Do you know about Artificial intelligence（AI）（人工智能）? Al is growing very fast now.
We are living in a world that depends more and more on Al. AI is a group of techchnologies that help machines get, understand and use information to do tasks.
AI’s recent developments have got a lot of social attention. Some people have welcomed AI. Because it makes things possible. For example, Al will have a big influence on areas like medicine and engineering. But this attention has also produced a lot of fear.Especially, many workers are worrying that Al could make them lose their jobs.
According to a recent study, nearly five percent of jobs will disappear because of Al. In some industries, Al is already doing the work that people used to do, such as assembling(装配) cars, digging the coal and lifting goals. Self-driving cars and trucks controlled by AI will also take away the driver’sjobs in the future.
On the other hand, Al will also create many new jobs for people. More people will be needed to write programmers for Al systems( 系 统 )and they will set up and work on them, too.
Meanwhile, jobs that require feelings, excellent communication skills with people will not be replaced(取代)by Al. These include jobs in fields like teaching, nursing and personal trainig.
Al is here. It is changing how people live and work in many ways. That makes Al important to watch, not to fear.

Oink! The Year of the Pig is coming. How much do you know about pigs? Do you like them? Many people don’t because they believe that pigs are naturally fat, lazy and dirty. But are any of those things true?
It is true that pigs are fat. They eat a lot. But they are useful to us. We get more than just pork from pigs. We can use their skin to make shoes. We can use their hair to make brushes. Pigs also provide us with ingredients for drugs like insulin (胰岛素). Insulin can treat diabetes (糖尿病)
People sometimes say, “You are as stupid as a pig.” But pigs are not stupid. In fact, pigs are one of the 10 smartest animals. They have a good memory and can tell different shapes apart. Many experts think pigs are easier to train than dogs or cats. In France, people teach pigs to find truffles (松露). With their good sense of smell they can find truffles even faster than dogs.
When you see pigs, they are usually in dirty water or mud. That’s because pigs have no sweat glands (汗腺). On hot days, they have to cool themselves in water or mud. This keeps insects of them as well. Mud can also protect their skin from sunburns.
These stereotypes about pigs often make us hold a negative view about the animal. For example, if someone eats a lot, we say that they have “pigged out”. If someone’s room is very mess, we might say his or her room looks like a pigsty (猪圈).
But people in ancient China really liked pigs. People thought the pig’s big head and ears were a symbol of good luck. If someone had a round and chubby (胖乎乎的) face, he or she was thought to be blessed (有福气的). People also believed the animal stood for wealth, as humans use every part of the pig. Piggy banks are a symbol of this. Most children have a piggy bank that they can use to save money.
1.People can use pigs’ skin to ______.
A.make clothes. B.make insulin. C.make shoes D.make brushes
2.According to the passage, pigs can ______.
A.tell one hundred different colors apart.
B.find truffles with their good eyesight.
C.be of great help to people like dogs.
D.get away from insects with their masters’ help.

A.fixed ideas B.feelings C.mistakes D.descriptions

Many people think of the brain as a mystery. They don’t know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb—and stays that way in the whole life. But new research shows that the brain is more like a muscle（肌肉）—it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can’t lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That’s because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink（收缩）and you get weaker. That’s why people say “Use it or lose it!”
But most people don’t know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex（皮层）of the brain are billions of tiny nerve（神经元）cells（细胞）,called neurons. The nerve cells have branches connecting them to other cells in a complicated（复杂）network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do —like speaking a foreign language or doing algebra（代数）—seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals’ brains. They found out that animals that lived in a challenging environment were more “perspicacious”—they were better at solving problems and learning new things.
1.According to the first paragraph, .
A.the function（作用）of our brain is like that of the muscle
B.until now it’s impossible to explain the brain’s mystery
C.many people believe one’s intelligence is naturally determined（决定）
D.one’s brain grows stronger as the age increases
2.What is Paragraph 3 mainly about?
A.The complicated structure of the brain.
B.How changes in the muscles affect the brain.
C.The importance of the brain.
D.How the brain becomes stronger by learning new things.
3.What does the underlined word “perspicacious” in the last paragraph probably mean?
A.Strong. B.Smart. C.Popular. D.Active.
4.The paragraph that follows the passage will most probably talk about .
A.the differences between animals’ brains and humans’ brains
B.the relation between human brains and muscles
C.scientists’ findings about animals’ brains
D.how to make your brain smarter through self-development
