Competition between international universities is heating up, as China grows as one of the largest exporters of students aiming to study abroad. “Lots of universities are becoming more and more aggressive to attract Chinese students. Every day I receive contacts from universities in the US expressing the desire to come to China to recruit students,” said Frank Joseph, a commercial officer from embassy of the United States.

One key reason why more Chinese students are able to study abroad is the economy: With China’s boom within the past decade, more families have the financial wherewithal (资金) to send their children to international universities. There will be a total of 200,000 family-funded Chinese students studying overseas in 2011, up 20 percent from last year, said Wu Zaofeng, deputy secretary general of China Education Association for International Exchange.

International institutions, Joseph said, are also facing increasingly tough financial situation with a shortage of domestic students and a drop in government subsidies (补贴). Students, especially in the US are paying high tuition fees and living expenses. Chinese students with money to spend, according to experts, can fill up the gap. Students on average spend 150,000 yuan to 200,000 yuan every year studying in US, according to statistics from the US Institute of International Education. During 2009-2010, there were approximately 81,000 Chinese students studying in the US, up 19.8 percent from 2008.

Representatives from approximately 60 universities from the United States are planning to arrive in Beijing this weekend to attract more Chinese students at this year’s fair. Besides the US, many other countries are also vying (竞争) to enroll Chinese students.

Post-study work visa put out by British government allows all international students completing a UK degree qualification to apply for a visa to stay on and look for work in UK for up to 2 years. Being the third most popular destination for international students next to the US and the UK, France has set up two types of scholarships and has handed out an increase of 26 percent in scholarship funds to Chinese students in recent years.

C．that the students in China are becoming richer and richer

D．that the students in foreign countries do not want to go to universities小题2: Why are more Chinese students able to study abroad?

如图（甲）所示为电视机中显像管的原理示意图，电子枪中的灯丝加热阴极而逸出电子，这些电子再经加速电场加速后，从O点进入偏转磁场中，经过偏转磁场后打到荧光屏MN上，使荧光屏发出荧光形成图象，不计逸出电子的初速度和重力．已知电子的质量为m、电荷量为e，加速电场的电压为U，偏转线圈产生的磁场分布在边长为l的正方形abcd区域内，磁场方向垂直纸面，且磁感应强度随时间的变化规律如图乙所示．在每个周期内磁感应强度都是从-B₀均匀变化到B₀．磁场区域的左边界的中点与O点重合，ab边与OO′平行，右边界bc与荧光屏之间的距离为s．由于磁场区域较小，且电子运动的速度很大，所以在每个电子通过磁场区域的过程中，可认为磁感应强度不变，即为匀强磁场，不计电子之间的相互作用．

（1）求电子射出加速电场时的速度大小

（2）为使所有的电子都能从磁场的bc边射出，求偏转线圈产生磁场的磁感应强度的最大值B₀

（3）荧光屏上亮线的最大长度是多少．
