• Questions with Noun Clauses

• 
• Remember, use the auxiliary verb do to form yes/no questions.

  do + subject + verb + object?

  - Do you know John? 

  
  

  Because noun clauses function as the direct object in a sentence, simply replace the object with a noun clause to form a question with a noun clause. 

  
  

  Do you know that there are over 16,000 endangered species
• 
  

• Did you understand what the environmentalist said about water conservation?	Do you agree that greenhouse gases are contributing to climate change?
  Does he remember what we learned in biology class about habitats and ecosystems?	Did you hear which species made it onto the endangered species list this year?
