Basically you can do nothing.Your genes，not your life habits，determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that“80 percent of the children of two fat parents become fat，as compared with no more than 14.percent of the children of two parents of normal weight.”   
How can obese people become thinner through dieting? Well，dieting can be effective.but the health costs are great.
Jules Hirsch，a research physician at Rockefeller University，did a study of eight fat people.They were.given a liquid formula（配方）providing 600 calories a day.After more than 10 weeks，the subjects lost on average 45 kg.But after leaving the hospital，they all regained the weight.
The results were surprising：by metabolic（新陈代谢的）measurement，fat people who lost large amounts of weight seemed like they were starving.They had psychiatric problems.They dreamed of food or of breaking their diet They were anxious and depressed.Some wanted to kill themselves.They hid food in their rooms.
Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormal state lust like that of starved non.obese people.   
Thin people, however，suffer from the opposite.They have to make a great effort to gain weight  Ethan Sims of the University of Vermont got prisoners to volunteer to gain weight.In four to six months—they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended，they were back to normal weight and stayed there.
This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance（遗传）if they want to significantly 1ower their weight.
The findings also provide evidence for something scientists thought was true—each person has a comfortable weight range.The range might be as much as 9kg.Someone might weigh 60--69kg without too much effort.But，going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing.the metabolism to push the weight back to the range it seeks.

    ARK(Absolute Return for Kids)works with seven Home-Start centres across the UK to provide understanding，trained volunteers to support problem families．Through this early intervention(干预、介入)we aim to solve child and family problems before they become so intractable that social service intervention is required．

    Problem families in the UK often receive too little assistance too late．Low social service capacity(能力)means families often reach breaking point before receiving any support．Social workers have little time to build trust with the family and develop all understanding of specific problems．What is more，social workers can be regarded by families as a threat一“They come to take our children away”．

    Parents(with children under five)who suffer from illness，disability，addiction，poverty or other pressures receive visits from a trained volunteer one afternoon a week to support and advise them through period of crisis．Where possible the volunteer comes from a similar background to the people calling for help，or has personal experience of similar problems．

    The effectiveness of Home-Start's longstanding programme has been proved by a number of research reports．One study of problem families assisted by Home-Start volunteers found：

    ·Nearly 40％ of surveyed mothers reported reduced depression．

    ·42％ of families reported improvements in managing their children．

    ·Child behavioral problems reduced by 50％．

    Since ARK’s involvement this success has been recognized in the Government’s Green Paper Every Child Matters．The paper recommended enlarging the programme to ensure Home-Start services are available in every community in the UK．The Government has now provided￡5 million to help Home-Start achieve this goal．

1．The main purpose of ARK’s work with Home-Start is to ______．

      A．train volunteers to support problem families

      B．build good relationship with the problem families

      C．solve child and family problems at the beginning

      D．save every problem child in place of social services

2．The underlined word “intractable”(in Paragraph 1)most probably means _____．

      A．serious             B．particular          C．attractive          D．sensitive

3．It can be inferred from the passage that __________．

      A．the UK government can usually help problem families in time

      B．social workers enjoy high popularity among problem families

      C．the volunteers must share the same background with the people needing help

      D．social service can’t satisfy the needs of problem families

4．In the UK，Home-Start services are now _______．

      A．spread to every corner                    B．proved to be effective

      C．thought of as a threat        D．run by the government

China’s Ministry of Culture has recommended 10 cyber games(网络游戏) that are suitable for minors to play as part of its drive to purify the on-line environment for the young.
The 10 cyber games were selected by the ministry’s on-line games censorship committee from scores of games recommended by the Chinese public.l
The games are all domestic products. They include five role playing games (RPG), four recreation and chess games, and one educational game, such as “Warring States Ⅱ Online,” “Rainbow Island Online,” and “Wonderlands of learning and games.”
These games have made their way into the final recommendation list because they are considered “healthy” and can “enhance intelligence,” according to the ministry.
The ministry hoped the list could serve a a guidance for parents to better direct their children in the winter vacation, which usually lasts nearly two months from January to February each year.
This was the third time for the ministry to publish recommended cyber games list. The previous two were made public respectively in January 2006 and August 2005 with a total of 25 games inlisted.
In the past few years, on- line games have become the favorite pastime of young people. However, it is argued that such social problems as game addiction, juvenile delinquency (青少年犯罪) and perversion among minors by on-line violence and pornography (色情) have come from an inadequately regulated Internet.
About 9.72 percent of Chinese netizens between the ages of 13 and 30 suffer Internet addiction, said a report issued last month by the China Youth Association for Network Development (CYAND).
According to the China Internet Network Information Center (CINIC), the main Internet watchdog, China had 210million Internet users at the end of 2007 and its online population is on course to become the world’s largest at the beginning of this year.
Net users between 18 and 30 accounted for 49.9percent of the total users. Although the CINIC did not give the figure of those below 18, teenagers and youths have obviously taken up more than half of the total number of net users. And the number of users under age 18 increased rapidly last year, the CINIC noted.
