He says (that) he has studied English for five years. he was studying English from 8 to 9 yesterday evening. he studied English five days ago. * 随堂演练 课后作业 考点汇聚 基础自查 2) 当主句的谓语动词为过去时态 (并非只指一般过去时，只要是过去的时态形式即可) 时，从句的谓语动词必须用它所相对应的过去时形式。如果从句的动作发生在主句之前，则从句要用过去完成时态。 he studied English every day. he was studying English now. he would study English tomorrow. He said (that) he had studied English for five years. he was studying English from 8 to 9 yesterday evening. he studied English five days ago. 注意：“could” 用于表委婉语气时，不是指过去时, 所以从句用 “can” 而不能用“could”。 Could you tell me when I can leave? * 随堂演练 课后作业 考点汇聚 基础自查 3) 当从句描述的是事实、真理或格言、谚语时，从句谓语动词的时态不受主句时态的限制，都用一般现在时。 He says（said）that the earth goes around the sun. He says（said）that it is better to give than to receive. * 随堂演练 课后作业 考点汇聚 基础自查 三．否定转移的条件： 1）主语必须是第一人称（I、we） 2）谓语动词必须是think、believe、suppose等 当动词think, believe, imagine, suppose, consider, expect, fancy, guess后接一个表示否定意义的宾语从句，且主句的主语是第一人称时，其否定通常转移到主句上，其反义疑问句一般与宾语从句一致。 I don’t believe it is right for him to treat you like that. I don’t think we need waste much time on it. I don’t believe that man is killed by Jim, is he? We suppose you have finished the project, haven't you? * 随堂演练 课后作业 考点汇聚 基础自查 四．必须使用whether的两种情况： 注意：宾语从句中只能用whether不能用if的情况： ①在介词后面的宾语从句中不用if引导 Everything depends on whether we have enough money. ②宾语从句中有or not时不用if引导. I don’t know whether the movie star will come or not. ③和不定式连用作宾语时不用if引导. Whether to go the
