If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers and nonjoggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as nonjoggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries (动脉). Over time, this can cause serious injuries.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”
The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and longdistance running and cycling. According to Jacob Louis Marott, another researcher involved in the study,“You don't actually have to do that much to have a good impact on your health.And perhaps you shouldn't actually do too much.”
1.The underlined word “strenuous” in Paragraph 1 is closest in meaning to “________”.
A.hard B.regular
C.practical D.flexible
2.The author presents some figures in Paragraph 2 to ________.
A.suggest giving up jogging
B.show risks of doing sports
C.provide supportive evidence
D.introduce the research process
3.According to the scientists, why is too much exercise harmful?
A.It may injure the heart and arteries.
B.It can make the body tired out.
C.It will bring much pressure.
D.It consumes too much energy.
4.What can be inferred from the text?
A.Jogging is the best exercise.
B.More exercise means a healthier life.
C.Marathons runners are least likely to die.
D.Proper exercise contributes to good health.

More and more people take part in marathons these days – over 30,000 people will run the London Marathon this weekend, for instance. But it’s not just the 26 miles and 385 yards that could be a daunting prospect. “I have to admit to being completely frustrated by the blocking and for 18-19 miles was just keeping away from people and being held up,” one participant grumbled after the 2012 London Marathon. “I had to overtake a lot of people and ended up with bruised(淤肿的)forearms from all the elbows,” said another.
How do such crowding problems arise, and could they be reduced? Some researchers believe that we can find the answers through a more familiar system in which jams appear – road traffic flow. Martin Treiber, of the Technical University of Dresden in Germany, has previously developed models for traffic flow. One of the first attempts to model traffic flow was made in the 1950s by James Lighthill and his collaborator Gerard Whitham of Manchester University. They considered the traffic as a kind of liquid flowing down a pipe, and looked at how the flow changes as the fluid gets denser(浓稠). At first the flow rate increases as the density increases, since you simply get more stuff through in the same period of time. But if the density becomes too high, there’s a risk of jams, and the flow rate drops sharply.
Treiber’s model of a marathon uses this same principle that the flow rate first increases and then decreases as the density of runners increases, thanks to an sudden switch from free to crowded flow. He assumes that there is a range of different preferred speeds for different runners, which each maintains throughout the race. With just these factors, Treiber can calculate the flow rate of runners, knowing the “carrying capacity”(承载能力)at each point on the route.
This allows Treiber to figure out how blocking might depend on the race conditions – for example, for different starting procedures. Some marathons start by letting all the runners set off at once (which means those at the back have to wait until those in front have moved forward). Others assign runners to various groups according to ability, and let them start in a series of waves.
Treiber has applied the model to the annual Rennsteig half-marathon in central Germany, which attracts around 6,000 participants. The traditional route had to be changed in 2013, because the police were no longer willing to close a road to ensure that runners could cross safely. It could pass either over a 60m wooden bridge or through a tunnel. Treiber used his model to predict the likely blocking caused in the various options. The model predicted that a mass start would risk an overload of runners if the bridge were to be used. Only by moving the starting point further back from the bridge could the danger be avoided – and even then, if some of the numbers assumed in the model were only slightly inaccurate, there was still a risk of jams at the bridge. On the other hand, no dangerous blocking seemed likely for the tunnel route. The run organizers consulted Treiber’s team, and eventually chose this option.
1.What is the worst thing while running a marathon?
A. The long distance. B. Too many participants.
C. The dangerous blocking. D. Serious injuries in forearms.
2.Which of the following statements is true?
A. James Lighthill is the first expert trying to model traffic flow.
B. The denser the flow is, the faster the flow rate becomes.
C. The flow rate increases in the beginning because fewer people passed together.
D. The flow rate increases first and then decreases later when the flow is too denser.
3.What is NOT true about the Rennsteig?
A. It has much less participants than the London Marathon in 2014.
B. It has a shorter distance than the London Marathon.
C. The route was changed because the traditional one is not safe any longer.
D. The participants running this marathon will pass a tunnel because this choice is safer.
4.What’s the main idea of the passage?
A. Make a comparison between marathon and road traffic.
B. Running a marathon is somewhat dangerous if it is not well organized.
C. Introduce a new technology to solve the blocking problem in marathon.
D. Some advice for people who are to run a marathon.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cell, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometimes between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs (The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones).
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
1.What are the present major killers according to the writer? (No more than 10 words)

While you may think that being smart and talented would logically make someone successful in running a business, unfortunately, this is often not the case.
This problem starts back in school when the stressful “group projects” are first assigned .The smartest don’t want to risk their grade in the class by dividing the work equally and hoping that an average student does his part well. They just take over and do the whole project themselves.
And thus begins the smart-people work cycle. The smartest people do just about everything better than most everyone else until it comes to running a business. They are not better. A smart person who can’t stand someone else doing a job badly does everything himself. Then, he is stuck with the one-man band “job-business” and ends up not being able to grow. However, it is quite interesting and strange that some “slackers” ( a person who is lazy and avoids work) are better suited to be a business leader than the “smart” people.
Smart and talented people often have a gift for the unusual, complicated or different. They don’t like to follow the KISS principle (keep it simple, stupid), which is required to make a business succeed. Maybe you think the global presence of McDonald’s complex, but in reality, in the company, every single task is broken down into easy-to-follow steps and everything has been standardized. These successful companies have just a few smart enough people to run the majority of the tasks in a way that can’t be screwed up by their average employees. So, being smart or talented isn’t going to help you unless you can use those smarts to figure out a way to simplify those tasks that will make a business successful.
Another issue with the smart people starting businesses is that they often have the most to lose. The smarter you are, the more options you have available to you. You will be able to make a lot of money in various fields and have room in your career to become promoted. This means that when you start a business, you have a lot more to risk than those who are not equally smart. This is often referred to as the “golden handcuffs” dilemma.
So, don’t be surprised when the person “MOST Likely to Succeed” from high school ends up as an employee and it is one average student that finds success in his or her own business.
1.In group work, smart students often take over the whole project because they believe ____.
A. the work is not divided equally
B. they can perform better than others
C. the group projects are too stressful
D. average students are unwilling to participate
2.McDonald’s is used as an example to prove that ____.
A. a business calls for smart people’s talent
B. average employees can perform complex tasks
C. smart people are important for a successful business
D. simplified tasks are required for the success of a business
3.The underlined expression in Paragraph 5 refers to the situation where smart people ____.
A. have fewer options in a company
B. risk more when starting business
C. are unwilling to put money to a business
D. can have a good income in many different fields
4.What is the best title for the passage?
A. Potentials for Success
B. Bases for Business
C. The Ordinary Achieve Bigger Success?
D. Talent Means Successful Business?

You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers(同龄人).
Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children.
Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet.
Dr.Berge,one of the study authors,said:“This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions(解决办法).”
According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight.
Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index(指数),but fathersgot less physical activity—about five hours weekly ,compared to almost seven hours among chidless men.
The study has several limitations-there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum(产后)depression,which might affect their eating and exercise habits.
1.What does the author mainly aim to tell us in the passage?
A.Childless couples live a much happier life than those with children. |
B.Mothers will be unhealthy because of the postpartum deprdession |
C.Couples of young children eat more fatty foods and lead unhealthier lives. |

4.What Dr.Berge says in Paragraph 4 suggests that________.
A.Parents should pay more attention to their chidren |
B.doctors should do something with parents'high-risk time period |
C.the study has drawn attention of doctors and young parents |
D.parents should not be blamde for having an unhealthy lifestyle |

Many of us listen to music while we work, thinking that it will help us to concentrate on the task at hand. And in fact, recent research has found that music can have beneficial effects on creativity. When it comes to other areas of performance, however, the impact of background music is more complicated.
The idea that listening to music when working is beneficial to output probably has its roots in the so-called “Mozart effect”. Put simply, this is the finding that spatial rotation performance(空间旋转能力) is increased immediately after listening to the music of Mozart, compared to no sound at all.
How sound affects performance has been the topic of research for over 40 years, and is observed through a phenomenon called the irrelevant sound effect. To study irrelevant sound effect, participants in the research are asked to complete a simple task which requires them to recall a series of numbers or letters in the exact order in which they saw them. The tricky thing is being able to do this while ignoring any background noise.
Two key characteristics of the irrelevant sound effect are required for its observation. First, the task must require the person to use their rehearsal abilities(复述能力), and second, the sound must contain acoustical variation(声学变化). Where the sound does not vary much acoustically, the performance of the task is much closer to that observed in quiet conditions.
The irrelevant sound effect itself comes from attempting to process two sources of ordered information at the same time—one from the task and one from the sound. Unfortunately, only the former is required to successfully perform the recall task, and the effort in ensuring that irrelevant order information from the sound is not processed actually hinders(阻碍) this ability.
A similar conflict is also seen when reading while in the presence of lyrical music. In this situation, the two sources of words—from the task and the sound—are in conflict. The cost is poorer performance of the task in the presence of music with lyrics.
What this all means is that whether having music playing in the background helps or hinders performance depends on the task and on the type of music, and only understanding this relationship will help people maximize their productivity levels.
1.“Mozart effect” is mentioned to ________.
A. explain how music can relax people
B. show music can improve performance
C. advise people to listen to Mozart music
D. stress Mozart music gains wide attention
2.It can be inferred that participants in the research ________.
A. have improved their rehearsal ability
B. perform better in the quiet conditions
C. ignore the background noise successfully
D. prefer the music with great sound variation
3.Paragraph 6 is written to ________.
A. support an idea B. make a contrast
C. introduce a topic D. describe a fact
4.What is the best title for the passage?
A. Music shapes your life
B. Music develops your creativity
C. Choose quiet music for your work
D. Does music make you concentrate?
