高中英语句子
At that time i had no idea how i could hand it to him without being seen.为什么这句话中idea后面不要that?
It is well konw what a person eats causes changes in the body.这句话中为什么know后面不要that?

第一个句子idea后引导的是个同位语从句,对前面的idea这个抽象名词进行解释说明.疑问副词how在从句中作方式状语,意为“怎么样”.而that引导同位语从句时在句中不作任何成分,而且没有意义,它一般引导的是一个意义完整的句子,一个事实.
第二个句子中what a person eats causes changes in the body是主语从句,it是形式主语.what是疑问代词,在从句中作eat的宾语,意为“所...的”.而that引导主语从句时在句中不作任何成分,没有意义.这里如换成that,从句就缺少成分,意义也不完整.但可以说It's well known that what a person eats causes changes in the body.
总结：这两个句子都是名词性从句.疑问代词和疑问副词在从句中充当成分,有意义.但that引导名词性从句时,在句中不充当成分,没有意义.致学
