Peter __________ (KNOW) that his mother could give him a hard time. She would be much _________ (STRICT) with him than with the other students. But Peter __________ (NOT/MIND) that. He wanted to become a very good driver, which meant he should know the car inside out. His mother said she __________ (ALLOW) him to join her course if he promised to fulfill all her requirements. And Peter agreed. In the morning he learnt the traffic rules in his mother’s classroom and in the evening he was in the garage studying what cars _____________ (MAKE) of. “It’s really important to understand how the engine ___________ (WORK),” Peter’s mother kept saying, “When you get your driving license, this knowledge ______________ (HELP) you to drive responsibly.” Peter didn’t understand how the technical things could influence driving skills but he listened to his mother. “You ___________ (LEARN) everything you need,” Peter’s mother said one day, “Now you are ready to take the driver’s seat.” Peter felt happy.
