长句分析
Therefore,when we consider the amount of pollution produced per passenger kilometre travelled,a car journey is no more fuel efficient and environmentally friendly than a long-distance flight.中1.produced per passenger kilometre travelled是什么句式结构?特别是后面一个travelled如何解释语法现象?2.什么词性,可以修饰什么类型的词?3.no more than fuel efficient 是否搭配是否合理,4.fuel efficient and environmentally friendly 这些词可否插入no more than之中 ,是否修饰more?more在这里是什么词性?并起什么作用?
长句分析Therefore,when we consider the amount of pollution produ
1.(pollution)produced per passenger kilometre travelled 每人每千米所产生的污染量
2.per 是“每个,一个”的意思,travelled 修饰kilometre,意即“被走过的千米数”
3.no more ...than ---不比...更...a car journey is no more fuel efficient and environmentally friendly than a long-distance flight 意思即“一个长途飞行比一个汽车旅程更节能且环保”fuel efficient (或fuel-efficient )是一个形容词词组,即“节省燃料的”
4.fuel efficient and environmentally friendly 用在no more 后面,因为no more 后面必须加形容词或副词,表程度,more用来修饰改成份,而than后面必须加被比较的对象
