Question

13．由于天氣惡劣，飛機起飛晚了兩個半個小時．
The planetook off two and a half hours late because of bad weather．

Answer 1

分析 took off two and a half hours late because of．

解答 答案：took off two and a half hours late because of．這里是說過去的事用一般過去時，起飛take off，take的過去式took，晚了兩個半個小時two and a half hours late，由于，結(jié)合后面的bad weather為名詞短語用because of，故答案是took off two and a half hours late because of．

點評 because是連詞，其后接原因狀語從句或回答以why開頭的問句； 
而because of是復合介詞，其后接名詞、代詞或動名詞，或者what引導的名詞性從句．
如 Because he is ill，he is absent today．
He is not at school because of his illness．
