Thomas Alva Edison was awarded more patents on inventions than any other American.
When he died in l931，Americans wondered how they could best show their respect for him.
One suggestion was that the nation observe a minute or two of total black-out.All electric power would be shut off in homes streets and factories.
Perhaps this suggestion made Americans realize fully what Edison and his inventions
meant to them.Electric power was too important to the country.Shutting it off for even a short time would have led to complete confusion.A black—out was out of the question.
On the day of Edison's funeral，many people silently dimmed their lights.In this way they honored the man who had done mroe than anyone else to put the great force of electricity at his countrymen's fingertips.

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(卡路裏)：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).
A.think exercise helps people's bodies work against them
B.agree exercise helps to lower people's weight
C.bilieve in exercise at all
D.think exercise helps people's bodies work with them
41.Exercise helps you________.
A.save calories and gain weight
B.save calories but lose weight
C.bum calories and lose weight
D.burn calories but gain weight
42.When you walk________.
A.slowly，the fat in your body increases
B.1ess，you build more muscles
C.faster，you bum less calories
D.fast，the fat in your body reduces
43.Which of the following is NOT true?
A.A man of more muscles burns calories faster.
B.Exercise speeds up your metabolism even after it.
C.An hour and a halls exercise is not enough to keep your“setpoint”lowered.
D.To lose more than 5 pounds，just doing exercise is not enough.

One of the villagers thought he would be very clever.“If I pour a bottle of water in.instead of wine.No one will notice it，”he said to himself.“because there will be so much excellent wine in the barrel that the water will be lost in it.”

Like everyone else working at the Limerick nuclear-power(核能)plant，Stanley Watras had to pass through the monitors(監測器)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.
Neither Watras nor his co-workers could understand where he was picking it up.
Then one day Watras went through the door at Limerick and turned and walked back through the monitors without ever entering the power block.Yet the machines still said he was carrying radiation.“If I wasn’t picking up radiation at work,there was only one place it could be coming from：my house.”
When scientists came to test the Watrases’home in the countryside，they found out what was the matter.The house contained so much radon(氡)that living in it for a year was like being exposed(暴露)to 260，000 chest X-rays.In the year the Watrases had spent there，they had increased their chances of getting lung cancer(癌症)by 13 or 14 percent.
The next day the Watrases took down their Christmas tree，put their clothes in some bags and moved into a nearby hotel.“It was terrible，”says Watras.
The owner of the Limerick plant took charge of dealing with the Watrases’radon problem as an experiment.Scientists studied every comer of the house.When the ground was dug up，they found that under the house there was a uranium(鈾)-beating rock.

答案：Today pollution has become a serious international problem.Our air，seas，rivers and land have been polluted by waste or poisonous things.Pollution does great harm not only to human beings but also to animals and plants.We can't have fresh air because many factories have poisonous smoke sent into the air and the cars give off waste gasses.We can't have clean water because factories have pumped their waste water into rivers，lakes and seas.It is said that strange diseases have appeared in some places because of pollution.I think the government can do something to stop pollution. For instance，it can reduce the production of cars and encourage to produce environment-friendly cars.The waste and waste water from factories must be treated properly before they are sent out.In this way we can improve our environment and live a healthier and happier life.
