The digital identities, 【小题1】 (know) as avatars, are a key part of how people use the Internet to communicate and express 【小题2】 (they).

The first simple 2D avatars 【小题3】 (appear) in role-playing computer games in the 1980s. Yet, very few people knew that future avatars would have such a wide 【小题4】 (vary) of forms and uses. People had the power 【小题5】 (create) new identities that didn’t look or act like their real selves at all. One person could have several avatars.

The avatar you choose says a lot about your personality. However, nearly all avatars are tall, young and nice-looking, so people 【小题6】 (obvious) make their avatars look better than they do in real life.

Nowadays, avatars are everywhere. The avatars in online worlds can talk, walk and fly around, meet people, go shopping and attend classes.

Of course, the wide use of avatars has led 【小题7】 a few concerns. Some users are concerned that they are spending 【小题8】 much time in virtual worlds that they are becoming afraid of meeting people in the real world. The use of several avatars can also be a risk, as people can use avatars to cheat others online. However, other users view avatars in a more positive light. They look forward to a time 【小题9】 their avatar will act like a real person and travel around bigger, 【小题10】 (exciting) virtual worlds.

The Internet can help develop friendships in many ways. Firstly, the Internet makes communication much more convenient. You can stay in touch【小题1】friends no matter where you are or【小题2】you are doing. You can be in contact at home and also when you are on the move,【小题3】(use) a smartphone, a tablet or a computer. Secondly, the Internet has also made communication more fun. We all know that【小题4】(tradition) ways of communicating, like letters and phone calls, can be limiting and take time.【小题5】, you can share photos, videos, news stories and websites with your friends online. You can give a brief response to a message with an emoji or a picture. There are so many online tools you can use【小题6】(be) creative! Thirdly, online communication can actually bring people closer to each other. Nowadays, your friends are just a click away. Whenever someone【小题7】( need) help, friends from all over the world can【小题8】(immediate) provide useful suggestions or information. This makes friends feel【小题9】(love) and cared for. To me, this is a very thought-provoking argument, as it points out the【小题10】(benefit) of online friendships. As Eileen Kennedy-Moore, an authority on the subject, points out, online friends “fill holes real-life friends can’t”.

Mobile phones have taken over our modern world. These small computer-like phones can access the Internet, do countless【小题1】 ( task) through applications, and of course make calls and send text messages. The major benefit of 【小题2】 (have) a mobile phone is that it is easier to express oneself through communication and creativity, to be safe, and to connect to the Internet.

Communicating 【小题3】 loved ones, colleagues, friends and more has never been simpler. By allowing instant access to any desired destination across the globe, mobile phones 【小题4】 (change) the landscape of communication so far.【小题5】 (global), cell phones are important in day-to-day life. Besides the ease of communication, expressing oneself creatively has also never been so straightforward. With our applications, we can easily draw, take photographs, write, edit, paint, make videos, and more.

Mobile phones are also 【小题6】（fantasy） for keeping us safe. Mobile phones allow us to call for help, aid us in finding our cars and give us the opportunity 【小题7】 （employ） GPS to make sure we do not get lost. The more applications you have, the 【小题8】 （great） chance you are safe. You might have a flashlight app or 【小题9】emergency call app. They can help you 【小题10】a difficult situation arises a lot.
