A. fewerB. muchC. less D. more
【A1】A.SEARCH, DON"T FILE.B.MAKE AN APPOINTMENT RIGHT AFTER WORK.C.FIGURE OUT YOUR CORE WORK ACTIVITIES.D.AVOID INSTANT MESSAGING AND TURN OFF PHONES.E.SAY NO. WHAT WOULD YOU DO IF YOU HAD AN EXTRA HOUR A DAY? THIS IS A COMMON BARRIER I RUN INTO WHEN I WRITE ABOUT MAKING POSITIVE LIFE CHANGES:PEOPLE DON"T HAVE TIME TO PURSUE THEIR DREAMS.PEOPLE DON"T HAVE TIME TO EXERCISE.PEOPLE DON"T HAVE TIME TO GET ORGANIZED.WELL, IT"S TIME TO MAKE TIME.BY USING SOME COMBINATION OF THE FOLLOWING, YOU CAN FREE UP AN HOUR OR MORE A DAY.FIND THE ONES THAT WORK FOR YOU (NOT ALL WILL WORK FOR EVERYONE), AND THEN CARVE OUT THAT HOUR A DAY.THEN MAKE SURE YOU USE THAT EXTRA HOUR A DAY IN THE BEST WAY POSSIBLE—BOOK THAT HOUR ON YOUR CALENDAR FOR SOMETHING YOU REALLY, REALLY WANT TO DO, WHETHER THAT"S WORK ON A GOAL, WRITE A BOOK, START A BUSINESS, EXERCISE, READ MORE, OR WHATEVER.DON"T SQUANDER THIS GIFT OF TIME! 【A1】______ WHETHER IT"S EXERCISE OR WORKING ON SOME OTHER GOAL, MAKE AN APPOINTMENT TO DO IT RIGHT WHEN YOU GET OUT OF WORK (AT 5 P.M., FOR EXAMPLE).THIS WORKS ESPECIALLY WELL IF YOU HAVE TO MEET SOMEONE ELSE, SUCH AS A WORKOUT PARTNER OR OTHER GROUP OR TEAM OR COACH OR PARTNER, YOU"LL BE SURE TO MEET THE APPOINTMENT, WHICH MEANS YOU WON"T STICK AROUND WORK TOO LONG, AND YOU"LL BE SURE TO FINISH ALL YOUR TASKS ON TIME SO YOU CAN LEAVE ON TIME.THIS MAKES YOU MORE EFFICIENT IN THE AFTERNOON ESPECIALLY. 【A2】______ I"M NOT SAYING THESE TYPES OF INSTANT COMMUNICATION DON"T HAVE THEIR USES, BUT IF THEY"RE ALWAYS ON AND YOU"RE ALWAYS AVAILABLE, YOU"RE ALWAYS AT THE MERCY OF OTHERS. IN-STEAD, JUST MAKE YOURSELF AVAILABLE AT SET TIMES IF NECESSARY, OR NOT AT ALL IF IT"S NOT NECESSARY.YOU DON"T HAVE TO TURN OFF PHONES ALL DAY LONG, BUT YOU SHOULD HAVE SOME UNBROKEN BLOCKS OF TIME WHEN YOU DON"T TAKE CALLS, SO YOU CAN CONCENTRATE ON YOUR IMPORTANT TASKS.THIS ALLOWS YOU TO GET MORE DONE IN LESS TIME, AS PHONE CALLS CAN EAT UP CHUNKS OF YOUR DAY IF YOU LET THEM. 【A3】______ I USED TO SPEND A LOT OF TIME FILING ALL MY COMPUTER FILES AND ALL MY EMAILS INTO NICE, ORGANIZED FOLDERS.I"D SPEND TIME EVERY DAY DOING THIS.NOW, I JUST ARCHIVE EVERYTHING, ON COMPUTER AND EMAIL, AND SEARCH WHEN I NEED SOMETHING.WITH QUICKSILVER ON THE MAC, EVERY FILE IS WITHIN A FEW KEYSTROKES.WITH GMAIL, EVERY EMAIL IS ACCESSIBLE INSTANTLY.NO TIME SPENT FILING! 【A4】______ WHAT IS IT THAT YOU REALLY HAVE TO DO EACH DAY? I MEAN, THE STUFF YOU HAVE TO DO OR YOUR JOB WOULD FALL APART IF YOU REALLY THINK ABOUT IT, A LOT OF THE TASKS YOU DO EACH DAY (AND PHONE CALLS AND EMAILS, MENTIONED ABOVE, ARE INCLUDED IN THESE TASKS) DON"T REALLY NEED TO BE DONE EACH DAY.SOMETIMES YOU CAN DO THEM LESS OFTEN, SOMETIMES YOU DON"T NEED TO DO THEM AT ALL.IF YOU CAN LEARN TO FOCUS ON YOUR CORE ACTIVITIES, YOU CAN GET YOUR WORK DONE IN LESS TIME. 【A5】______ ONE OF THE BIGGEST GROUPS OF TIME EATERS IS REQUESTS FROM OTHER PEOPLE.ALL DAY LONG WE GET REQUESTS, IN PERSON, ON THE PHONE, IN EMAIL, THROUGH PAPERWORK.MEETINGS, ASSIGNMENTS, REQUESTS FOR INFORMATION, REQUESTS TO BE ON A COMMITTEE OR TEAM...THESE ARE ALL REQUESTS THAT WILL EAT UP YOUR TIME.SAY NO TO ALL BUT THE ESSENTIALS.GET TO THE POINT. WHILE I"M A FAN OF LONG, SLOW CONVERSATIONS, IF YOU"RE TRYING TO MAKE TIME FOR GOALS, YOU NEED TO WHITTLE DOWN NEEDLESSLY LONG CONVERSATIONS—ESPECIALLY IF IT"S JUST WITH A COWORKER WHO ISN"T A CLOSE FRIEND.IN PERSON OR ON THE PHONE, YOU NEED TO GET STRAIGHT TO THE POINT WITH A MINIMUM OF CHIT-CHAT, AND IF THE OTHER PERSON ISN"T GETTING TO THE POINT, POLITELY ASK WHAT HE NEEDS FROM YOU.

共用题干 Sleep DeficitJudging from recent surveys,most experts in sleep behavior agree that there is virtually an epidemic（流行病）of sleepiness in the nation."I can't think of a single study that hasn't found Americans getting less sleep than they ought to,"says Dr.David.Even people who think they are sleeping enough would probably be better off with more rest.The beginning of our sleep-deficit（睡眠不足）crisis can be traced to the invention of the light bulb a century ago.From diary entries and other personal accounts from the 18th and 19th centuries,sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night."The best sleep habits once were forced on us,when we had nothing to do in the evening down on the farm,and it was dark."By the 1950s and 1960s,that sleep schedule had been reduced dramatically,to between 7.5 and 8 hours,and most people had to wake up to an alarm clock."People cheat on their sleep,and they don't even realize they're doing it,"says Dr.David."They think they're okay because they can get by on 6.5 hours, when they really need 7.5,8 or even more to feel ideally vigorous."Perhaps the most merciless robber of sleep,researchers say,is the complexity of the day.Whenever pressures from work,family,friends and community mount,many people consider sleep the least expensive item on his programme.In our society,you're considered dynamic if you say you only need 5;5 hours, sleep.If you've got to get 8.5 hours,people think you lack drive and ambition.To determine the consequences of sleep deficit,researchers have put subjects through a set of psycho-logical and performance tests requiring them,for instance,to add columns of numbers or recall a passage read to them only minutes earlier."We've found that if you're in sleep deficit,performance suffers,"says Dr.David."Short-term memory is weakened,as arc abilities to make decisions and to concentrate."People in the 18th and 19th centuries used to sleep about 9.5 hours a night because they had______.A:no drive and ambition B:the best sleep habitsC:no electric light D:nothing to do in the evening
共用题干 Are You Getting Enough Sleep?What happens if you don't get enough sleep? Randy Gardner,a high school student in the United States,wanted to find out. He designed an experiment on the effects of sleeplessness for a school science project. With doctors watching him carefully,Gardner stayed awake for 264 hours and 12 minutes.That's eleven days and nights without sleep!What effect did sleeplessness have on Gardner? After 24 hours without sleep,Gardner started havingtrouble reading and watching television. The words and pictures were too blurry（模糊）.By the third day,he was having trouble doing things withhis hands. By the fourth day, Gardner was hallucinating（产生幻觉）.For example,when he saw a street sign,he thought it was a person.He also imagined he was a famousfootball player. Over the next few days, Gardner's speech became so slurred（不清楚）that people couldn't understand him.He also had trouble remembering things.By the eleventh day, Gardner couldn't pass acounting test.In the middle of the test he simply stopped counting.He couldn't remember what hewas doing.When Gardner finally went to bed,he slept for 14 hours and 45 minutes.The second night he slept for twelve hours,the third night he slept for ten and one-half hours,and by the fourth night,he had returned tohis normal sleep schedule.Even though Gardner recovered quickly,scientists believe that going without sleep can be dangerous. They say that people should not repeat Randy's experiment. Tests on white rats have shown how serious sleeplessness can be. After a few weeks without sleep, the rats started losing their fur（皮毛）.And even though the rats ate more food than usual,they lost weight.Eventually the rats died.During your lifetime,you will probably spend 25 years or more sleeping.But why?What is the purpose of sleep? Surprisingly,scientists don't know for sure.Some scientists think we sleep in order to replenish（补充）brain cells. Other scientists think that sleep helps the body to grow and to relieve stress. Whatever the reason,we know that it is important to get enough sleep.During the experiment,Gardner slept for two hours every night.A:RightB:WrongC:Not mentioned
