Last month, she was facing expulsion (开除). Efforts to transfer to
3、the universitys forestry school had failed, and it looked as though the 26-year-old might have to return to China within a matter of weeks. In June, Han had been told that she was “not in good academic standing“ with her department an accusation she disputed. She had passed her qualifying exams at t
4、he first attempt and, after a few more tries, her required language exam as well. So she did something that many Chinese graduate students would never dream of doing: on 20 October she filed a complaint against Yale, accusing the university of treating Chinese students unfairly. The only Chinese stu
5、dent in her department, Han wrote in her complaint that she suspected professors were reluctant to work with her because they thought she would need extra help preparing manuscripts and grant proposals. Her grievance quickly gained a high profile on campus and beyond. Three other graduate students f
6、iled supporting testimonials that detailed problems they had experienced in their departments, and just over half of the 274 Chinese graduate students at Yale signed a statement backing her. The case was reported by media in the United States and even made the evening news in China. Within a week, u
7、niversity administrators relented and allowed Han to transfer to the department of forestry, where she had found an adviser willing to support her. Yale flatly denies any accusations of discrimination against Chinese students. Yale spokesman Tom Conroy said in a statement, “Yale has a long standing
8、tradition of being a welcoming and supportive university for international students, and especially those from China.“ Whether or not it was discrimination, Hans story taps into a rarely seen vein of discontent among Chinese students and postdocs (博士后) across the country. Chinese nationals are by fa
9、r the largest group of foreign academics working in US universities. Between 1985 and 2000, some 26,500 Chinese students earned science and engineering PhDs in the United States more than double the number of students from all of Western Europe, according to the National Science Foundation. And a re
10、cent survey of postdocs by scientific research society Sigma Xi in Research Triangle Park, North Carolina, showed that Chinese postdocs tend to work longer hours for less pay than their American counterparts. Language obstacles and culture shock Many Chinese come to the United States to participate
11、in cutting-edge research, but must first overcome language barriers, cultural differences. They frequently feel isolated from their US lab-mates. And although all graduate students are at the mercy of their advisers, foreign students are especially vulnerable. They lack alternative options, so a dis
12、agreement or funding problem is all that it takes for them to be sent back to China. The high percentage of Chinese in the lab is no coincidence. US researchers are happy to recruit academically gifted Chinese scholars, while the best and brightest Chinese are drawn to the country by research opport
13、unities that they cannot get at home. That opportunity is what brought Han from Inner Mongolia to Yale in 2003. She received her undergraduate and masters degree in ecology from Beijing Normal University, but had never travelled outside China. “Ecology research has only just started in China, so my
14、professors recommended that I study here,“ she recalls. She was ecstatic when she learned that Yale had admitted her to a PhD programme with funding from a Fan Family Fellowship, which supports Chinese students. But shortly after arriving in the United States, Han ran into difficulty. Like many Chin
15、ese students, she had studied English extensively in China, but that training focused primarily on reading and writing, not speaking. “The first semester was very hard,“ she says. “In physics and other departments, there are other Chinese graduate students who can help, but I was the only one in my
16、department.“ Hans experience is not unusual. Many Chinese students have trouble fitting in when they first reach the United States, according to Hongwen Zhu, a graduate student at the Albert Einstein College of Medicine in New York. Zhu says many students are embarrassed to admit that they dont unde
17、rstand what is being asked of them, or they are reluctant to raise their concerns vocally with their professors. “Most Chinese students tend to be very quiet, and this is a very big problem,“ he says. Han made steady progress in her language skills, but it came at a cost. She was unable to teach, a
18、requirement of her department, and she had trouble finding a research adviser. Still, Han was shocked to learn in June that she was no longer in good standing with her programme. On the edge of fellowship In the Hans case, Han could transfer to other department of Yale University, but she was inform
19、ed that she would lose the Fan Family Fellowship. Foreign students and postdocs frequently run into these sorts of funding problems, says Ji-Cheng Wang, a postdoc cancer researcher. Unlike American students, who can switch advisers if necessary, many foreigners are financially tied to their principa
20、l investigator (PI). “If anything happens to the PI then the student is put at risk,“ Wang says. This relationship can put students in a precarious position. When Wei Fu, not his real name, moved from Peking University to become a postdoc at a midwestern university, he was hoping for a chance to exp
21、and his own research career in biophysics. Instead, Fus lab director asked him to devote most of his time to existing experiments. “I didnt have much independence, I didnt feel free,“ he says. When Fu told the PI of his unhappiness, he found himself suddenly out of a job. He had just three months to
22、 scramble for a new position, or risk expulsion from the country. Eventually, he managed to find a position at a lab in California. “You can imagine that I was very stressed,“ he says. Visa obstacles That stress has been exacerbated (加重) by recent US and Chinese immigration policy. Most internationa
23、l students and scholars get a multiple-entry visa for the duration of their studies, but Chinese students must reapply for a new visa every six months. That is an improvement over the old rules, which required students to reapply each time they left the country, but it still causes trouble for resea
24、rchers such as Yangheng Zheng, a postdoc studying high-energy physics at the University of California, Los Angeles. While conducting graduate research at the University of Hawaii, Zheng frequently traveled between the United States and Japan, and each trip required a new visa both ways. “In three ye
25、ars I used up all of my passports pages,“ he says. Although the situation is better now, there are still problems, he says. Two months ago, on his latest excursion to CERN, the European particle-physics lab, he ended up stuck in Geneva for three weeks waiting for a US security check. Different views
26、 from Chinese students There is little consensus in the Chinese community over how serious these issues are. Some students and postdocs said they had not encountered significant problems, and many reported strong relationships with their advisers, who helped them resolve issues. “The people I know a
27、re very nice to me,“ says Ye Jin, a postdoc in molecular biology at the University of California, Berkeley. “When I try to write papers and proposals my PI has been very patient and corrects my grammar. She has been very encouraging.“ “Language is not a barrier if you are willing to learn,“ adds Gra
28、ce Wong, the president of Student Vision, a Boston-based group that helps students find jobs in biotechnology. “If your skills are good and youre willing to work really hard, any boss will love you.“ But Huang disagrees. “We really appreciate that the university gives us the chance to come here and
29、study,“ he says. “But even if you work hard, sometimes you still have the risk of being kicked out because of a funding problem or a disagreement with your adviser.“ （分数：71.00）(1).Xuemei Han failed to pass her qualifying exams and faced expulsion.（分数：7.10）A.YB.NC.NG(2).Xuemei Han was the only Chines
