1 . Tears well up in people's eyes for a lot of reasons. A teardrop running down the cheek is the ultimate symbol of sadness, but people may also cry because they just cut an onion, or maybe they're trying to blink out an eyelash.
For the most part, tears help maintain healthy eyes. When you blink, basal (基底的) tears clean and smooth the eyes, which helps you to see clearly, according to the American Academy of Ophthalmology. Moreover, reflex (反射性的) tears, or those that happen unconsciously, help clear the eyes of irritants (刺激物), including dust and the gas that's produced when a knife slices a raw onion, said Andre Silva, a doctoral student of psychology at the University of Minho in Portugal.
Emotions can also bring about tears in humans. These emotional tears can serve as a means of nonverbal communication. Silva said, “Babies cry to signal to their mothers that something's up. It's a pure attention call. Some people think that babies are capable of controlling adults by crying, but that idea is false and misleading, as a baby is not conscious of being tricky: In a way, we can consider these tears as being somewhere between basal tears and emotional tears.”
As people grow older, they begin to use their tears to express emotions, such as happiness or sadness. These tears may promote compassion and empathy in others. But beware of people who may use their tears to control others. “Some sensitive people may be easily controlled through the crying of others, and may easily shed tears that can also be used by others to control them,” he said.
So, emotional tears have both advantages and disadvantages. “They are a powerful communication device and a powerful manipulative (操纵别人的) device,” Silva said. Crying also makes it hard for some people to mask their feelings when they're in the middle of an extreme emotional state.

2 . When I was six, Dad brought home a dog one day, who was called “Brownie”. My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games. Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them. We always felt better when she was around.
One day, as I was getting her food, she chewed up one of my Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, “Bad girl, ” she looked down at the ground and then went and hid. I saw a tear in her eyes.
Brownie turned out to be more than just our family pet. She went everywhere with us. People would stop and ask if they could pet her. Of course she’d let anyone pet her. She was just the most lovable dog. There were many times when we’d be out walking and a small child would come over and pull on her hair. She never barked or tried to get away. Funny thing is that she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.
Now many years have passed since Brownie died of old age. I still miss the days when she was with us.

3 . American billionaire Elon Musk has demonstrated a technology designed to use a computer chip inside the head to control the brain. During a video demonstration on Friday, Musk provided details about the system, called Neuralink.
Musk says he hopes the technology can be used to treat neural disorders and help spinal injury victims regain body movement. Musk also believes the system could be used in the future to improve intelligence to help humans keep up with supercomputers and artificial intelligence (AI) technology.
During the show, Musk showed off a model of the Neuralink device. It is about 23 millimeters wide. It is designed to be implanted into a person's skull. Small wires would connect the device directly to the brain.
The Neuralink system is currently being tested in pigs, with plans to seek government approval for human testing sometime in the future.
A pig named Gertrude was also shown during the show. Musk explained that Gertrude had a Neuralink chip inside its head. The device is meant to record nerve activity in the pig's nose and mouth.
Musk said the company had three pigs, each with two chips. He described the animals as "healthy, happy and indistinguishable from a normal pig." Musk said the company was able to predict with "high accuracy" a pig's leg movement on a running machine using data from the chip.
Musk noted that Neuralink first wants to use the device on people with severe spinal cord injuries to help them talk and move using their brain waves. He said he is hopeful that, in the long term, those people could regain "full-body motion."
Some neuroscientists not linked to the company said the presentation suggested Neuralink had made great progress with the technology. However, they warned that many more studies will be needed to test the long-term success of such devices.

4 . The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.
But just as in face to face communication, there are some rules of behavior that should be followed when on line.
For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” if the answer is no, rewrite and reread.
If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so.
It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
| A．It’s natural that there are some people who speak rudely or make mistakes online. |
| B．Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face. |
| C．Everyone was new to the network once. |
| D．The basic rule is simple: treat others in the same way you would want to be treated. |
| E．When you send short messages to a person online, you must say something beautiful to hear. |
| F．You should either ignore the person, or use your chat software to block their messages. |
| G．If you do decide to tell someone about a mistake, point it out politely. |
5 . What kind of amusing activities will you participate in during your life? Will you be spending your free time doing safe sports with little danger or will you always be one of the first people to try the next popular extreme activity? Scientists have been interested in finding out why some people seem to prefer dangerous activities.
Although there are exceptions, researchers have found that in most cases men are less cautious than women. Men often try to impress women by proving that they are courageous and fearless, and they are more likely to take risks when women are watching them or when they are competing against other men.
Research also shows that as people get older they usually behave more responsibly and avoid taking unnecessary risks. In addition, when people are in stable relationships, they seem to be less attracted to daring activities.
Some people seem to be more daring than others, but there are many different types of risks and some people take one type of risk, but not another Psychologists have identified a number of categories of risk. These include financial risks, risks related to health and safety, amusing risks and social risks. Psychologists discover that some people will take risks in one area, but not in another. Just if a person enjoys bungee (蹦极) jumping, it doesn't mean he or she will take chances when investing (投资) money or that he will tell a joke to a group of strangers.
Interestingly, research shows that women take more social risks than men. They are more likely to make career changes as they get older and to express unpopular opinions in business meetings.
Yet, at the end of the day, the likelihood of particular people taking a risk depends on their personalities. In general, optimistic people are more likely to take risks because they focus on the possible positive outcomes of their actions. On the other hand, those with opposite personality are much more likely to avoid taking a chance.

| C．Their problems of finance. | D．The focuses of their work. |
| A．People's sense of taking risks. | B．Risks at people's different ages. |
| C．Different types of people's risks. | D．Risks between men and women. |
6 . Coloring books are no longer just for children! In fact adult coloring books are topping bestseller lists. Why have adults decided to start coloring again?
It is to relieve stress and anxiety.
A trend among adults is to seek out childhood experiences. That's why summer camps adults are cropping up across the country. Perhaps nothing is more equal to childhood than a coloring book. A brand-new coloring book with bright markers, crayons, and colored pencils provide endless possibilities. Adult coloring books are much more detailed than coloring books for children, but the emotions are similar and allow adults to feel as if they are "a kid again".
It is to put down the technology.

7 . Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms. They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem. However, the rise in average water temperatures due to climate change has resulted in more frequent and longtime coral bleaching (白化现象) events that damage their health, causing fish and other sea species to abandon them.
In order to restore this delicate ecosystem, scientists from the UK and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick-starting the natural recovery process of coral reefs and their dependent life forms. The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia. The site is noted to have the largest coral reef system in the world.
“Healthy coral reefs are remarkably noisy places-the crackle of snapping shrimp and the whoops and grunts of fish. Young fish concentrate on these sounds when they're looking for a place to settle,” said Steve Simpson, study co-author and a professor at the University of Exeter, UK.
By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played. “These returning fish, are crucial for coral reefs to function as healthy ecosystems. Boosting fish populations in this way could help to kick-start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world,” said lead author, Tim Gordon.

8 . Why play games? Because they are fun, and a lot more besides. Following the rules, planning your next move and acting as a team member are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating .
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones, which sharpens the hand-eye coordination (协调) needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it — some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.
