In the classroom

There are two kinds of questions:

1. yes-no questions:

You put am / is / are at the beginning of the sentence:
Man setzt am / is / are an den Anfang des Satzes:

statement:	I	am	watching	TV.
→ question:	Am	I	watching	TV?
statement:	He	is	reading	a book.
→ question:	Is	he	reading	a book?
statement:	We	are	doing	our homework.
→ question:	Are	we	doing	our homework?

You answer to a yes-no question with a short answer. There is NO verb + ~ing in a short answer!
Man beantwortet eine Ja / Nein-Frage mit einer Kurzantwort. Das Verb + ~ing wird in der Kurzantwort nicht wiederholt!

Yes,	I am.
	you / we / they are.
	he / she / it is.

(no short forms possible!)

No,	I'm not.
	you / we / they are n't.
	he / she / it is n't.

(short forms necessary!)

2. Wh-questions:

Put the question word (who / where / what / why / when) at the beginning of the question:

→ question:	WHAT	am	I	watching	?
