When he died in l931，Americans wondered how they could best　show their respect for him.

The human body naturally prevents attempt( 企 圖 )to lose or gain　　weight.Thus the best way to lower your weight is to do some exercise　daily.Although scientists don’t agree exactly　how this works to lower the“setpoint”，they do know that exercise　helps your body work with you and not against you in at least the

following ways：

1.Exercise burns calories(卡路里)：if you walk two miles every day，　you use an extra 1400 calories a week—and lose about a pound in two　weeks.

2.Exercise helps to bum fat and build muscle：since muscle requires　more calories than fat does，the more muscle you have，the faster you　will bum calories.

3.Finally exercise speeds up your metabolism(新陳代謝)，not just　while you’re exercising，but for several hours after exercise ends.

A program of light-to-moderate exercise done for only a half-hour a　day is enough to keep your“setpoint”lowered，and thus helps you lose　　weight and keep it off.If you need to lose more than five pounds ，combine regular exercise with a moderate reduction in calories until you　reach your goal(目標).

Like everyone else working at the Limerick nuclear-power( 核能)plant，Stanley Watras had to pass through the monitors(監(jiān)測器)before　　leaving the buildin9.Most of his co-workers.passed through without a　problem，but Watras，an engineer，continually set off alarms(警報).Some　days he was found to be carrying six times more radiation(輻射物)than　normal.
