Winter running is the best way to lose winter weight. But before heading out, make sure you have a solid plan. You don't want to come across accident along the way.{#blank#}1{#/blank#}

    Wear the Right Shoes

    The right shoes will depend on the road. You should wear shoes that are made for the kind of surface you run on. For example, if you are running on slippery surfaces, you want shoes with great friction(摩擦力).{#blank#}2{#/blank#} When trying out a pair of running shoes, check the fit, feel and ride of the shoes. These elements（要素）are important once you take your new shoes out for a run.

    Warm Up

    Warm-up is an important part to keep fit. Especially if temperatures drop and your muscles are stiff(僵硬的) from the cold!{#blank#}3{#/blank#} It also prepares the muscles for the intense (激烈的) activity ahead. The cold climate won't feel as cold when you do warm ups. This is because blood flows much faster after a good warm up!

    Deal with Wind

    {#blank#}4{#/blank#} The key is to run into the wind and finish by running against it . This keeps icy wind from blasting(用力撞击) your face. To prevent any injuries or accidents, break your run into small parts.{#blank#}5{#/blank#}You can use certain creams on the nose and cheeks to prevent frostbite(冻疮).Don't skip your sun-block if you're running during the day. UVB(紫外线) passes through the clouds. Running for an extended period on a cloudy day will still damage the skin!

A. Don't run in the wind

B. Running makes you warm

C. Warming up prevents injuries

D. It's hard to run if it's too windy

E. Your shoes should fit very well so you don't slip

F. Here we are giving you important tips to remember

G. It also helps to keep the skin protected from the wind

How to stay focused in class

    Being relaxed during class is a bad habit, and it is also bad to your grade. Focusing in class not only proves to teachers that you are a capable student but also shows that you have the ability to control yourself, which will be very important.

    {#blank#}1{#/blank#} No matter how much you want to sit with your friends during the class, try your best to avoid them. Talking with friends around you is not going to give you the focus in class. This will get you into trouble.

    Look at teacher and make eye contact. Your teacher is not just standing up there talking.{#blank#}2{#/blank#} Show the teacher that he or she has your full attention by looking them in the eye. This person should have your full attention at all times during class.

Take notes. By taking notes, you'll be able to "get into" the lesson. Write down key points as your teacher speaks. And listen to the key phrases such as "This is important" "This is the main idea" "This will be the test" etc.{#blank#}3{#/blank#}

    Get involved in class discussions. This is a wonderful way to become a more focused, successful student. When a teacher asks a question, offer to answer it.{#blank#}4{#/blank#} This shows the teacher that you are listening carefully during the class.

    Ask a question.{#blank#}5{#/blank#} This really shows your teacher that you want to be better, and can recognize the things you are having difficulty with. Chances are that someone else in the class has the same question （and was too afraid to ask!）. They'll be relieved, and so will you.

A. Avoid sitting with friends.

B. This can help you listen more attentively.

C. If he or she ask for an opinion, share your own.

D. Talking with friends makes you lose interest in class.

E. He or she is trying to give you an acceptable education.

F. The more quickly you answer, the more attention you pay.

G. If you don't understand something, never be afraid to ask.

    Much of the work in today's world is accomplished(完成) in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. {#blank#}1{#/blank#}Companies spend millions hiring top business people. Is their money well spent?

    {#blank#}2{#/blank#}They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.

    To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate(协调) their actions. {#blank#}3{#/blank#}In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." {#blank#}4{#/blank#}

    Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war(拔河比赛), whenever a person is added, everyone else pulls the rope with less force.

    {#blank#}5{#/blank#} An A-team may require a balance——not just A players， but a few generous B players as well.

A. It's not a simple matter to determine the nature of talent.

B. Sports team owners spend millions of dollars attracting top talent.

C. The group interaction and its effect drew the researchers' attention.

D. Stars apparently do not follow this basic principle of sportsmanship.

E. Several recent studies examined the role of talent in the sports world.

F. Building up a dream team is more complex than simply hiring the best talent.

G. This task interdependence distinguishes baseball from football and basketball.

    Britain's high streets are dying slowly

    Twenty years ago, the prosperous high street(繁华商业区) was the heart of most cities. It was crowded with customers. {#blank#}1{#/blank#}Nowadays, high streets are declining, with very few shops and shoppers. With about 14 shops down every day, Britain's high streets are dying little by little. {#blank#}2{#/blank#}It's fairly easy to understand. To start with, people are spending less because of the economic recession(衰退). On top of that, more and more people are using the Internet to do their shopping. And it is not easy for shopkeepers in the high streets, either. {#blank#}3{#/blank#}Finally, there are the out-of-town retail parks with free car parking that sell just about everything at very low prices. What can be done? Prime Minister David Cameron has hired Mary Portas, a British business woman and star of TV show Mary Queen of Shops, to bring some life back into Britain's high streets. She's talked about creating "magnets(磁石)" to attract people back to the centre. {#blank#}4{#/blank#}In one town, a bicycle rickshaw(人力车) service is delivering people's shopping to their homes. {#blank#}5{#/blank#}where children can be cared for while parents are shopping. Members of the public have also voiced their opinions. "My ideal shopping center is one where there's a wide selection of attractive looking shops, with cheap parking and good public transport links," said a 28-year-old man. "I'd like to see Night Shopping evenings where shops are open through to 10 pm or later," said a 22-year-old girl.

A. They have to pay increasing high rents.

B. But he is not the only one to solve the problem.

C. But that's all changed.

D. In another town, they set up night shopping centers,

E. In another town, they set up a nursery,

F. They can make a fortune overnight.

G. Why are high streets in such a desperate situation?

    Next time your plane lands, listen to the sound of the tyres hitting the ground. {#blank#}1{#/blank#} The tyres of cars, motorbikes and trucks are also often made of the same stuff.

    {#blank#}2{#/blank#}Workers cut the trunks of the trees and collect a white liquid called latex（乳胶）. In the nineteenth and early twentieth centuries, huge numbers of rubber trees were planted in countries including Malaysia, Burma and Brazil. Nearly half the rubber which is produced each year is natural rubber and there is always a need for more.

    Rubber trees are not easy to grow. {#blank#}3{#/blank#} Some trees survive while others die and it is all decided by their genes. British scientists have been working together to look at rubber trees. They have now discovered the "genome" (基因组) of the rubber tree. {#blank#}4{#/blank#} The genome contains all the information the plant or animal needs to grow. The genome for a plant such as a rubber tree is smaller than a human genome but it is still very long, which is why it has been so difficult to find. Scientists say the work has been like putting a picture puzzle together where all the pieces show blue sea and blue sky.

    Now scientists can use the rubber tree genome to produce stronger trees. By understanding the genome, they can change the DNA in rubber trees in useful ways. {#blank#}5{#/blank#}

A. Natural rubber comes from trees.

B. Regretfully, many forests are being severely destroyed.

C. This is the way genes fit together in very long chains of DNA

D. Stronger trees have played a more important role in producing tyres.

E. They are affected by changes in temperature, rainfalls, winds and diseases.

F. The reason why the tyres don't explode is that they are made of natural rubber.
G. In the future, it will be possible to grow trees which survive climate change and disease.
