《复变函数》练习题一练习题第一套一、填空题1．设x 、y 为实数，称形如（x ,y ）的 有序数对 为复数。
2．设z =x +iy ，则称z e = )sin (cos y i y e x + 为指数函数，其中“e ”为自然对数的底。
3．若存在某个N (a ,δ)，使得 f (z )在N (a ,δ)内处处可导 ，则称点a 为函数f (z )的解析点。
4．将函数zz f -=11)(在点z =1展成罗朗级数，即在 0<|z -1|<+∞ 内展成罗朗级数。

儿童文学练习题
《儿童文学》练习题第一套（练习题）一、名词解释：1、儿童情趣：2、儿童文学题材：二、问答题：1、什么是儿童文学？2、从柯岩的儿童诗《坐火车》，分析儿童文学的最大特征是什么？(《坐火车》见《儿童文学作品选读》)我们先来看作品《坐火车》：小板凳，摆一排，／小朋友们坐上来，／我们的火车跑得快，／我当司机把车开。
／(轰隆隆隆，轰隆隆隆，呜!呜!)抱娃娃的靠窗坐，／牵小熊的往后挪，／皮球积木都摆好，／大家坐稳就开车。
／(轰隆隆隆，轰隆隆隆，呜!呜!)（以上引用的是《坐火车》的前两节，全诗共四节，采用同样的表现形式。
）三、分析题：1、儿童文学可以描写爱情题材吗?举例说明。
第一套（答案）一、名词解释：1、指与儿童心理特点相适应的儿童语言、行为的情调趣味。
2、指儿童文学作品中具体描绘的社会生活事件或现象，是作品内容的最主要因素。
二、问答题：1、(1)儿童文学是指为少年儿童所理解、所喜爱，有利于他们身心健康发展的各类文学作品的总称。
(2)儿童文学是文学作品中最富有儿童情趣的那一部分。
(3)儿童文学包括婴幼儿文学、童年文学、少年文学三大层次。
2、仅此两节，即使没有一点儿童文学理论知识的人，也会凭感觉认为这是一首儿童诗，原因就在于诗中富有浓厚的儿童情趣，表现出一种与成人文学所完全不同的文学特征。
所谓儿童情趣，就是作品中所反映出的儿童特有的情调与趣味。
如诗中摆起小板凳做火车、“我当司机”以及模仿车轮的轰隆声和汽笛的呜叫，都是与儿童心理相适应的儿童特有的(不属于成人的)行为与语言。
第二节更富童趣。
“抱娃娃的靠窗坐”，仿佛真在车上；“牵小熊的往后挪”，看，车上秩序井然；“皮球积木都摆好”，对孩子来说，玩具总是少不了的，走到哪儿带到哪儿；“大家坐稳就开车”，俨然一副火车司机的口气，又自然地引向下一节。
而这一切情景都是孩子式幻想的产物。
游戏、幻想、纯情、欢快，这些由儿童特有的行为与语言造成的童趣美与稚拙美，就是典型的儿童情趣。

When next year's crop of high-school graduates arrive at Oxford University in the fall of 2009, they'll be joined by a new face; Andrew Hamilton, the 55-year-old provost (教务长) of Yale, who'll become Oxford's vice-chancellor-a position equivalent to university president in America.Hamilton isn't the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc, have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it's gone global. Yet the talent flow isn't universal. High-level personnel tend to head in only one direction: outward from America.The chief reason is that American schools don't tend to seriously consider looking abroad. For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university's budget. "We didn't do any global consideration," says Patricia Hayes, the board's chair. The board ultimately picked Bruce Benson, a 69-year-old Colorado businessman and political activist (活动家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a distinctively American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity. Many European universities, meanwhile, are still mostly dependent on government funding. But government support has failed to keep pace with rising student number. The decline in government support has made funding-raising an increasing necessary ability among administrators and has hiring committees hungry for Americans.In the past few years, prominent schools around the world have joined the trend. In 2003, when Cambridge University appointed Alison Richard, another former Yale provost, as its vice-chancellor, theuniversity publicly stressed that in her previous job she had overseen "a major strengthening of Yale's financial position."Of course, fund-raising isn't the only skill outsiders offer. The globalization of education means more universities will be seeking heads with international experience of some kind of promote international programs and attract a global student body. Foreigners can offer a fresh perspective on established practices.16. What is the current trend in higher education discussed in the passage?A. institutions worldwide are hiring administrators from the U.S.B. A lot of political activists are being recruited as administrators.C. American universities are enrolling more international students.D. University presidents are paying more attention to funding-raising.17. What is the chief consideration of American universities when hiring top-level administrators?A. The political correctness.B. Their ability to raise funds.C. Their fame in academic circles.D. Their administrative experience.18. What do we learn about European universities from the passage?A. The tuitions they charge have been rising considerably.B. Their operation is under strict government supervision.C. They are strengthening their position by globalization.D. Most of their revenues come from the government.19. Cambridge University appointed Alison Richard as its vice-chancellor chiefly because _____.A. she was known to be good at raising moneyB. she could help strengthen its ties with YaleC. she knew how to attract students overseasD. she had boosted Yale's academic status20. In what way do top-level administrators from abroad contribute to university development?A. They can enhance the university's image.B. They will bring with them more international faculty.C. They will view a lot of things from a new perspective.D. They can set up new academic disciplines.Unit 11Choose a word that best completes each of the following sentences.1. The door was open.It______ open. I had locked it myself and the key was in my pocket.A. can’t beB. mustn’t beC. can’t have beenD. mustn’t have been2. -----I bought this shirt for 35 yuan yesterday.-----It’s on sale today for only 30.
