Question

8．由于下大雨，我們不得不待在旅館．
We had to stay in the hotel because of the heavy rain．

Answer 1

分析 We had to stay in the hotel because of the heavy rain．

解答 答案：We had to stay in the hotel because of the heavy rain．這里是說過去的事情用一般過去時，主語是we，不得不have to，后接動詞原形，have的過去式是had，待在旅館stay in the hotel，故We had to stay in the hotel，由于這里用because of后加名詞代詞或動名詞，大雨the heavy rain，故答案是We had to stay in the hotel because of the heavy rain．

點(diǎn)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(fù)合介詞，其后接名詞、代詞或動名詞，或者what引導(dǎo)的名詞性從句．
如 Because he is ill，he is absent today．
He is not at school because of his illness．
