1 . According to a new study, good friends are actually the next closest thing to family in genes（基因）.
U. S. researchers have found that we are more genetically similar to our friends than to any stranger. The study suggested that genes may influence how we choose our friends.
The study looked at the gene information of nearly 2,000 people, who were chosen from a small U.S. town as part of a larger heart study. The study showed that friends share about 0.1 percent more DNA than strangers do.
Besides providing DNA information, participants（参与者）in the study were also asked who their closest friends were. Because all of the participants came from such a small community, it made this group suitable for such studies. It has also led to argument. Friendships in small communities are more probably genetically connected, because such communities usually have fewer kinds of genes.
“I wonder whether the ways used in the study can fully explain the known causes which drive friendships,” said Oxford’s Dr. Rory Bowden.
There was one interesting finding from the study. Some of the genes that friends are most likely to have in common are about smell. “You may really love the smell of coffee. And you’re drawn to a place where other people have been drawn because they love the smell of coffee too,” Fowler explained. “And so that might be the possible place for you to make friends.”

2 . It is important to sort（分类）your rubbish. If you sort your rubbish, you are helping to protect the environment and save our earth. If you don’t do this, the rubbish will be everywhere and we can’t plant things on it. Some kinds of rubbish will pollute the soil（泥土）and the water. For example, the bad things in phones can run out and pollute the ground. Other rubbish, like some parts of pens, can be used to make other things.
Here are four kinds of rubbish:
 Recyclable（可循环的）: Things that can be reused, such as paper, metal（金属）, glass and old clothes. |
 Wet: It is also called “household waste”. “You don’t want these things but pigs can eat,” Guangzhou Daily said. |
 Harmful（有害的): such as medicine, batteries（电池）and phones. If you throw them away, they may pollute the soil and water. |
 Others: It is also called “Dry”. Any waste that doesn’t belong to Wet, Recyclable or Harmful. |

4 . Let me tell you something about sharks. Sharks are among the oldest animals in the world. There are about three hundred different kinds of sharks in the world. Most sharks are about two meters long and live in the ocean.
Sharks can smell something in the water, for example, the blood of animals. That helps them find their food. Sharks mainly eat fish, other sharks and plants in the ocean.
Most sharks bite (咬) people by mistake. They think a person is a large sea animal. When the sun goes down or comes up, sharks are looking for food. So at these times people shouldn’t go swimming in the ocean.
Today people kill sharks for food and their skins. The number of sharks in the world is dropping fast.

6 . Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.
One explanation is the law of overlearning, which can be stated as follows：Once we have learned something, additional learning trials（尝试）increase the length of time we will remember it.
In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.
The multiplication tables（乘法口诀表）are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.
The law of overlearning explains why cramming（突击学习）for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one’s future development.

If you have seen the movie Pirates of the Caribbean（《加勒比海盗》）, you must remember Johnny Depp who played the leading role as the captain（船长）. The Pirates were such successful movies that they climbed to the top of all the most popular movie lists. At the same time, Depp became one of the most popular actors in Hollywood. Depp owns a large number of fans from the young to the old. Right now, Johnny Depp’s time has arrived. He has been named “favorite actor” for seven years in a row. Also, he was chosen as the sexist（最性感的）man alive by People Magazine.
But success never came easily for him. It took a long time to make Depp remembered by the public. He was able to catch people’s eyes with roles in many movies from the family film like Charlie and Chocolate Factory to the serious film like Public Enemies（《头号公敌》）, which was chosen as “best movies” for 2009.
Johnny Depp is a person who never gives up trying a new start. Because of his interesting popularity, Depp was invited to play the screen role as the Mad Hatter in Alice in Wonderland directed by Tim Burton. “Depp can always bring the film surprise and we’re expecting his wonderful performances all the time,” he said.

8 . Artificial intelligence (人工智能), or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.
AI is rapidly catching up with the human ability to read faces. As a result, facial recognition (识别) is used a lot in the world. Chinese police use this technology to identify criminals (罪犯). Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing (网约车) drivers and lets people pay for things with a smile.
AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don’t have this ability. Car makers are testing a light signal system to help them “speak” to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding (让路), it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.
Service Robots also show you how powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.
AI is so powerful that it can help human beings and even replace us in many jobs.

9 . Welcome to your future life!
You get up in the morning and look into the mirror. You look young. In 2035, many people can live to be about 150 years old. So at the age of 40, you’re not old at all. And your parents look the same age as you!
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” can change the color and style as you like. You walk into the kitchen. You pick up the milk, but you hear the voice, “You shouldn’t drink that!” Your fridge remembers the information about the milk. It knows that the milk is not fresh. In 2035, every household appliance(家用电器) is like your secretary(秘书).
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend with your watch. Such “smart technology” is all around you.
So will all these things come true? “All these things will come true, even better.” says a scientist.
I couldn’t agree more with the scientist. I am looking forward to the new life.

10 . There are many things we need to know that we do not learn at school. For example, if we want to (1) use our money wisely, we need to shop carefully. We need to know how to compare the prices of things in different shops. We need to be able to compare the quality of different products. We need to know how to make a choice when we shop.
Knowing how to make such choices is a life skill. We need these skills. They help us to live useful and happy lives.
Some of these choices are small. For example, will I take an apple for lunch or a pair? Will I go to school by bus or on foot? Will I wear the red T-shirt or the blue one to the movies? Other choices are more important. For example, will I eat healthy food for lunch or will I eat junk food because it is tastier? Will I work hard in all my classes or will I only work hard in the classes I enjoy? We make choices like this every day. (2) They can affect the rest of our lives.
Besides, our choices can affect other people. The next time you decide to waste time in class, play a joke on someone or talk loudly at the movies, think about this: who else does your choice affect?
