I'll be the first to admit that I am a technophobe (对技术有恐惧感的人). Who would

have guessed that a website would help repay a 20-year-old loan?

I'll always remember my last day at school. My best friend, Jenny, had organized a

party in the Sixth Form Common Room. Jenny asked me to go to the supermarket with her to

buy all the snacks. "I'm really looking forward to this party, Stingy (小气)," she said.

Everyone called me Stingy instead of Debbie because they thought I didn't like to spend

money. Actually, it was true.

"There's lots of money in the kitty. Let's go crazy!" Going crazy meant buying enough

snacks to feed an army. It came to￡19.90, which was a lot of money in 1982. Jenny gave

me a guilty look. "I've left the kitty money in the common room. Can you pay and I'll give

you back the money?"

"Sure," I replied, trying to look relaxed." Neither a lender nor a borrower be" was

my motto but I didn't want to look stingy. I gave ￡20 to the impatient shop assistant.

Well, the party was a great success-so great that I completely forgot about my loan

until I was flying to America the next day. I was going to live with my uncle's family

until I started university.

I tried to get in touch with Jenny but her family had moved. My ￡20 was lost. Until…

I'd heard about a website called Friends Reunited which helped people contact old

school friends. My husband helped me log on and find my school. There she was, Jenny

Frost.

"I'm now married, with a beautiful daughter called Debbie. Does anyone know how to

get in touch with Debbie 'Stingy' Jones? I still owe her ￡20!"

We met two months later and the ￡20 was returned, plus interest of course. After

all, I'm a bank manager now, so loans are my business.

1. Why did Jenny spend a lot of money on the snacks? [ ]

一般资料：男，20岁，工人。
求助者主诉：因害怕触电，焦虑不安，失眠2个多月而来就诊。
案例介绍：求助者自幼胆小内向，常受同龄儿童欺负。高中毕业因成绩不好未考上大学，来某工厂当电工。求助者上班后对电十分恐惧，看到“高压危险!”“小心触电!”的警句和警示标志就十分紧张。上班一周后的一天，在工作台面操纵开关时，手指不小心接触了工作台面，顿感手臂发麻，全身发软，随即倒地。同事赶紧围上来，见其呼吸急促，面色苍白，语声轻微，是“触电”了。经测试，工作台面并无电流。求助者无法正常上班，求助者的父亲强迫其上班，并骂他是草包。于是求助者焦虑不安，夜不能寐。因求助者认为工作台面有电不敢进工作间，由班长陪同就医。经协商制定如下治疗方案：
第一步，给求助者讲解一些电的基本知识、工作台的结构原理，使求助者从观念上改变工作台面漏电的看法。
第二步，由班长或老师傅带领求助者和另外一位学徒上班。班长首先演示，那位与求助者同时进电站的学徒工接着学做，然后让求助者学做。既操作全部的旋钮开关，又用手抚摸工作台面及工作台体的其他部分。最后接触工作房内的其他设施，如墙壁、滑动椅等。每当求助者模仿一个动作后即给予口头赞赏，并让其观察动作的结果——各仪表的变化或其他什么指标，使求助者确认工作台处于工作状态，但确实没有漏电。
经上述治疗后不到半个月，求助者已能单独上班。

影响该疗法的效果的因素包括( )。

A．求助者的年龄

B．示范者的感染力

C．示范者与求助者的相似性

D．对正确模仿行为强化的时机
