7 . Where am I? What am I doing? If you're one of my 500 friends online, you'll always be the first to know. My phone and laptop are never out of touching distance, so I'm endlessly checking through all my social networking apps - whether I'm having a coffee, on my way to school, watching TV. . . even when I'm in the shower. I have a never - ending flow of messages and updates from all the people I associate with online. Yet the truth of the matter is: I feel lonely

I'm not the only person who feels this way. According to research, over two-thirds of young people find it easier to make friends online than it is “in real life”. I'm a shy person, but I'm wired up (上线) every day, like most of my friends. On the surface, phones bring us closer together. But in reality, my mind is always a million miles away.

I often feel depressed, dissatisfied and alone. Since I spend so much time socializing online, I even become a procrastinator (拖延者) . I keep postponing things that are important in my real life: homework, tasks, connecting with my friends and family members in a meaningful way. It's funny that my friends and I chatter away online so much, but we end up having nothing to say when we meet.

What is rally worrying is that no one I know, including myself could go cold turkey. I can't even imagine going without social networking for a week - think of all the important appointments, invitations and news updates you would miss! Alcoholics (酗酒者) who want to quit drinking can avoid drinks, but how do we give up our phones? After all, I need it for my studies because my teachers and classmates need to contact me at any time. So, that's the problem with social networking. We're hard-wired in, but we're more disconnected than ever.

8 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Twenty years ago, the idea of sharing our lives so     1     (open) with the world was unheard of. However, for young people today it     2     (consider) completely normal to share pictures of their lives and interact online every day

However,     3     concerns people is that too much time on social media may have some negative effects. Researchers measured people's attitudes and feelings before and after visiting social media sites. They found that the more time people spent on social media, the more unhappy they became.   

There are a number of reasons for this. When     4     (surf) the social media, people often see photographs and stories showing beautiful holidays, fun parties and fashionable clothes. People rarely post negative stories or bad pictures,     5     can be misleading. For those looking at these pictures and comparing them to their own lives, they can end up feeling sad and depressed. They might think their lives are     6    (bad) in comparison. Even for those people who post positive stories and pictures, they too can feel stressed and worried.     7     number of "likes" and comments on their posts can make them anxious about their     8     (popular). Of course, there is also the problem of "cyber bullying".   

We don't have to disconnect from the Internet     9     (live) a happy life, but we should realize that the pictures we see and stories we read are only part of a bigger picture. If we can do that, we can protect     10     (we) and enjoy our lives.

9 . 阅读下面短文，在空白处填入一个适当的单词或括号内单词的正确形式.

The Internet has brought us great convenience. To    1     certain extent, we can hardly live without it. However, it    2     (raise) all sorts of questions, too. The following guidelines may show you how to live better in the digital world.

Above all else, you should use the Internet in a safe way. Before visiting a web page, you should always check for signs that warn people    3     danger. Another tip is to keep your    4     (person) information private, your address and email account    5     (include).

You also need to show respect when    6     (communicate) with other online users. But if some users make you feel uncomfortable online, you have rights to cut off contact.

10 . Researchers have been trying to uncover the cause of a steady decline of drug and alcohol use in teens. Some suspect it’s due to anti-drug campaigns or the decline of cigarettes as a gateway drug. But another theory has begun to surface. Is a new drug replacing the old ones? Are smart phones taking their place?

I noticed that using my smart phone took away so many life experiences. I hadn’t minded before when my own phone could distract me, but now I felt annoyed when my friends or family used their phones when we were together. Sure it was uncomfortable at first, not having a clutch (紧握) to fall back on when I didn’t feel like talking.But we shouldn’t use our devices as the universal conversation avoider, or as our distraction from the discomfort of human interaction. How can we learn to interact when our phones are on hand at all times to prevent ourselves from doing so?

Still, smart phones can sometimes be wonderful tools. They allow us to take beautiful photos and help us connect with old friends and maintain long-distance relationships. They allow us to have an endless amount of information at our fingertips, and give us directions to whatever destinations. But we must consider how every tool smart phones provide us with can also influence our lives. Not only does smart phone and screen use have an effect on relationships, it can also shape an individual and the brain. Studies have shown that excessive Internet usage can cause increased depression, loneliness, and anxiety in adolescents.

So my advice to teens who feel the same way as I do? My decision to go without a phone was definitely extreme, considering our generation. So try ditching your phone for a week. Observe how it affects your relationships, your mood, and your presence. You just might end up feeling less stressed, happier, and more connected.
