2、确定她什么时候会来。(二)宾语从句 宾语从句指主从复合句中用作宾语的句子。宾语从句通常由从属连词、连接代词或连接副词引导。宾语从句的语序要用陈述语序，不能用疑问语序。1.引导词的使用(1)that引导的宾语从句that只起引导词作用，不充当句子成分，没有词义，且通常可以省略。He thinks (that) he will be famous some day.他认为他总有一天会出名的。主句中的谓语动词是believe，expect，explain，suggest，imagine，prefer，promise，report，understand，warn，say，think，tell，know

5、一般现在时。The teacher told the students that the Earth goes around the Sun.老师告诉学生们地球围绕着太阳转。3.从句的语序 无论主句是陈述句还是疑问句，宾语从句的语序都要用陈述语序，即：连接词+主语+谓语+其他。 Can you tell me who(m) we have to see?你能告诉我我们必须见谁吗?4.否定的转移 当主句的谓语动词是think，believe，suppose等，主句的主语是第一人称，且时态为一般现在时时，后接从句的否定词通常要前移，即否定主句动词。I dont think he is right.
