【02】周雯的妈妈是豫林水泥厂的化验员。一天,周雯来到化验室做作业。做完后想出去玩。等等,妈妈还要考你一个题目,她接着说,你看这6只做化验用的玻璃杯,前面3只盛满了水,后面3只是空的。你能只动1只玻璃杯,就便盛满水的杯子和空杯子间隔起来吗?爱动脑筋的周雯,是学校里有名的小机灵,她只想了一会儿就做到了。请你想想看,小机灵是怎样做的?

【03】一间囚房里关押着两个犯人。每天监狱都会为这间囚房提供一罐汤,让这两个犯人自己来分。起初,这两个人经常会发生争执,因为他们总是有人认为对方的'汤比自己的多。后来他们找到了一个两全其美的办法:一个人分汤,让另一个人先选。于是争端就这么解决了。可是,现在这间囚房里又加进来一个新犯人,现在是三个人来分汤。必须寻找一个新的方法来维持他们之间的和平。该怎么办呢?按:心理问题,不是逻辑问题

二、阅读理解题

For several years, Americans have enjoyed teleshopping watching TV and buying things by phone. Now teleshopping is starting in Europe. In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.

Teleshopping is becoming popular in Sweden, for example. The biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made $100 million. In France there are two teleshopping channels, and the French spend about $20 million a year to buy things through those channels.

In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then the government allowed more telepshopping. Other channels can open for telebusiness, including the largest American teleshopping company and a 24-hour teleshopping company. German businesses are hoping this new teleshopping will help them sell more things.

Some people like teleshopping because it allows them to do their shopping without leaving thei***omes. With all the problems of traffic in the cities, this is an important reason. But at the same time, other Europeans do not like this new way of shopping. They call teleshopping junk(垃圾)on the air. Many Europeans usually worry about the quality of the things for sale on TV. Good quality is important to them, and they believe they cannot be sure about the quailty of the things on TV.

The need fo***igh quality means that European teleshopping companies will have to be different from the American companies. They will have to be more careful about the quality of the things they sell. They will also have to work harder to sell things that the buyers cannot touch or see in person.
