Question

1. My sister is going to buy a comic book tomorrow.(变为由what引导的特殊疑问句）

还有一个问题：
2. First,put a beach seed in the soil.(对该句提问）

Answer 1

1.What is your sister going to do tomorrow? 由What 引导，此处就是“干什么”，所以是对 buy a comic book提问。

2.用What 就是：What do you do first? 对,put a beach seed in the soil. 提问，第一步干嘛？
What do you put in the soil first? 对a beach seed提问，你第一步在土壤你放啥？
用Where 提问就是 Where do you put a beach seed？对in the soil提问，你把种子种在哪儿？
此外：加YOU是因为第二句是对祈使句提问，祈使句的主语在这里应该是you ，I，或者we等等，默认为You.
希望对你有用，望采纳
