When people reunite with their loved ones, it's usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange，but most of the time they break down in tears.

    Now a group of psychologists from Yale University say they have found the reason why, and that crying tears of joy may well be the body's way of keeping emotional balance. “They seem to take place when people are overtaken by strong positive emotions, and people who do this seem to recover better from those strong emotions,” Oriana Aragon, the lead researcher said.

    Aragon and her fellow psychologists looked at hundreds of participants' emotional responses to different things, including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things —— to cry at happy moments and want to pinch(捏)a cute baby's face or even tell them “I want to eat you up!” But then researchers found that these people were able to calm down from strong emotions more quickly.

    There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols(偶像). People who have just had a big lottery win are often in floods of tears. “These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together.” said Aragon．

    New Orleans, Louisiana, was established as part of the French Empire in 1718.

    Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France, and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it, and the Americans under General Andrew Jackson.

    The riverbed of the Mississippi is constantly silting（淤积）and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.

    Although New Orleans has been a part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which, for many years, was its only law.

    New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The Jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting surface of yesteryear is a busy industrial and port city. Grain and coal come from the Midwest and foreign goods are unloaded here. New Orleans is no longer a sleepy Southern town—but it's still fun to visit.

    I came to the United States ten years ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start.

    Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself.

    One day, however, my son told me that he was sad because his friends would come over and I didn't understand them because I didn't speak English. He was also sad because I could never help him with his homework. That same day, I told myself, "Rocio, you have to start believing in yourself and you will see you can make it."

    The next day, I went downtown to look for a big banner (横幅) in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That's the way I found Chaffey College. The following Monday, I went to ask for information. They told me that summer school was starting that week.

    That's how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had written a story for school. It was about the female they most admired and why. She wrote that I was the person she most admired because I had started going to college. I will never forget this.

A new book called "Battle Hymn of the Tiger Mother" by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.

Many people are against Amy Chua's parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.

Ms. Chua says after her younger daughter shouted "I hate my life! I hate you!" she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children's abilities.

"The debate is about what it means to be a successful parent and what it means to be a successful child," said Stacy DeBroff, who has written four books on parenting. She says Amy Chua's parenting style is not limited to Chinese families. It is a tradi-tional way of parenting among immigrants (移民). They hope to get a better future for their children.

She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.

At thirteen, I was diagnosed (诊断) with a kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

    In my first literature class, Mrs Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, "Mrs Smith, you see, the doctor said I have attention problems. I might not be able to do it."

 She glanced at me through her glasses, "You are not different from your classmates, young man."

 I tried, but I didn't finish the reading when the bell rang. I had to take it home.

    In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots (点), which opened up a whole new world of knowledge to the blind.

    Wasn't I the "blind" in my class, being made to learn like the "sighted" students? My thoughts spilled out (涌出) and my pen started to dance. I completed the task within 40 minutes. Indeed, I was not different from others; I just needed a quieter place. If Louis could find his way to solve his problems, why should I ever give up?

    I didn't expect anything when I handed in my paper to Mrs Smith, so it was quite a surprise when it came back to me the next day—with an "A" on it. At the bottom of the paper were these words: "See what you can do when you keep trying?"

 Lindsey Stallworth, a high school student from Alabama, is on her way to a promising career in paleontology (古生物学) due to an unexpected discovery on family property. For years, she had been collecting fossils on their land in Monroe County, unaware of significant scientific value. However, her teacher at the Alabama School of Math and Science, Dr. Andrew Gentry, a paleontologist himself, took an interest when she showed him her collection.

" Upon examining the fossil shark teeth Lindsey presented, I quickly identified one cr: became eager to learn about its origin," said Andrew.

Lindsey guided her teacher through the rural area where she had unearthed various relics, including shark teeth. Before long, they encountered an especially significant find on the. grounds:a large bone from a 34- million- year- old whale skeleton! This led the pair to launch the huge project of uncovering the rest of the bones. After two months of hard work, they' ve managed to find the animal's skull·(颅骨),

" Assuming the entire skeleton is present, it may require several years for us to have the entire animal back in the lab," Andrew explained.

 Lindsey secured a research scholarship to persist in her fossil- digging expeditions alongside her instructor. Her enthusiasm for the project was at an all- time high, though she had never imagined a childhood pastime would lead her down this road." We would go out and pick up shark teeth and fossil shells, but we never knew anyone that could tell us anything about them," she recalled." We just thought they were cool."

" The Research Fellows Program allows Lindsey to gain real- world experience in scientific research and even present that research at professional conferences," Andrew said." It's a once- in-a- lifetime opportunity for a high school student to stand out when applying to college and maybe even discover a new career path."
