這里要注意下add to sth這個片語的意思,"to increase sth in size, number, amout etc.".它不僅可以指數量的增加,還可以指規模的擴大,而這里的規模,所指也很廣泛,可以指實際意義上的規模,比如下面一個例子:
The house has been added to (= new rooms, etc. have been built on to it) from time to time.
這房子一次又一次地在擴建.
但也可以指抽象的"規模",比如困難(difficulty),困惑(confusion)等,就是說,使原本困難的事變得更加困難,原來就不清不楚的事情變的更加迷糊.
The bad weather only added to our difficulties.
惡劣的天氣只是增加了我們的困難.
