4．Conventional wisdom says that hardship can make us old before our time．In fact，a new study suggests that violence not only leaves long-term scars on children's bodies，but also changes their DNA，causing changes that are equal to seven to ten years of premature aging．
Scientists measured this by studying the ends of children's chromosomes（染色體），called telomeres，says Idan Shalev，lead author of a study published in Molecular Psychiatry．
Telomeres（端粒） are special DNA sequences （基因序列）which prevent the DNA in chromosomes from separating．They get shorter each time a cell divides，until a cell cannot divide any more and dies．
Several factors have been found to shorten telomeres，including smoking，radiation and psychological stresses such as being treated badly when young and taking care of a chronically（長期地） ill person．
In this study，researchers examined whether exposure to violence could make children's telomeres shorten faster than normal．They interviewed the mothers of 236 children at ages 5，7 and 10，asking whether the youngsters had been exposed to domestic violence between the mother and her partner； physical maltreatment by an adult； or bullying．Researchers measured the children's telomeres-in cells obtained by swabbing the insides of their cheeks-at ages 5 and 10．
Telomeres shortened faster in kids exposed to two or more types of violence，says Shalev．Unless that pattern changes，the study suggests，these kids could be expected to develop diseases of aging，such as heart attacks or memory loss，seven to 10 years earlier than their peers．
Shalev says there is hope for these kids．His study found that，in rare cases，telomeres can lengthen．Better nutrition，exercise and stress reduction are three things that may be able to lengthen telomeres，he says．
The study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes，says Charles Nelson，a professor of pediatrics and neuroscience at Harvard Medical School．

59．The new study found thatC．
A．hardship can change a child's aging
B．violence leaves scars on a child's mind
C．violence can speed up a child's aging
D．hardship has a long term effect on a child's mind
60．According to the text，telomeresB．
A．a(chǎn)re at the ends of people's chromosomes
B．can help prevent DNA from separating
C．can make a cell die quickly
D．become shorter before they die
61．Which of the following is TRUE according to the text？C
A．Violence can cause quick cell division in children's body．
B．Researchers measured the children's telomeres from their legs in the study．
C．Being treated badly will make a child's telomeres shorten faster．
D．Children who have shorter telomeres may have a heart attack earlier．
62．What is the best title for the text？A
A．Violence Aging Children's DNA
B．Children's Changing DNA Patterns
C．Violence and Telomeres
D．The Function of Telomeres．

1．Sometimes we can get so caught up in the stress and worry of our personal lives that our minds become too confused to operate effectively．This is especially dangerous in a test-taking situation．After hours of reading and studying，our brains can lock up in a state of overload．
In a stressful situation it's often a must to clear your mind completely to allow your brain to refresh itself and recalibrate all of its functions．But when you're tense，clearing your mind isn't so easy!Try this relaxation technique if you think your brain has seized up from information overload．
1．Set aside at least five minutes for quiet"clearing"time．If you're at school，see if you can put your head down somewhere or find an empty room or quiet space．If necessary，set a watch （or phone） alarm or ask a friend to tap you on the shoulder at a designated time．
2．Think of a time or place that puts you into a complete state of peace．This place will vary from person to person．Have you ever sat on the beach watching the waves come in and realized you've"zoned out"fora while？This is the sort of experience you're looking for．Other experiences that make us zone out could be：Sitting in the dark and staring at Christmas tree lights-remember how peaceful that feels？
3．Cover your eyes and go to your"place"．If you are at school preparing for a test before class，you may simply rest your elbows on the desk and put your hands over your eyes．For some people，it may not be a good idea to put your head down．（You might fall asleep!）
Don't let any thoughts creep into your head．As soon as you start to think about a test problem，clear away the thought and concentrate on your peaceful place．
4．Snap out of it!Remember，this is not nap time．The point here is to refresh your brain．After five or ten minutes of clearing time，take a brisk walk or take a drink of water to re-energize your mind and body．Stay relaxed and resist the urge to think about the things that are stressing you out or clogging your brain．Don't let your brain go back to freeze-out．
Now go on with your test or study session refreshed and ready!

2．Aerial（空中的）performer Jennifer Bricker was born without legs，but she never let it stop her．
Wrapped in a loop（圈）of red silk hung from the ceiling Jennifer Bricker climbs and twists to the music．Her head hangs down and her strong arms let go as she balances on her back，high above the ground a move-that's all the more daring because she has no legs．
Jennifer was a few months old when she was adopted by Sharon and Gerald Bricker．She had big brown eyes，a bright smile，and huge amounts of energy．When a doctor advised her adoptive parents to carry her around in a kind of bucket（桶），they refused．
Jennifer soon learned to walk-and run-on her hands and bottom，and grew up fearlessly climbing trees and bouncing on the trampoline （蹦床）with her three older brothers．"My parents didn't treat me differently so I didn't grasp the concept that I was different．I knew I didn't have legs but that wasn't stopping me from doing the things I wanted to do．"
At the age of three she was fitted with artificial legs，but she never really took to them-she moved more freely without．
In 1996 the Olympic Games took place in Atlanta．Jennifer loved to watch the women's gymnastics team，and especially adored the 14-year-old Dominique Moceanu who competed for the US．When Moceanu and the women's team won gold，Jennifer decided she was going to be a gymnast，too．She took up power tumbling，which involves performing floor exercises down a runway．But Jennifer did not want any allowances to be made for her disability．
At the age of 10 she took part in the Junior Olympics and by age 11 she was tumbling champion for the state of Illinois．
Jennifer now travels the world as an inspirational speaker and acts as an aerial performer．

21．What do we know about Jennifer Bricker？B
