19.It is common sense that children who walk or cycle to school have a lower risk of obesity than those by car.But driving your youngsters to the gates could also cause their academic work to suffer.
Researchers found children who were driven to school,or who took public transport,had poorer concentration levels than those who took a more active route such as walking or cycling.
The joint study by researchers at two Danish universities found the regular exercise could advance a student up to half a year in their studies.Children who were driven to school,or who took public transport,performed less well in a test measuring concentration levels,than those who had walked or cycled.
The results surprised the researchers,as their hypothesis(假设) originally focused on the effects of eating breakfast and lunch on pupils'ability to concentrate.
"The exercise one uses to transport oneself to school is reflected in the level of concentration one has about four hours later,"Niels Egelund,a co-author of the report said."The results showed that having breakfast and lunch has an impact,but not very much compared to having exercise."
"As a third-grade pupil,if you exercise and bike to school,your ability to concentrate increases to the equivalent of someone half a year further in their studies,"he added.
In the survey,taken by 19,527 pupils aged five to 19 years old,participants were asked about their exercise habits and were then given a basic test measuring their concentration.
"Most people know the feeling of being refreshed after having exercised,but it is surprising that the effect lasts for so long,"Egelund said.
Previous research from the university of Montreal has found that exercise helps our brains make better use of oxygen.It may also reduce mental fatigue(疲劳) and sharpen your thinking in between gym sessions.And last week Swedish researchers said they found that muscular boys will live longer than their weaker friends.
And even if they are overweight by the time they get to adulthood,those with stronger muscles tend to live longer.

51.What is the best title of this passage?D
A.Exercise--Refresh you           B.Exercise--Look slim
C.Exercise--Live longer           D.Exercise--Learn faster
52.Which of the following is NOT the result of the research from the University of Montreal?B
A.Exercise helps our brain make the most of oxygen.
B.Exercise can improve the level of concentration.
C.Exercise can make you sharp-minded.
D.Exercise can decrease mental fatigue.
53.According to the passage,which of the following statements is correct?D
A.Having breakfast and lunch has a greater impact on concentration than having exercise.
B.Children driven to school perform worse in all tests.
C.Having exercise can refresh us but it doesn't last long.
D.Eating breakfast and lunch can affect children's ability to focus.
54.Children driven to school performed badly in their academies work in thatC.
A.they are too lazy                   B.they are not healthy
C.they are not focused                D.they are not smart.

分析 本文是一篇科普类文章,主要讲述了研究者发现开车,坐交通工具去上学的学生和那些走路或骑车上学的学生相比,注意力不够集中,这是因为锻炼可以帮助大脑充分利用氧气,减少精神疲劳,使思维敏捷,从而使注意力更集中.

7.Mobile phone has become a problem for middle schools.Some middle schools in Australia have banned students from carrying mobile phones during school hours.
Mobile phone use among children has become a problem for the school this year.Several children have got mobile phones as Christmas gifts,and more students will want them.
Mary Bluett,an official,said mobile phone use is a distraction (分心的事) to students during school hours and it also gives teachers so much trouble in their classrooms.Teachers were also saying that sometimes students might use phone messages to cheat during exams.
She said some schools had tried to ban mobile phones.Some parents felt unhappy because they couldn't get in touch with their children.
Many teachers said students should not have mobile phones at school,but if there was a good reason,they could leave their phones at school office.They also said there were many reasons why the students should not have mobile phones at school:they were easy to lose and were a distraction from studies.
Many people say that they understand why parents would want their children to have phones,but they think schools should let the students know when they can use their mobile phones.

40.Some middle schools in Australia have banned students from carrying mobile phonesC.
A.because they are students
B.when they are free
C.when they are at school

11.The world is filled with smart,talented,educated and gifted people.We meet them every day.A few days ago,my car was not running well.I pulled it into a garage,and the young mechanic had it fixed in just a few minutes.He knew what was wrong by simply listening to the engine.I was a mazed.The sad truth is that great talent is not enough.
I am constantly shocked at how little talented people earn.I heard the other day that less than 5percent of Americans earn more than $100,000a year.A business consultant who specializes in the medical,trade told me how many doctors and dentists struggled financially.It was this business consultant who gave me the phrase,"They are one skill away from great wealth."
There is an old saying that goes,"Job means‘just over broke (破产)'."And unfortunately,I would say that the saying applies to millions of people.Because school does not think financial intelligence is intelligence,and most workers"live within their means".They work and they pay the bills.Instead I recommend young people to seek work for what they will learn,more than what they will earn.
When I ask the class I teach,"How many of you can cook a better hamhurger than McDonald's?"almost all the students raise their hands.I then ask,"So if most of you can cook a better hamburger,how come McDonald's makes more money than you?"The answer is obvious:McDonald's is excellent at business systems.The reason why so many talented people are poor is that they focus on making a better hamburger but know little or nothing about business systems.The world is filled with talented poor people.They focus on perfecting their skills at making a better hamburger rather than the skills of selling and delivering the hamburger.

71.The author mentions the mechanic in the first paragraph to show thatA.
A.he is just one of the talented people
B.he is ready to help others
C.he has a sharp sense of hearing
D.he knows little about car repairing
72.The underlined part in the third paragraph can be best replaced by"D".
A.spend more than they can afford
B.do in their own way
C.live in their own circle
D.live within what they earn
73.Why do talented people earn so little according to the author?B
A.They don't work hard enough.
B.They lack financial intelligence.
C.They don't make full use of their talents.
D.They have no specialized skills.
74.The success of McDonald's lies in itsB.
A.skills at making hamburgers
B.good business systems
C.talented workers
D.excellent service
75.The main purpose of the author is to tell usC.
A.how young people can find a satisfactory job
B.what schools should teach students
C.why so many talented people are poor
D.how McDonald's makes much money.
