    12．Which comes first，happiness or money？Are richer people happier？And if so，how do people get much richer？A recent study could tell you the answer．
    The study looked into thousands of teenagers and found that those who felt better about life as young adults tended to have higher incomes by the time they turned 29．Those who were happiest earned an average of $8，000 more than those who were the most depressed．
    The researchers，from University College London and the University of Warwick，say that very gloomy teens，no matter how tall or smart they were，earned 10% less than their peers，while the happier ones earned up to 30% more．
    Happier teenagers have an easier time getting through school，college and the job interview，chiefly because they always feel better about life．It may also be true that happier people find it easier to make friends，who are often the key to homework help or networking．
    A report in June suggested that professional respect was more important than dollars in terms of workplace happiness．In August scientists announced that they had found the gene for happiness in women，Alas （the same gene doesn't appear to have the same effect on men）．And in October researchers in the UK and in the US announced that people who eat seven portions of fruit and vegetables a day report being the happiest．
    The big question is：if it is really true that happier kids end up being wealthier kids，is it necessary for parents to get their kids to do the homework？The fact is that no homework will make kids happy but surely hurt their grades．Studies do show，after all，that more education leads to betterpaid jobs，which may give us a deep thought．
    "These findings show that the teenagers'happiness is important to their future success，"one of the report's authors writes．"But what is the most important is that we should find a way to help children gain more satisfaction from doing schoolwork．"

    28．What conclusion can the researchers draw from the recent study？A
       A．Happy teenagers grow up to be wealthier．
       B．Money can make people become happier．
       C．Wealth has nothing to do with happiness at all．
       D．Schoolwork can help teens achieve success．
    29．The main reason why happier people have more chances to succeed is thatC．
       A．they are easy to communicate with others
       B．they are good at doing their schoolwork
       C．they are hopeful and optimistic about their life
       D．they eat much more fruit and vegetables a day
    30．The underlined word"gloomy"in Paragraph 3 probably means"A"．
       A．upset            B．glorious              C．happy             D．wealthy
    31．What can be the best title for the text？D
       A．The way to educate kids．           B．The source of happiness．
       C．How to achieve your goal            D．The secret of being wealthier．

    If you feel tired，out of shape，or sad，most of the time，making friends is going to be extremely difficult．（38）GStart small．Use the l-minute technique to gradually increase your commitment to exercise．Get out into nature．Set a timer to remind yourself to get up every hour to stretch．Try gentle yoga．

    Decide on a topic．（36）E If you plan to write a news article for a monthly newspaper，you will need to take into consideration whether the topic will be relevant before printing．To get ideas for stories，listen to your fellow students and find out what has them talking．Follow developments within your school and community to get information on what would interest your readers．

    Attract the readers with a lead．As the beginning of a newspaper story，a lead has to be direct，but it does not mean you don't need to entertain the reader as well．（38）C Your lead must be short，but it must also state as many of the essential parts of you story as possible．
    Consider the 5Ws and H．These are the meat and potatoes of your news articles．You article must answer all of these questions：Who，What，When，Where，Why and How．Once you have answered these things，you can feel confident．（39）B．
    Write，edit，rewrite and repeat as necessary．So，much about having a successful final product is about being willing to spend time and effort in editing and reviewing process．（40）D After that，make changes as a result．Having taken some useful suggestions，you are to make your article readable not only for their content，but also for their quality．

    A．Think about what is happening on campus．
    B．You have effectively informed your readers．
    C．Get them interested with an interesting beginning．
    D．Do not be afraid to accept positive comments．
    E．News articles are suitable for the date of publication．
