Online learning is also called distance education. Many American colleges and universities have been offering it for years.One example is New York University in Manhattan. The School of Continuing and Professional Studies began online classes in nineteen ninety-two. Its Virtual College has taught more than ten thousand students from across the United States and other countries.Last year, the School of Continuing and Professional Studies launched NYU Online. It offers NYU's first online programs to earn a bachelor's degree. Programs are offered in three areas: leadership and management, information systems management and social sciences. University officials say classes are highly interactive, where students communicate with each other and their teachers. Some classes require students to all log in at the same time so they can attend live lectures by a professor. Students can also ask questions and work together on team projects. The university says classes are taught by NYU professors who have been trained in online teaching.International students must take two admission tests before they can be accepted into the program. These are the SAT and the TOEFL. We will discuss these tests later in our series.The cost to attend NYU Online depends on how many classes a student takes. It can cost as much as fifteen thousand dollars a year. NYU offers no financial aid for international students in this program. You can get more details at nyu.edu.1.

Passage TwoQuestions 26 to 30 are based on the following passage.Online learning is also called distance education, which helps students who take classes by computer over the Internet to learn certain courses and earn a degree. And it has become more and more popular with both young people and educational institutions.The School of Continuing and Professional Studies of New York University in Manhattan began online classes in 1992. Its Virtual School has taught more than 10,000 students from across the United States and other countries.Last year,the school launched NYU Online. It offers NYU's first online Programs for a bachelor's degree. Programs are offered in three areas; leadership And management, information systems management and social sciences. The classes are highly interactive where students communicate with each other and their teachers. Some classes require students to log in at the same time so they can attend live lectures by a professor Students can also ask questions and work together on team projects.The cost to attend NYU Online depends on how many classes a student is to take It costs as much as fifteen thousand dollars a year. NYU offers no financial aid for international students in this program. If you are interested in the program, you can gel more details at the website: www..nyu.edu. Many other schools, too, offer online education. Students should be especially careful of programs that offer a degree in return for little or no work. These are known as diploma mills, and are illegal in the United States.Educational advisers also say that before you enter any program, make sure the work will be recognized in your country. You should also make sure the schools you are considering are officially approved.26. The third paragraph is mainly about the __ of the programs of the School.A. academic goal and systemB. courses and learning modeC. learning methods and classesD. courses and requirements

Text 1 A new study suggests that contrary to most surveys,people are actually more stressed at home than at work.Researchers measured people’s cortisol,which is a stress marker,while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge.“Further contradicting conventional wisdom,we found that women as well as men have lower levels of stress at work than at home”,writes one of the researchers,Sarah Damske.In fact women even say they feel better at work,she notes.“It is men,not women,who report being happier at home than at work.”Another surprise is that findings hold true for both those with children and without,but more so for nonparents.This is why people who work outside the home have better health.What the study doesn’t measure is whether people are still doing work when they’re at home,whether it is household work or work brought home from the office.For many men,the end of the workday is a time to kick back.For women who stay home,they never get to leave the office.And for women who work outside the home,they often are playing catch-up-with-household tasks.With the blurring of roles,and the fact that the home front lags well behind the workplace in making adjustments for working women,it’s not surprising that women are more stressed at home.But it’s not just a gender thing.At work,people pretty much know what they’re supposed to be doing:working,making money,doing the tasks they have to do in order to draw an income.The bargain is very pure:Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.On the home front,however,people have no such clarity.Rare is the household in which the division of labor is so clinically and methodically laid out.There are a lot of tasks to be done,there are inadequate rewards for most of them.Your home colleagues—your family—have no clear rewards for their labor;they need to be talked into it,or if they’re teenagers,threatened with complete removal of all electronic devices.Plus,they’re your family.You cannot fire your family.You never really get to go home from home.So it’s not surprising that people are more stressed at home.Not only are the tasks apparently infinite,the co-workers are much harder to motivate.The blurring of working women's roles refers to the fact that____A.they are both bread winners and housewivesB.their home is also a place for kicking backC.there is often much housework left behindD.it is difficult for them to leave their office

共用题干Successful Language Learners1. Some people seem to have a knack for learning languages.They can pick up new vocabulary, master rules or grammar,and learn to write in the new language more quickly than others.They do not seem to be any more intelligent than others,so what makes language learning so much eas- ier for them?Perhaps if we take a close look at these successful language learners,we may dis- cover a few of the techniques which make language learning easier for them.2. First of all,successful language learners are independent learners.They do not depend on the book or the teacher;they discover their own way to learn the language.Instead of waiting for the teacher to explain,they try to find the patterns and the rules for themselves.They are good guess-ers who look for clues and form their own conclusions.When they guess wrong,they guess again. They try to learn from mistakes.3. Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language;they look for such a chance.They find people who speak the lan-guage and they ask these people to correct them when they make a mistake.They will try anything to communicate .They are not afraid to repeat what they hear or to say strange things;they are willing to make mistakes and try again .When communication is difficult,they can accept information that is inexact or incomplete.It is more important for them to learn to think in the language than to know the meaning of every word.4. Finally,successful language learners are learners with a purpose.They want to learn the language because they are interested in the language and the people who speak it.It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.5. What kind of language learner are you?If you are a successful language learner,you have probably been learning independently,actively,and purposefully. On the other hand,if your language learning has been less than successful,you might as well try some of the techniques outlined above. Paragraph 3______A: Ways to Learn a Language Successfully.B: Learning a language Purposefully.C: Learning a Language Actively.D: Learning a Language Independently.E: Learning from Mistakes.F: Learning to Think in the Target Language.

共用题干The Industrial Age and EmploymentThe industrial age has been the only period of human history in which most people's work has taken the form of jobs.The industrial age may now be coming to an end,and some of the changes in work patterns which it brought about may have to be reversed.This seems a daunting(大胆的)thought. But, in fact, it could offer the prospect of a better future for work.Universal employment,as its history shows,has not meant economic freedom.Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving(剥夺)them of the use of the land,and thus of the means to provide a living for themselves.Then the factory system destroyed the cottage industries and removed work from people's homes.Later,as transport improved, first by rail and then by road, people commuted(乘车往返)longer distances to their places of employment until,eventually,many people's work lost all connection with their home lives and the places in which they lived.Meanwhile,employment put women at a disadvantage.In pre-industrial times,men and women had shared the productive work of the household and village community.Now it became customary(惯例的)for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife.Tax and benefit regulations still assume this norm today,and restrict more flexible sharing of work roles between the sexes.It was not only women whose work status suffered.As employment became the dominant form of work,young people and old people were excluded-a problem now,asmore teenagers become frustrated at school and more retired people want to live active lives. All this may now have to change.The time has certainly come to switch some efforts and resources away from the utopian(乌托邦的)goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs. A.large number of teenagers will quit school next year.A:Right B:Wrong C:Not mentioned

问答题Oxford  When language learners arrive in Oxford, many ask where the university is, thinking that they will be shown just one building. It’s up to their teachers to explain that Oxford university is made up of a collection of many different colleges and institutions, each with its own history and characteristics.  There are many other surprises that learners discover about the city and its university. Katie Jennings is a social organizer at King’s St Joseph’s Hall in East Oxford, and it is her job to organize activities for learners outside of lesson time. She says many learners are surprised to discover that Oxford is a home to a wide variety of nationalities and ethnic groups, and one of the most popular social events is a night out at one of the town’s Latin American dance clubs. After a day spent learning English and absorbing the ancient atmosphere of the university, learners can samba the night away.  The city also has a thriving Asian community, and the sight of women in saris is as common in Oxford’s streets as academics in gowns and mortarboards. There is also a mouth-watering selection of Asian restaurants serving curries, as well as shops stocked with exotic vegetables and fruits.  The city has attracted such a diverse population not only because of the university, but also because it is an important industrial centre which is known for car manufacturing among other things. In spite of large industrial areas, the old of the city centre has remained surprisingly intact.  Carmel Engin, who teaches at the Lake School, says many learners are surprised to find that the city is free from the usual high-rise modern buildings. “From the centre of Oxford, you can see green hills in the distance, and this will make learners deeply feel that they are in a small, friendly town, but not just another modern metropolis.”  Some learners will be tempted to explore those green hills—Oxford is surrounded by some of the most beautiful countryside in southern England—but, as Engin admits, with so much to do and see in the city, few learners find the time, to explore its surroundings.

问答题Passage 1  In the 16th and 17th centuries, two persons helped lay the foundation of modern education. Comenius, a Czech humanist, greatly influenced both educational and psycho-educational thought. He wrote texts that were based on a developmental theory and in them introduced the use of visual aids in instruction. Media and instructional research, a vital part of contemporary educational psychology, has its origins in the writing and textbook design of Comenius. (1) He recommended that instruction start with the general and then move to the particular and that nothing in books be accepted unless checked by a demonstration to the senses. He taught that understanding, not memory, is the goal of instruction; that we learn best that which we have an opportunity to teach; and that parents have a role to play in the schooling of their children.  The contributions of one of our many ancestors often are overlooked, yet Juan Luis Vives wrote very much as a contemporary educational psychologist might in the first part of the 16th century. (2) He stated to teachers and others with educational responsibilities, such as those in government and commerce, that there should be an orderly presentation of the facts to be learned, and in this way he anticipated Herbart and 19th-centry psychologists. He noted that what is to be learned must be practiced, and in this way he anticipated Thorndike’s Law of Exercise. He wrote on practical knowledge and the need to engage student interest, anticipating Dewey. (3) He wrote about individual differences and about the need to adjust instruction for all students, and anticipated the work of educational and school psychologists in the area of special education. He discussed the school’s role in moral growth, anticipating the work of Dewey, Piaget, Kohlberg, and Gilligan. He wrote about learning being dependent on self-activity, a precursor to contemporary research on meta-cognition, where the ways in which the self monitors its own activities are studied. Finally, (4) Vives anticipated both the contemporary motivational theorists who avoid social comparisons and those researchers who find the harmful elements of norm-referenced testing to outweigh their advantages, by writing about the need for students to be evaluated on the basis of their own past accomplishments and not in comparison with other students. (5) Thus, long before we claimed our professional identity, there were individuals thinking intelligently about what we would eventually Call educational psychology, preparing the way for the scientific study of education.

问答题Practice 4  Read the following text(s) and write an essay to  1) summarize the main points of the text(s),  2) make clear your own viewpoint, and  3) justify your stand.  In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks (“ ”).  You should write 160—200 words on the ANSWER SHEET.  The information and computer technologies have boosted the efficiency and convenience of people’s work and study. Their application in school education has provided teachers and students with new approaches to knowledge and information. There is a heated discussion about whether computers will replace teachers. The following are the supporters’ and opponents’ opinions.  Supporters:  With the advanced computer and Internet, children can get the learning material whenever they want.  Online teaching is becoming more and more popular that students can get planned lessons online. After each class, there is homework for them to do. Both the learning and practice can be done on computers.  From computers students can learn something that they are interested in so that they won’t be restricted to the subjects that they are taught at school. Therefore, students will have the opportunity to achieve an all-around development.  Opponents:  Students need to communicate with teachers and get instructions from them whenever they have troubles in their study. Computers are only cold devices that will affect children’s ability to have face-to-face communication.  Education is not only about imparting the knowledge, but also being a useful person. So students need to learn some useful values to be a good person which sometimes cannot be easily learned from computers.  Children who use computer will learn to communicate with machines instead of people. There is a risk that they will be a generation of social illiterates.
