UNIT 14. For you,these next four years will be a time unlike any other. Here you are surrounded by great resources: interesting students from all over the country, and student organizations covering every possible interest - from the arts to science , to community service and so on . You will learn to get by on very little sleep , meet fascinating people , and pursue new passions . I want to encourage you to make the most of this unique experience , and to use your energy and enthusiasm to reap the benefits of this opportunity.5. You may feel overwhelmed by the wealth of courses available to you . You will not be able to experience them all , but sample them widely ! College offers many things to do and to learn , and to learn , and each of them offers a different way to see the world . If I could give you only one piece of advice about selecting courses , it would be this : Challenge yourself ! Dont assume that you know in advance what fields will interest you the most . Take some coursers in fields youve never tried before . You will not only emerge as an unsuspected passion that will help to shape your future . A wonderful example of this is the fashion designer , Vera Wang , who originally studied art history . Over time , Wang paired her studies in art history with her love of fashion and turned it into a passion for design , made her a famous designer around the world.7. We have confidence that your journey toward self-discovery and your progress toward finding your own passion will yield more than personal advancement . We believe that as you become members of our community of scholars , you will soon come to recognize that with the abundant opportunities for self-enrichment provided by the university , there also come responsibilities . A wise man said：“Education is simply the soul of a society as it passes from one generation to anther.”You are the inheritors of the hard work of your families and the hard work of many countless others who came before you . They built and transmitted the knowledge you will need to succeed . Now it is your turn . What knowledge will you acquire ? What passion will you discover ? What will you do to build a strong and prosperous future for the generations that will come after you ?UNIT 36. For most undergraduates , non-stop Internet connectivity is the fuel of college life . More than just toys , these instruments are powerful tools for the storage and management of virtually every kind of information . And as more people around the world adopt these instruments , they are becoming indispensable . So , students should use the wonders of the Internet to do homework , review lecture outlines , take part in class discussions and network online with their friends . But in doing so , students must remember to regulate and balance their time . Too much time online can mean too little time in real-life studying or exercising or visiting with friends . Students should not let the Internet world outside.12. Colleges around the world have been replacing their computer systems for the past decade , in large part to provide students with the most advanced free system . The anywhere-anytime access has already yielded amazing benefits in education . With the widespread application of computer technologies , we are going to produce a generation of problem-solvers and intelligent thinkers , which is indispensable for the future of the world.UNIT 62. We have simplified and classified the data and the result are clear: The stakes are high . A heavy commitment to a part-time job during the academic year , say , working 20 hours per week or more , undermines and significantly interferes with school achievement and commitment . Overall , our study offers proof that student who worked more that 20 hours weekly were not comparable to their classmates . They earned lower grades , spent less time on homework , cut class more often , and cheated more frequently . And they reported lower levels of commitment to school and more modest educational aspirations.9. To summarize , convention has long held that early employment builds character . Our findings indicate that for many students , working 20 hours or more a week can contribute to decreased school performance and increased drug and alcohol use . We know that these findings may seem controversial to many . To our own surprise , our findings makes us question how long we have held on to the conventional assumptions about the great value of work in our formative years . Its time to abandon this appealing myth! We conclude that students should resolve to work no more than 10 hours per week if they want to be successful in school.
