句子改写，请帮忙

1.it will be necessary for you to see a doctor.（改为一般疑问句，要求使用must）。
1. Must it be necessary for you to see a doctor?
假如要求使用must了，那就掉到前边改为一般疑问句
Must是情态动词，后面加动词原形，所以用be动词的原形，necessary形容词做be的表语。

2.is it necessary for you to make so much noise?（用have to进行改写）
2. Do you have to make so much noise?
have to这个情态动词可以有时态和数的变化。

1. Is it a must for you to see a doctor?

2. Do you have to make so much noise?
第二句楼主做得对。

我认为:你改的都对!!

1.Will it be necessary for you to see a doctor?
2.Do you have to make so much noise?
Just my own opinion!

Is it necessary that you must see a doctor?

第二句楼主做得对。

1 Will must be it necessary for you to see a doctor?

2 You have to make so much noise?
