1 . Facebook Is a Big Waster
During the first decade of the 21st century, a popular and new word has come into our vocabulary — Facebook. This is the most popular social networking website on the Internet.
In spite of the benefit it does on common people, it is true that this social network is a big waster. There are about 350 million active users on this website and 67% of them are between the ages of 13-25. More than 35 million users update their status every day.
The highest age group who use Facebook are teenagers. Most of them keep the website running whenever they are using the computer, if they aren’t in school or when they aren’t asleep. Facebook is just changing the new generation of youngsters unconsciously. The teenage life is one of the most important stages of life.
Facebook is also where people can see the gossip among their friends, virtual arguments, relationship status and updates, who is in whose “top friends”, you can become a fan of anything, join groups, post pictures and videos, play childish games, invite friends to parties or events and a lot more. Generally, all these would just disturb people into living life to the fullest. It’s not just teens who become addicted, even grown-ups do. An average person spends about 55 minutes on Facebook.
A.And 2.5 billion photos are added each month. |
B.Wasting it on Facebook is not encouraging in any way. |
C.This statistic isn’t that bad but some people spend about 3-5 hours. |
D.It is time people should take a break from Facebook once in a while. |
E.As a result, the average Facebook users have 130 friends who they share links with. |
F.Usually, when people hear the words “social networking”, their brains automatically go to sites such as Twitter or Facebook. |
G.The main idea of Facebook is that you can keep in touch with all your friends around the world who have Facebook. |
2 . Some emerging technologies
Low-carbon cement can help combat climate change.
Concrete, the most widely used human-made material. The manufacture of one of its key components, cement, creates a substantial yet underappreciated amount of human-produced carbon dioxide: up to 8 percent of the global total, according to London-based think tank Chatham House.
In 2018, the Global Cement and Concrete Association announced the industry’s first Sustainability Guidelines, intended to track performance improvements and make them transparent.
Quantum sensors could let autonomous cars “see” around corners.
Quantum computers get all the hype (大肆宣传), but quantum sensors, which reach extreme levels of precision by exploiting the quantum nature of matter, could be equally transformative, enabling autonomous vehicles that can “see” around corners, underwater navigation systems, early-warning systems for volcanic activity and earthquakes, and portable scanners that monitor a person’s brain activity during daily life.
Green hydrogen could fill big gaps in renewable energy.
When hydrogen burns, the only by-product is water—which is why hydrogen has been an alluring zero-carbon energy source for decades. Yet the traditional process for producing hydrogen, in which fossil fuels are exposed to steam, is not even remotely zero-carbon.
Green hydrogen is different. It is produced through electrolysis, in which machines split water into hydrogen and oxygen, with no other by-products. Historically, electrolysis required so much electricity that it made little sense to produce hydrogen that way. The situation is changing since the electrolyzers are getting more efficient.
Whole-Genome synthesis will transform cell engineering.
Early in the COVID-19 pandemic, scientists in China uploaded the virus’s genetic sequence to genetic databases. A Swiss group then synthesized the entire genome and produced the virus from it. Such speed is one example of how whole-genome printing is advancing medicine and other work.
Whole-genome synthesis is an extension of the booming field of synthetic biology. Researchers reprogram microbes to do desired work such as making a new medicine. So far genomes mainly get light edits. But improvements are making it possible to print ever larger number of genetic material and to alter genomes more extensively.

If we can allow our children to be themselves without prejudice, they’ll build friendships with people, regardless of race or religion, who will be by their side through thick and thin. On such friendships are societies built and then we can truly be, as William Shakespeare once wrote, “We happy few. We band of brothers”.

For many, theater is more than entertainment; it is a vital way to build psychological skills-especially empathy, or our ability to share, understand and care about others’ emotions.
Research found that after watching theater, audience expressed more empathy for the characters onstage. The plays also changed behavior. Researchers gave audience members the option to donate some of their payment to charity. After seeing the plays, audience members donated more money to charity-whether or not the charity was related to the topics in the plays.
Why does live theater have these effects? Sitting in the dark watching a play can make us forget our own worries and transport us into the life and mind of a different person. We found that the more people reported feeling “immersed” or “lost” in the play, the more their beliefs and behaviors were changed by it.
A classic finding in social psychology is that repeated, positive encounters with people unlike ourselves can build empathy. Many of us have too few experiences-or too little interest-in creating such encounters. Theaters provide the chance to see the experiences of people who differ from us in environments unlike our own.
The arts are essential to human flourishing(繁荣).As we move beyond the pandemic, we will need to focus on healing collectively and connecting better. Providing greater access to the arts-and using them to share stories across cultural and social difference-will be an important part of this path to recovery.

Liberal Arts’ Hidden Value
If you have to pick one, who do you think made greater contributions to the world: physicist Isaac Newton or philosopher Aristotle?
Chances are that you’d find it hard to make a decision. But when choosing a major in college, the line between the two areas couldn’t be clearer. Science majors, such as technology, engineering, math, are considered to be more practical choices because of the wealth of opportunities, while those who choose a liberal arts (文科) major—language, music, philosophy—may have more difficulty finding a job.
But perhaps we should look at liberal arts studies in another way to understand its value. In the documentary Civilizations, for example, presenters (主持人) take us to 31 countries to appreciate human creativity, such as the Great Wall and the Pyramids. To Simon Schama, one of the presenters, human civilization isn’t just about technology, but about liberal arts or creating things to leave a person’s mark of their existence for future humans to witness and admire.
By comparing science and liberal arts, we’re drawing “an artificial line” between the two, said Loretta Jackson, an associate professor at Rhodes College in Memphis, US. And to some of the greatest innovators (革新者) in history, this line never existed. Leonardo da Vinci, for example, was an outstanding scientist and painter. He was so interested in biology and anatomy (解剖学) that he drew the famous Vitruvian Man, which perfectly shows proportions (比例) of the human body. Then there’s Steve Jobs, who is an engineer and also an artist. He summarized the relationship between science and arts: “It’s in Apple’s DNA that technology alone is not enough—it’s technology married with liberal arts that brings us what makes our heart sing.”

10 . People’s distrust of scientists arises partly from the blurring (模糊的) of boundaries between science and technology, between discovery and manufacture. Most governments, perhaps all governments, justify public expenses on scientific research in terms of the economic benefits the scientific business has brought in the past and will bring in the future. Politicians remind their voters of the splendid machines “our scientists” have invented, the new drugs to relieve old disorders, and the new surgical equipment and techniques by which previously unmanageable conditions may now be treated and lives saved. At the same time, the politicians demand of scientists that they tailor their research to “economics needs”, and that they award a higher priority to research proposals that are “near the market” and can be translated into the greatest return on investment in the shortest time. Dependent, as they are, on politicians for much of their funding, scientists have little choice but to obey. Like the rest of us, they are members of a society that rates the creation of wealth as the greatest possible good. Many have reservations, but keep them to themselves in what they regard as a climate unfavourable to the pursuit of understanding for its own sake and the idea of an inquiring, creative spirit.
In such circumstances no one should be too hard on people who are suspicious of conflicts of interest. When we learn that the distinguished professor assuring us of the safety of a particular product holds a consultancy (顾问工作) with the company making it, we cannot be blamed for wondering whether his fee might cloud his professional judgment. Even if the professor holds no consultancy with any firm, some people may still distrust him because of his association with those who do, or at least wonder about the source of some of his research funding.
This attitude can have damaging effects. It questions the integrity (诚实正直) of individuals working in a profession that prizes intellectual honesty as the supreme virtue, and plays into the hands of those who would like to discredit scientists by representing them as corruptible (腐败的). This makes it easier to dismiss all scientific pronouncements (声明), but especially those made by the scientists who present themselves as “experts”. The scientist most likely to understand the safety of a nuclear reactor, for example, is a nuclear engineer, and a nuclear engineer is most likely to be employed by the nuclear industry. If a nuclear engineer declares that a reactor is unsafe, we believe him, because clearly it is not to his advantage to lie about it. If he tells us it is safe, on the other hand, we distrust him, because he may well be protecting the employer who pays his salary.
