Nowadays, WeChat is getting more and more popular all over the world. One of its fantastic features (功能)     1     (be) video calling. With     2     feature, people can see each other’s faces and expressions in real time. I often make video calls to my English friends through WeChat. It is not only an     3     (enjoy) experience, but also a great way to practice my English. I think I speak English     4     (good) than before.

WeChat truly makes communication more vivid (生动).     5    , it brings us some problems as well. People put their stories and photos on WeChat, but some of them may be not true. People can be cheated (欺骗) by such false messages     6     (easy). What’s worse, some news even asks people     7     (send) it to others. When the news is widely spread (传播), it will cause unnecessary fear.

Some people     8     (like) certain aspects of WeChat, such as boring news or annoying messages. But WeChat still offers a lot of convenience (便利). As a     9     (say) goes “Seeing is believing.” I am thinking about     10     (use) WeChat more wisely on my phone in the future.

Cell phones have been increasingly     1     (流行的) in China these days. Many college students even high school students, have cell phones. Some even can’t live without them.

Chongqing Three Gorges University held an activity     2     (命名) “Cell Phone Ninja”. They would like the students not to use cell phones for 21 days. It was really a challenge for most students. But many of them wanted to face it as     3     (勇敢地) as they could because it was so meaningful.

The activity started on     4     (四月) 12th. Each student who took part in it got a bracelet. Whether the students used cell phones or not, there would be a photo on the     5     (屏幕) of the bracelet. After the last class of each day, the students sent the photos to the school’s     6     (公众) WeChat.

According to the teachers in the university, the students who     7     (完成) the task successfully would get a present. In fact, the activity was not a competition     8     (在……中间) students. It depended on students themselves to make the     9     (决定). The teacher hoped that this activity could not only help students from better study habits but also become one of     10     (他们的) most unforgettable experiences.

Sometimes what we post on our favorite social networks can have some consequences（后果）we didn't expect. One weekend, 20-year-old James Miller posted on his Facebook page that his job was “soooo boring”. When he got to work on Monday his boss told him to clear his desk and get out. He gave him a letter, too. It said: “    1    , we understand you are not happy with your work. We think it is better for you to look for something that you find more interesting.”

    2    and that things like this could never happen to them. A study shows that last year alone, more than three million young people worldwide got into trouble because of their online activities.

Here are some important tips. None of them can guarantee（保证）100%Internet security, but all of them will help you to be safer online.

Rule 1: Share with care!

Not everyone will like what you write on Facebook or Twitter.    3    . You can never completely control who sees your texts, your pictures, or your videos. Before clicking “post”, everyone should ask themselves two questions: “How will I feel if my family or teachers see this?” and “How might this post be bad for me in three, five or ten years from now?”

Rule 2: Be polite when you write!

Imagine someone is unfriendly in real life. You don't like it, right? Well, the same is true of online communication. Politeness matters, and anyone can be polite.    4    . DON'T USE ALL CAPITALS! If you feel angry while writing a message, wait a bit. Read it again later and then send it.

Rule 3:    5    !

Don't share your passwords with anyone. Don't post your home or email address online. Don't forward rumours（谣言）about other people, and don't say negative things about them. If you get messages like that or see them online, talk to an adult you know.
