напиши как будет по английски, очень нужен точный перевод. см внутри...

He understands me
Does he understand me?
He does not understand me (does not = doesn't)
Does he not understand me? (обратите внимание, Doesn't he understand me? = Не понимает ли он меня? )

She loves you
Does she love you?
She does not love you (does not = doesn't)
Does she not love you? (обратите внимание, Doesn't she love you? = Не любит ли она тебя?)

Типа того:

He understands me
Does he understand me?
He doesn't understand me
He doesn't understand me? - это не совсем вопрос, просто переспрашиваем, подразумевая [Do you mean] he doesn't understand me? (а вот вопросы: He doesn't understand me, does he? = Он ведь не понимает меня? ; Doesn't he understand me? - Неужели он не понимает меня? )

И аналогично:
She loves you
Does she love you?
She doesn't love you
She doesn't love you? (She doesn't love you, does she?; Doesn't she love you?)

В последнем случае важно понять, какого рода вопрос вы хотите задать.

He understands me
Does he understand me?
He does not understand me
Does not he understand me?

She loves you
Does she love you?
She does not love you
Does not she love you?
