The normal price of a ticket is £2,000. 1normal,正常的。 2price,价格。注意英语里的price不说贵或便宜的,而是说高低的,即不能说诸如an expensive price,而要说a high price。 读写重点 英语句子写作中,要尽量避开头重脚轻的问题,即主语部分比谓语部分的内容更长。而假如要避开头重脚轻的常见方法就是采纳形式主语it,然后把句子的逻辑主语放到句子后面。比如,本课里出现的句子“It suddenly occurred to one of the workers to open up the box.”,这句话中的it就是形式主语,用来代替逻辑主语
