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.

Language and Infants
How important is language to young children?Is language,like food,a basic human need without which a child at a critical period of life can be starved and damaged?Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century it may be.Hoping to discover what language a child would speak if he heard no mother tongue he told the nurses to keep silent.
Within the first year,all the infants died.People realized clearly in this case that there was more than deprivation of language._______(46)Without good mothering,in the first year of life especially,the capacity to survive is seriously affected.
Today no such cruel deprivation is allowed to exist that ordered by Frederick.Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the cues and signals of the infant,whose brain is programmed to mop up language rapidly.There are critical times,it seems,when children learn more readily._______(47)A bird learns to sing and to fly rapidly at the right time,but the process is slow and hard once the critical stage has passed.
Linguists learn that speech milestones are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ (Intelligence Quotient).At twelve weeks a baby smiles and utters vowel-like sounds;at twelve months he can speak simple words and understand simple commands;at eighteen months he has a vocabulary of three to fifty words._______(48)
Recent evidence suggests that an infant is born with the capacity to speak.What is special about Man's brain,compared with that of the monkey,is the complex system which enables a child to connect the sight and feel of,say,a teddy-bear with the sound pattern"teddy-bear"._______ (49)
But speech has to be triggered,and this depends on interaction between the mother and the child,where the mother recognizes the cues and signals in the child's babbling,clinging,grasping,crying,smiling,and responds to them._______(50)Sensitivity to the children's non-verbal cues is essential to the growth and development of language.
________（49）
A:At three he knows about 1,000 words which he can put into sentences,and at four his language differs from that of his parents in style rather than grammar.
B:What was missing was good mothering.
C:Lots of information about benefits of baby signing and best ways to go about it can be found.
D:Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals.
E:If these sensitive periods are neglected,the ideal time for acquiring skills passes and they might never be learned so easily again.
F:And even more incredible is the young brain's ability to pick out an order in language from the hubbub of sound around him,to analyze,to combine and recombine the parts of a language in novel ways.

Women,Keep Dieting!
To most women who are trying to keep slim,dieting can seem to last a lifetime,or to be more exact,31 years,for researchers have found that is how long the average woman spends on a diet over the course of her life.
A university did a research on diet of British people for as long as 10 years,whose result revealed such a picture.British women spend averagely six months a year counting the calories and more than one fifth are on a permanent diet throughout their lifetime in a seemingly never-ending pursuing the perfect figure.
However,they aren't the only ones waging a constant fight against the loose fat. The average adult male spends 28 years losing weight,the poll has discovered.It found that over a tenth of the UK population is currently dieting in a bid to shed the pounds after feasting on festive treats over the Christmas period.Though holding the best intentions,three quarters of those who began their New Year with the firm resolution to lose weight give up by the end of the week.The average diet lasts 5.5 weeks,with the post-Christmas fast being even shorter at just three weeks.Half of slimmers throw in the towel due to lack of determination,while a quarter of interviewee answered that they give up because the strict diet regime makes them moody or depressed.The most determined dieters of all are aged from 45 to 64,almost a quarter spending up to a year slimming. In comparison,those aged between 18 and 24 are more likely to be yo-yo dieters,with a fifth giving up within a month.
The survey of 1,446 of men and women found that nearly two thirds of the UK population are unhappy with their body and feel that being thinner would make them happier.
For women,looks are more important,with over half reporting that they diet to wear fashionable clothes and a third of those surveyed said they watched their weight in a bid to feel more attractive. But in comparison,men are more focused on their long-term well-being,with over a third saying they wanted to lose weight to be more healthy.
Which statement is NOT true according to the passage?
A:Averagely,British women are on diet six months each year.
B:Less than one fifth of British women are on a permanent diet throughout their lifetime.
C:Nearly two thirds of the UK population are unhappy with their body.
D:The most determined dieters of all are aged from 45 to 64.

Transport and Trade
1.Transport is one of the aids to trade.By moving goods from places where they are plentiful to places where they are scarce,transport adds to their value.The more easily goods can be brought over the distance that separates producer and consumer,the better for trade.When there were no railways,no good roads,no canals,and only small sailing ships,trade was on a small scale.
2.The great advances made in transport during the last two hundred years were accompanied by a big increase in trade.Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand,for instance.Quicker transport makes possible mass-production and big business, drawing supplies from,and selling goods to,all parts of the globe.Big factories could not exist with-out transport to carry the large number of workers they need to and from their homes.Big city stores could not have developed unless customers could travel easily from the suburbs and goods delivered to their homes.Big cities could not survive unless food could be brought from a distance.
3.Transport also prevents waste.Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns.Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally.Foods which at one time could be obtained only during a part of the year can now, be obtained all through the year. Transport has raised the standard of living.
4.By moving fuel,raw materials,and even power,as,for example,through electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before.Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes,the longer the distance over which goods can profitably be carried.Countries with poor transport have a lower standard of living.
5.Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communication,like telephones,cables and radio,send information about prices,supplies,and changing conditions in different parts of the world.In this way,advanced communication systems also help to develop trade.
In the trade of modern society the transmission of information plays as important a role as_______.
A:to send goods to various parts of the world
B:at any time during the year
C:has greatly promoted trade
D:is it possible to produce on a large scale
E:the transport of goods
F: it is possible to produce on a large scale
