1 . Since terrorist attack in 2019 that killed 50 people in New Zealand was livestreamed on Facebook, many of the negative effects of social media have begun to be known. So far, it’s not looking good.
Not that social media is bad in nature. It does not necessarily cause mental health problems. What it is doing, however — especially in young people, a new study argues — is increasing the number of cases of young people’s depression (抑郁) and suicide (自杀).
The new study, led by psychologist Jean Twenge at San Diego State University, has researched the effects of technology and social media on the teenager brain. For this study, Twenge and her partners researched data (数据) from 2005 to 2017. They wanted to know what age groups suffered more from depression. Chance of mood disorders (紊乱), they write, “generally becomes less with age.” In this date range, depressive cases increased by 63 percent among young people aged 12 to 17, and 52 percent among young adults aged 18 to 25.
There are two tendencies that appear to be causing this problem.
According to the study, the increased use of electronic communication and digital media during this time period may have changed ways of socializing enough to affect mood disorders and suicide-related results. For example, people who spend more time on social media and less time with others face-to-face report poorer health and are more likely to be depressed.
Tied into increased screen time, which could lead to being affected by cyber-bullying, are sleep issues. Sleep duration is decreasing among all age groups, but especially young adults during a time in life when they need it the most. Lack of sleep has been linked to mood disorders, suicidal thoughts, and suicide attempts.
Using the technology for good is one step forward. But another would be to put the phone down more often. If you’ve only grown up in a world viewed through a screen, learning that other world — namely, the real one -— exists might seem impossible. Therefore, some distance is feeling more necessary day by day.

4 . Today it is common to see people who walk about with colored wires hanging from their ears wherever they go. They move about in their personal bubbles, sometimes unaware of what’s happening around them. Are you one of “them”?
For me, walking around in my own personal bubble is perfect.
Suppose you’re at work, you don’t want anyone to break your concentration.
Pretty soon, not only will we have pretty colored wires hanging from our ears — but also our brains will be directly plugged into some new high-tech instrument. We’ll be in a virtual (虚拟) world, communicating with everyone else, or choosing not to, as we like.
In the end, there is a thin line between using technology as a tool for making life better and being a slave to it! It’s so strange — suddenly,

6 . As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.
In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.
In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”
According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

7 . Johnny Smith was a good math student at a high school. He loved his computer. He came home early every day, then he worked with it till midnight. But Johnny was not a good English student, not good at all. He got an F in his English class. One day after school Johnny joined his computer to the computer in his high school office. The school office computer had the grades of all the students: the math grades, the science grades, the grades in arts and music, and the grades in English. He found his English grade. An F! Johnny changed his English grade from an F to A. Johnny' parents looked at his report card. They were very happy. "An A in English!" said Johnny's Dad. "You're a very clever boy, Johnny."
