試題詳情
Heads up!Across the country，sports injuries are a safety concern for young athletes.Now，the American Medical Association （AMA） has a new set of guidelines aimed at protecting players from the danger of concussions-serious injuries caused by a blow to the head.
"By raising awareness of the serious risks associated with concussions and ensuring that the appropriate guidelines are in place，we can reduce the number of young athletes who may return to the game too soon，which can put their health at further risk，" said AMA Board Member Jack Resneck Jr.，M.D.，in a statement.
The policy recommends that young athletes who may have a concussion be taken off the field as soon as possible.Then，they are only to return to their sport with a doctor's written approval.The policy also sets age-specific rules for health care professionals and athletic organizations in evaluating and caring for athletes who have concussions.
According to the Centers for Disease Control and Prevention（CDC），a concussion is a type of traumatic（創(chuàng)傷的） brain injury caused by a bump，blow，or jolt to the head or hit to the body that causes the head and brain to move rapidly back and forth.This type of movement can cause the brain to bounce around or twist inside the skull （顱骨）.It can damage brain cells and create chemical changes in the brain.
The CDC says that between 1.6 million and 3.8 million traumatic brain injuries caused by sports and recreation-related activities occur in the U.S.jye.ai year.A study from the Center for Injury Research and Policy showed that as many as 40% of high school athletes return to playing before they should.The AMA's new guidelines should help to bring those numbers down.

1．Hi Judy!
You often complain to me that you always buy goods unreasonably on sale promotion（促銷(xiāo)）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.
