Students who date in middle school have significantly worse study skills, are four times more likely to drop out of school and report twice as much alcohol and tobacco use than their single classmates, according to new research from the University of Georgia. "Romantic relationships are a symbol of adolescence , but very few studies have examined how adolescents are different in the development of these relationships." said Pamela Orpinas, study author and professor in the College of Public Health. Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school. "At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills," according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit, being well organized, finishing homework, working hard and reading assigned chapters. "Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying." "Dating should not be considered a ceremony of growth in middle school."Orpinas concluded. When doing his study, Orpinas _ . A) followed a group of students of 6th and 12th grade B) found that the students' study skills have connection with their frequency of dating C) completed questionnaires about the students' academic efforts D) completed a survey and a report each year

Rush hour traffic is a problem in many big cities around the world. Commuters rush to and from their jobs in cars, buses, subways, trains, and even on bicycles. Large cities in the United States have two rush hours--one in the morning and one in the evening. But in cities in other parts of the world, there are four rush hours. In Athens and Rome, for example, many workers go home for lunch and a nap. After this midday break, they rush back to their jobs and work for a few more hours. In Tokyo, there's a big rush hour underground. Most of the people in Tokyo take the subways. The trains are very crowded. Subway employees called packers wear white gloves and help pack the commuters into the trains when the doors close. They make sure that all purses, briefcases, clothes, and hands are inside the trains. In Seoul, many commuters prefer to take taxis to get to work.. To hail a cab,many people stand at crossroads and raise two fingers. This means they'll pay the cab driver double the usual fare. Some people even raise three fingers! They'll pay three times the normal rate. Streets in Rome are very crowded with automobiles and mopeds during rush hours. The city can't make its streets wider, and it can't build new highways, because it doesn't want to disturb the many historic sites in the city, such as the Forum and the Coliseum. It took the city fifteen years to construct a new subway system. Construction had to stop every time workers found old artifacts and discovered places of interest to archaeologists . In many big cities, there are special lanes on highways for carpools. These are groups of three or more people who drive to and from work together. They share the costs of gas and parking and take turns driving into the city. Getting to work and getting home can be difficult in many places around the world. Rush hour traffic seems to be a universal problem. Most of the commuters in Tokyo _ A) take subway trains to work B) are packers C) take taxis to work D) carry briefcases to work

Q: Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas , luxury cars and twinkling lights from the shopping center that he sees through the window. Yang works for a software company in Zhongguancun. He dreams of such a life, away from poverty, and that hope has kept him in Beijing for three years since he graduated from university. Soon Yang squeezes his way off the bus to the reality of his life: his home--a 10-square-metre room that costs 550 yuan(81 US dollars) or about one-fifth of his salary in rent every month. It's very cold inside the house as it has no central heating system. He has to stand the long and cold winter. Determined to achieve his dream, Yang says he has changed jobs "numerous" times in the past three years and is considering quitting his present job. Yang's frustration over his life as a migrant is shared by many other graduates that have moved into big cities. Together they have come to be called the "ant tribe", a term created by Chinese sociologists to describe the struggles of young migrants, who, armed with their diplomas, flood to big cities in hopes of a better life only to put up with low-paying jobs and poor living conditions. They share every similarity with ants. They live in colonies in crowded areas. They're intelligent and hardworking, yet unknown and underpaid. The term, sociologists have said, also reflects their helplessness in a world governed by the law of the concrete jungle--only the strongest survive. A survey in Ant TribeII found nearly 30 percent of the "ants" are graduates of famous key universities--almost three times the percentage of 2009. Most have degrees in popular majors, such as medicine, engineering, economics and management. In addition, 7.2 percent of the "ants" have at least a master's degree compared to 1.6 percent in 2009. Most said the economic recovery did not really improve their financial situations, and 66 percent said their incomes fell short of their expectations, the survey also found. For two... . Which of the following best describes "ant tribe"? A) It refers to the group of low-income graduates living in embarrassing conditions. B) It refers to the people who work hard like ants but are paid little. C) It refers to the sociologists and scholars researching into some social phenomena. D) It refers to some well-educated people who can't survive in society.
A: A

In 1896, Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class and the same interest in physics brought them together and they became good friends. Before long they fell in love. In 1903 when Einstein was 24, he married Merits, who was 4 years older than he. After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Merits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home.
