I heard many parents cmplaining that their teenage children are rebelling. I wish it were s. At yur age yu ught t be grwing away frm yur parents. Yu shuld be learning t stand n yur wn feet. But take a gd lk at the present rebellin. It seems that teenagers are taking the same way f shwing that they disagree with their parents. Instead f striking ut bldly n their wn, mst f them are clutching at ne anther’s hands fr reassurance.
They claim they want t dress as they please. But they all wear the same clthes. Then set ff in new directins in music. But smehw they all end up with listening t the same recrd tgether. Their reasn fr thinking r acting in thus-and-such a way is that many peple are ding it. They have cme ut f their ccn int a larger ccn.
It has becme harder and harder fr a teenager t stand up against the ppularity wave and g his r her wn way. Industry has firmly carved ut a teenage market. These days every teenager can learn frm the advertisements what a teenager shuld have and be.
And many f tday’s parents have cme t award high marks fr the ppularity f their children. All this adds t a great barrier fr the teenager wh wants t find his r her wn path.
But the barrier is wrth climbing ver. The path is wrth fllwing. Yu may want t listen t classical music instead f ging t a party. Yu may want t cllect rcks when everyne else is cllecting recrds. Yu may have sme thughts that yu dn’t care t share with yur classmates at nce, well, g t it. Find yurself. Ppularity will cme with the peple wh respect yu fr wh yu are. That is the nly kind f ppularity that really cunts.

A．teenagers hw t learn t decide things fr themselves
B．readers hw t be ppular with peple arund
C．parents hw t cntrl and guide their children

C．dare nt cpe with prblems single-handedD．are much afraid f getting lst
42．What des the authr think f advertisements?

43．During the teenage years, ne shuld learn t______.
A．differ frm thers in as many ways as pssibleB．get int the right reasn and becme ppular

Hspital visits aren’t always easy, especially if yu’re nt sure what t d r say. 44 Befre yu head ff t see smene in the hspital, have a read thrugh the fllwing suggestins t ensure that yu’re all set fr a smth visit.
45 Even if there are visiting hurs prvided n the website, etc., the persn yu are wanting t see may nt be well enugh t see anyne at the time. If the patient’s dr is clsed, knck and wait fr permissin t enter. Yu can’t be sure whether r nt a medical prcedure is taking place r if the patient is sleeping.

Bring a gift card. Instead f flwers r candy, cnsider purchasing a gift card in the patient’s favrite stre. Certain patients usually can’t eat fr several days, s candy isn’t a very sensible gift. 47 They are usually a nuisance (麻烦事) when the patient is ready t g hme.
48 If there is any bad news frm hme r wrk, try yur best nt t tell it unless yu think that it is abslutely necessary. It is best fr the patient nt t be tld f bad news until they’re well enugh t cpe again. Assure the patient that he r she is missed at wrk, schl, r scial grups.

Are yu preparing fr a big test? If s, yu may want t play sme basketball in between hitting the bks. Dctrs are starting t find mre and mre infrmatin that suggests a cnnectin between exercise and brain develpment. Judy Camern, a scientist at Oregn Health and Oregn Health and Science University, studies brain develpment. Accrding t her research, it seems that exercise can make bld vessels(管), including thse in the brain, strnger and mre fully develped. Dr. Camern claims this allws peple wh exercise t cncentrate better. As she says, "While we already knw that exercise is gd fr the heart, exercise can really cause physical changes in the brain."
The effects f exercise n brain develpment can even be seen in babies. Babies wh d activities that require a lt f mvement and physical activity shw greater brain develpment than babies wh are less physically active. With babies, even a little mvement can shw big results. Margaret Barnes, a pediatrician(儿科医生), believes in the imprtance f exercise. She thinks that many learning disabilities that children have in elementary schl r high schl can be traced back t a lack f mvement as babies. "Babies need mvement that stimulates their five senses. They need t establish a cnnectin between mtin and memry. In this way, as they get lder, children will begin t assciate physical activity with higher learning," says Margaret.
Older peple can beef up their brains as well. Scientists frm 11 universities studied a grup f senirs ranging in age frm seventy t seventy-nine. Their study shwed a shrt-term memry increase f up t 40 percent after exercising just three hurs a week. The exercise des nt have t be very difficult, but it des have t increase the heart rate.
