woman want to take a vacation without her family? Some women say they need time to be alone.
At Mother's Camp a woman has room to herself. She can sleep, read or watch TV. No children will ask, “Mom, what's for dinner?” No husband will say, “Oh, dear, I can't find any clean socks.” In fact, almost fifty percent of women in the United States work outside the home. Many of them work full-time and then come home to a second job-taking care of their homes and families. These working women say one of their biggest problem is housework.
In the United States, working wives do about 75% of the housework. Many of their husbands say they want to help. But then they burn the rice or they can't find the pans. They ask so many questions that their wives decide it is easier to do the job themselves.
Some women go to Mother's camp just to get a break from housework. They enjoy warm, sunny weather, walking, swimming or boating in a clear blue lake and sing songs around the campfire. They relax away from home. They have a really wonderful vacation at Mother's Camp.

Look at these pictures of cute animals. Can you guess what they are used for? Are they toys? Actually, these cute “animals” are huabobo, which has been a popular traditional food in Northern China for more than 300 years.
Usually, huabobo is four or even six times bigger than mantou. It has become a necessary part of an important event. To make it, women use tools like knives, scissors and pens to shape the dough (生面团) into ducks, dragons, peaches, etc. before having them steamed (蒸). Then they color them.
▲ For example, huabobo in the shapes of rabbits and tigers can usually be given to children to express the wish that a boy will be as strong as a tiger and a girl as lovely as a rabbit.
Huabobo tastes good, but most huabobo shops only serve them locally. That problem caught the attention of Zang Chaiyuan, a 25-year-old girl from Yantai, Shandong. Then she managed to find a way to keep huabobo for over two months, making it possible and convenient to send it to other cities.
Zang wants to introduce huabobo to more people. Her love for huabobo has made her create many new shapes, which enjoy high popularity among the young. What’s more, she uses natural fruit and vegetable juice to color huabobo to make it healthy.
Using her creative works, Zang has managed to breathe new life into the traditional huabobo, allowing more young people to understand and taste this traditional food.

【推荐3】Everyone must go to bed early and get up early, or we won't be healthy and clever. Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every day. If you don't go to bed early, you won't have enough sleep. Then you can't think properly(正确地) and can't do your work properly. You'll not be clever. Some people go to bed late and get up late. This is not good for them. We must sleep at night when it's dark. The dark helps us to sleep well. When the daytime comes, we must get up. This is the time for exercise. If you don't exercise, the body becomes weak. Exercise keeps a strong body. Exercise helps the blood flow(血液流动) around inside the body. This is very important. Blood takes food to all parts of our body. The brain(头脑) also needs blood. We think with our brains. If we keep our body healthy and take exercise, we can think better.
