The Internet is good for many millions of things. In today’s     1     (connect) world, it’s hard to imagine once again living in a world without the Internet. Of course, there are still libraries     2     you can get information or photo-printing stores in which you can order pictures, but the Internet has made the way we live our lives much faster than it     3     (be) in the past.

Along with the good comes the bad, though. If you’ve never thought of the Internet as a possibly-dangerous place, you need to be aware that, just like in the real world, there are some people who intend     4     (use) the Internet to harm you. Therefore, it’s important to learn how to stay safe when you’re online.

First, you should never give out the following types of information online: your full name, your address, your phone number, your birth date or your password. Of course, you will have to provide these things when you order things online, but be sure you’re dealing     5     an honest online shopkeeper.

Second, choose email addresses, screen names, and passwords     6     (careful). Make sure they don’t uncover personal information about you. For example, don’t use your real name as your screen name! Passwords should also be nearly     7     (possible) to guess.

Third, if you feel like you’re being cyberbullied (网络欺凌), whether via email, a social media website, or in a chat room online, be sure to report     8     (they) to an adult.

Finally, remember that the Internet is a large place, but it has a way of     9     (spread) things around very quickly. If you wouldn’t want a friend or parent to see something, it’s probably something you shouldn’t post from     10     beginning!

    1     (million) of young people are writing blogs (博客). Millions of others are reading them. They have been an     2     (attract) to young people.

Many popular Websites now offer free, easy ways to create personal Web pages and fill them    3     writings and pictures. Websites such    4     “Facebook” and “Myspace” are some of the most popular blog sites for young.

Blogs offer young people a place     5    (show) their writings and feelings. They can also be     6     (help) to connect young people with others. But blogs can become    7    (danger) when they are read on the Internet by millions of people all over the world.

Recent studies show that young people often tell their names, ages and where they live on the Internet. That may not be safe for them. The personal information puts them in danger when found out by dangerous people     8    want to hurt them. Students can also get into trouble when they put information about others on their blog.

As     9    result, many schools don’t allow using blogging websites on school computers. Many schools have also begun teaching parents about the websites. Parents should know what their children are doing online and help their children escape     10     (give) away personal information.

The Internet has clearly affected all     1     (level) of education by providing endless possibilities for learning. I believe the future of education is a networked future. People can use the Internet to create and share knowledge and develop new ways of teaching and learning that excite students’ imagination at any time, anywhere,     2     (use) any device. By connecting and empowering students and educators, we can speed up economic growth and enhance (增强) the well-being of society throughout the world. We should work together, over a network,     3     (build) a global learning society.

The Internet is an inexhaustible (无穷尽的) source of information. What’s     4     (much), the Internet has enabled users to move away from their former passive role as recipients (接受者) of messages     5     (give) by traditional media     6     an active role, choosing what information to receive, how, and when. The information recipient even decides whether     7     not they want to stay informed.

Today, you can use the Internet to access libraries, art galleries, news archives, and other information sources from anywhere in the world: I believe this is a key advantage in the education field. The web is a(n)     8     (amaze) resource for enhancing the process of building knowledge.

Besides its communicative purposes, the Internet     9     (become) an important tool for exchanging knowledge and education since it entered our lives; it is not just an information source, but a channel (渠道) for connecting other people and groups     10     are working on related research topics.

The World Wide Web is now more than thirty years old. Its     1     (invent), Sir Tim Berners-Lee, has spoken about his creation     2     its 30th anniversary. He said he was concerned about how people are using the Internet and its billions of websites today. He also said he is concerned about the future of the Web. He wrote a letter     3     (say)he knew many people felt unsure about whether the Web was “a force for good”. He believed it can be a force for good and can empower(授权)billions of people. He wrote that he believed governments and companies must work together to build a     4     (good)Internet.

Sir Tim had three main concerns about the World Wide Web. The first was criminal behaviour. He described it as a“mirror of humanity(人性)”     5     “you will see good and bad”. He said governments must pass laws     6    (keep)people safe. The second thing that worried Berners-Lee was how social media     7     (use)to spread misinformation. The past few years     8     (see)a rise in fake news. Berners-Lee is also worried about people’s privacy and     9     (person)information. He stressed the importance of fighting for     10     better and safer Web and keeping it free for everyone to use.

Avatars are digital images     1     represent Internet users. Very few people knew avatars     2     (have)a wide variety of forms and uses in the future when the first simple 2D avatars appeared in     3     1980s. By the late 1990s, people had used avatars in web chats. And nowadays, people can choose an avatar     4     a selection of ready-made images.

Avatars let you express     5     (you)and give you lots of room for     6     (creative). But the use of avatars has also caused a few     7     (concern). Some users worry that if they spend too much time in virtual worlds, they will be afraid of     8     (meet)people in the real world. Avatars can also be used to cheat others online.     9     , many people see avatars in a more positive light. They hope that their avatars will act like a real person and travel around     10     (big), more exciting virtual worlds in the future.

Does the Internet help or harm friendships? Different people have different opinions. Robert thinks talking online is no     1    (replace) for face­to­face contact. Communicating through a screen makes     2     more difficult for children to concentrate or be kind to others. Social skills enable children to develop lifelong friendships. What's more, the Internet     3     (make) people self­centred. They are only concerned with their online popularity. He also thinks friendships are built on the basis of trust. Going online can be particularly dangerous for people who are easily     4    (influence) by others.

But Cathy holds the opposite opinion. She thinks the Internet makes communication more     5    (convenience) and more fun. People can keep in touch     6     friends wherever they are or whatever they are doing. There are also so many online tools people can use to be creative. In     7    (add), online communication can     8    (actual) bring people closer to each other. Whoever needs help can immediately get some useful     9    (suggestion) or information from all over the world,     10     makes friends feel loved and cared for.

Don’t brag(炫耀), but be proud of what you have done. These two pieces of advice     1     (be) tough to balance before Facebook existed. Even today’s share-it-all social media haven’t made     2     any easier. We are     3     (able) to draw a line between a humble bragging and a straight-up bragging. But we certainly know that oversharing doesn’t do your friendship any favors.

Social media like Facebook bring us     4     (convenient). Meanwhile, they can put us     5     danger of oversharing. Once upon a time, only your family and close friends would be there     6     (see) you eagerly open presents on Christmas morning. Now the photo     7     you take on your iPhone will likely become a touch-up Instagram in about 15 seconds. Maybe you just post it subconsciously. But your sharing behavior could     8     (easy) be considered annoying or even narcissistic(自恋的).

To post or not to post? Maybe we should all be asking     9     (we) the question before hitting the share button. As our personal fame grows alongside our social media presences, so     10     (do) the number of people we could potentially(潜在地) impress or bother.

While the Internet can bring people closer together, it can also harm friendships. Talking online through a screen makes it harder for people to concentrate or show friendliness     1     others. As is known to all, important social skills are developed through direct contact with other people. Besides, the Internet     2     (make) people self-centred. Some people are only concerned with their online popularity. They pay too much attention to the number of “likes” or followers,     3     wouldn’t contribute to meaningful relationships. Additionally, due to lack of basis of trust, online relationships can be particularly     4     (danger) for people who are easily influenced or too trusting.

People have different ideas about how the Internet     1    (affect) friendships.   

Some people think the Internet can harm friendships. Firstly, talking online is no     2    (replace) for face-to-face contact-images really cannot replace a real-life smile or hug. Secondly, the Internet can make people self-centred-not thinking of anyone or anything but themselves. In addition lots of the content     3     (post) on social media is shallow or trivial. Thirdly, online relationships may not be     4     they appear to be. Going online can be particularly dangerous for people     5    are easily influenced or too trusting. In my opinion, face-to-face communication is the best way     6    (maintain) healthy relationships.

Others believe the Internet can help develop friendships in many ways. Firstly, the Internet makes communication much     7    (convenient). No matter where you are or what you are doing, your friends can contact you. Secondly, the Internet has also made communication more fun. You can share photos videos, news stories, and websites     8     your friends online. Thirdly, online communication can actually bring people closer to each other. Whenever someone needs help, friends from all over the world can     9    (immediate) provide useful suggestions or information. Finally, I believe the Internet brings people closer together and makes communication with friends more convenient and     10    (interest).

Avatars are digital     1     (image) that you use to represent yourself online. The first simple avatars appeared in role-playing computer games in the 1980s and by the late 1990s they     2     (use )in online chats. People started     3     (create) their own avatars that didn't look or act like their real selves. Avatars let you express     4     (you) and they give you lots of room for creativity. Most people create avatars     5     have similar features to their personalities and that look more or less like them and act like them. In most web chats, people can choose an avatar     6     a selection of ready-made images, or create     7     (free) their own images. But the use of avatars has also caused a few concerns. Some users are     8     (worry) that they are spending so 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     9     risk, as people can use avatars     10     (cheat) others online. However, many people see avatars in a more positive light
