The world would be a better place if we all had children’s eyes. This is not because children’s eyes are too sharp to allow any blot（污点，瑕疵）to pass without being      , but because adults have too many conflicting concerns to keep their eyes open to all wrongdoing.
Not long before, an examination, intended to      some police officers to higher positions, was held in Gansu province. Someone      with a good idea that 18 primary pupils could be invited to act as invigilators (监考人). At that age, students would do as they are told and act fearlessly.       , they caught 25 officers cheating on the spot, which has caused a stir (轰动，搅动) and       the question of whether adult invigilators would       their duties as well.
The implication of this event goes       its impact on the work style of local police officers and the examinations. Most people said what these children have done points to the sad fact of       being less trustworthy. If adults acted as invigilators, they would quite       turn a blind eye to cheating.
We Chinese have been holding the       that human nature was good at birth: as       of blot as a sheet of blank paper, which can be       with content (good or bad) in the process of growing up. Everything should be done on the basis of certain principles(原则).       , nowadays the repeated reports of cheating in examinations, selling ranks and       and embezzling (挪用) public funds paint a       picture of common social morals.    Adults have become too concerned with their own personal gains to       basic sense of principles. When no one       any principle and the only concern is personal interest, everyone will       , not only those who first break the rules.
Besides, cheats are unfair to honest examinees, and when the success of cheats       more people to cheat, the consequences will be disastrous.
In a word, we adults need to have our eyes as       as children’s on matters of principle.
