5．
1．Exercise
Studies show that 30minutes of mild exercise a day will increase your life span．This doesn't mean you have to run three miles or start jumping．Simple activities such as walking，gardening or taking exercise classes will work．
2．Enjoy people
Contacts with family and friends help fight life-sapping depression and stress．Studies show that people socialize regularly live longer than loners．Interact daily with family members and friends．If you are isolated，make a point of joining social clubs or church groups so you can laugh and share life's joys．
3．Stay mentally active
This is very important-use it or lose it!People who allow their mental faculties to decline run the risk of shortening their lives through falls and other injuries，and not being able to take care of themselves．Read the newspaper，visit the public library，balance your checkbook without a calculator，and exercise your brain by doing crossword puzzle．
4．Diet
The key words are"high-fiber，low-fat"．Cut back on red meat，salt，white flour，white sugar，alcohol and coffee．Start eating a balanced diet including lots of fruit，grains，raw vegetables and nuts．
5．Positive attitude
By approaching life with a positive outlook you increase your chances of living longer．Stay optimistic-always search for the silver lining．Studies show people who see life as an enjoyable challenge，rather than a constant trial，cope better and prolong their life spans．
6．medication mix
As we age，we are more likely to take medications．Sometimes this leads to over-medication，which can be disabling and even deadly．Ask your doctor if the drugs you take are really necessary．Make sure there is no danger of a bad drug interaction from your medication．Used correctly，medicines can help you live longer and more comfortably．
7．Volunteer
Helping others increases your self-esteem and makes you feel like a valuable contributor．

66．Which of the following does NOT increase your life span？B
A．Staying happy about life                     B．Exercising as much as possible
C．Exercising your brain frequently             D．Enjoying your social life
67．People who do not stay mentally active are more likely toC．
A．become ignorant                             B．lose their minds
C．shorten their lives                         D．become slow in movement
68．The underlined phrase silver lining can be replaced withC．
A．something made of silver                   B．new information
C．good aspects                               D．long life span
69．Which of the following is correct about medication？A
A．Appropriate medication is necessary．
B．Medication is always helpful to you．
C．Doctors suggest taking expensive medicines．
D．Drugs are unnecessary because of side-effects．

3．A glass a day keeps obesity at bay．Alcohol has always been thought to cause weight gain because of its high sugar content，but new research suggests a glass a day could form part of a diet．Looking at past studies they found that，while heavy drinkers do put on weight，those who drink in moderation can actually lose weight．
A spokesman for the research team at Navarro University in Spain says，"Light to moderate alcohol intake，especially of wine，may be more likely to protect against，rather than promote，weight gain"．The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions，particularly that current data do not clearly indicate if moderate drinking increases weight．
Boston University's Dr．Harvey Finkel found that the biologic mechanisms（生物學(xué)機(jī)制） relating alcohol to changes in body weight are not properly understood．His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes（糖尿病），which relate to increasing obesity．Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers．
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat，and that this process could explain the differences in its effects from those of other foods．They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks，taking into consideration drinking patterns and including the past tendency of participants to gain weight．
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one's risk of becoming obese．What's more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine，destroys fat cells．

66．The passage is mainly for thoseD．
A．who produce wine                     
B．who are eager to lose weight
C．who go on a diet                      
D．who have a drinking habit
67．The underlined phrase"in moderation"in the first paragraph meansA．
A．properly          
B．carefully         
C．excitedly          
D．frequently
68．Why has alcohol been thought to cause weight gain？B
A．Because its calories are stored in fat．
B．Because it is rich in sugar．
C．Because it changes drinking patterns．
D．Because it increases the risk of diabetes．
69．What can we learn from the passage？C
A．The specific roles of different types of alcoholic drinks are very clear．
B．Resveratrol is proved to increase the risk of becoming fat．
C．The research found moderate drinking has a strong protective effect．
D．Current data clearly show that moderate drinking increases weight．
70．What is most likely to be discussed in the paragraph that follows？B
A．How to do some easy experiments．
B．How to prove the finding mentioned above．
C．How to make wine in a healthy way．
D．How to reduce the calories contained in wine．

10．Many people focus on physical fitness，but few know that brain fitness is also something you can work on．In fact，you can exercise your brain as often as you work out your arms or abs--and the results can be positive and empowering．It's helpful to think of your brain as you work out a muscle．To improve your brain，you can't simply repeat the same exercises over and over．Just as lifting a two pound weight will no longer challenge you，so will repetitive exercises such as crosswords or Sudoku．Once you master easy exercises，you must move on to harder ones in order to push your brain-like your muscles-to a new level．
Scientists once believed that your mental abilities were fixed in adulthood．Now that studies on neuroplasticity have shown just the opposite，millions of people around the world have adopted the new practice of brain training．
The most popular of these brain training products is made by the San Francisco-based Lumosity，which employs a team of in-house neuroscientists with degrees from Stanford and UC Berkeley．Realizing that brains need more sophisticated programs and guidance to grow and change，Lumosity's scientists work with an experienced team of game designers．Together they've developed a fun，effective online brain training program that measures，tracks，and adapts to your progress so you'll always be challenged．Lumosity's training system and 40+games are based on well-studied tests used in clinical neuropsychology research．
In a 2013 Stanford study，a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed，mental flexibility，and working memory tasks．On average，those who trained improved on tests of these abilities，compared to a group that did not train with Lumosity．There is even some first round evidence suggesting that Lumosity may be beneficial to normal，healthy adults．In a 2011 study by Lumosity and San Francisco State University researchers，13 people who did Lumosity training over 5 weeks improved on tests of brain performance compared to a group that did not train．On average，those who trained improved working memory scores by 10% and attention scores by 20%．
Training can take just a few minutes a day，but the rewards can make a difference in many aspects of life．The goal of brain training is not to improve game scores：it's to improve the underlying core abilities that those games rely on．Lumosity is one of the first and most popular brain training programs in existence．There's a small fee to use the full product，or new users can start a free trial．
66．What is the best title for the passage？A
A．Brain training can make a difference
B．Brain training-a new science．
C．Brain training can keep you fit
D．Brain training-an open online course．
67．In order to improve our brain，we canB．
A．do the same exercises day after day                      
B．challenge it with harder exercises day by day
C．work out crosswords every day                      
D．a(chǎn)dapt to physical change
68．According to the passage，what is Lumosity？C
A．It is a team of in-house neuroscientists
B．It is a team of experienced game designers．
C．It is an online brain training program
D．It is a clinical brain training research．
69．In Paragraph 4，the writer gives so many figures toD．
A．explain the cause of Lumosity                                  
B．clarify the principle of Lumosity
C．confirm the process of Lumosity                              
D．show the effect of Lumosity
70．It seems to us that the passage is exactlyA．

6．All of us should keep a kitchen diary，showing how much food are left uneaten as garbage．
We all waste food，you and me millions of tons of it．In China，enough food is wasted in restaurants every year to feed 200million people．In the United States，40percent of food is wasted from farm to fork．Each year，the amount of food thrown away in rich countries is almost the same as that produced in sub-Saharan Africa．This raises some important questions．
In developing countries，food is lost because farmers do not have appropriate cooling，storage or market access for their crops．Their grains，fruits and vegetables dry up and rot away．In developed countries，the picture is different，and food is wasted in supermarkets，restaurants and at home．China faces both problems，significant losses in farms，as well as at the sale and consumption stages．And the amount of food wasted by Chinese consumers is rapidly increasing．
Consumer culture has filled China and urban residents can get quality food from anywhere in the country and from across the planet．Chinese consumers are as particular about their food as those in other countries．In supermarkets，they refuse to buy vegetables that don't look fresh or have an irregular shape，or milk and other products close to their expiry （失�。� date．
Besides，Chinese consumers tend to be generous．In restaurants or at home，often too much food is ordered or cooked and served．So while trooping out of a restaurant，full and happy，with colleagues or friends，they never look back at what's left untouched on the table．Should Chinese consumers take more responsibility for the waste they create？
Everyone deserves to have enough food to eat．Despite China's impressive success in reducing hunger over the past three decades，the job is not completed yet．

31．According to paragraph 1，we know that food waste isA．
A．huge worldwide
B．mainly in USA
C．only in rich countries
D．just in African countries
32．In developing countries，food is lost mainlyA．
A．for the lack of cooling and storage
B．because of easy access to markets
C．because of the wet weather
D．because of the quality of the food
33．The main reason for food waste in China isA．
A．the effect of consumer culture
B．the convenient food supply
C．the worry about food quality
D．people's being particular about it
34．How do Chinese feel when they leave restaurants with much food left behind？A
A．Generous．
B．Unconscious．
C．Wealthy．
D．Valuable．
35．The purpose of the passage is to tell usA．
A．not to waste any food from now on
B．the necessity to improve food quality
C．the fact of food waste in developed countries
D．the influence of consumer culture on Chinese．
