杨某，女性，18岁，某大学一年级学生，未婚自我陈述：我从来就性格孤僻，没有伙伴，甚至和弟弟也不接触，当时并不觉得这是什么缺陷。上初中以后看到其他女同学经常同男同学在一块儿又说又笑，十分开心，对他们既羡慕又嫉妒，自己为什么就做不到呢，我虽然个性孤僻但内心却渴望与人交往并希望被他们重视，可我又做不到，同学们很少和我交谈，因此我内心矛盾重重。进入高中这种内心矛盾越发强烈，每天独来独往十分痛苦。高三后期几乎不敢去上课，在家看书还能勉强静得下来，一到学校就心烦意乱，由于过去基础很好考大学时才没有落榜，进大学以后又产生一种自卑感，总感到自己不如别人，有一次考试时，一位男同学问我一道题的答案，我很高兴地告诉了他，但被监考老师发现并说"有些同学眉来眼去地干什么"。我听后十分害怕，总感觉自己眼神不正常，不敢和别人对视，总怕别人说我不正经，怕同学耻笑，有时不敢去上课，不敢与同学往来，怕与别人的视线相对，说自己不正经。我父母都是大学教授，事业心较强，一心想在教学科研方面出点成绩，对学生很有耐心，帮助和辅导他们争取学有所成，但对自己的孩子却很少过问，更不用说彼此谈心了。我有一个小我一岁的弟弟，正在读高中，我们也很少在一起聊天。父母不注重管理家务，家里非常零乱，吃穿方面更不讲究，我穿的都是父母的旧衣服改制的衣服，我总觉得不如别人，在男同学面前没有吸引力。了解资料：父母介绍：求助者自幼胆小，不敢单独一个人在家，不敢和同学来往，不敢单独出去做事，自进入大学后连上课也不敢抬头看老师讲课。夏天不管天气如何热在室内总是挂着窗帘，在家里经常照镜子，反复表现出自认为最佳的表情和风度。父母没有办法，感觉女儿总得离家走上社会，所以求助于心理咨询。咨询过程：根据其父母的介绍和杨某的自我陈述，采取了分阶段的治疗。第一步：采用认知领悟疗法，通过对求助者的暗示和启发使其改变原有的错误的认知结构，逐渐能够正确客观地认识自己和其他事物，从而解除心理问题。第二步：采用家庭疗法，向杨某的父母说明情况，取得积极配合，共同治疗杨某的心理问题。第三步：采用伙伴疗法，使她在与伙伴的交往中逐渐培养起感情，让事实证明能够与伙伴友好相处，并从伙伴那里得到帮助、友谊和信任，消除害怕同学的心理。经过三个月的多次咨询治疗，杨某开始能和家人、同学正常交往。

求助者自知力（）。

A.无

B.完整

C.无法判断

D.部分存在

A

When I was young, I went looking for gold in California．I never found enough to make me rich．But I did discover a beautiful part of the country．It was called "the Stanislau"．The Stanislau was like Heaven on Earth．It had bright green hills and deep forests where soft winds touched the trees．

Other men, also looking for gold, had reached the Stanislau hills of California many years before I did．They had built a town in the valley with sidewalks and stores, banks and schools．They had also built pretty little houses for their families．

At first, they found a lot of gold in the Stanislau hills．But their good luck did not last．After a few years, the gold disappeared．By the time I reached the Stanislau, all the people were gone, too．

Grass now grew in the streets．And the little houses were covered by wild rose bushes．Only the sound of insects filled the air as I walked through the empty town that summer day so long ago．Then, 1 realized I was not alone after all．

A man was smiling at me as he stood in front of one of the little houses．This house was not covered by wild rose bushes．A nice little garden in front of the house was full of blue and yellow flowers．White curtains hung from the windows and floated in the soft summer wind．

Still smiling, the man opened the door of his house and signed to me．1 went inside and could not believe my eyes．I had been living for weeks in rough mining camps with other gold miners．We slept on the hard ground, ate canned beans from cold metal plates and spent our days in the difficult search for gold．

Here in this little house, my spirit seemed to come to life again．

I saw a bright rug on the shining wooden floor．Pictures hung all around the room．And on little tables there were seashells, books and china vases full of flowers．A woman had made this house into a home．

The pleasure I felt in my heart must have shown on my face．The man read my thoughts．"Yes," he smiled, "it is all her work．Everything in this room has felt the touch of her hand．"

One of the pictures on the wall was not hanging straight．He noticed it and went to fix it．He stepped back several times to make sure the picture was really straight．Then he gave it a gentle touch with his hand．
