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(shuō)過(guò)去的事情用一般過(guò)去時(shí)，主語(yǔ)是we，不得不have to，后接動(dòng)詞原形，have的過(guò)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(dòng)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(píng) because是連詞，其后接原因狀語(yǔ)從句或回答以why開(kāi)頭的問(wèn)句；
而because of是復(fù)合介詞，其后接名詞、代詞或動(dòng)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．
