咏雪
谢太傅寒雪日内集，与儿女讲论文义。俄而雪骤，公欣然曰：“白雪纷纷何所似？”兄子胡儿曰：“撒盐空中差可拟。”兄女曰：“未若柳絮因风起。”公大笑乐。即公大兄无奕女，左将军王凝之妻也。
陈太丘与友期
陈太丘与友期行，期日中，过中不至，太丘舍去,去后乃至。 元方时年七岁，门外戏。客问元方：“尊君在不？”答曰：“待君久不至，已去。”友人便怒：“非人哉！与人期行，相委而去。”元方曰：“君与家君期日中。日中不至，则是无信；对子骂父，则是无礼。” 友人惭，下车引之，元方入门不顾。

下列河流中，不是注入同一个大洋的是

      Computers can help many workers. They can also help thieves.
      There was one thief who worked in a bank of the United States. He paid for everything he needed by check (支票). Then he told the computer not to take any money from his account for the checks he wrote. The bank's computer did what he said. And it did not take any money from his bank account. One day the computer broke down. People had to do the computer's work. They soon found out what was happening.
      Another thief, who worked for a bank saw people filling in deposit forms (存款单). Many of these people did not know their account numbers, so they wrote only their names on the forms. They left empty places for their account numbers. The thief wrote his own account number in this place. When the computer read these forms it looked only at the account numbers. It did not look at the customers' names. It paid the money on these deposit forms into the thief's account .                           
       Then there was the bank worker who told the bank computer to take ten cents off every customer's account each month and put it into his own account. For a long time the bank's customers did not notice that they were losing ten cents every month. But then someone did notice and told the bank. That was the end of that little game!
