Nowadays, computer games are becoming more and more popular in many cities and towns.
   A lot of small shops along busy streets have been made into small game houses in order to get more money. These places are always crowded with people, especially young boys.
   In the computer game houses, people spend a lot of money competing（较量） with the machines. It's hard for one to win the computer, but one can make progress after trying again and again. People have a kind of gambling psychology（赌博心理）when they play computer games. The more they lose, the more they want to win. When class is over, the school boys run to the nearby computer game houses. Little by little（渐渐地）, they forget all about their lessons and fall far behind others. Some of them can get enough money from their parents. But some of them are not lucky enough to get the money. They begin to take away other students' money and become thieves.

材料一：魏晋以来，官员大多从各地高门权贵的子弟中选拔。权贵子弟无论优劣，都可以做官。隋炀帝时正式设置进士科，考核参选者对时事的看法，按考试成绩选拔人才。从此，门第不高的读本人，可以凭才学做官。唐朝时科举考试科目以进士、明经最重要，武则天时又推行了殿试和武举，唐玄宗时诗赋成为进士科主要考试内容。宋朝时考试内容重经义，大幅扩大进士录取名额。明清时科举考试只许在四书五经范围内命题，答卷的文体必须分为八个部分，被称为“八股文”。

材料二：由于文官制度自身发展的内在动力的驱使，以及中国科举考试的示范，西方国家在19世纪前后纷纷建立了文官考试制度。该考试制度吸取了科举制的合理内核，而舍弃了科举考试空疏无用的经典内容。

材料三：唐太宗在端门看见新科进士鱼贯而出，高兴地说：“天下英雄尽入吾彀中矣！”

——王定保《唐摭言》

“太宗皇帝真长策，赚得英雄尽白头。”
