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_________(51)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__________(52)1._________(1.)
2 million Swedish men doing military service who were born between 1950 and
1976._________(1976.)
The research group analyzed the ________(53)of both physical and IQ tests the youngsters took
right after they started serving the army.
The study shows a clear link _________(54)good physical fitness and better results for the IQ test.
The strongest links are for ________(55)thinking and verbal comprehension.But it is only fitness that
plays a _________ (56)in the results for the IQ test,and not strength."Being fit means that you also have
good heart and lung __________(57)and that your brain gets plenty of oxygen."says Michael Nilsson,pro-
fessor 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_________(58).We are
also seeing that there are growth factors that are important."
By analyzing data for twins,the researchers have been________(59)to determine that it is primarily
environmental factors and not genes that___________(60)the link between fitness and a higher IQ.
"We have also shown that those youngsters who _______(61)their physical fitness between the ages
of 1 5 and 1 8 increase their performance."says Maria Aberg,researcher at the Sahlgrenska Academy and
physician at Aby health centre."This being the case,physical education is a_______(62)that has an
important place in schools,and is an absolute must________(63)we want to do well in math and other
theoretical subjects."
The researchers have also compared the results from fitness tests during national service_______(64)
the socioeconomic status of the men later in life.Those who were fit at I 8 were more__________(65)to go
into higher education,and many secured more qualified jobs.

In the dark night of the desert,a group of U.S.Air Force scientists is testing a new device for a missile to target.Designed to seek out the heat of an enemy aircraft engine,it is now going through its paces by tracing the movement of a flashlight waving thirty feet away in the darkness.A hundred yards away,unseen by the man,a rattlesnake sliding between the stones senses a patch of warmth. Although the snake's mechanism is small enough to be packed into a head the size of a nut,it can detect a change in temperature of one-thousandth of a degree.With a sound the snake closes in and strikes for the kill.
Whenever we look in the animal world we find the same story.Almost anything that man can do,nature has already done better. So,it is for the purpose of learning from nature that a new science called bionics has grown up.Its aim is to find out how animal's instruments work so that man can copy them for his own purpose.
Imagine being able to know a friend several miles off by his smell. Male silk moths can do this. Their antennae are so sensitive to the chemical odor of female moths that they can detect their presence by picking up only one molecule of the chemical.Even with their most sensitive instruments, human cannot approach this perfection.
Studying beetle's eyes has already paid off. A group of scientists in Germany found that a beetle can accurately measure with its eyes the speed of moving background.After finding out how a beetle accomplishes this scientists built a machine that operated on the same principle.This instrument is able to determine the ground speed of moving aircraft with a high degree of accuracy.

The goal for bionics is to______.
A:explain how animal devices work
B:copy animal processes with man-made machines
C:prove the usefulness of this science
D:apply science to the study of animals
