2. Cambridge English Grammar in Use by Raymond Murphy. The first section on Past and present is free.(If you want to do other tenses in this app, you need to buy it.) Do the 5 exercises in Unit 6 (Past Continuous), then write a paragraph of 8 lines to say:

• how useful this was for learning English and why
• how easy the app was to use 
• how interesting the app was 
• if you would use the app again 

  I did simple past and past continues  tenses in English grammar. This is very useful for me. I confused to use these tenses before, but now I can easily use them .I did some mistakes in exercise.But it was very good. I got eight correct out of ten. I really want to use again.
