不复杂的

The causes to these features are complex,which mainly include:1.the sudden change of the learning surroundings;2.the perplexity of the emotion toward specialty;3.the side-effect of the learning and managing patterns which are left over the from the middle-school;4.the influence of the social factors;5.the impromptus in the instruction from the university.

形成这些特点的原因是复杂的，主要有：1、学习环境骤变；2、专业情绪困扰；3、中学阶段学习方式和管理方式产生的负效应；4、社会因素的影响；5、学校教育引导不及时。
