Young Adults Who Exercise Get Higher IQ Scores
Young adults who are fit have a higher IQ and are more likely to go on to university,reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS)The study involved 1 .2 million Swedish men doing military service who were born be-tween 1950 and 1976 .The research group analyzed the results of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link between good physical fitness and better results for the IQ test. The strongest links are for logical thinking and verbal comprehension.But it is only fitness that plays a role in the results for the IQ test,and not strength.“Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen,”says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. “This may be one of the reasons why we can see a clear link with fitness,but not with muscular strength .We are also seeing that there are growth factors that are important.”
By analyzing data for twins,the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and higher IQ.
“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Maria Aberg,researcher at the Sahl-grenska Academy and physician at Aby health centre.“This being the case,physical education is a subject that has an important place in schools,and is an absolute must if we want to do well in maths and other theoretical subjects.”
The researchers have also compared the results from fitness tests during national service with the socio-economic status of the men later in life.Those who were fit at 18 were more likely to go into higher education,and many secured more qualified jobs.

The study findings include the following EXCEPT that_______.
A: growth factors are significant for a person's IQ
B: young adults who are fit get higher scores in IQ tests
C:youngsters who are fit will more likely get college education
D: young people who are muscular and strong have a higher IQ

Ceasing to Wear Ties

1 It's useless.It's dirty.It spreads disease.That's why the British Medical Association in
the UK recently called for hospital doctors to stop wearing ties.
2 That leads to another question.Why does anyone wear a tie?Ties serve no purpose.
They do not cover any part of your body and keep you warm.They always seem to get
covered in food stains.Perhaps that is the purpose of the tie.It lets everyone know what
you just ate.
3 Ties have an odd history.Soldiers from Croatia,in Eastern Europe,served as
mercenaries（雇佣军）in various conflicts in the 17th century.They were identified by brightly
colored pieces of silk worn around the neck.Known as cravats（围巾）,these became a
popular fashion item in France and eventually evolved into the tie.
4 It's an interesting story,but it doesn't tell us why men want to put useless pieces of cloth
or silk around their necks.The answer seems to be about identification（身份证明）.In the
19^th-century Britain,ties were used by universities,military regiments（团）,sports clubs,
schools and gentleman's clubs.Each tie was in a particular set of colors which identified the
wearer as a member of that organization.Wearing ties was also the mark of Britain's most
powerful classes.That made the tie itself a symbol of power and respect.And that led it to
be adopted by a much larger class一the business class.
5 You cannot wear a tie if you work with machinery.So wearing a tie became a sign that
you were a man who used his brain to make a living,rather than his hands.It showed you
were serious.It showed you were a professional.It meant that everyone who wanted a job
in business had to wear one.It was just impossible to take seriously a man who did not wear
a piece of colored silk around his neck.This is how millions of people came to wear ties
across the world.
6 Is there a future for ties?The signs are not promising.Many political leaders,including
British Prime Minister Tony Blair,now go without ties.

People wore different ties in Britain in the 19^th century to show that________.
A:they were workmen
B:they were members of different organizations
C:hospital doctors stop wearing ties
D:who does not always wear a tie
E:who served as mercenaries in many conflicts in the 1 7th century
F:who does not want to live like a king
