It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap（小睡）. When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications（药物治疗）may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.

In the United States, it is not customary to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p.m. If someone receives a call during sleeping hours, he assumes(想当然地认为)it's a matter of life and death. The time chosen for the call comm.unicates its importance.
In social life, time plays a very important part. In the U.S.A. guests tend to feel they are not highly regarded if the attention to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings arise(产生) between people from cultures that treat time differently. Promptness is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U.S. no one would think if keeping a business associate waiting for an hour. It would be too impolite. A person who is 5 minutes late is expected to make a short apology. If he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.
60. "The same meaning is attached to telephone calls after 11:00p.m." Here "attached" means _____.
A. taken B. drawn C. given D. shown
61. According to this passage, time plays an importantt role in _____.
A. everyday life B. school life
C. communication D. private life
62. The best title for this passage is _____.
A. The Voice of Time
B. The Importance of Time
C. The Importance of an Announcement
D. Time and Tide Wait for No Man
63. According to the passage, the author of the article may agree to which of the following statements?
A. It is appropriate to send your invitation cards three or four days before a dinner party date in U.S.A..
B. It may be appropriate to send your invitation cards to your guests three or four days before a dinner party date in some countries.
C. It is best for one to make telephone calls at eight because it costs much less.
D. If one is less than 5 minutes late, he has to make a short apology.

Wherever you went in the large hall, people were talking about the same thing. The PT/ Wireless and Networks Comm. China（中国国际通信设备技术博览会）held in Beijing last year was the biggest telecom exhibition in Asia．There were 400 representatives from 21 countries. But everyone was speaking the language of technology and there was only one word on their lips-3G.
Third-generation mobile phones, known as 3G, are the next big step for the telecom industry Data speeds in 3G networks are much quicker than present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.
“Mobile data is not a dream; it’s not an option—it’s a requirement,” said Len Lauer, head of US communications company Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday’s news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.
Face-to-face video calls
And don’t worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset.
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the UK Government awarded five licenses to run 3G wireless services, while the first 3G phones arrived in Italy four years later.
International telecom companies can’t wait to sell 3G in China, the world’s largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial phase before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch of the service,”said Fan Yunjun, marketing manager for Beijing Mobile.“We expect that the 3G licenses will be given out late next year.”
