When I was a law professor, a student reported that I made an error in grading his exam by giving him too many points．He was 41 and after thanking him for his honesty, I changed the grade in my  42  . His beaming(欢笑的）face turned to shock．"You're  43  my grade?" he said angrily．"I would never have come in  44  …"

He didn't finish the  45_ , but it was obvious that his display of honesty was  46_ .He thought he'd have it all —praise and the higher grade．

Several colleagues thought I should have let the higher grade 47  because all I'd accomplished was to discourage him from being  48 in the future．And every time I tell this story, some people agree to this   49 ．

But I can't see how I could give good reason for worsening my_ 50  in grading by undermining(损害） the honesty of all my grades by failing to  51 an error．The grade itself would be a dishonest  52  of his knowledge and it would have been 53 to other students．How could I  54 give a student a gift of an unearned grade?

I know 55 reporting an error in one's favor is unusual, but, like 56_ too much change, it's clearly the right thing to do．People of character, those with real honesty, hate to give up  57 as much as anyone else．The difference is that for them a good conscience and reputation is  58 

enough to give reason for the cost of doing the right thing．

Perhaps lowering the student's grade did  59 him from being honest in the future, but bribing（贿赂）him to be honest so that he does the right thing when its cost-free would have   60 him even more．The duty to be honest is about right and wrong, not risks and rewards．

In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by an environmental protection organisation，which has contributed to improving the living environment for wild animals. Recently, the organisation has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.

In the area, the local people have planted many special flowers with the help of the organisation, aiming to see whether these flowers will interest the rare and beautiful butterflies. The Project officer Sarah Marshall says, “It will be a suitable habitat for butterflies. They are great ‘indicator species’ as they are easily affected by climate changes so they make a brillian early - warning system for the environment.” She also points out that volunteers are needed to recourd the number or species of butterflies，and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.

The organisation is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way.Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit（butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.

No previous experience is necessary as training and support will be provided，but a keen interest is essential. If you are interested, P1ease contact Sarah on (0l380) 725670，ext 278, email sarahm wiltshirewildlife. org
