英語語法：分不清分詞狀語
我今天問了一個這樣的問題
Asia,and North America.The Antarctic is a continent almost as large as Europe and Australia combined,centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world -- the Atlantic,Pacific,and Indian Oceans.
我問的是centered on 在這個句子里面是不是作動詞,因為我感覺centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world -- the Atlantic,Pacific,and Indian Oceans.前面省略了主語The Antarctic 也就是is 和centered on 是并且謂語,但是今天又一個高手告訴我說這個是做非謂語.我有時候真分不清啊,我看見動詞總是相當(dāng)然認(rèn)為動詞前面缺少主語,然后就把動詞當(dāng)成謂語了.
