1. So class, what is the different of WH question and yes No Question! 2. How to form WH Question and Yes No Question!!

1. The first different of WH question and yes/no question is we have to answer with long answer if the question is WH question. But, in yes/no question, we can use short and long answer. The second is if we want to clarify the statement, we use WH question because we use it to complete the statement, there is an element we must get grid of. In yes/no question, we don't complete the statement because it may be complete or we don't want to know more information.

2. We always use auxiliary verb in the both of question. The formula is :
WH question : WH + Auxiliary Verb + the statement?
Yes/no question : Auxiliary verb + the statement?

Example : 
1. Mr. Ari teaches chinese in 12 Junior High School of Makassar

WH : - Who does teach in 12 Junior High School of Makassar? (Subject Element)
- What does Mr. Ari do in 12 Junior High School of Makassar? (Verb Element)
- What does Mr. Ari teach in 12 Junior High School of Makassar (Object Element)
- Where does Mr. Ari teach Chinese? (Place Element)

Or, we ask the statement that does not exist
- When Mr. Ari teach Chinesein 12 Junior High School of Makassar? (Time Element)
- How Mr. Ari teach Chinese in 12 Junior High School of Makassar? (Manner Element)
- Why Mr. Ari teach Chinese in 12 Junior High School of Makassar? (Cause Element)

Yes/No question : Does Mr. Ari teach english in 12 Junior High School of Makassar?

Maaf kalo salah

1. -Wh questions (Who, where, whom, what, etc.) then the answer will be   sentences that answers the question
ex: What is he doing?
ans : He is eating
- Yes/no questions then the answer will only be "Yes" or "No"

2. -To form WH question, just simply use the question word that are prefixed by wh like : what, where, how, when, which, who, whom, whose, and why.
-To form Yes/no questions, the question word will be like : do, does, did, will, etc.
SEMOGA BERMANFAAT~
