→ zebracoco: 不是summer 而是number 10/17 23:22
→ kaifrankwind: 時態是一樣啊 都是完成式(直到2006這時間點) 10/17 23:52
→ dashihito: 如果時間點一樣為何是"which 'is' estimated"？所以相 10/19 01:24
→ dashihito: 較於現在，add的動作更先發生，因此用"to have added" 10/19 01:25
有段句子想請教
By 2006 , this summer had increased to 113,000 , which is estimated to
have added US 1.3 billion to Australia's economy in that year .
請問為何estimated to +have + pp ?
我的理由是上下句是同一時間(指2006年),所以時式應該一樣
所以應該是estimated to add....而不是estimated to have added...
請問各位有何見解能替小弟解惑
謝謝
