2、College is a place to explore many possibilities; you really can’t do it all-unless you manage your time wisely. Here are some tips I have found very helpful for managing my time and maximizing(使…最大化) my study efforts： 1. Determine your goals. What do you want to get out of a college education? Academic(学术的) knowledge? Leadership experience within a club? Decide what is most important to you. Then devote proportionate(成比例的) amounts of time to those efforts. 2. Plan ahead. You may think you can keep everything in your head, but as the activities on your schedule start piling up, making a schedule can really help organize even little tasks. 3.Study at strategic (关键的) times. Don’t wait until you’re falling asleep to study. Study first. Save those e-mails to check later, because tasks that don’t require much energy and attention can still be done when you’re tired. 4.Motivate (激励) yourself! You know that TV show you’ve been dying to see, or that game of chess you’ve been waiting all week to challenge your friend to. These and many other special activities can be used for motivation. Promise yourself that you’ll force yourself to work efficiently. (Don’t rush through the assignment, though.) 5. Take a nap. Sometimes even a 20-minute nap in the afternoon will give you the extra energy you need to get through the day. 1. We need to play ahead in order to _ _ _ _ _ _ _ _ . A. keep a record of all the events B. better organize our activities C. store everything in our head D. pile up little tasks neatly 2. Strategic times are best for us to _ _ _ _ _ _ _ _ .
