1 . New efforts are being made to prevent American college campuses from cigarette smoking. Twenty colleges in the United States recently received money to help protect their campuses from the harm of cigarettes.
Supporters say that every child deserves to grow up in a safe and healthy environment free from harmful second-hand cigarettes. And in November, smoking at college campuses may become illegal.
Before banning smoking at college campuses, the US has passed laws banning smoking at most workplaces. 27 American states ban smoking in all indoor workplaces.
Those supporting smoke-free at workplaces and college campuses give one major reason: the bad influence of smoking on health.
The Centers for Disease Control (CDC) says smoking has a great influence on health. They think cigarette smoking is the leading cause of preventable deaths in the United States. Smoking is responsible for 480,000 deaths every year.
Supporters say the bad influence of second-hand smoke makes it a public health problem. Some also say that college campuses are a good place to ban smoking.
Gary Reedy, the CEO of the American Cancer Society, said it was important to stop college students from smoking, and he expected to successfully create a cigarette-free generation (世代).
The CDC found that 13 percent of adults between the ages of 18 and 24 smoke cigarettes. Reedy says that reducing the number of college students who smoke can help reduce the number of older adult smokers. He also says once a person starts smoking, it is hard to stop.

2 . How similar are language and music?
Language is part of our daily lives, no matter where we live in the world.
Both language and music have a writing system.
In English we record language using the alphabet, which is a collection of letters. Similarly, we use notes (音符) to keep a record of music. Musicians read notes and create meaning in the form of music.
You can make a good guess at where someone is from by listening to the language he uses. In the same way, we know that styles of music are different around the world, giving us the opportunity to explore many different cultures through their music and providing us with music for every situation.
Both share emotion.
| A．Both are expressive. |
| B．Both vary with culture. |
| C．How do you know that I am angry? |
| D．We use language to express our thoughts. |
| E．Similarly, music is part of many people’s lives. |
| F．So just as you read English, you can read music. |
| G．In contrast, you probably also listen to sad music when you are feeling down. |
3 . With almost all big employers in the United States now using artificial intelligence (AI) and automation in their hiring processes, the public is considering some urgent questions: How can you prevent discrimination in hiring when a machine is keeping the discrimination? What kind of methods might help?
Some 83% of employers, including 99% of Fortune 500 companies, now use some form of automated tools as part of their hiring process, said the Equal Employment Opportunity Commission’s (EEOC) chair Charlotte Burrows at a hearing on Tuesday. She said everyone needs to speak up on the debate over these technologies. “The risks are simply too high to leave this topic just to the experts. ”
Last year, the EEOC issued some guidance around the use of cutting-edge hiring tools, noting many of their shortcomings. The agency found that resume (简历) scanners that prioritize keywords and programs that evaluate a candidate’s facial expressions and speech patterns in video interviews can create discrimination. Take, for example, ‘a video interview that analyzes an applicant’s speech patterns to determine their ability to solve problems. A person with a speech problem might score low and automatically be screened out. The problem will be for the EEOC to root out discrimination-or stop it from taking place.
The EEOC is considering the most appropriate ways to handle the problem. It’s agreed that inspections are necessary to ensure that the software used by companies avoids intentional or unintentional discrimination. But who would conduct those inspections is a more challenging question. Each option presents risks, Burrows pointed out. A third party may turn a blind eye to its clients, while a government-led inspection could potentially stop innovation.
In previous remarks, Burrows has noted the great potential that AI decision-making tools have to improve the lives of Americans, but only when used properly. “We must work to ensure that these new technologies do not become a high-tech pathway to discrimination,” she said.

5 . There is a popular saying in the English language: “Sticks and stones may break my bones, but words will never hurt me.” Well, that is not true. Unkind words, name-calling or even the so-called “the silent treatment” can hurt children as much as being physically hit, sometimes even more so. A recent study of middle school children showed that verbal (言语的) abuse by other children can harm, the development in the brain. The study was a project of researchers at Harvard Medical School in Massachusetts. Researcher Martin Teicher and his team studied young adults, aged 18 to 25. These young men and women had not ever been treated in a cruel or violent way by their parents. The researchers asked the young people to rate their childhood exposure to verbal abuse from both parents and other children. Then the researchers performed imaging tests on the brains of the subjects.
The images showed that the people who reported suffering verbal abuse from peers in middle school had underdeveloped connections between the left and right side of the brain. The two sides of the brain are connected by a large bundle of connecting fibers called the corpus callosum. This was the area that was underdeveloped.
The middle school years are a time when these brain connections are developing. So, unkind, hurtful comments from children or adults during this period have the greatest effect. The researchers tested the mental and emotional condition of all the young people in the study. The tests showed that this same group of people had higher levels of fear, depression, anger and drug abuse than others in the study.
The researchers published their findings online on the American Journal of Psychiatry's website.
Parents cannot control what other people say to their children, but they can prepare their children.

6 . Surfing the Internet for fun will make you a better employee, according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive (有效率的) than those who do not. Study author Brent Coker said “Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,” Coker said on the university’s website.” Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day’s work, and as a result, increase productivity (生产效率),” he said.
According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.” Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online,” said Coker. “That’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.

7 . From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a potential threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.
“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.
A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.
The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.
But the report states: “Losing occupations does not necessarily mean losing jobs — just changing what people do.” Growth in new jobs could occur as much, according to the research.
“The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies,” it states.
A report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report's co-author.
“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft's Jonathan Grudin told researchers.

8 . 4 Popular Places to Go This Winter
Harbin, China
China Harbin’s winter is for the brave ones—the average temperature is 1.8°F- but those who brave the cold will be rewarded with experiencing one of the world’s largest winter festivals. 2021 marks the 37th Harbin International Ice and Snow Sculpture Festival (January-March), when massive frozen structures rise and are lit up, transforming the city into a winter wonderland.
Lyon, France
Paris may be called The City of Light,but every December, light takes center stage in Lyon, France’s third-largest city. That’s when the annual Festival of Lights (around December 8) takes over, with light installations (装置)that transform the city’s streetscapes into modern works of art. The city is also home to two Christmas markets (one in La Croix-Rousse; the other at the Place Carnot; through December 25).
Lima, Peru
Peru’s capital Lima is home to the world’s highest number of cooking schools per person. Aside from its delicate dining, the city also has great cocktail bars where you can taste classic or contemporary takes on the Pisco Sour.Combine that with the oceanfront setting and temperatures in the 80s, and you’ll understand why Lima should no longer be ignored this winter.

9 . Barbara McClintock was one of the most important scientists of the 20th century. She made important discoveries about genes and chromosomes(染色体).
Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to the Brooklyn area of New York City in 1908. Barbara was an active child with interests in sports and music. She also developed an interest in science.
She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.
Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed the master’s degree in 1925. Two years later, she finished all her requirements for the doctorate degree.
McClintock stayed at Cornell after she completed her education. She taught students botany. The 1930s was not a good time to be a young scientist in the United States. The country was in the middle of the great economic depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.
An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started a temporary job with the genetics department. A short time later, she accepted a perpetual position in the laboratory and got continual incomes. This gave her the freedom to continue her research without repeatedly asking for financial aid.
By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.
