我想問係present tense入面，係幾時用"is"同"does"嫁？

Does 係 present tense 入面有兩種用法：

1. 用作帶有動詞既疑問句。

例子：Dose she like to eat apple?

2. 用作帶有動詞既否定句。

例子：She does not like to eat apple.

Is 係 present tense 入面都有兩種用法：

1. 用作狀況既疑問句。

例子：Is she beautiful?

2. 用作陳述既句子或回答狀況疑問句。

例子：She is beautiful.
希望可以幫到你

is用係句子,
does用係問題.
eg:
She is eating an apple.
Does she like to eat apple?
