Because he was tired, he left early. He left early because of tiredness. because of误接句子 Because of the train was delayed... Because the train was delayed... Because of the train delay... 位置错误 Of because the noise, I couldn't sleep. Because of the noise, I couldn't sleep. 五、记忆口诀 "because后接句，because of名代跟； 原因从句用前者，名词因素选后者； 转换先去主和be，保名保义最要紧！" 1．The soldier had to leave the army because of her _____.
