雅思阅读的命题依据及规律

　　照应关系

　　照应指用代词等语法手段表示的语义关系。英语中的照应分为3类：人称照应、指示照应和比较照应。其中较难的是分句照应。分句照应指的是某些词语的所指对象不是词或者短语，而是分句、句子、句子组合，甚至一个完整的语篇。可以用做分句照应的词语分为以下3类。

　　here，it，this等词汇既可用于前照应，又可用于后照应。

　　that，above，theforegoing等只用于前照应。

　　as follows，thefollowing，below，thus等仅用于后照应。

　　这一语言现象常常是命题点。

　　Example:

　　It looks as if itcame straight from the set of Star Wars. It has four-wheel drive and rises aboverocky surfaces. It lowers and raises its nose when going up and down hills. Andwhen it comes to a river, it turns amphibious: two hydrojets power it along byblasting water under its body. There is room for two passengers and a driver,who sit inside a glass bubble operating electronic, aircraft-type controls. Avehicle so daring on land and water needs windscreen wipersbut it doesnt haveany. Water molecules are disintegrated on the screens surface by ultrasonicsensors.
