Question: Article: On October 23, 2011, David Pologruto, a high school physics teacher, wasstabbed by his smart student Jason Haffizulla. Jason got straight A's and was determined to study medicine at Harvard, yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed wouldundermine his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed his physics teacher. How can someone as smart as Jason do something so dumb? Studies show there is little or no correlation between IQ and emotional intelligence. During my early university years, I regarded myself as an intelligent guy. I got good marks in mathematics, physics, and other subjects. I thought such skills would surely give me a bright future. After one year of study with decent marks, I began to see two major classes of students. The first category of students turned up to few lectures, partied every weekend, enjoyed a great social life, and did minimal work to pass courses. The second category of students were intelligent and hard workers who got good grades and were very focused on their studies. Surely would these intelligent and hard-working students find the great jobs before the other lazier class of students? Not so. Students are often shocked upon graduation that their qualifications are not as important as they once thought. Graduates enter the workforce only to realize that co-workers hate them and less intelligent people are the ones receiving promotions. Educational skills are useless in some industries when interpersonal skills are absent. You can have great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in whatever challenges you encounter. It's not that people dislike you because of your intelligence; it's that people dislike you because you're rude and not understanding. The intelligent person with poor communication skills is insensitive or unaware of others' emotions.
Answer: he got a worse mark than usual

Answer: Jason Haffizulla stabbed his physics teacher because _ .

Question: Article: In ancient Greek mythology we learn about a young man named Narcissus. He was so beautiful that he fell in love with his own reflection . He became obsessed , but soon realized that what he loved was not real. As a result, he became sad and died. In the place where he had stood appeared a soft yellow flower -a narcissus. This is where the word "narcissism" came from. Unfortunately, narcissism is often used to show disapproval because it is usually used to mean being self-centered and not caring about others. However, part of the reason that narcissism carries these negative meanings is that many people admire themselves in an unhealthy way. But the truth is that good self-love is necessary for our mental health, scientists say. A study published 10 years ago shows that low self-esteem is responsible for many social problems, and it can affect teenagers seriously. When they feel less confident and not as good as their classmates, teenagers are more likely to suffer from depression, commit suicide, get pregnant and bully others, according to the BBC. The other reason that narcissism is considered an ugly thing is because we are taught that we should care more about others than ourselves and that it's better to give than to receive. Thinking about others is the right thing to do, without question. But psychologists say that the love of others is actually based on self-love. If you see yourself as an unpleasant stranger, how can you be capable of making friends with anyone else? After all, you are closer to yourself than anyone else. After years of study, scientists also found that parents play a big part in building a child's self-belief. Only if the parents approve and accept their children, do they feel loved and learn to love themselves. The next time you look in the mirror, try to tell yourself that you are one of a kind. Pick out your best qualities and be proud of yourself.

Question: Article: Zhu Haoyu, 18, a history major, wears his iPod everywhere on campus. The freshman has it going out for a walk, visiting the library or lying in bed. However, he found that his habit is like displaying a big "Do not disturb "sign for himself. As time slips away, he has begun to regret not having conversed much with his peers around . "As I put the little buds into my ears, I'm in a universe of my own, forgetting all troubles in the real world," said Li. The MP3 player is one of a number of gadgets --starting with the Sony Walkman, which led to the iPod, iPhone and iPad --that give people the ability to shut themselves off from world around them. Youngsters delight in handset technology. In public, students chat on their cell phones, stopping only to talk briefly to friends. On buses or trains it's common to see youngsters with PlayStations instead of playing poker or sharing jokes or games. And during airline flights, people watch episodes of US TV dramas on their iPads, rather than talking. The recently published an article saying that headphone wearing culture is making us anti-social. "Half of humankind is wired to a parallel universe that leaves them ignoring their surroundings and fellows," wrote Tom de Castella. Actually, it's a decade since Apple unveiled the iPod, which promised "1,000 songs in your pocket". In 2007 more than half of Western residents were using an iPod or MP3 player. Entertainment is on offer in all surroundings, not just at home. But in the meantime, it has created barriers between us. Many people subscribe to the view that the headphone culture is creating a "spoilt, selfish generation that lacks civic culture". However, many users of portable MP3 players argue that the device, as a mind drug, helps them relieve stress by escaping for a while. It is also said to be able to help some students concentrate on work or study. "If you want to get away from the hucksters on the way, just start listening to your player," said Liu, a freshman. "They do not approach people with headphones on." This might also mean he's blocking those who want to ask him for the directions. Experts, however, say that short contacts or mini conversations with strangers are helpful to our mind. Many experts warn that it is dangerous to lose touch with people in our lives.
