Question

ifhis brother won't come to help you,he will不加宾语？

if his brother won't come to help you,he will.是什么用法

Answer 1

If his brother won't come to help you,he will. 这个句子使用了省略。

he will的完整表述其实是he will come to help you，这里是为了避免与if his brother won't come to help you重复。

汉语习惯重复，英语习惯省略，这是一种常见的文化现象。英语中还存在很多其他的省略现象。比如并列句的省略现象：His name is Peter and mine Henry. （省略谓语动词is）。再比如复合句的省略现象：When asked, he couldn't figure out the right answer. (从句省略了he was)。

Answer 2

if his brother won’t come , he will

if 条件句 ( 一般现在时）+ 主句 will do ,

题目句子的时态和书写有错误，须修改。

If his brother doesn’t come , he will

come .

句子汉语：如果他的弟弟不来，他会来。

Answer 3

如果他的哥哥不来帮你，他会来。
语法点：主句省略（come to help you）

Answer 4

if引导的是状语从句，如果他哥哥不来帮你，他就会来。
