1. 当宾语从句的内容是客观事实或科学真理时，不论主句是什么时态，从句都用一般现在时态。 2. 当主句谓语动词为think，suppose，guess, believe等, 并且主语为第一人称时，从句的否定词应转移为对主句谓语动词的否定, 即否定前移。 例如： The teacher said (that) the earth goes around the sun. I dont think I know you. I don t believe he will come. 3. “两副面孔” if 和 when 等既能引导宾语从句，又能引导状语从句。因此，碰到此种情况要认真分析。当从句表示将来时，若引导的是宾语从句，它们的时态常用一般将来时；若引导的是状语从句，它们的时态常用一般现在时代替将来时。 If it rains tomorrow, I won’t come.（条件状语从句） 　I don’t know if it will rain tomorrow. （宾语从句） 宾语从句用法 宾语从句需注意，几点事项应牢记。 一是关键引导词，不同句子词相异。 陈述句子用that；一般疑问是否（if, whether）替； 特殊问句更好办，引导还用疑问词。 二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。 三是语序要记清，从句永保陈述序。 Exercise Can?you?see________?
