But these days, fewer teens are celebrating these events.According to a study published in the joumal Child Development, fewer American teens are doing “adult”activities like driving and working.

Perhaps too much homework is to blame(責(zé)備). But that’s not the truth.“Teens usually spend less time on homework now than they did in the 1990s,” The Atlantic reported.

Child Development expert(專家) Jean Twenge says technology may be to blame. In her research, she says that today's teens are different from past generations (幾代)because they are the first generation to grow up with social media and smartphones.

What kind of effect does it have on how quickly kids grow up? More time spent playing with technology means less time spent on other things. This may explain why fewer kids are interested in“adult”activities these days.

In the past, getting the first driver ' s license was seen as something “cool” that could impress one's friends. But today, kids would rather stay at home and play with their phones. If they aren’t spending time with their friends, they aren’t interested in that“cool”license, according to the Chicago Tribune.

It is hard to say growing up more slowly is good or bad. But kids should have more time for social and emotional(情感的) development. It is necessary for achieving success later in their life.

81-year-old James Harrison, also known as the man with the golden arm, not only has given his blood, but also has been doing that for about 60 years! When Harrison was young, he was in hospital for a few months.The blood he received saved his life so he decided to give blood.
