18．Celebrating Sleep
World Sleep Day，observed on 21 March，was created to bring attention to the growing number of sleep problems worldwide．Sleep is a natural part of human life，but many people in the modern world ignore its importance．As a result，sleep problems are increasingly common．In 2002，scientists at the University of Athens in Greece conducted a survey of over 35，000people in 10countries around the world，including China，Belgium and South Africa．Of the people that responded to the survey，24percent said that they did not sleep well，and based on their responses，31.6percent were diagnosed with insomnia（失眠） and another 17.5percent were diagnosed with borderline（邊界線） insomnia．In addition，30.7percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6percent said that they felt very sleepy during the day．
Overall，the survey found that many people suffer the effects of poor quality sleep，some examples of which are being unable to fall asleep and waking up in the middle of the night．The main factors causing these problems are pressure from school or work and a fast pace of life，but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep．The survey's findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night．The short-term effects of this are tiredness and trouble concentrating．If this happens for a long time，the risk of gaining weight and having a heart attack may increase．
There are many things you can do to improve the quality of your sleep．First，you should have regular sleep habits．Try to go to bed and wake up around the same time each day．You also need to make your bedroom a cool，dark，quiet place to sleep so that heat，light and noise do not disturb you．At night，you should also avoid things that contain caffeine，such as chocolate，coffee，tea and many soft drinks，as caffeine may keep you from sleeping．
Getting a good night's sleep is important for everyone．By following the advice above，you can rest better at night and work better during the day．

2．Convincing people that your way is the best way is often very difficult---especially when you're not quite sure why they're saying no．Turn the tables on your conversation and convince people of your point of view．（36）D   And with the right methods，you can do it．
1．（37）BKnowing how to persuade people isn't just in words and body language-it's also in knowing the right time to talk to them．If you approach people when they are more relaxed and open to discussion，you will most likely achieve faster，better results．
2．Talk fast．People are more persuaded by a fast，confident talker than accuracy．Sort of makes sense-the faster you talk，the less time your listener has to process what you've said and question it．（38）E
3．Get to know them．A large part of whether or not persuasion is effective is based on the general understanding between you and your son/friend/employee．If you don't know the person well，it's necessary to start building this understanding immediately-find common ground as soon as possible．（39）GSo find parallels and make them known．
4．（40）AThere is something to be said for clarity．If you're confusing the person may want to agree with you，but doesn't necessarily know what you're looking for．Speaking in a firm way will help you maintain directness and keep your intentions clear．

A．Speak firmly．
B．Understand the best time．
C．Talk about what interests them．
D．The trick is to get them wondering why they're saying no．
E．Thus，you create the feeling that you truly grasp the subject．
F．If someone talks fast，it's the perfect time to persuade him．
