我不喜欢一个苦孩求学的故事。家庭十分困难,父亲逝去,弟妹嗷嗷待哺,可他大学毕业后,还要坚持读研究生,母亲只有去卖血……我以为那是一个自私的学子。求学的路很漫长,一生一世的事业,何必太在意几年蹉跎?况且这时间的分分秒秒都苦涩无比,需用母亲的鲜血灌溉!一个连母亲都无法挚爱的人,还能指望他会爱谁?把自己的利益放在至高无上位置的人,怎能成为为人类献身的大师?
我相信每一个赤诚忠厚的孩子,都曾在心底向父母许下“孝”的宏愿,相信来日方长,相信水到渠成,相信自己必有功成名就衣锦还乡的那一天,可以从容尽孝。可惜人们忘了,忘了时间的残酷,忘了人生的短暂,忘了世上有永远无法报答的恩情,忘了生命本身有不堪一击的脆弱。
父母走了,带着对我们深深的挂:念。父母走了,遗留给我们永无偿还的心情。你就永远无以言孝。有一些事情,当我们年轻的时候,无法懂得。当我们懂得的时候,已不再年轻。世上有些东西可以弥补,有些东西永无弥补。
“孝”是稍纵即逝的眷恋,“孝”是无法重现的幸福。“孝”是一失足成千古恨的往事,“孝”是生命与生命交接处的链条,一旦断裂,永无连接。赶快为你的父母尽一份孝心。也许是一处豪宅,也许是一片砖瓦。也许是大洋彼岸的一只鸿雁,也许是近在咫尺的一个口信。也许是一顶纯黑的博士帽,也许是作业簿上的一个红五分。也许是一桌山珍海味,也许是一只野果一朵小花。也许是花团锦簇的华衣,也许是一双洁净的旧鞋。也许是数以万计的金钱,也许只是含着体温的一枚硬币……在“孝”的天平上,它们等值。只是,天下的儿女们,一定要抓紧啊!趁你的父母还健在。

Television has also changed politics. The most distant areas can now follow state affairs, see and hear the politicians before an election. Better informed, people are more likely to vote, and so to make their opinion count.
Unfortunately, television's influence has been extremely harmful to the young. (76) Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents.
Also, the young are less patient. (77) Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen.
In the past, many young people ______.
A. knew the effects of war
B. went in for politics
C. liked to save the wounded in wars
D. were willing to be soldiers
