Hoping to be stronger to compete with the world's best,Murray has put on about 4 kg by eating

问题描述:

Hoping to be stronger to compete with the world's best,Murray has put on about 4 kg by eating
twice as much as his usual.请问hoiping to be 这句,为什么hoping 加ing ,是语法还是,什么句型呢,还有最后的usual前面为什么加his,usual又不是名词,his可以修饰副词吗

这句话的主语是Murray,因此前面这句Hoping to be stronger to compete with the world's best在成分上只是一个从句,起修饰作用,当然动词要变ing形式,因为Murray has put on about 4 kg by eating句中has put on 是主...
