2 . If you use “123456”, “password’’ or “qwerty” as a password, you’re probably aware that you’re at the risk of being attacked by hackers (黑客). But you’re not alone.
The findings show password choices are often attached to cultural references.
Choosing long and complex passwords remains the main authentication mechanism (身份验证机制) for computers and network-based products and services. But we know people continue to choose weak passwords and often don’t manage them securely.
To overcome the security issues linked with password-based authentication systems, researchers and developers are now concentrating on creating authentication systems which don’t depend on passwords at all.

3 . When you are online, you can be anyone or anything. You can create your own image and a new personality. These digital identities are known as avatars (化身).
The first simple 2D avatars appeared in role-playing computer games in the 1980s. Yet, very few people knew that future avatars would have such a wide variety of forms and uses. By the late 1990s, they had been used in web chats.
When people started creating their own avatars, they discovered that they were going to have the power to create new identities that did not look or act like their real selves at all. They could dress their avatars in fancy clothes, or they could try being someone of the opposite sex. When Internet users realized that their avatars would be seen by many people, not just their friends, they started having more than one avatar. Avatars let you express yourself and they give you lots of room for creativity.
Of course, the avatar you choose says a lot about your personality. If your blog avatar is a picture of a cute cat, your message is “like relaxing and having fun”. Well-known cartoon characters or laughing monkeys say “I’m a really funny person”. Most people create avatars that have similar features to their personalities and that look more or less like them and act like them. However, people obviously make their avatars look better than they do in real life.
Nowadays, avatars are everywhere and very useful. In most web chats, people choose an avatar from a selection of ready-made images or create their own images. You can also use avatars that move around and talk when you type in your message.
Despite the advantages of avatars, the use of avatars has also caused a few concerns. Some users 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 a risk, as people can use avatars to cheat others online.
1. What can be inferred in paragraph 3?A.People’s new identities were very powerful. |

A.A diary. | B.A guidebook. | C.A scientific fiction. | D.A magazine. |
4 . Web 1.0 is often referred to as a “read-only Internet”. All its content was created by webmasters. Users could not interact with the content or add content themselves.
In the age of Web 2.0, the Internet became interactive. Websites allowed users to communicate with each other. So Web 2.0 is also known as the Social Web. Web 2.0 led to a big jump in technology development. It changes the way we work, socialize, create and share information and ideas. In Web 2.0, while users can create content, they don’t own it and cannot control it. The platforms can easily block or remove the content without the permission of the creators.
So Web 3.0 is coming. Web 3.0 is a concept of a new generation of the Internet. In contrast to Web 2.0, where most of the data is stored in corporations, such as Google, Amazon, Facebook, Apple, etc., Web 3.0 data will be decentralized (分散). Web 3.0 will create platforms that nobody controls but everyone can confirm.
Let’s see what important changes we may expect. No third party is required. For instance, the use of cryptocurrencies (加密货币) ends the need for banks because all financial deals take place directly between the two parties using cryptocurrency. In addition, Web 3.0 will make it much more difficult for Internet attackers to access sensitive information. Besides, Web 3.0 makes businesses directly accountable to their consumers. Businesses may apply this openness to their consumers to develop relationships of trust and loyalty. Plus, the information is accurate since data saved on blockchains (区块链) cannot be changed.
The new Internet promises to build a “global village”, a world focused on interpersonal interaction throughout the world, which will contribute both to the development of technology and business, and the promotion of personal happiness.

C.It will make efforts to develop the world agriculture. |
D.It will narrow the distance between humans on Earth. |
A.The Coming Web 3.0 | B.The Ages of Social Web |
C.The Famous Internet Giants | D.The Diverse Cultural Global Village |
5 . It’s difficult to determine whether social media is safe enough for children’s mental health, according to a new report from Dr. Vivek Murthy.
Although there are some benefits, social media use brings “a great risk of harm” to kids. “We’re in the middle of a youth mental health crisis, and I’m concerned that technology companies are contributing to it,” Dr. Murthy said.
“It is generally believed that parents and kids should be responsible for managing social media, despite the fact that these platforms are designed to increase the amount of time that our kids spend on them,” he said. “So that is not a fair fight. It’s time for us to support parents and kids.”
Up to 95% of kids aged 13 to 17 report using social media, with more than a third saying they use it “frequently”. And although 13 is commonly the minimum(最小的) age to use social media sites in the US, the report notes that nearly 40% of kids aged 8 to 12 use the platforms, as well.
One study of 6,595 US adolescents between ages 12 and 15 found that those who spent more than three hours a day on social media had twice the risk of symptoms(症状) of depression and anxiety as non-users, the report notes. It also cites(引用) studies that found reducing social media use led to improvements in mental health.
Murthy says he hopes the report will encourage measures before it is too late. “Independent researchers tell us that they have a hard time getting the information they need from technology companies about the health effects on kids,” he said. “Social media companies should be responsible for protecting children as other industries are. As to other products that kids use, we take the approach of safety first. We need to do it here, too.”
1. What causes children’s mental problems according to Murthy?A.Risk of addiction. | B.Parents’ management. |
C.Technology companies. | D.Children’s learning stress. |
A.By listing data. | B.By providing facts. | C.By giving examples. | D.By explaining causes. |
A.Public opinions. | B.Previous studies. | C.Field observation. | D.Family relationships. |
A.Health effects of social media on kids. | B.Safely for kids concerning all products. |
C.Immediate action to protect the children. | D.Difficulty in getting the needed information. |

10 . Imagine having the opportunity to sing together with hundreds of other people while you are at home alone. You can do this in a virtual choir. Virtual choir members record themselves while they perform alone on video. These videos are uploaded onto the Internet, and then they are put together into one video that you can see online—a virtual choir. Anyone can take part in a virtual choir from anywhere—all you need is a video camera and an Internet connection. A virtual choir enables people to add their voices to those of other individuals and become part of the global community. It has proved to be a positive influence on the lives of many people.
The virtual choir was the idea of award-winning composer and conductor Eric Whitacre. He fell in love with Mozart’s classical music when he sang for the university choir. Moved by this music, he said, “It was like seeing color for the first time.“ Over ten years after his graduation, Whitacre’s original compositions began to become quite popular among choirs and singers. This led to the creation of the virtual choir.
In 2009,Whitacre received a video of a girl who was singing one of his works. Inspired, he asked his fans to make videos, which he then joined together into one performance. His first virtual choir, “Lux Aurumque”, had 198 singers from 12 different countries. It has received millions of views on the Internet. Since then, the virtual choir has become a worldwide phenomenon. Whitacre’s next effort was the virtual Youth Choir for UNICEF, which was first seen on stage on 23 July 2014 in the UK. Altogether, 2,292 young people from 80 countries joined in to sing Whitacre’s song “What If”.
The virtual choir is a wonderful way for people around the world to sing with one voice and thus make the world a better place.
