Getting less sleep has become a bad habit for most American kids.According to a new survey by the National Sleep Foundation，51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights，even though they have to get up early.Last year the Foundation reported that nearly 60% of 7-to-12-year-olds said they felt tired during the day，and 15% said they had fallen asleep at school．
How much sleep you need depends a lot on your age.Babies need a lot of rest：most of them sleep about 18 hours a day!Adults need about eight hours.For most school-age children，ten hours is ideal（理想的）.But the new National Sleep Foundation survey found that 35% of 10-to-12-year-olds get only seven or eight hours.And guess what almost half of the surveyed kids said they do before bedtime？Watch TV.
"More children are going to bed with TVs on，and there are more opportunities to stay awake，with more homework，the Internet and the phone，" says Dr.Mary Carskadon，a sleep researcher at Brown University Medical School.She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep.Other experts say part of the problem is chemical.Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics，but also make it hard for teenagers to fall asleep before 11 pm.
Because sleepiness is such a problem for teenagers，some school districts have decided to start high school classes later than they used to.Three years ago，schools in Edina，Minnesota，changed the start time from 7：25 am to 8：30 am．Students，parents and teachers are pleased with the results.

1．Hi Judy!
You often complain to me that you always buy goods unreasonably on sale promotion（促銷）and feel it shameful after going back to your school dormitory with new things not needed，considering all the money you spend is your parents' income．
In fact，this is a common phenomenon，called impulsive buying，a buying unplanned and hard to control．It usually happens when a store offers discounts（打折）or sales promotion-a special way used by stores to get more customers，which means you may fall into its traps even without notice．
Stores，with a good knowledge of customers' psychology（心理），make use of it to drive business．Avoiding all the impulsive buying is a hard thing．However，knowing our psychology behind it and reducing the times when influenced by sales promotion may be useful．So you should keep calm when facing the sales promotion by keeping in mind what you really need．
Find out the conditions where you are likely to buy things blindly．When seeing a dress advertised at 20% off，do not concentrate on the discount，but warn yourself against falling into the trap of "saving money''．
Besides，do not forget the long-term effects of your choice when meeting a sales promotion．Short-term benefits，like excited feeling just after buying items encourage impulsive buying．But the long-term costs such as waste of money and the sense of shame really annoy you．When seeing the advertisements，remember what you really want to buy originally and warn yourself of that terrible feeling．Only in this way can you save money for really needed things．
Yours，
Rachel

3．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.

A．They do better in the real world.
