            • 1. A recent survey showed that only 9percent of teens in the United States smoke cigarettes.That's down from 23percent in 2000.While this is good news for the US's overall health,tobacco(烟草) use is still a problem.
              Cigarettes can cause many diseases,such as cancer(癌症),lung diseases and heart problems.Although they know about the health problems,teenagers still smoke.So the campaign of the US Anti-smoking Organization is working to end teenage smoking.Their latest activity uses social media(社交媒体) to remind teenagers of the dangers of smoking.And the activity also encourages teens to learn the facts and become the generation that ends smoking.
              However,anti-smoking campaigns may have a new problem to worry about.According to a 2013report,the use of electronic cigarettes is on the rise.American high school students who reported having used an electronic cigarette rose from 4.7percent in 2011to 10percent in 2012.The increased use of e-cigarettes by teens is deeply troubling.It may become lifelong addicted(上瘾).Besides,we still don't yet understand the long-term effects(作用) of e-cigarettes.
              根据材料内容,选择最佳答案.

              We all want our skin(皮肤) to look good.If our skin is clear and healthy,it makes you feel better about yourself.How do you get great skin?Here are some suggestions.
              Protect your skin against the sun
              •If you are  going to be outside,especially in the sun,you should put on suncream(防晒霜) in summer.
              •Wear a hat to protect your face.A wide hat is the best,as it will protect your ears and neck as well.

            • 3. We all know that exercise is good for your health.But some kinds of exercise may be better than others.Running,for example,may help to protect against heart disease and other health problems.Running may also help you live longer.
              Recently,researchers studied more than 55,000adults.About a quarter of the adults have a good habit of running.The study found these runners were much healthier than non-runners.In fact,the runners lived,on average(平均),three years longer than the non-runners.
              Running may  be good exercise,but it can be difficult on the body.Here are commonly shared ideas among fitness experts(健身专家) to lower the risk of injury(受伤) for people who are new to running.
              ⊙Take it easy.
              Do not run too much,too soon or too fast.Most people get running injuries when they push themselves too hard.The body needs time to get used to increases in distance(里程) or speed.
              ⊙Get good running shoes.
              There is no single best shoe for every runner.You should find the shoe that offers the best fit and support for your feet.More importantly,you should have a new pair of shoes every 500to 800kilometers.
              ⊙Take good notes.
              Take time after each run to write down notes about what you did and how you felt.Look for things that happen again and again.For example,you may find that your knees hurt when you run sometimes.But perhaps you feel great when you have a rest between running days.These notes will help you make the best plan for running.

              61.The writer wants to tell us in the first paragraph    
              A.good health comes from running
              B.running is the best exercise
              C.health problem can be solved by good exercise
              D.not all exercise is equally(同样的)good
              62.In the second paragraph,we know    
              A.a good habit of running may help you live longer
              B.the number of non-runners was getting smaller
              C.three quarters of 55,000adults were new to running
              D.the hope to live three years longer drives people to exercise
              63.Increases in distance or speed depend on    
              A.what the  fitness experts say   
              B.whether you have the best shoes
              C.how your body feels   
              D.why you start running
              64.The purpose of taking notes is to    
              A.remind you of where to have new shoes
              B.help you find the way of running that fits you
              C.take a rest between running days
              D.help you do some research on exercise
              65.The passage is written to    
              A.provide information for the researchers to work better
              B.warn the non-runners of the dangers in running
              C.help runners to exercise in a scientific way
              D.encourage as many people as possible to join in running.
            • 4. Teenagers believe anything is possible if thy study hard.But they often forget to think about healthy diets(饮食),enough sleep time and exercise.In fact,these things are really important for them to keep fit.
                It is important for teenagers to get enough energy.Teenage girls need about 2200 calories a day while boys need a bit more-doctors suggest 2800 for teenage boys 50% of their calories should come from healthy food-rice,begetables and fruit.People often say an apple a day keeps the doctor away.Teenagers also need to drink a lot of water,6 to 8 glasses a day.Drinking enough water will improve their skin.
                Teenagers usually need eight to ten hours'sleep at night,but many Chinese teenagers do not get enough sleep.A report shows that without a good night's sleep,teenagers seem to be weaker than they should be.Too much homework is not the only reason why teenagers stay up late.Some watch TV or play computer games late into the night.Teenagers should develop good study habits.So some clever students never study late,but they are able to work well in class.
                Exercise is something that can help them.Experts suggest that teenagers should spend at least 30 minutes exercising a day,five times a week.They will feel relaxed when they exerxise.It can even help them sleep better at night.

              B.rice,vegetables and meat 
              C.rice,vegetablesand water
              48.The last paragraph(段)mainly talks about    
              A.sleeping better      
              B.basic energy      
              C.necessary exercise

              B.Teenagers need to drink 6 to 8 glasses of water a day
              C.Some clever students never study late
              50.The passage tells teenagers how to    
              A.eat and drink well      
              B.study hard    
              C.keep fit.
            • 5. Being on vacation doesn’t mean that you should stop doing exercise.You must continue with the fitness(健康) programs if you want to keep fit.The following tips can help you continue with your fitness programs even while you are on the road.
              Packing for fitness.You should pack your sports things,such as sports shoes,sports DVDs,sports clothes and so on.Remember not to pack big things.You know you don’t have enough room to keep them during a trip.When you have packed all the fitness things,you can prepare to go.
              If you are staying in a hotel,you should find out if there are any sports facilities(设备) in it.For example,most hotels have swimming pools,so it’s a good idea to go swimming for some time in them.
              Perhaps walking is the easiest way of exercising that you can do during traveling.When you are on a train,you can put on your sports shoes and take a walk along the aisle(过道).It will help you do some exercise during those long trips.

            • 6. What are you going to do if you are in a burninghouse?How will you escape?Do you know how to save yourself?Please read the following passage.
              Escaping a fire is a serious matter.Knowing what to do during a fire can save yourself.It is important to know the ways you can use and to show them to everyone in the family,such as stairways(楼梯) and fire escapes,but not lifts.
              From the lower floors of the building,escaping through windows is possible,learn the best way of leaving through windows with the least chance of serious injury(伤害).
              The second floor windows are usually not very high from the ground.An average(普通的) person,hanging by the finger-tips will have a drop of about six feet to the ground.It is about the height of an average man.Of course,it is safer to jump a short way than to stay in a burning building.
              Windows are also useful when you are waiting for help.Be sure to keep the door closed,or smoke and fire may be drawn into the room.Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(渗入) into the room.
              On a second or third floor,the best windows for escaping are those which open onto a roof.From the roof a person can drop to the ground more safely,dropping onto stones might end in injury,bushes and grass can help to break a fall.

            • 7. Did you know that the noise in your school yard can harm your hearing seriously?
              During breaks at school,you find yourself in the middle of loud activities in the hallways and the school yard.You need breaks to have fun with your friends,but you should be careful as the noise at school can be dangerous to your hearing.
              Here are some examples of school yard noise:
              Climbing the jungle gym (at a distance of 25meters):70-100dB(分贝);
              Girl shouting (at a distance of 3meters):120dB;
              Boy shouting (at a distance of 3meters):I20-130dB;
              Students throwing a shovel (铁铲) on a wooden box (at a distance of 1meter):135dB
              Some factors (因素) decide how harmful a noise is to the human ear:the distance to the noise,the level of the noise and the time it lasts.
              We can stand noise at the level of 85dB for eight hours a day.But as the noise increases,we can only stand the noise for shorter and shorter periods of time.When the noise level reaches 115dB,our ears can stand it for less than 30seconds a day.Noise at the level of 130dB harms your hearing if you hear it for more than one single second a day.
              If you want to enjoy your breaks,you should help keeping the noise level down.

              58.From the passage,we know that     factors decide how harmful a noise is to the human ear.
              A.two   
              B.three    
              C.four    
              D.five
              59.Our hearing will not be harmed by noise    
              A.at the level of 85dB for 12hours a day
              B.at the level of 115dB for 20seconds a day
              C.at the level of 130dB for 5seconds a day
              D.at the level of 135dB for 3seconds a day
              60.What is the main idea of the passage?
              A.Noise at school can reach very high levels.
              B.There are many kinds of noise in the school yard.
              C.Students shouldn't have activities in the school yard.
              D.Noise at school can be very harmful to students'hearing.

              A small town named Bundanoon in Australia has decided to stop the sale of bottled water.The government says that bottled water can cause environment problems.After people drink the water,they throw the bottles everywhere.
              The government also encourages visitors to get water from water stations in the main streets,and fill the water in bottles that can be used again.All the shopkeepers in the town support the decision.Bundanoon is the world's first town that has got its shops to stop selling bottled water.Probably we should follow the example.Let's stop buying bottled water and use running water!
              Article 2
              People are busy these days and they have no time to cook.This becomes a problem,because most families love home cooking!The food tastes good and warm,and a family meal brings everyone together.In some families,meals are often the only times everyone sees one another at the same time.
              Another reason people enjoy home cooking is that it is often a way of showing love.A parent who makes some cookies is not just satisfying (满意) a child's sweet tooth.She or he is sending a message.The message says,“I care about you enough to spend an hour making cookies that you will eat up in fifteen minutes if I let you.“

            • 10. 阅读下面短文,从题中所给的A、B、C、D四个选项中选出最佳选项.
              Medical experts say most Americans do not get enough sleep.They say more Americans need to take a nap-that is to rest for a short period in the middle of the day.They give people advice to sleep lightly before continuing with other activities.The experts say naps might improve health by  reducing pressure.
              Some European and Latin American companies have supported the idea of napping for many years.They ask people to leave work,go home and have a nap before returning.In the United States,some companies let workers rest simply in their offices.They believe this can help workers make fewer mistakes and also increase the amount of work that a person can do.
              Sleep experts say it is likely that people make more mistakes at work than at other times.They say people should not carry out important tasks when they feel sleepy.And they say the best thing to do is to take a nap.About twenty minutes of rest is all you need.Experts say this provides extra energy and can increase your effects until the end of the day.But experts said that a nap should last no more than twenty to thirty minutes.A longer nap will put the body into deep sleep and waking up will be difficult.
