She does not believe she can do betterin the future.

Answer 3

She believes she can do better in the future.句子本来应该是She believes （that） she can do better in the future, That可以省略,因此整个句子的谓语动词是believe,是实义动词。在改为否定句时应借助助动词，主语是she-第三人称单数，则借助does。

因此句子改为否定句为
She does not believe she can do better in the future。
