编辑你好! 漫步都市街头,我发现越来越多新的轿车,在其尾部行李箱盖外端都装有一块像是倒装的飞机机翼,使原本就拥有华丽迷人外观的轿车又平添许多妩媚和神气。我想这新颖美丽的汽车尾翼应该不仅是厂家为了好看才给轿车安装的装饰件,那么它的主要作用是什么呢? Edit Hello! Walking the streets of the city, I found that more and more new sedans, fitted with a flutter-like aircraft wing at the outer end of the trunk lid, have added to the sedan that otherwise would have a magnificent look Many charming and airy. I think this new and beautiful car tail should not only be decorated to look good to the car manufacturers to install decorative parts, then its main role is what?
