11."If you run for more than five minutes at any time,you might need a pair of running shoes."Advises Stephen Pribut,a US sports expert.Running shoes are highly technical footwear.The provide stability(牢固) while bearing up to three times the wearer's body weight.But it's not easy to find the right pair.Finding the right running shoes is something of an art,or a science and a feel.
The science part begins with the shape of the arch(弓) of your foot,which anyone can find out at home with this quick experiment:Put your foot in water and place it on a piece of brown paper.If you see a"C"shape on the paper when you remove your foot,you have a rare high arch.If the shape looks more like a rectangle,that means you have flat feet.See something in between?That's a normal arch.
Conveniently for shoppers,shoe companies nowadays divide their shoes in three categories:neutral ( for high arches),stability ( for normal or low arches) and motion control (for flat arches).So you'll know which type suits you.
At this point,most people would just grab an appealing shoe and try it on,But professionals would do a few quality-control tests.First,you bend the shoe toe to heel to see where it bends.If it's not at the forefoot---where the foot actually be bends,be afraid.Then you grip both ends and twist in opposite directions.If you can twist it like a tower,it means there's zero support.Finally,you squeeze(挤) the heel in both directions.A stable heel won't   cave in.
Now you need to check the mold(模子) that shapes the inside of the shoe:whether its wide or narrow in the mid-foot,how it sits on the heel and how roomy the toe box is.
It's wise to make the shoe purchase in the late afternoon,to allow for any swelling(肿胀) that your feet do throughout the day.Toes also decide sizing choices.The rule is that you need a finger's width from your longest toe (whether that's your big one or not) to the end of the shoe.

45.What is the main idea of this passage?C
A.Advantages of wearing running shoes fitting you.
B.Ways to get to know about the shape of the arch of your foot.
C.Advice on how to choose the right pair of running shoes.
D.Best time to buy a pair of running shoes.
46.If the arch of your foot look like a"C"shape,you haveB.
A.a normal arch       B.a high arch        C.a flat arch       D.a low arch
47.The underlined phrase"cave in"most probably meansA.
A.bend            B.stretch          C.shake          D.crash
48.Why is the late afternoon the ideal time to go shopping for shoes?B
A.We are likely to be more patient in the afternoon.
B.Feet usually become larger late in the day.
C.The toes become longer late in the day.
D.The arch of our feet will be in best shape in the afternoon.

分析 本文主要写了如何选择一双合适的跑鞋,并描述了对于跑鞋的研究,不同的脚以及体重要有不同的跑鞋的设计.

解答 45.答案是C.细节理解题,根据文章第一段最后一句"Finding the right running shoes is something of an art,or a science and a feel"找到合适的跑鞋是一门艺术亦或是一种科学,可见本文主要是写如何选择一双合脚的跑鞋.所以答案选C.
46.答案是B.细节理解题,根据文中句子"you have a rare high arch"你拥有一个罕见的高弓,所以答案选B.
47.答案是A.猜测词义,根据前面的描述"If you can twist it like a tower."如果你能把脚扭成一张弓,可见这里的cave in应与bend同意"弯起来"的意思,所以答案是bend.
48.答案是B.推理判断题,根据文中句子"to allow for any swelling(肿胀) that your feet do throughout the day",可以推断一天当中下午以后是一天中最容易肿大的时候,所以答案选B.

点评 阅读理解题测试考生在阅读基础上的逻辑推理能力,要求考生根据文章所述事件的逻辑关系,对未说明的趋势或结局作出合理的推断;或根据作者所阐述的观点理论,对文章未涉及的现象、事例给以解释.考生首先要仔细阅读短文,完整了解信息,准确把握作者观点.

19.People believe that climbing can do good to health.Where can you learn the skills of climbing then?If you think that you have to go to the mountains to learn how to climb,you're wrong.Many Americans are learning to climb in city gyms (体育馆).Here,people are learning on special climbing walls.The climbing wall goes straight up and has small holding places for hands and feet.
How do people climb the wall?To climb,you need special shoes and a harness (保护带) around your chest to hold you.There are ropes (绳索) tied to your harness.The ropes hold you in place so that you don't fall.A beginner's wall is usually about 15feet high,and you climb straight up.There are small pieces of metal that stick out for you to stand on and hold on to.Sometimes it's easy to see the next piece of metal.Sometimes,it's not.The most difficult part is to control your fear.It's normal for humans to be afraid of falling,so it's difficult not to feel fear.But when you move away from the wall,the harness and the ropes hold you,and you begin to feel safe.You move slowly until you reach the top.
Climbing attracts people because it's good exercise for almost everyone.You use your whole body,especially your arms and legs.This sport gives your body a complete workout.When you climb,both your mind and your body can become stronger.

21.What can we infer from the passageA?
A.People are fairly interested in climbing nowadays.
B.It is impossible to build up one's body by climbing.
C.People can only learn the skill of climbing outdoors.
D.It is always easy to see holding places in climbing.
22.The most difficult thing to do in wall climbing isB.
A.to tie ropes to your harness          
B.to control your fear
C.to move away from the wall         
D.to climb straight up
23.The word"workout"underlined in the last paragraph most probably meansB.
A.settlement         
B.exercise       
C.excitement        
D.tiredness
24.Why does the author write this passageD?
A.To tell people where to find gyms.
B.To prove the basic need for climbing

D.introduce the sport of wall climbing.

6.A.Study the levels of stress by comparison.
B.Higher level of stress causes more trouble.
C.Milder stress does more harm than expected.
D.A certain level of stress is efficient in working conditions.
E.Always pay enough attention to mild stress.
F.Modern social conditions may lead to stress.
61.C
Even relatively mild stress can lead to long term disability and an inability to work,reveals a large population based study published online in the Journal of Epidemiology (流行病学) and community Health.It is well known that mental health problems are associated with long term disability,but the impact of milder forms of psychological stress is likely to have been underestimated (低估),say the authors.
62.A
Between 2002 and 2007,the authors tracked the health of more than 17,000 working adults up to the age of 64,who had been randomly selected from the population ill the Stockholm area. All'participants completed a validated(经验证的) questionnaire at the start of the study to measure their mental health and stress levels,as well as other aspects of health and well-being.    
63.B
During the monitoring period,649 people started receiving disability benefit---203 for a mental health problem and the remainder for physical ill health.Higher levels of stress at the start of the study were associated with a significantly greater likelihood of subsequently being awarded long term disability benefits.But even those with mild stress were up to 70%.more likely to  receive disability benefits,after taking account of other factors likely to influence the results,such  as lifestyle and alcohol intake. One in four of these benefits awarded for a physical illness,such as high blood pressure; angina(心绞痛),and stroke(中风),and almost two thirds awarded for a  mental illness,were likely to have been caused by stress.
64.F
The authors say that it is important to consider their findings in the context of modern working life,which places greater demands on employees,and social factors,such as fewer close personal relationships and supportive networks.
65.E
These factors lead them to ask,"Are the strains and demands of modern society commonly exceeding(超出)human ability?And they conclude that while mild stress should riot.be over-medicalised,their findings suggest that it should be taken more seriously than it is.
