What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in apart-time job. Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

The whole passage centers on__________.

Learning Disabilities
Learning disabilities are very common.They affect perhaps 1 0 percent of all children.Four times as many boys as girls have learning disabilities.
Since about 1970,new research has helped brain scientists understand these problems better.Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things.There is no longer any question that all learning disabilities result from differences in the way the brain is organized.
You cannot look at a child and tell if he or she has a learning disability.There is no outward sign of the disorder.So some researchers began looking at the brain itself to learn what might be wrong.
In one study,researchers examined the brain of a learning-disabled person who had died in an accident. They found two unusual things.One involved cells in the left side of the brain,which control language.These cells normally are white.In the learning disabled person,however,these cells were gray.The researchers also found that many of the nerve cells were not in a line the way they should have been.The nerve cells were mixed together.
The study was carried out under the guidance of Norman Geschwind,an early expert on learning disabilities, Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He believed this side of the brain failed to develop normally.Probably,he said,nerve cells there did not connect as they should.So the brain was like an electrical device in which the wires were crossed.
Other researchers did not examine brain tissue.Instead,they measured the brain's electrical activity and made a map of the electrical signals.
Frank Dully experimented with this technique at Children's Hospital Medical Center in Boston.Doctor Dully found large differences in the brain activity of normal children and those with reading problems.The differences appeared throughout the brain.Doctor Dully said his research is evidence that disabilities involve damage to a wide area of the brain,not just the left side.

Which of the following is NOT mentioned in the passage?
A:Learning disabilities may result from the unknown area of the brain.
B:Learning disabilities may result from damage to a wide area of the brain.
C:Learning disabilities may result from abnormal organization of the brain cells.
D:Learning disabilities may result from problems in the left side of the brain.

An increase in students applying to study, economics at university is being attributed to the global economic crisis awakening a public thirst for knowledge about how the financial system works.
Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.
Professor John Beath, the president of the society and a leading lecture at St Andrews University, said his first-year lectures which are open to students from all departments--were drawing crowds of 400, rather than the usual 250.
"There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to ~'elate my teaching to contemporary events in a way that one hasn't traditionally done. " He added.
University applications rose 7% last year. But there were rises above average in several subjects. Nursing saw a 15%,jump, with people's renewed interest in caters in the pubic sector, which are seen as more secure in economic crisis.
A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.
Zack Hocking, the head of Child Trust Funds, said: "It's possible that one good thing to arise from the downturn will be a generation that's financially wiser and better equipped to manage their money through times of economic uncertainty."
According to Hocking, the global economic crisis might make the youngsters__________.

A. wiser in money management
B. have access to better equipment
C. confide about their future careers
D. get jobs in Child Trust Funds

Exercise and Brain

Just as exercise strengthens the heart and lungs,bones and muscles,it may also power up the brain.A succession of scientific studies of animals implies that physical activity has a positive effect on mental functioning.
"It's clear that the brain benefits from exercise,"says brain scientist William Greenough of the University of Illinois at Urbana-Champaign.His studies with rats have demonstrated two primary effects of activity:Vigorous physical exercise provides the brain with more fuel,and skill-based ex-ercise increases the formation of connections in the brain, which, according to the proposals of some scientists,may make the brain better able to process information.
In one experiment,laboratory rats were separated into three groups.One group was exercised by running inside an automatic wheel,a second group improved their skills in a complicated obstacle course,and a third group was inactive.
"The animals that learned to go through the obstacle course exhibited a greater number of brain connections than the animals in the exercised or inactive groups,"Greenough said."In contrast, the animals that exercised inside the automatic wheel possessed a greater density of blood vessels in the brain than did either of the other two groups of animals."
Learning a new dance step may boost the brain in the same way that learning a language can, he says.And if the dance is a good physical exercise as well,the benefits multiply.Young brains may be especially able to boost brain power through exercise,suggested another of Greenough's experiments that showed the most significant changes in the brain occurred among rats that had been exercised when very young.And while animals aren't people,he says it is logical to make the inference that an effect found in rats may also apply to humans.
Human studies have focused primarily on older adults and suggest that regular exercise can improve the speed with which the brain processes information.Measurements made by Arthur Kramer at the University of Illinois demonstrated that inactive adults,aged 63 to 82,could hit buttons faster in response to a tone after they went through a 10-week water exercise course.A corresponding control group that didn't exercise showed no improvement.

According to the passage what is not the advantage of physical exercises?
A:do good to our mental health.
B:strengthen our hearts and lungs.
C:strengthen our bones and muscles.
D:help us lose weight.

If you want to stay young,sit down and have a good think．This is the research result of professor Faulkner,who says that most of our brains are not getting enough exercise and as a result,we are ageing unnecessarily soon.
Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losing their ability to think and to reason at a relatively early age,and how the process of ageing could be slowed down.
He set about measuring brain volumes of a thousand people of different ages and occupations．
Computer technology enabled him to obtain precise measurements of the volume of the front and side sections of the brain,which relate to intelligence and emotion,and determine the human character．
Contraction of front and side parts--as cells die off--was observed in some subjects in their thirties,but it was still not evident in some sixty-and seventy-year-olds.
Faulkner concluded from his tests that there is a simple way to slow the contraction—using the head.
The findings show that contraction of the brain begins sooner in people in the country than in the towns．Those least at risk,says Faulkner,are lawyers,followed by university professors and doctors．White--collar workers doing routine work are,however,as likely to have shrinking brains as the farm worker,bus driver and shop assistant.
Faulkner's findings show that thinking can prevent the brain from shrinking．Blood must circulate properly in the head to supply the fresh oxygen the brain cells need．"The best way to maintain good blood circulation is through using the brain,"he says．"Think hard and engage in conversation．Don't rely on pocket calculators."

The professor's tests show that__.

A.our brains shrink as we grow old
B.the front section of the brain does not shrink
C.seventy-year-olds have better brains than sixty-year-olds
D.brain contraction may vary among people of the same age

资料：Did your child's brain shrink last summer? Probably not, but it may have shifted into reverse, according to a study by Dr. Harris Cooper, professor of psychology at the University of Missouri-Columbia. The study found that when students return to school after a long summer vacation, they've lost one to three months worth of learning.
The decline is more detrimental for math than it is for reading. "All students lose math skills," says Cooper. It may be because community and home environments give kids more opportunities to practice reading than math. The study also found that income has an impact on how much a student loses or gains in reading. Middle-class children actually gained in reading over the summer, while lower-income students experienced losses. Cooper attributes this to the enrichment activities that many middle-class kids participate in over the summer, such as camp and trips.
Your kids don't have to spend the summer stuck in reverse. "Parents can help their kids retain educational skills," says Cooper. He suggests the following five tips to kick off a learning-filled summer.
1. Keep lots of books around and make regular trips to the library. Most libraries schedule special summer events for kids. Sign up your family!
2. Think about what your kids may be learning next year when you plan the family vacation. Talk with teachers to find out what they'll be covering in class. If it's a unit on the civil war for example, you may want to schedule a visit to Gettysburg. If it's geology, visit a national park.
3. Keep math in mind. Since kids lose more math skills than anything else over the summer, try to do some special planning to find math-related activities. For example, if you can't decide whether to sign your child up for "Shakespeare's Theater" or "Math Magic" at the local community center, go with the math.
4. Consider summer school or tutoring. Struggling kids can get a lot of different kinds of help from these programs. Summer school can also enrich and accelerate learning in areas where kids show a special interest.
5. Call the curriculum coordinator in your child's school district, visit the school board office, or contact the schools of education at local colleges and universities to find out what educational programs will be offered in your area over the summer.
Remember to keep it fun! You don't want to sour your kids on learning during the summer break.

How dose income affect a student’s loses or gains in summer learning? （ ）

A.Lower-income children experienced lose in math over the summer
B.Middle-class children gained in learning over the summer
C.Lower-income children gained in math over the summer
D.Middle-class children suffered lose in math over the summer

High Stress May Damage Memory

According to a report issued in May 1998,elderly people who have consistently high
blood levels of cortisol (皮质醇）don't score as well on memory tests as their peers with
lower levels of the stress hormone. What's more,high levels of cortisol are also associated
with shrinking of the hippocampus（海马区）,a region of the brain that plays a key role in
learning and memory.
The findings suggest that even cortisol levels in the normal,"healthy"range can
actually accelerate brain aging.
The study results"now provide substantial evidence that long-term exposure to adrenal
(肾上腺的）stress hormones may promote hippocampal aging in normal elderly humans",
write Nada Porter and Philip Landfield.Cortisol is a hormone released in response to stress
by the adrenal glands（腺）,which sit on top of the kidneys(肾）.
Over a 5-to 6-year period,Dr. Sonia Lupien and his colleagues measured 24-hour
cortisol levels in 51 healthy volunteers,most of whom were in their 70s.
The researchers tested the volunteers' memory on six people in the increasing/high
category and five people in the decreasing/moderate group.The groups did not differ in
tests of immediate memory,but the increasing/high cortisol group had other memory
problems compared with those in the decreasing/moderate group.
The researchers also found that the total volume of the hippocampus in those in the
increasing/high group was 14% lower than those in the decreasing/moderate group,
although there were no differences in other brain regions.
The results suggest that“…brain aging can be accelerated by levels of adrenal
hormones that are not generally regarded as pathological（病态的）and that variation within
this normal range is related to variation in the rate of brain aging",write Porter and
Landfield."This further suggests that chronic stress may accelerate the worsening of the
hippocampus."

When the levels of cortisol go high,the hippocampus
A:may expand.
B:may shrink.
C:may disappear.
D:may function better.

Yoga May Help Ease High Blood Pressure

People who follow the ancient practice of yoga may be getting an added health boost,with a new study suggesting it can fight high blood pressure一also known as hypertension.
"This study confirms many people's feelings that exercise may be useful in the control of hypertension,"said Dr. Howard."Yoga would be a useful adjunct in the lowering of blood pressure in certain populations."
_________(46)Although the study couldn't prove a cause-and-effect relationship,doing yoga two to three times a week was associated with an average drop in blood pressure readings from 133/ 80 to 130/77,the researchers said.
In comparison,the average decrease in blood pressure was smaller(134/83 to 132/82)among people who ate a special diet but did not do yoga.
In a bit of a surprise,doing yoga in tandem with a special diet did not outperform doing yoga alone.___________(47)
Dr. Howard said the study shows that"yoga can have a favorable effect" on hypertension. ________(48)"But some large population studies have suggested that changes of this magnitude could have very significant long-term benefits."
___________(49)including its relatively short length and the fact that most participants were young and had milder forms of high blood pressure,Dr. Howard said.
__________(50)"Yoga,along with deep breathing exercises,meditation and inner reflection,is a good adjunctive and integrative cardiovascular approach to better health,including lowering blood pressure,as this data suggests,"said Dr. David Friedman.

__________(46)
A:The amount of change was small,he said.
B:Another expert agreed that the ancient Indian practice of yoga might ease hypertension.
C:In the study,researchers tracked 58 women and men,aged 38 to 62,for six months.
D:Yoga is proved to be effective in lowering high blood pressure.
E:The study did have some limitations.
F: This may be because doing both required a greater amount of time,making it more difficult for participants to stick with their regimens.

—Did you have any problems in your English study
