     Some personal characteristics play an important role in the development of one's intelligence. But
people fail to realize the importance of training these factors in young people. The socalled
nonintelligence factors'(非智力因素)include __1__ feelings, will,  motivation, interests and habits.
After a 30year followup study of 8000 males, American psychologists __2__ that the main cause of
disparities in intelligence is not intelligence __3__, but nonintelligence factors including the desire to
learn, will power and selfconfidence.
     __ 4__ people all know that one should have definite objectives, a strong will and good learning
habits, quite a number of teachers and parents don't pay much attention to __5__ these factors. Some
parents are greatly worried __6__ their children fail to do well in their studies. They blame either genetic
factors, malnutrition(营养不良)or laziness, but they never take __7__ consideration these
non-intelligence factors. At the same time, some teachers don't inquire into these reasons __8__ students
do poorly. They simply give them more courses and exercises,  or __9__ criticize or laugh at them. After
all, these students lose self-confidence. Some of them just feel defeated and __10__ themselves up as

to __14__development in teenagers. It even causes an imbalance between physiological and __15__
development among a few students. If we don't start now to __16__ the improvement of nonintelligence
factors, it will not only affect the development of the intelligence of teenagers,  but also affect the__17__
of a whole generation. Some experts have put forward __18__ about how to improve students'
