1. There’re plenty of good things about social media, but also many potential dangers to teens from them. Teens don’t always make the smartest choices when visiting social networking sites, and sometimes this can lead to problems. |
2. More than half of American teens visit social networking sites daily and the number of American teens doing that is increasing. Social media can be distracting and can negatively impact learning. Studies found that students in middle school, high school and college who checked social media at least once during a 15-minute study period achieved lower grades. |
3. These statistics about American teens highlight the dangers of social media: 17% of them say they’ve been contacted online by someone they didn’t know in a way that made them feel scared or uncomfortable. 30% of them say they’ve received online advertising that was inappropriate for their age. 39% of them admit lying about their age to gain access to some websites. |

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.
Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology（神经生物学） of forgetting can be just as important to our decisionmaking as what our minds choose to remember.
“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(转瞬即逝) is as important as persistence in memory systems，” their study in Neuron states.
Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神经元) in our hippocampus(海马体), which have the power to overwrite existing memories that are influencing our decisionmaking.
“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision，” Richards told Science Daily.
If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.
When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.
“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life，” Richards said.
If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.
These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.
Title：Being Forgetful Might Actually Mean You're 1.
Introduction | Recent research proves that being forgetful can be a strength, for forgetting and selective memory are of 2.importance in our decisionmaking. | |
The goal of memory | People take advantage of memory to make good decisions rather than 3. information. | |
4. of being forgetful | It helps us forget outdated information. | ●Making wise decisions involves the existing memories making 5.for the latest information. ●Meanwhile, too much contradictory information in memory can do harm to our decisionmaking. ●Exercising helps increase neurons, contributing to our 6. decisionmaking. |
It helps us see the big 7.．
| ●After 8.the information it gets, the brain chooses to focus on the key points, occasionally forgetting unimportant past details. ●Whether to remember or forget particular stuff is 9.by the degree of the consistency of the environment and the 10. of things reappearing later in life. | |
Conclusion | Our brains are working smarter when aiming to remember the right stories, not every story. |
