She said she ____________ here for another two weeks. A．stayed B．has stayed C．would stay D．had stayed 【答案】C 【解析】句意：女孩对无锡的美景感到惊讶。她说她将在这里再呆两个星期。此句考查宾语从句的时态，当主句是一般过去时的时候（客观真理除外），从句要用过去时态的某种形式，排除B；根据“for another two weeks.”再呆两个星期的时间，属于将来的时间，因为主句是一般过去时，从句要用过去将来时来表达，答案为C。 点睛：含有宾语从句的复合句，主、从句谓语动词的时态呼应包括以下三点内容： 1）如果主句的谓语动词是一般现在时，从句的谓语动词可根据需要，选用相应的任何时态。 2）如果主句的谓语动词是过去时，宾语从句的谓语动词只可根据需要，选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。 3）如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句用什么时态，从句时态都用一般现在时。 3．I don’t know if it _________ tomorrow.
