“Can I borrow the car, Dad?”

“Not   1   you finish mowing the lawn(除草).”

“But I have to go to work!”

Such conversations often happen to American   2  . A job, a car, spending money, walking the dog and mowing the lawn, this isn’t just the   3   life of middle age but, in fact, this is the life of many American teenagers.

In the US, it is common for kids as   4   as 14 to hold part-time jobs.

They might save up their money to buy a car and, at 16,   5   it. But this kind of independence (独立) isn’t always fun. US kids have to take care of themselves and their younger brothers and sisters so that they are ready   6  alone.

The average (平均的) age of a high school graduate in the US is 17. Traditionally, a US student graduates(毕业) in June and  7   out of his or her parents’ house by September. Of course, one must be ready for this.   8   a small amount of homework, US high school students have more time for working and   9    adult(成人) responsibilities (责任).
