1. Do you know what?

2. What do you know?

(What is the difference between them?)

3. Which club do you go to?
3-1. I go to a dram club.
3-2. I go to the drama club.
(Which answer is right? Are both correct?)

4. I am Bora, your student from last year.(Is it correct? Do we have to use 'from' in this sentence? Do you have some other expressions having the same meaning? Does this sentence mean that Bora is still somebody's student?)

1 and 2 are almost the same on the surface.

1 is asking someone if they know something in specific, and you might be expecting a particular answer.

2 is more of a general question, almost like asking "how are you?"

~~~~~~~~~~~~~~~~~~~~~~~~

3-1 is saying you go to one of several drama clubs. (Watch the spelling of "drama.")

3-1 is saying you go to the only drama club that exists.

~~~~~~~~~~~~~~~~~~~~~~~~

In 4, "from" is correct. It simply means that Bora was in the teacher's class last year, but doesn't indicate whether Bora is still in school or has already graduated.

You could also say these: "I am Bora. I was in one of your classes last year." or "I am Bora. I was in your class last year."

1. "Do you know what?" is a question asking if the speaker has knowledge or understanding about something specific, without stating what that something is. It is an open-ended question, leaving the topic unspecified.

2. "What do you know?" is a question asking about the speaker's overall knowledge or understanding. It is also an open-ended question, asking for a general response about the speaker's areas of knowledge.

In terms of the difference between the two questions, "Do you know what?" is more focused on a specific topic, while "What do you know?" is broader and asks for a more general response.

3. Both answers are correct, but they have different meanings:

3-1. "I go to a dram club." This answer implies that the person goes to some kind of club that is related to "dram," which may not be a widely known or specified club.

3-2. "I go to the drama club." This answer implies that the person goes to a specific club called the "drama club," which is more common and widely recognized.

The correct answer depends on what the person intends to communicate - whether they go to a club related to "dram" in general or a club specifically named "drama club."

4. The sentence "I am Bora, your student from last year." is grammatically correct. The use of "from" in this sentence indicates that Bora was a student of the person being addressed in the past. It does not imply that Bora is still someone's student currently.

Alternative expressions with a similar meaning could be:

- "I am Bora, the student you had last year."
- "I am Bora, the student who was in your class last year."
- "I am Bora, who studied under you last year."

These expressions convey that Bora was a student of the person being addressed, without implying that Bora is still someone's student.
