[請益] 句子結構分析

[prettyjoy (Business is business)]

煩請各位高手幫幫忙

1. This is ( more than either adults or children need) .

   This---代名詞,指青少年的睡眠量

   ( )是一個名詞子句嗎?

2. That is ( three hours less than <experts say they should get> ).

   That---還是個代名詞

   但 ( ) 跟 < > 如何解釋呢?


拜託大家了

感謝您 ~ ~

→ pptuser:看不懂要"解釋"什麼。much (比較級)，little(比較級)都是
→ pptuser:形容詞。three hours以文法上是副詞，修飾less。
