高中英语同位语从句语法
同位语从句和主语从句、宾语从句、表语从句共同称为名词性从句.
同位语从句在句中起同位语的作用.它一般跟在某些抽象名词（如fact,news,idea,promise等）的后面,用以说明或解释前面的名词.
1.引导同位语从句的连词多用that.that在同位语从句中只起连接作用,不充当任何成分,但不可省略.如：
① The fact that the earth is becoming warmer and warmer is clear.
② The news that our team won the football game inspired all the fans.
③ They introduced the idea that children could learn to read as babies.
④ Tom made his teacher a promise that he would never be late again.
2.少数情况下同位语从句也可用连词whether和连接代词who,what,which或连接副词when,where,why,how等引导.
① I have no idea whether it is safe to sail in this weather.
