二、重点语篇清单

语篇一

Avatars are digital identities that you use to represent yourself online. You can choose an avatar from a selection of ready-made images, or create your own images. Although avatars haven’t been around for long, they are widely used.

Avatars let you express yourself and give you lots of room for creativity. But the use of avatars has also caused concerns. Some users worry that they are spending too 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, many people see avatars in a more positive light.

虚拟形象是你在上网时使用的可以代表你的数字身份。你可以从现成的图片中选择一个 作为虚拟形象，或者创建自己的图片。虽然虚拟形象并没有出现多长时间，但它们已经被广 泛使用。

虚拟形象让你可以表达自己，还给你很多创造空间。然而虚拟形象的使用也引起了一些 担忧。一些用户担心他们在虚拟世界中花费了太多时间，以至于开始害怕在现实世界中与人 见面。使用多个虚拟形象也可能会带来风险，因为有人可能会在网上使用虚拟形象来欺骗他 人。然而，很多用户则以更为积极的态度看待虚拟形象。

语篇二

Some people believe that while the Internet can bring people closer together, it can also harm friendships. Talking online is no replacement for face-to-face contact—images really cannot replace real-life smile or hug. Communicating through a screen makes it more difficult for children to concentrate or show kindness to others. Instead of having proper conversations with their friends, some people are only concerned with their online popularity. We know that the number of “likes” or followers cannot compare to having long-term and rewarding friendships. In addition, a lot of the content posted on social media is shallow or trivial. While it can connect you with other people who use a smartphone, face-to-face contact with others is important to help you maintain healthy relationships. This argument is thought-provoking because it shows that people still need face-to-face communication with others today.

一些人认为虽然互联网可以让人们更亲近，但它也会损害友谊。网上聊天并不能代替面 对面的交流—图片当然无法替代现实生活中的微笑或拥抱。通过屏幕交流会使儿童更难集中 注意力或对他人表示善意。一些人不再和朋友好好地交谈了，他们只关心自己网上的人气。 我们知道有多少“赞”或关注者无法与拥有长期和有益对友谊相比。此外，很多发布在社交 媒体上的内容都很肤浅或琐碎。虽然你可以和另一个有智能手机的人进行线上交流，但是面 对面交流是对于保持健康关系是很重要的。这一论点发人深省，因为它表明现今我们仍需面 对面交流。
