2 . Being a teenager can be hard, for you have to face a lot of difficult problems, but a new program called Nfusion is working hard to help teens with mental(精神的)health needs. Nfusion gives teenagers classes where they study or discuss some troubling subjects. Drugs and bullying(欺凌)are just a few of the topics discussed during the class on Saturday.

"I had a bad attitude, " said 17-year-old Titeana Davis. Davis went through the Nfusion Program last year. The teen, who once had trouble with her attitude towards others, says the program has changed her life. "They taught me a bad attitude is not going to get you anywhere, "said Davis.

Nfusion is a new program that meets teens mental health needs and provides help for their families. The program is designed to help teens aged 14—21 live through a difficult period.

"They're still growing, still developing and still there are a lot of things they don't know how to address. So this is a good program for them to be a part of, " said Lakicha Jemigan, who worked for the Nfusion Program.

Teens like Davis are just a few who have come through the program successfully. Now thanks to Nfusion, Davis says she's looking forward to a bright future. "After I graduate from college, I want to work at a primary school and I want to be a second grade teacher, " added Davis.

3 . A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics (陶瓷制品) to Inuit sculpture.

While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter (神经传导物质) known as the "happy chemical" which helps to lift mood.

According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

"I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. " Some people would do well to recall that just in the 19^th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

4 . Of all the planets, none has captured the world's imagination like Mars. Its reddish colour and changes in brightness over time make the planet an unforgettable sight.

In Cosmos, the television science series from the 1980s, scientist Carl Sagan talked about some traditional ideas about Mars. Some of these ideas are from the English science fiction writer H. G. Well's The War of the Worlds. Others are from the mistaken science of Percival Lowell, the American astronomer who believed intelligent beings lived on Mars. Wells described Martians as threatening. Lowell imagined them as the hopeful engineers of great works. Carl Sagan said that both ideas influenced the public deeply.

Today, Mars continues to excite humans—not as the object of science fiction but of scientific study. Space scientists have collected a wealth of information from spacecrafts that have orbited, landed on and dug into the Martian surface.

The Smithsonian's "Mars Day" offered a chance for people of all ages to touch Mars, or at least a piece of it. Allison and Alycia from Silver Spring, Maryland, brought their children, Grace, Sam, Ryan and Emma. They heard about Mars and its geology from experts. They could see a test version of the Viking landers that reached Mars in July of 1976. They also saw meteorites（陨星）known to have come from the red, or reddish planet. Eight-year-old Sam learned that the ancient description of Mars as red is not exactly right. He said, “It's actually orangish more than red and it's also kind of brown, too.” Emma is six. She learned about the volcanic activity that has shaped the surface of Mars. She said, “The closest thing to Mars—the stuff—is from volcanoes mostly.”

“Mars Day” offered Allison and Alycia's children a chance to learn more about a world that they are very likely to set foot on within their lifetimes.

7 . Monkeys seem to have a way with numbers.

A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.

Here’s how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.

After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.

When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估) a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分) of the smaller number to it.

“This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they’re doing is paying more attention to the big number than the little one.”

8 . Imagine a child standing on a diving board four feet high and asking himself the question: “Should I jump?” This is what motivation or the lack of it can do. Motivation and goal setting are the two sides of same coin.     1     Like the child on the diving board, you will stay undecided.

    2     More than that, how should you stay motivated to achieve the goal? First, you need to evaluate yourself, your values, your strengths, your weaknesses, your achievements, your desires, etc. Only then should you set your goals.

You also need to judge the quality and depth of your motivation. This is quite important, because it is directly related to your commitment. There are times when your heart is not in your work.     3     So, slow down and think what you really want to do at that moment. Clarity(清晰) of thoughts can help you move forward.

Another way of setting realistic goals is to analyze your short and long term objectives, keeping in mind your beliefs, values and strengths. Remember that goals are flexible.     4     They also need to be measurable. You must keep these points in mind while setting your goals.

Your personal circumstances are equally important. For example, you may want to be a pilot but can’t become one because your eyesight is not good enough.     5    You should reassess your goals, and motivate yourself to set a fresh goal.

You will surely need to overcome some difficulties, some planned, but most unplanned. You cannot overcome them without ample motivation. Make sure that you plan for these difficulties at the time of setting your goals.

10 . Rich and Famous

Twenty years ago the most common ambition of American children was to be a teacher, followed by working in banking and finance, and then medicine. But today’s situation is quite different.     1     Instead they most commonly say they want to be a sports star, a pop star, or an actor—in other words, they hope to become a celebrity .

According to experts, young people desire these jobs largely because of the wealth and the fame.     2     Let’s take athletes and singers as an example. Their careers are short-lived. Many athletes’ best time only lasts a few years and singers can have a very limited career. The field that was once the focus of their lives becomes something they have little or no involvement in. As a result, they’ll have a feeling of worthlessness and a lack of control.     3    The truth is quite simple: they have been so far removed from it for so long.

In spite of these disadvantages, there is greater ambition than ever among young people to achieve that status. They are not satisfied just making a living—they want to be rich and famous. Globally, more and more TV shows provide talent competitions where winners can achieve their goals in just a few weeks or months.    4    They unrealistically believe that this lifestyle is easily obtained and leads to great satisfaction.

While many people argue that there is nothing wrong with having such ambitions, others feel that this trend will finally lead to dissatisfaction as more and more people are unable to reach their goals.     5     That means they ignore the simple fact that great effort is needed before success. As a result, many people won’t realize their childhood dreams, which could have a negative effect on their happiness.
