对两个英语句子有点疑问

Question

1.Many children have missed out 4,500 hours of sleep by the time they are 7 years old.
这个是定语从句吗，若是，哪个是先行词?关系词呢？
2.Why are not most adults this way?这句话什么意思? this way在句中作什么成分

Answer 1

1不是定语从句，是时间状语从句
2这句话译为 为什么大多数人不这样？
这句话变为肯定句为：Most adults are not this way。可知，this way做表语。

Answer 2

Many children have missed out 4,500 hours of sleep by the time they are 7 years old. 就是大部分的小孩子到了7岁已经失去了4500小时的睡眠。

What are not most adults this way? 就在问为什么大部分的大人不是这样的？

Answer 3

1,不是定语从句，后面是状语从句

Answer 4

==未采纳==
