         _________ is called quantitative easing.
         (1) which (2) how (3) what (4) when

       (1) didn't need waking (2) needn't have woken

→ jayhsieh    :第三題，I [didn't]...表示已經發生完了，要用過去
→ jayhsieh    :完成式，had p.p.，但是needn't後動詞改原V變have
推 justin1943  :關代只能代上一個N
推 roisac      :leave sth.+adj.使某物處於某狀態，用法就是這樣子。
