「（疑問詞）〜か」用来表示疑问或者询问，相当于中文的「是否」或者「是不是」。
当你想要确认某件事情是否属实或者是否发生时，可以使用这个语法。
比如，你想问别人是否要去看电影，就可以说: 你要去看电影吗？再比如，你想知道某个人是不是喜欢吃寿司，就可以问: 他喜欢吃寿司吗？总之，这个语法用来提出疑问，确认事实或者情况。

The grammar pattern "(question word) + か" is used to form a question in Japanese.
The question word can be something like "who," "what," "where," "when," "why," "how," etc.
By adding "か" at the end of the question word, you are essentially turning a statement into a question.
For example, if you have the statement "彼は学生です" (Kare wa gakusei desu) meaning "He is a student," you can turn it into a question by adding "か" at the end of "学生" to get "彼は学生ですか" (Kare wa gakusei desu ka) meaning "Is he a student?"
