1 . Thirteen-year-old Kaylee has a lot of friends — 532, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Kaylee’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not Words With Friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platforms (平台).

In fact, in many ways, online communication can make friendships stronger, “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual words, we will have little time for our real-world friendships.” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need someone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

I will share a true story that happened a couple of days ago to you. One of my classmate bought a bag of snacks from a food store. A few roommates were then invited to enjoy snacks. Unluckily, all of them got poisoned and had a stomachache with our faces pale. They were quick sent to a nearby hospital. Doctors examine them and gave them some medicine. They were out of dangerous soon before taking the medicine. This accident should make us to realize the seriousness of the food safety. I strongly suggest that the whole society pays more attention to this problem.

Students need enough sports and activities to keep fit and relax, and in some schools students are not giving enough time to do outdoor activities. Teachers ask students to spend most of their time at studies. But if students feel tired, they can’t pay attention to that they’re studying. They will be in a bad health. It’s also not good for his studies. In my opinions, it’s important give students enough time to do outdoor activities. Then they will enjoy better health and work hard. So please pay more attention to student health and growth.
