14.Each of us can live strong,healthy,energetic lives for a long time to come.The key?Actually,there are many of them.
Eat fewer calories,but more food
Slimming down can help prevent disease,and cutting way back on the amount you eat may even slow the aging process.When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health:Pile your plate high with vegetables and fruits,add respectable parts of beans and whole grains,and ignore high-calorie food like cheeseburgers,cream sauces,and fatty meats.
Use exercise as an anti-aging vaccine
Exercise can help you gain a better quality of life as you age.It's no secret that physical activity strengthens muscles,burn calories,and puts a happy bounce in your step.But recently,researchers discovered a new,extra benefit:Exercise acts as a powerful way against the aging process itself.When exercise physiologists put healthy people aged 60to 85on Weight-training programs for six months then tested them for signs of free-radical(自由基) damage,they were surprised by the results.By the end of the study,low-intensity exercisers had a drop in free-radical damage,while high-intensity exercisers had a slight increase.
Find something interesting to do
Life is always busy no matter what your age.But the truth is,when people are retired,time usually does become more available for adults after 60.With this time come choices.The easy one is merely to relax:watch more TV,eat out more often,talk on the phone as much as you want.The better choice?Discover something more meaningful to devote yourself to and do it wholeheartedly.

点评 1、要想做好科普英语阅读理解题,同学们就要注意平时多读科普知识类文章,学习科普知识,积累常见的科普词汇,从根本上提高科普英语的阅读能力.
2、要熟悉科普类文章的结构特点.科普类文章一般由标题(Head line),导语(Introduction),背景(Back ground),主体(Main body)和结尾(End)五部分构成.标题是文章中心思想高度而又精辟的概括,但根据历年的高考情况来看,这类阅读理解材料一般不给标题,而要同学们选择标题.导语一般位于整篇文章的首段.背景交待一个事实的起因.主体则对导语概括的事实进行详细叙述,这一部分命题往往最多,因此,阅读时,同学们要把这部分作为重点.结尾往往也是中心思想的概括,并与导语相呼应,命题者常在此要设计一道推理判断题.  
3、在进行推理判断时,同学们一定要以阅读材料所提供的科学事实为依据,同时所得出的结论还应符合基本的科普常识.

19.An emperor was almost eighty years old and knew it was time to choose his successor(接班人).Instead of choosing one of his children,he decided on something different.He called all of the young people in the kingdom together one day.He said,"It is time for me to choose the next emperor.I have decided to choose one of you."
The kids were shocked!But the emperor continued,"I am going to give each one of you a seed today.One special seed.I want you to plant it and come back one year later with what you have grown from this seed.I will then judge the plants,and the one I choose will be the next emperor!"
One boy named Ling received a seed like the others.He went home and planted the seed in a pot,watering it carefully.Every day he would water it and watch to see if it had grown.After about three weeks,some of the other youths began to talk about their plants that were beginning to grow.Ling kept checking his seed,but nothing ever grew.
A year finally went by and all the youths brought their plants to the emperor.Ling thought he should be honest about what had happened.So he took his empty pot to the palace.When Ling arrived,he was amazed at the plants grown by other youths.They were beautiful,in all shapes and sizes.
When the emperor arrived,he surveyed the room and greeted the young people.Ling just tried to hide in the back.Suddenly,the emperor spotted Ling at the back of the room with his empty pot.He ordered his guards to bring him to the front.Ling was terrified.When Ling got to the front,the Emperor asked his name."My name is Ling,"he replied.All the kids were laughing and making fun of him.The emperor asked everyone to quiet down.He looked at Ling,and then announced to the crowd,"Behold your new emperor!His name is Ling!"Then the emperor said,"One year ago today,I gave you all boiled seeds which would not grow.

6.Do you like shopping?Or does the thought of wandering round the shops fill you with terror?For some of us,shopping is an enjoyable way of spending our spare time and our money.For me.it's something I would rather avoid.Thank goodness for the Internet!It's more convenient to buy CDs,electrical items,even food,from the comfort of your sofa.But that's not the only reason:price is an important factor.We can buy goods and services cheaper online.But sometimes the problem is knowing what to buy.This has led to a type of shopping called"showrooming".
Showrooming is something I've done.I will go to a shop to see,touch and try out products but then go home and buy them online at a knock-down price.I'm not alone in doing this.Research by a company called Foolproof,found 24%of people showroomed while Christmas shopping in 2013.
Amy Cashman,Head of Technology at TNS UK,says the reasons for this new shopping habit are that"people are lacking time,lacking money and they want security about the products they are buying."She explains that consumers are not only shopping online at home but they are using the Internet in store or on their smartphones to shop around.
But does this mean technology will kill shops?Certainly shops will change.They will have to offer more competitive prices or encourage people to buy more by giving in-store discounts or free girls.
We mustn't forget that buying in a shop means you can get expert advice from the sales assistant and you can get good aftercare.It's good to speak to a real human rather than look at a faceless computer screen but at least by showrooming,you get the best of both worlds!
