Question

she goes to school by bus改为否定句

Answer 1

She goes to school by bus改为否定句是She doesn't go to school by bus.

当主语是第三人称单数时,在谓语动词前加does not = doesn’t, 谓语动词打回原型 。

例如：He knows my name.  变为否定句时，在谓语动词knows前面加 doesn't, 谓语动词knows打回原形know. 其否定句如下：

He doesn’t know my name. 

Answer 2

行为动词做谓语变否定句，一般现在时态主语是第3人称单数，借助助动词doesn't，原来的动词要还原。

She doesn't go to school by bus.

Answer 3

回答和翻译如下:
She does not go to school by bus.
她去学校不坐公车。(英语句子翻译，改为否定句)

Answer 4

变为否定句是：She doesn't go to school by bus. 一般现在时实义动词肯定句，变为否定句需要借助助动词，don't或doesn't，句子中主语是第三人称单数形式，所以需要借助doesn't，放在实义动词前面，并且把动词恢复原形。

Answer 5

否定句是She doesn't go to school by bus.
