问题 Clive：
    The risk of having a heart attack on any given day should be one in seven, but a six-year study coordinated by researchers at the Free University of Berlin of more than 2,600 Germans revealed that average person had a 20 percent higher chance of having aheart attack on aMondaythan on any other day．
    Pamela：
    Working Germans tend to be influenced particularly,with a 33 percent higher risk at the beginning of the working week．Non—workers，by comparison, appear to be no more at risk on a Monday than any other day．
    Otis：
    The findings could lead to a better understanding of what triggers heart attacks,  according to Dr．Stefan Willich of the Free University．"We know a lot about long- term risk factors such as smoking and cholesterol but we don’t know what actually triggers heart attacks, so we can’t make specific recommendations about how to prevent that", he said．
    Kent：
    Monday morning have a double helping of stress for the working body as it makes a rapid transition from sleep to activity, and from the relaxing weekend to the pressures
of work．"When people get up，their blood pressure and heart rate go up and there are hormonal changes in their bodies,"Willich explained．"All these things can have a negative effect on the blood system which will cause a heart attack．"When people return to work after a weekend off,the pace of their life changes．They have a higher workload，more stress, more anger and more physical activity, said Willich，"We need to know how these events cause changes in the body before we can understand if they cause heart attack．"
    Ida：
    Although it is trying to believe that returning to work increases the risk of a heart attack, both Willich and the Italian researchers admit that it is only a partial answer． Both studies show that the over-65s are also to be unprotected in a Monday morning even though most no longer work．The reason for this is not clear, but the Italian team at Liugui Saddo Hospital in Milan thinks over the social interactions—the thought of facing another week and all its pressures—may play a part．
    Note：thereare two extra statements．
         Statements
[A]There are many reasons for heart attacks．
[B]Mondays are really riskier than food and way of life．
[C]Monday morning feeling is terrible for somebody．
[D]Occasionally, joblessness is safer than employment．
[E]Aged people also tend to suffer heart diseases．
[F]The steps of reducing heart attack are given．
[G] Mtering the schedule may result in heart attack．
