Developments in printing made it possible to produce books more quickly and cheaply. 印刷术的发展使更快更便宜地生产书本成为可能。 【点拨】此句中,主语为Developments in printing,谓语为made,it为形式宾语,possible为宾语补足语,真正的宾语为to produce books more quickly and cheaply。归纳来说,此句型结构为:主语+谓语+形式宾语it+形容词+动词不定式(真正的宾语)。如:,I found it exciting to go hiking on weekends. 我发现周末去徒步旅行是令人兴奋的。 Why do you think it very important to stop smoking? 为什么你觉得戒烟是非常重要的?,2. A much larger amount of information can be stored in more varied forms on the Internet than in books. 网络可以比书储存更大量、更多样化的信息。 【点拨】(1)a large amount of意为“大量的”,修饰不可数名词,相当于a good/great amount/deal of, much等。 (2)in the form of意为“以的形式”。,3. .but it was the invention of the World Wide Web that made it really useful to people. 但是,是万维网的发明使它变得对人们确实有用。 【点拨】这是一个强调句型,被强调的部分是the invention of the World Wide Web。强调句的基本结构为:It is/was+被强调部分+that/who+句子的其他成分,其中的it没有实际含义。被强调部分可以是主语、宾,语或状语。若被强调的是人,且为句子主语时,用who或that皆可;若被强调的是其他成分,则一律用that引导。强调句型的判断方法是将It is/ was. that/ who去掉,若剩下的主干完整,即为强调句型。如: It was on a cold morning that I was born. 我是在一个寒冷的早上出生的。 It is his mother that/who prepares the meals. 是他母亲做的饭。,4. .so not all people can afford them. 所以,并不是所有的人都能买得起它们。 【点拨】在英语中,all, both, every, everyone, everything, everybody, everywhere等和否定词not或no连用时,表示部分否定,而非全部否定。若表示全部否定,要用none, neither, no one, nothing等。如: Not every person likes living in the cities. 并不是每一个人都喜欢住在城市。,
