英语语法问题有二

一、The reason why I plan to go is that she will be disappointed if I don't.里的that可以换为because吗？ 二、If you'd been minutes earlier,you would have seen the doctor. What's the meaning?It means that you were to be late?Thanks!

Answer 1

详细的解答一下

1 The reason why I plan to go is that she will be disappointed if I don't.里的that可以换为because吗？
不能 that she will be disappointed if I don't 从句是一个宾语从句
that引导宾语从句 无词义 口语或非正式文体中 可省略
because 不能引导宾语从句

另外
whether/if也可以引导宾语从句

再补充一点
why I plan to go 是个定语从句 why做引导词 并且在从句中做原因状语 reason只能用why引导

二、If you'd been minutes earlier,you would have seen the doctor. What's the meaning?It means that you were to be late?Thanks!

意思是 如果你早几分钟到，你就可以看到医生了
这句话是个虚拟语气
在这个条件状语从句中
指得是过去的发生的动作 即过去没有做成某事
所以用
If +主语+had done 从句用 主语+would have done

希望对你有所帮助~~O(∩_∩)O

Answer 2

1、不可以，因为前面有the reason了，that就是表示the reason引导的宾语从句
2、是的

Answer 3

不能。

Answer 4

一中不可以换为because，因为这里的 why 是关系代词，而because是连词，不能代换。
第二句 yes.
