| 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 so-called 'non-intelligence factors' include 1 feelings, will, motivation, interests and habits. After a 30-year follow-up study of 8000 males, American psychologists (心理学家) 2 that the main cause of disparities (不同) in intelligence is not intelligence 3 , but non-intelligence factors including the desire to learn, will power and self-confidence. 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, such as 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 hopeless. Others may go astray (迷途) because they are sick of learning. 11 investigation of more than 1,000 middle school students in Shanghai showed that 46.5 per cent of them were 12 of learning, because of examinations. 36.4 per cent lacked persistence, initiative (主动) and consciousness (知觉) and 10.3 per cent were sick of learning. It is clear 13 the lack of cultivation (培养) of non-intelligence factors has been a main 14 to intelligence development in teenagers. It even causes an imbalance between physiological (生理的)and 15 development among a few students. If we don't start now to 16 the cultivation of non-intelligence factors , it will not only affect the development of the 17 of teenagers , but also affect the quality of a whole generation . Some experts have put forward 18 about how to cultivate students' non-intelligence factors. First, parents and teachers should 19 understand teenage psychology. On this basis, they can help them to pursue the objectives of learning, 20 their interests and toughening their willpower. | |||
