Years ago, if a teenager had some problems in his life, he might write them in the diary. But now a teenager may go online and write his     1     (每日的) feelings in a micro blog(博客). Diaries and micro blogs     2     (两者都) remind the writers of what happened to them     3     (在) a certain day. But what makes micro blogs different from diaries?

One of the biggest differences is that micro blogs attract more attention, while diaries are too     4     (私人的). Nowadays people are     5     (积极的) in writing micro blogs than diaries. They want others to read the things about them as many as possible. Also, a few special or interesting micro blogs can be     6     (传播) widely and become famous. As they write more micro blogs, their fans may     7     (增加) as well. Therefore, some people may show the moments when they feel happy, some may share the     8     (幽默的) stories or experiences, and some even write     9     (小说) in their micro blogs.

If people are caring about what they write and     10     (谁) may read it, micro blogs are without doubt a good way to write about their life.

Forty years ago, my dad’s family lived in the countryside but Grandpa worked in the city, so they wrote to each other. When Grandma asked a     1     (问题) in her letter, it took her two weeks to get the answer!     2     (除非) there was something important, they didn’t send telegrams.

The telephone became     3     (受欢迎的) in the early 1990s. But my dad’s family did not have a telephone     4     (直到……时) 1998. Although it was much faster than writing letters, it was still inconvenient. Once Dad arrived home     5     (晚) because he helped a granny on his way. But he could not call his parents to tell them what happened. That made them very     6     (紧张的). This never happened again after my dad     7     (购买) his first mobile phone in 2002.

My favorite communication     8     (工具) is the mobile phone. I have used the mobile phone since my     9     (十六) birthday. It is very convenient. My parents and friends can find me     10     (任何地方) I am. However, at the same time it is easy to be broken especially when I want to be alone.

Over the past 20 years, the internet has a great     1     (影响) on our lives. The Internet makes it much more     2     (方便的) for people to search for information. For example, when we write a history report, we don’t have to go to the library. We can find the     3     (有关历史的) events on different websites. Everything we want to know can be found at the click of a button.

The Internet helps to     4     (与……有联系) us with family, friends and the world around us. Not long ago, we wrote letters by hand and waited weeks for a reply. Today, when we use QQ, we send and     5     (接收) messages across thousands of miles in a few seconds.

The Internet gives us a way to express our opinions in     6     (公开的). We share interesting ideas with other people on QQ, Baidu Tieba, blogs or forums. In addition, many teenagers choose to keep in touch with each other online instead of meeting face-to-face. People worry that this is not     7     (有帮助的) to their social communication skills. Some teenagers spend too much time playing Internet games. They may lose focus on their studies. This may     8     (使失望) their parents.

There are millions of interesting sites to visit and so many wonderful things to do online. How could we live without the Internet nowadays? But remember to use the Internet properly and     9     (明智地). Try to let the Internet be your good servant, not your     10     (主人)!

Do you struggle to leave your phone alone? Who are you communicating with when you pick up your phone? Are you using it to stay in touch with the people who     1    （真的）matter to you? Try to remember to put your closest friends and family members first. Perhaps it’s important to organize a video call with your     2    （祖父母）or a cousin who lives far away. Or maybe you use it to send a     3    （信息）to your best friend.

These communications can help build and develop your most important relationships, making things even more special when you next see each other face to face. On the other hand, you might decide to spend less of your     4    （有价值的）time on certain other people. They could     5    （包括）people you don’t know, and who aren’t as important to you.

How do you keep in touch with your families and friends? Think about it, which tool will be the first one jump into your mind? The answer is WeChat. Today, WeChat is becoming the most     1     (受欢迎的) text and voice messaging tool all over the world. It was developed by Tencent(腾讯) in     2     (一月), 2011.

Do you know how to use WeChat? It is so easy that not only old people but also little boys can learn it     3     (快地). First, you can use your phone number, QQ ID to     4     (创造) a WeChat ID. Then you can sign up to chat with your friends. If you want to send a voice message, press the “Hold to talk”button and record. With the interesting function “Look Around”, you can search for people who live nearby. “Shake” is another amazing function in WeChat. You can find a “stranger” to talk to by shaking the phone. The system will find out others who are shaking their phones at the same time and make a match.

WeChat is really a wonderful     5     (发明) that changed the world.

Do you write your own blog? Do you often read others’ blog on the Internet?

All over the world, not o    1     famous people but also many students use blogs as diaries and places. They share their experiences and ask for a    2     or help. “I w    3     my activities every day, including funny things and worries in my life.” says Lina, a 16-year-old high school student in Washington. “I like putting pictures on my blog because it can make my blog more i    4     and more people will like it. It’s a good w    5     to show my life to the world.” She has had her blog f    6     eight months. Students like writing blogs because they can write anything they want to, but don’t n    7     to spend any money.

When you start to write your blog, you will find it necessary to o    8     up your eyes to a new world. B    9     what you write down may trouble you sometimes. So use the blog c    10     so that you can keep yourself away from some trouble. The blog makes everyone’s life colourful.

When you’re bored, what will you do first? If you’re like many, the answer is quite simple: You reach for your phone. Five minutes of short videos or funny pictures seem like a p     1    break.

If that sounds familiar, a new study has bad news. Reaching for your phone is likely to leave you feeling more bored. The problem isn’t taking a break. The problem is your phone. A research shows using phones can’t     help people r     2     from their heavy work.

To figure out the r     3    between phones and boredom, the research team installed（安装）an app on the phones of 83 volunteers to find out how often they used their phones. They also asked these volunteers to keep diaries for three days, recording their level of boredom every hour “ Phone breaks were frequent （ 频繁的）： In the 20 minutes following each questionnaire, the volunteers picked up their phones 52 percent of the time. They spent an average of around 90 seconds on it   each time, ” reports   the   research team. “ The   more tired we are,   the most l     4    we are to reach for our phones. While we look to our phones to relieve（减轻）boredom, screen time seemed to i     5    feelings of boredom. The volunteers actually reported higher levels of boredom after having used their smartphones.”

The research team pointed out that phone breaks may end up being more tiring than stimulating. In other words, watching the funny videos is very nice, but it’s now w     6     the cost to your   brain in   effort and concentration. In addition, picking up your phone might remind you that you have a better choice to do something else if you don’t have to finish the tasks immediately. Both your time and effort are easily wasted.

What should we do i    7    ? Taking a walk is good exercise. Calling someone     can make your mood       cheerful. Reading a book gives your brain a fresh start. You can do many things like that. Just remember, don’t reach for your phone!
