瓦特与蒸汽机
机器数量不断增多，为了带动机器，人们常常把工厂建在靠近河流的地方，利用水力带动机器。但是，很多地方受自然条件的制约不能使用机器。于是，人们开始寻找更加方便、更加有效的动力。英国机械师瓦特借鉴前人的研究成果，经过多年钻研，改进了蒸汽机。1785年以后，瓦特改进的蒸汽机首先在纺织部门投入使用，受到广泛欢迎。
瓦特的蒸汽机出现以后，在许多的生产部门，人们利用蒸汽机提供的动力带动机器，进行生产，极大地促进了大工厂生产的发展。从此，人类进入了“蒸汽时代”。

语言素材：
Business Motorola set out a special training plan programme for children last week with the aim of developing children's business skills and preparing them for a future as entrepreneurs.
Eighty-seven children aged between 12 and 16 from Beijing and Tianjin attended the one-week training programme called Youth Discovery directed by Motorola University's(MU) instructors and marketing specialists. The children learned about dealing with a practical problem-marketing and worked out a marketing plan by themselves. Last week 26 children of Motorola employees in Tianjin completed their training in the MU-Tianjin Learning Center.
Through the training programme, children learnt how to get information through different kinds of sources, determine end-user needs, make up messages of value to customers, and communicate using various means and equipment.
Educators acted only as team directors, providing children to discover their own answers. The children gave their solutions to Motorola's management and their parents on the last day of the programme.
The children, most of whom were primary and middle school students, presented themselves freely. The students said that they preferred the open and practical way of learning.
Youth Discovery, started by Motorola's former president Robert Galvin, designed and carried out by Motorola University, aimed to bring the talents of young people into full play and encouraged them to discover how their skills can contribute to a team to help it reach an aim.
