As high school students, Sang Tian and Huang Yunru dreamed of attending one of the world’s top universities. They slaved over their studies and were in the end admitted to famous schools – only one turned out to be far more famous than the other, according to new ranking (排名)of Asia’s top schools.

Huang Yunru, 19, went to the University of Hong Kong, the No 1 school in Asia. Sang, also 19, went to Tsinghua University, which was ranked a disappointing 16th in Asia. When Sang heard the news, he couldn’t believe his ears. “What? How can it be?” he said, greatly surprised.

The new list of Asia’s top 200 universities was published last month by Quacquarelli Symonds (QS), a UK-based career and education company. The ranking have started heated discussions among Chinese people, since the mainland’s top two schools – Peking University (PKU) and Tsinghua University – were not in the top 10.

Actually, this isn’t the first time that the schools have gone on poorly in regional or global ranking. The 2010 world university list released by the magazine US News & World Report ranked Peking University at 50th and Tsinghua University at 56th. They were the only two mainland schools in the top 100. Meanwhile, 37 US universities made the top 100 list. And three of 10 Hong Kong universities made the top 50.Chinese universities’ poor performance has saddened many students. “I can’t understand their standards,” said Sang. “At least we are a university with a long, proud history.”

According to the QS list, Chinese universities are doing OK in academic peer review, with both Tsinghua and Peking University scoring a full 100. But when it comes to student-to-faculty ratio（师生比）, their ranking drops, with Tsinghua at 22th and Peking at 23rd.John Hennessy, president of Stanford University, said at the Fourth Chinese-Foreign University Presidents Forum in early May that a lack of small-group discussions has seriously affected the teaching quality at Chinese universities. This has also resulted in students being afraid to question or challenge teachers.

小题1:Peking University (PKU) and Tsinghua University were in the top 10 in the ranking of Asia’s top schools.

小题2:There were no top 100 universities in the mainland according to the ranking.

小题3:Hong Kong universities are doing much better than the Chinese mainland ones in the ranking.

小题4:Peking University (PKU) and Tsinghua University are so famous that they are not worried about the result at all.

小题5: One of the reasons for the mainland’s universities’ disappointing ranking is that there are simply not enough teachers for the large number of students.

（5）------中偏易题

When other nine-year-old kids were playing games, she was working at a petrol station．When other teens were studying or going out, she struggled to find a place to sleep on the street．But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University．And her amazing story has inspired a movie, “Homeless to Harvard: The Liz Murray Story”, shown in late April.

Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination．Liz grew up in the shadow of two drug-addicted parents．There was never enough food or warm clothes in the house．Liz was the only member of the family who had a job．Her mother had AIDS and died when Liz was just 15 years old．The effect of that loss became a turning point in her life．Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

Liz went back to school．She threw herself into her studies, never telling her teachers that she was homeless．At night, she lived on the streets．“What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being．I had only experienced a small part of the society,” she wrote in her book Breaking Night.

She admitted that she used envy to drive herself on．She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”．She finished high school in just two years and won a full scholarship to study at Harvard University．But Liz decided to leave her top university for a couple of months earlier this year in order to take care of her father, who has also developed AIDS．“I love my parents so much．They are drug addicts．But I never forget that they love me all the time.”
