Stargazing（观星）takes imagination. People who love stargazing see the stars as shining spots in a dot-to-dot（点对点）drawing game. They imagine lines that connect groups of stars called constellations. A constellation is a group of stars that looks like a person, an animal, or an object.
The constellation Orion is known as the hunter, after a hero from ancient Greek stories. To find Orion, first find the Big Dipper. The Big Dipper looks like a huge cup with a long handle. After you find the Big Dipper, turn around. There’s Orion! He is outlined by four bright stars that form two triangles. The tips of the triangles seem to come together. Where they meet, there are three more bright stars.
Different kinds of stars are in the constellation Orion. The star Betelgeuse makes Orion’s right shoulder. Betelgeuse is an Arabic word that means “shoulder of the giant（巨人）.” The star itself is so huge that it is called a supergiant. Its diameter is 400 times greater than that of our sun. Betelgeuse is considered a cool star. It is probably not as hot as our Sun. Rigel is the star that makes Orion’s left foot. Rigel is the Arabic word for foot. Rigel is much brighter than Betelgeuse because it is much hotter. It’s more than three times as hot as our Sun. However, Rigel is just a baby in size compared to Betelgeuse.

【推荐1】The sun comes out in the morning and sets at night, and then the moon rises. Right? Then how come we can see the moon during the day sometimes?
The moon and the sun don’t actually take turns in the sky. The earth goes around the sun, and the moon goes around the earth. All three are spinning (旋转) in space all the time.
The moon moves through the sky night and day. Much of the time, the sunlight is so bright that we can’t see the moon during the day.
The sun is a very hot fire ball, which gives off both heat and light. But the moon is made of rock, it has no fire, and it is not hot or bright at all. What we call moonlight is actually sunlight bouncing off the moon, the same way that sunlight bounces off the glass in the window. They look like they’re lighting up, but they’re really just passing the sunlight along.
How bright the moon is depends on where it is in the sky. If the moon is between the earth and the sun, it doesn’t bounce any sunlight to us at all, and it is very hard to see, even at night. This is called a new moon.
When the moon is behind the earth, it shines very brightly. We call this a full moon. Sometimes, when the moon is very bright, we can see it even during the daytime.

【推荐2】We have always been interested in the moon. 2, 000 years ago, people already knew it moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity (重力) millions of years earlier.
In 1969, moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, though our ideas about the moon may change again, we will still be interested in it.

In the universe, there is the sun, the moon, the earth and many stars. Through our geography lessons, we know the earth goes around the sun, and the moon goes round the earth. We have day and night because the earth keeps turning all the time. When our part of the earth turns to the sun, it is day. When our part of the earth turns away from the sun, it is night. The other part of the earth is always contrary.
Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer.
The sun is big enough to give out very strong light. The moon can’t give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the sun. The moon looks much bigger and brighter than the stars. But in fact, the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are further away from the earth.
Earth is so important because living things and people can only live on the earth. And some countries have sent astronauts to the space to learn more about the universe. At 9:00 a.m. on October 15th, 2003, Chinese astronaut Yang Liwei was sent up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.

①If a child has brown hair and blue eyes, one or both of the child’s parents probably has brown hair and blue eyes. Why? Genes (基因). Scientists know that the way people look is passed down from parent to child by information in genes. But how about other things? If a parent is shy, then would the child also be shy? If a parent is smart, then will the child also be smart? Scientists want to know how much genes and ways of raising can affect (影响) a person.
②One way scientists have studied this question is by studying identical twins who were separated (分开) at birth. Identical twins are twins that look the same on the outside. They also have the same genes on the inside. This is how scientists study their nature. Many years ago, when twins were given away to other families at birth, they didn’t always go to the same family. So, they were separated and raised in different ways. This was of great interest to scientists. Even if the twins had the same genes and looked the same, did they turn out the same as adults? Here are what the scientists have found.
③For some things, such as looks or diseases, the twins turned out the same. Even if one twin drank lots of milk and the other did not, they were of similar heights as adults. Even if one twin exercised and ate healthy food and the other did not, they could get the same disease as adults. Scientists found that how each twin was raised could not change much.
④However, in the case of personality (个性), the answer is not so clear. Some separated twins had completely different personalities and lives as adults. Other separated twins were almost exactly the same. They dressed the same, talked the same, and even had the same jobs—even though they had never met!
⑤In the end, there seems to be no simple answer. As a whole, it seems people become who and what we are because of both genes and how we are raised.

【推荐3】Our grandparents seem to have magic powers sometimes. Give them a Chinese lunar calendar, and they will know what the weather will be like days or even months later. What’s the secret? They are following the 24 Solar Terms, which is an important part of Chinese culture. And on Nov. 30, 2016, the United Nations added it to the list of the Intangible Cultural Heritage of Humanity.
In ancient times, most Chinese people made their living on farms. So, weather changes were important for them. Without satellites, the Internet or the weather broadcast’s help, Chinese ancient people studied the sun’s movement with a sundial (日晷仪). They also paid attention to other natural changes such as air temperature, water and crop growth. As early as the Shang Dynasty, the Chinese ancestors had already established (确立) four major solar terms. During the Zhou Dynasty, eight solar terms marking the four seasons were established. Until the Han Dynasty, the present 24 solar terms was established completely. The terms became their guide to farming work. For example, the solar term jingzhe is when insects wake up from a long sleep in the cold winter. Farmers take it as a sign of warm weather and get busy working.
The 24 Solar Terms is honored as China’s fifth great invention, after papermaking, printing, the compass and gunpowder. Now, people still say, “Do not show your feet after hanlu.” Why? It’s because the solar term hanlu marks the coming of cold days.

【推荐1】What Will Our Life Be Like in 2040?
Welcome to your future life!
You get up in the morning and look into the mirror. Your face is young-looking, In 2040, medical science is better than ever. Many people your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging nanotechnology(纳米技术) treatment. Now, all three of you look the same age!
You say to your shirt: “Turn red.” It changes from blue to red. In 2040, “smart clothes” contain particles(分子) much smaller than the cells(细胞) in your body. The particles can be programmed to change your clothes’ color or shape.
You walk into the kitchen. You grab the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the small computer chip(芯片) on the milk’s label(商标). And it knows the milk is old. In 2040, every food item in the grocery store has a small chip.
It’s time to go to work. In 2040, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Nano-sized “smart technology” is all around you. “Your whole body and surroundings will become part of the same network,” says scientist Ampy Buchholz.

【推荐3】Animation (卡通片绘制) means making things which are lifeless come alive and move.
In the world of cartoon animation, nothing is impossible. You can make the characters you create do anything that you want them to.
A famous early cartoon character was Felix the Cat, created by Pat Sullivan in America in the early 1920s. Felix was an extraordinary (非凡的) cat. He could do all sorts of things no natural cat could do like taking off his tail (尾巴), using it as a handle (把手) and then putting it back.
Most of the great early animators lived and worked in America, the home of the moving picture industry (工业). The famous Walt Disney cartoon characters came to life after 1928. Popeye the Sailorman and his girl friend Olive Oyl were born at the Max Fleischer studios in 1933.
But to be an animator, you don’t have to be a professional (专业的). It is possible for anyone to make a simple animated film without using a camera at all. All you have to do is draw directly on to blank film and then run the film through a projector.
