郑某,男性,22岁,大三学生 自我陈述:因紧张胆小怕见人6年。 16岁那年上初三,学习很紧张。在一次集体活动中抽到我表演节目,当时我心理就特别紧张,心脏好像快跳出来了似的,脸一下子发热,头皮和身体发麻,节目没表演好,同学们都在下面笑我,我当时真想逃跑。那时的情景我现在都记得非常清楚。从那以后,我就变得胆小,讲话都不敢大声,也很少与同学们一起活动,怕出洋相。课间休息时间我也很少离开座位,假装看书或做作业,其实我很想与他们一起玩,但没办法融入他们当中去。就这样艰难地上完初三,心想考入了高中后我会改变这种状况的,可是到了高中我还是不能放松自己,还是怕参加集体活动。上高一时,我心里爱上了一个女同学,但不敢接近她,也不敢与她讲话,见到她我就脸红,眼光不知往哪里看,浑身上下很不自在,慢慢地连别的女同学我都不敢正面看了,也很少与男同学来往了,他们都觉得我怪怪的。考入大学后,自由支配的时间比较多,周末同学们都三五成群的外出活动,可我从来就没有那样的生活。我在大学里都是独来独往,简直就像个幽灵似的怕见人,没有一个知心朋友,也没有人愿意和我一起玩。我要么最早去教室上课,要么就干脆不去;下课后我也是最后一个回寝室,因为怕在路上碰到别人,万一碰到我也是低头走过的,我从来就不敢正面看别人,我怕我的眼神会使别人不自在不舒服;我很痛苦很自卑很敏感,有时同学们在那边说话,我也会想他们是不是在说我不好,我知道是由于自己太敏感的原因,但我当时会表现得很不自在。我希望能给别人留下好印象,希望别人都喜欢我,可做不到。快要毕业面临找工作了,我这样一种状况怎么办,我实在太痛苦了,请心理咨询师一定要帮帮我。 心理测验: 在评估该求助者心理行为的认知因素时,需要注意的因素有()。
A.来自童年的固定信念 B.存在的智力缺陷 C.既往生活中的挫折与痛苦经历 D.负性自动思维

TEXT A Are organically grown foods the best food choices The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods frequently proclaim that such products are safer and more nutritious than others. The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the greater number of written material advancing such claims make it difficult for the general public to sep arate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore. Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that crops grown with organic fertilizers are nutritionally superior to chose with chemical fertilizers, that untreated grains are better than fumigated grains, and the like. One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern ff consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
