1．My teenage son Karl became withdrawn after his father died．As a single parent，I tried to do my best to talk to him．But the more I tried，the more he pulled away．When his report card arrived during his junior year，it said that he had been absent 95times from classes and had six falling grades for the year．In this case he would never graduate．I sent him to the school adviser，and I even begged（乞求）him．Nothing worked．
One night I felt so powerless that l got down on my knees and begged for help．"Please God，I can't do anything more for my son．I'm at the end of my rope．I'm giving the whole thing up to you．"
I was at work when I got a phone call．A man introduced himself as the headmaster．"I want to talk to you about Karl's absences．"Before he could say another word，I choked（哽咽） up and all my disappointment（失望） and sadness over Karl came pouring out into the ears of this stranger．"I love my son but I just don't know what to do．I've tried everything to get Karl to go back to school and nothing has worked．It's out of my hands．"For a moment there was silence on the other end of the line．The headmaster seriously said，"Thank you for your time．"and hung up．
Karl's next report card showed a marked improvement in his grades．Finally，he was even on the list of the best students at school．In his fourth year，I attended a parent-teacher meeting with Karl．I noticed that his teachers were surprised at the way he had turned himself around．
After the meeting，Karl said，"Mum，remember that call from the headmaster last year？"I nodded．
"That was me．I thought I'd play a joke but when I heard what you said，it really hit me how much I was hurting you．That's when I knew I had to make you proud．"

解答 36-40CADBD
36．C 从As a single parent，I tried to do my best to talk to him，but the more I tried，the more he pulled away作为一名单身母亲，我尽自己最大努力与儿子谈心，但是我尝试越多，他越是不跟我说．所以Karl became withdrawn，相当于refused to talk to others．可知选择C．而withdrawn本意是孤僻的，沉默寡言的．
37．A 推理题．从后文儿子的告白it really hit me how much I was hurting you，自己意识到自己的行为对母亲的伤害有多深，所以他是羞愧地说不出话来从而沉默了，故选A．
38．D 从上文Nothing worked（不起任何作用）．One night I felt so powerless that l got down on my knees and begged for help．"Please God，I can't do anything more for my son．我感觉很无力，以致跪下来祈求帮助，说：我无法为我儿子多做任何事情． 所以推测作者是走投无路，山穷水尽了，故选择D．
39．B 推断题．整篇文章都是在表明一个伟大的单亲母亲在为儿子默默地付出，用自己的真心感动儿子，使儿子振作起来．所以答案B正确，母亲的爱在青少年的生活中起着重要作用．Mother's love plays an important part in teenagers'life．故选B．
40．D 从下文After the meeting，Karl said，"Mum，remember that call from the headmaster last year？"I nodded．"That was me．I thought I'd play a joke but when I heard what you said，it really hit me how much I was hurting you．That's when I knew I had to make you proud．"推测：终于一次儿子想借校长的名义跟妈妈打电话开个玩笑时听到了母亲的心声，从此振作起来，逐渐成了母亲的骄傲…因此D项答案A joking phone call符合题目要求．
