35、a higher IQ1 and are morelikelyto 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 doin
36、g military service who were born between 1950 and 1976.The research group analysed theresultsof both physical and IQ tests the youngsters took right after they started serving the army.The study shows a clear linkbetweengood physical fitness and better results for the IQ test. The strongest links ar
37、e forlogicalthinking and verbal comprehension. But it is only fitness that plays arolein the results for the IQ test,and not strength.“Being fit means that you also have good heart and lungcapacityand that your brain gets plenty ofoxygen,says Michael Nilsson,professor at the Sahlgrenska Academy and
38、chief physician at the Sahlgrenska University Hospital.“This may be one of the reasonswhywe can see a clear link with fitness,but not with muscularstrength.We are also seeing that there are growth factors that are important.”By analysing data for twins,the researchers have beenableto determine that
39、it is primarily environmental factors and not genes that explain the link between fitness and ahigherIQ.“We have also shown that those youngsters whoimprovetheir physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Mafia Aberg,researcher at the Sahlgrenska Academ
40、y and physician at Aby health centre.“This being the case,physical educationis 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 testsduringnational servic
41、e with the socio-economic status of the men later in life. Those who were fit at 18 were more likely to go into highereducation,and many secured more qualified jobs.第十一篇11 Migrant WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another.
42、While some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East,1 where increased oil incomes have enabled many countries to call in outsiders to improve local facili
43、ties. Thus the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, including South Korea and Japan.In view of the difficult living and working conditions in the Middle East, 2 it is not surprising that the pay is
44、high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. 3 This increases the net amount of pay received by
45、 visiting workers and is very popular with them.Sometimes a disadvantage has a compensating advantage. For example, the difficult living conditions often lead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save lar
46、ge sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects m
47、igrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case , migran
48、t workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.第十二篇 DreamsEveryone can dreamIndeed, everyone does dreamThose who claim that they never dream at all actually dream just as frequently as the rest of us, though they may not remem
49、ber anything about itEven those of us who are perfectly aware of dreaming night after night very seldom remember those dreams in great detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our senses , so that we appear to exper
50、ience sound, touch, smell, and tasteOne of the worlds oldest known written documents is the Egyptian Book of DreamsThis volume is about five thousand years old, so you can see that dreams were believed to have a special significance even thenMany ancient civilizations believed that you should never
51、ask a sleeping person as, during sleep, the soul had left the body and might not be able to return in time if the sleeper were suddenly awoken .From ancient times to the present day ,people have been making attempts to interpret dreams and to explain their significanceThere are many books available
52、on the subject of dream interpretationalthough unfortunately there are almost as many meanings for a particular dream as there are books第十三篇 Scientists Develop Ways of Detecting Heart AttackGerman researchers have come up with a new generation of defibrillators and early-warning software aimed at of
53、fering heart patients greater protection from sudden death from cardiac arrest.In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases are caused by disruption to the hearts rhythm. Those most at risk are patients who have already suffered a heart at
54、tack, and for years the use of defibrillators has proved useful in diagnosing life-threatening disruption to heart rnythms and correcting them automatically by intervening within seconds. These devices take on a range of functions, such as that of pacemaker.Heart specialists at Freiburgs University
55、Clinic have now achieved a breakthrough with an implanted defibrillator capable of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of acute blood-flow problems and a pending heart attack. It will be implanted in patients for the first t
56、ime this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders of ECG data more precise.The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this reason under
57、go regular ECGs. “Many of the current programs only get into account a linear correlation of the data. We are, however, making use in a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system,” Hagen Knaf says, “In this way changes in the heart beats over time can be monitored and individual variations in patients taken into account.” An old study of ECG data, based upon 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show that the new softwa
