第二类：动词修饰语
Unlike a noun modifier, a verb modi fier does not have to touch the subject.
Some verb modifiers may apply to both the verb and the verbs subject. In these cases,
you must make sure that the subject makes sense with the modifier. （逻辑主语）
注意动词修饰语的位置
Wrong: The nameless symphony was at last performed, decades after it was composed,
yesterday. （yesterday修饰composed，与前半句语义矛盾）
Right: The nameless symphony was at last performed yesterday, decades after it was
composed.
