every evening after dinner,if not------from work,i will spend some time walking my dog

Question

答案是 tired 但是怎么解释的呐 不明白啊

Answer 1

if not tired from work 这是省略句。
原句应该是if i am not tired from work 如果我不是工作累的话
翻译：每天吃晚饭后，如果我不是工作累的话，我都会花一些时间去遛狗的。

Answer 2

every evening after dinner,if （I was）not--tired----from work,i will spend some time walking my dog

这是一个省略句，省略了I was ，be tired from,是某事儿疲劳~~~所以这里用tired

Answer 3

If not tired = if i am not tired from work

这是状语 从句的省略结构， 省略了主语和be

比如Be careful when (you are) crossing the street.

Answer 4

因为主句主语和从句主语一致，所以可以省略从句主语和BE动词，if not=if (I am)not 注意从句主语和BE动词必须同时省略，不能只省略其中一个

Answer 5

if not tired 是if I am not tired的简单形式，在意思上等同。
