Put the words in the right order to make questions. (You here are – Are you here?)

If there is no auxiliary verb, we put do\does\did before the subject. Statement “+” : I like pizza. Mike lives in London. He went to the restaurant. Question “?” : Do I like pizza? Does Mike live in London? Did he go to the restaurant?

b. Make questions with you (know me – Do you know me?)
1 drink tea__________________________

Remember! Never put do with other auxiliary verbs! (Will you come? – NOT Do you will come?) Remember! Put only one verb before the subject (Are you playing? NOT Are playing you?) d. Make questions. (We see a sea – Do we see a sea?)

Question words
Questions with question words (how, when, where, why, who, etc) usually have the same word order as yes\no questions. (Where do you go? Who will he come with?)

e. Make questions with the words in the box.
How when where why when
1 (you come)________________________________________________________? To see you.

3 (you say “chocolate” in Russian) ________________________________________? “Shokolad!”
