[ 语文 ] 潇洒钱钟书仲利民学识渊博、才华出众的钱钟书,偏偏不喜抛头露面,拒绝记者的采访,躲避摄影记者

潇洒钱钟书
仲利民
学识渊博、才华出众的钱钟书,偏偏不喜抛头露面,拒绝记者的采访,躲避摄影记者的镜头。最有趣的一次,钱钟书与夏衍同住一病房,夏老过生日,他的孙女将蛋糕也送了一大块给钱钟书,这时的摄影记者从后面开始偷偷地拍摄,当记者大着胆子转到前面来的时候,钱钟书先生居然拉起了被子连人带蛋糕一起盖起来。
香港记者林湄到北京想采访钱钟书,又怕遭到钱先生拒绝,就邀请当时的《文艺报》副主编吴泰昌先生帮忙,吴先打了个电话被其婉拒,就让林来一次突然袭击。当他们出其不意地来到钱钟书房门口时,钱先生幽默地说:“泰昌,你没有引蛇出洞,又来瓮中捉鳖了……”让人感受到钱钟书并非不近人情,他拒绝媒体的采访,仅是自己坚持的一种生活方式。
吴泰昌在《人民文学》杂志做编辑时,想约钱钟书先生写点文章,想不到钱钟书先生突然起身摆着手大声说:“写文章的事今天不谈。”不过,事隔一年多,当吴身体有恙,钱钟书先生却特意去信,“去秋承惠过快晤,后来,听说您身体不好,极念。我年老多病,渐渐体贴到生病的味道,不像年轻时缺乏切身境界,对朋友健康不甚关心。奉劝您注意劳逸结合,虽然是句空话,心情是郑重的。杨绛同候。”这句“空话”里又包含钱钟书先生对友人多少关心的真情实感啊!
钱钟书先生淡泊名利、自甘寂寞,可是媒体却总是想请出这位不愿露面的人物,他们知道杨绛先生好说话,就想从杨绛先生这里打开缺口,在电话里对杨绛先生说:“被录制的文化名人,还可以得到一笔可观的报酬——钱。”想不到钱先生幽默地从旁边插话道,“我都姓了一辈子钱,难道还迷信钱吗?”
钱先生和太太的感情十分融洽,经常给人“胶着”的亲密感。他们一同上班,一同下班,总是肩并肩,手携手。即使在钱钟书先生被打成“反动学术权威”之后,夫妻感情依然如故。情绪从未低沉、沮丧过。文革中,造反派动手打他,他就还击。有一次与造反派大打出手后,扬名千里,连“造反派”都敬重他“三分”。可见钱先生柔中有刚,做人界线分明,拿得起,放得下。
最有趣的要算钱钟书先生进入清华大学时的数学成绩了。一直有传闻说他当时的数学成绩是0分,当时的校长罗家伦破格录取。不过,我最近查阅了资料,发现钱钟书先生对此事有自己的说法:数学成绩并非0分,而是稍高的15分。就这样,也未及格,但是不妨碍钱钟书先生成为一代学术名人,反而增添了些名人轶事的趣味。
杨绛先生在《干校六记》里有一段有趣的记述,有一次她指着菜园里玉米秸搭盖的窝棚问钱钟书:“给咱们这样一个窝棚住行吗?”钱认真地想了一下,说:“没有书。”读到这句话,我忽然明白钱钟书先生为什么逃避记者的缘由了,钱先生一辈子并不在乎名利,他连窝棚住着都不在乎,只要有书就成了。没有书,不让他研究学问才是最大的痛苦,生活上及别的方面都可以忍受。
小题1:下列对文章有关内容的分析和概括,最恰当的两项是( )( )(4分)
A.香港记者林湄到北京想采访钱钟书,又怕遭到钱先生的拒绝,一个“怕”字形象地表现了钱钟书对别人无情的态度。
B.当时的校长罗家伦录取钱钟书,作者推测他的数学成绩不是0分,而是 15分,但是这不妨碍钱钟书先生成为一代学术名人。
C.钱钟书先生和太太一同上班,一同下班,总是肩并肩,手拉手,经常给人“胶着”的亲密感,表现了钱先生珍视感情的一面。
D.文中写“连‘造反派’都‘敬重’他三分”,是从侧面突出了钱先生柔中有刚,做人是非分明,拿得起放得下的性格。
E.文章首尾都写到有关钱钟书先生的趣事,通过这些趣事写出了钱钟书一辈子不在乎名利,生活及其他方面都可以忍受。
小题2:在这篇纪念钱钟书先生的文章中,却用大量篇幅写了吴泰昌,请说说这样写的原因是什么?(5分)
答:
小题3:请阅读全文,概括出钱钟书先生的“潇洒”体现在哪些方面?(5分)

[ 英语 ] 阅读理解。         This story is about a beautiful

阅读理解。
        This story is about a beautiful, expensively dressed lady who complained to her psychiatrist (精神科医生) that she felt her whole life was empty; it had no meaning. So the psychiatrist called an old lady who cleaned the office
floors, and then said to the rich lady, "I'm going to ask Mary here to tell you
how she found happiness. All I want you to do is listening."
        So the old lady put down her broom and sat on a chair and told her story, "Well, my husband died of malaria (疟疾) and three months later my only son was killed by a car. I had nobody. I had nothing left. I couldn't sleep; I couldn't eat; I never smiled at anyone. I even thought of taking my own life. Then
one evening a little kitten followed me home from work. Somehow I felt
sorry for that kitten. It was cold outside, so I decided to let the kitten in. I got it some milk, and it licked (舔) the plate clean. Then it purred (发出呼噜声) and rubbed against my leg, and for the first time in months, I smiled. Then I
stopped to think: if helping a little kitten could make me smile, maybe doing
something for people could make me happy. So the next day I baked some
biscuits and took them to a neighbor who was sick in bed. Every day I tried to do something nice for someone. It made me so happy to see them happy.
Today, I don't know of anybody who sleeps and eats better than I do. I've
found happiness by giving it to others."
        When she heard that, the rich lady cried. She had everything that money
could buy, but she had lost the things which money cannot buy.
