Mickey is only 12-year-old (simple present tense), but he has finished high school (present perfect tense) and is currently studying robotic engineering in MIT (present continuous tense). He has been working hard on his project (present perfect continuous tense) to create a mind-controlled exoskeleton that enables the user to move around by 'ordering' the exoskeleton to do so. He believes his invention will be very helpful to mankind (present future tense), especially to disabled people who have lost their body motor control. He is very determined to develop this machine and hopes that those poor people will be using the machine in the near future (present future continuous) and thus be able to have a better life. He has set a strict project plan and aims to finish it within 2 months time. He projects that the control center helmet will have been ready for use by the end of this month (present future perfect tense), and hopefully people will have been using the machine by New Year (present future perfect continuous tense).

His quick progress is not of unfounded reason. When he was 5 years old, he lost his use of legs (simple past tense) after he had been severely injured in a motor accident (past perfect tense). He was accompanying his mother (past continuous) in the backseat of her car when a truck lost control and hit the car from the rear. Her mother regretted the accident very much, saying he would have been safe and sound at home (past future perfect tense) if she hadn't decided to bring him along. Being a single parent, she had been raising Mike alone. (past perfect continuous tense) It was certainly a difficult time for the mother and son
