In which school subject can you learn about some products in our lives?
 
?
 
I am always confused between using our life or  our lives ?
 
and is this sentence correct:
Student will be able to learn the use of the passive?
I have another question please
What is the correct question should be asked when we ask students to hear the sound and guess what is the sound?
Can we say: " What do you hear? "
or what should we say?
 
 
Best Regards,
Pretty
