Fighting racial stereotypes（模式化）on US campuses often begins by putting students of different ethnic backgrounds together — under one dormitory roof.

    Sam Boakye was a freshman at Ohio State University and the only black student on his floor. He was determined to get good grades — in part to make sure his white roommate had no basis for negative racial views. "You're pushed to do better, to challenge the stereotype that black people are not that smart," he told the New York Times.

    Several recent studies have found that having a roommate of a different race can reduce prejudice(偏见), diversify(使多样化) friendships and even promote students' academic performance. In a study by Ohio State psychology professor Russell Fazio, black freshmen who came to college with high test scores earned better grades if they had a white roommate—even if the roommate's test scores were low. Another study on student interaction by Duke University suggests that freshmen with roommates of a different race were the most likely to diversif“y their friendships. Just having diversity in classrooms doesn't do anything to increase interracial friendships," said Claudia Buchman, an author of the Duke study. “But living together with a different-race roommate does lead to more interracial friendships."

    There are, however, some problems with such room assignments. Fazio's study found that three times as many randomly(随机地) assigned interracial roommates weren't living together at the end of the semester, compared with white roommates. Interracial roommates also spent less time together, had fewer joint activities and were less involved with each other's friends than white pairs.

    As for Boakye, this is not the case. "A lot of white students come without much exposure（暴露）to diversity, so when their first interaction with a black guy isn't bad, they will make more black friends. I think I made a good impression on my freshman roommate. I saw him this year, and he said, "Hey dude, you're not the only black friend I have. That felt good."

    Jiajia, a third grader who was born with anemia, a medical condition in which there are too few red cells in blood, wrote an affecting article that moved many netizens.

    In the article, she shared her biggest wish: to survive so she could take care of her grandparents. Jiajia, 9, currently lives in the city of Suining in Sichuan province. In the article, she writes, "My heart gets heavier each time I see my grandma cry for me. If I ever get to grow up, I will take good care of her."

    Jiajia contracted pneumonia when she was 4 months old. Since then, she has required a blood transfusion every two weeks.

    After her parents' divorce, her grandparents took her in and faced many challenges in the process of raising her. The girl's article was only 235 words long, and it was handed in as a school assignment.

    Nevertheless, Jiajia's words "deeply impressed" her elementary school teacher, who then posted the article online, where it struck a chord with many people.

    Up till now, a fund started by teachers at Jiajia's school has reached more than 30,000 RMB, which will be put toward Jiajia's future blood transfusions.

Paris

Passengers carried per day: 4.4m

Cost of ticket: 80p flat fare

Length: 131 miles    Lines: 14   Stations: 297

    In Paris there are pleasures for those who use the Metro(地铁) — many of them artistic. The graceful Art Nouveau dragon-fly entrances are just the most noticeable on a Metro system which celebrated its 100^th anniversary by spending 30 million francs (£2.9million) on making its stations works of art. On my way home I pass Bonne Nouvelle station in the heart of Paris's cinema district. There, during the cinema festival this summer, special lighting effects dot the platforms and films are projected onto the large advertising boards.

    More than anything the metro is efficient. “When I worked on line 4”, says a retired driver, “we had exactly 30 minutes and 15 seconds to complete the journey. If it took any longer, they cut our pay.” But there are problems. Many Metro stations have too many stairs, and changing lines at big interchanges(交换) can be tiresome.

Moscow

Passengers carried per day: 9m

Cost of ticket: 12p

Length: 164 miles    Lines: 11   Stations: 162

    The first underground passage for the Moscow Metropolitan started in 1932. Three years later the trains started running. They haven't stopped since— every 90 seconds or two minutes during rush hour, every five minutes the rest of the time, from 6 a.m. till 1 a. m. There may be a crowd of people but there is seldom a wait.

    The trains take you through spacious and spotless stations. For tourists it's a major sightseeing attraction: from Russian Art Deco to neo-classical, the Metro stations are not to be missed.

Tokyo

Passengers carried per day: 7m

Cost of ticket: 90p ~ £1.68

Length: 177 miles    Lines: 12   Stations: 209

    Trains do not just arrive on time in Tokyo. They stop right on the platform mark so that passengers can line up knowing exactly where the doors will open. Train driving is a respectful job for life, for which the applicants must pass a strict screening of health checks, interviews and written exams before they can put on the enviable uniform, cap and white gloves.

    However, overcrowding means it is far from perfect. At rush hours, some stations employ part-time platform staff to push in passengers. Carriages can be filled to 184% of capacity(容量). The main reason for such conditions is that the Tokyo subway station system has only 15 miles of track for every 1 million people, compared to 36 on the London Underground. New lines are under construction, but at a cost of £500,000 per meter of rail. Progress has been slow.

Mexico City

Passengers carried per day: 4.2m

Cost of ticket: 11p flat fare

Length: 99 miles    Lines: 11   Stations: 175

    Fast, relatively safe, and very cheap, Mexico City's underground is an ideal place of order and efficiency compared to the disorders above. The Mexican capital's underground system is the biggest in the continent and one of the most subsidized (获得补助的) networks in the world.

    The first trains leave the station at 5 a.m. and the last after midnight as the crowd move from the outskirts of the 20 million-strong megacity (大城市). Mexico City's Metro also attracts a sizeable group of passengers who are unwilling to spend hours in traffic jams. There is a master plan to build new lines and extend existing one, but financial constraints (约束) complicated by the fact that the system runs through different jurisdicitons (管辖权) mean progress is slow.
