Most science-based shortcuts to happiness- like working out, smiling more and practicing gratitude -focus on the positive, and they’re helpful indeed. But in a study, researchers surveyed more than 2,300 college-age students in eight countries, including the U.S, Brazil and China. Students were asked which emotions they wanted to feel more and less in daily life- -like love, anger and excitement- -and which ones they actually felt. They also answered questions that measured for depressive symptoms and overall wellbeing.
Many students said they wanted to feel more pleasant emotions, like love and empathy, than they felt on a regular basis. However, 11 percent wanted to feel fewer pleasant emotions, and 10 percent wanted to feel more unpleasant emotions, like anger and hatred. Overall, study participants who actually felt the emotions they desired reported greater life satisfaction and fewer depressive symptoms. It turned out that for some people, embracing negative feelings may be one of the most powerful ways to feel happier overall.
It likely all comes down to which emotions you value as a person, according to Maya Tamir, a psychology professor. “For example, someone who feels no anger when reading about child abuse might think she should be angrier about the plight of abused children, so she wants比feel more anger than she actually does in that moment. A woman who wants to leave an abusive partner but isn't willing to do so may be happier if she loves him less."
Of course, the same emotions aren't “right" for everyone, and the reason they feel right depends on a person's social, cultural and personal values. Take anger for example.
“For a minority group member who seeks justice because people in the majority mistreat him, feeling anger may just be the right emotion," the study authors wrote. “Whether an emotion is right, therefore, depends on the goals and needs of each individual. Whereas anger may feel right to some, it may feel wrong to others."
“Wanting to be happy or joyful all the time is not very realistic," Tamir said. "Never wanting to feel sadness or anger or fear is not realistic. If we are able to accept and even welcome the emotions that we have, whether they are pleasant or unpleasant, we are likely to be happier and more satisfied."
The study only analyzed one class of negative emotions, called negative self-enhancing emotions, which include hatred, hostility, anger and contempt. The authors suggested future research should be conducted on other negative feelings like fear, guilt and sadness.
Next time you want a happiness boost, try listening to a sad song or having a good cry. Science knows it may be just what you need.
58. What is proved in the new study?
A. There is no scientific evidence for shortcuts to happiness.
B. Negative emotions are key to happiness for some people.
C. People feel more pleasant emotions in their daily life.
D. Life satisfaction results from the positive feelings.
59. According to the text, the emotions you feel reflect____________
A. how you feel at that very moment
B. whether you consider it helpful
C. what you value to be a person
D. if there are fewer depressive systems
60. How does Tamir think you can be happier?
A. Be realistic in our individual needs.
B. Try to be joyful even in negative situations.
C. Accept the existence of right emotions.
D.Experience the emotions we have.
Michael Atiyah, a mathematician at the University of Edinburgh, announced at the Heidelberg Laureate Forum in Germany that he had come up with a simple proof to solve the Riemann Hypothesis.
The hypothesis was first put forth by German mathematician Bernhard Riemann in 1859. Prime numbers(质数), or those whose only factors(因数) are 1 and itself- such as 2, 3, 5 and 7- don't seem to follow a regular pattern on the number line.
However, Riemann saw that the frequency of prime numbers apparently closely follows one equation(方程式) that became known as the Riemann zeta function, according to the Clay Mathematics Institute. If the equation holds true, it would describe the distribution of prime numbers all the way to infinity.
But as of now, it has been checked for only the first 10,0000,000 solutions, according to the institute, and the problem remains “unsolved". The person who solves the Riemann zeta function, or one of the other six big mysteries in math that make up the“Millennium Prize Problems" will win an award of$1 million from the institute.
Atiyah's proof is based on an unrelated physics number called the “fine structure constant", which describes the electromagnetic( 电磁的) interactions between charged particles, according to Science. He describes this constant using another equation called the Todd Function, to prove the Riemann Hypothesis by contradiction, according to Science. In math, contradiction is one type of proof in which you assume that the “thing”you want to prove is untrue and then show how the results of this assumption are just not possible.
Atiyah has made major contributions to math, winning top mathematics awards- the Fields Medal in1966 and the Abel Prize in 2004. But in recent years he has also put forth some mathematical proofs that didn't hold up- and now many of his colleagues are critical of his new claims and say they're unlikely to hold true, according to Science.
“The proof just stacks(堆叠) one impressive claim on top of another without any connecting argument or real proof," John Baez, a mathematical physicist at the University of California, Riverside, told Science.
In his talk, Atiyah described many, many times people have claimed to have proved the hypothesis, only to be proven wrong. "Nobody believes any proof of the Riemann Hypothesis because it's so difficult, nobody has proved it, and so why should anybody prove it now? Unless, of course, you have a totally new idea," he said.
61. Michael Atiyah claimed to have discovered
A. the Riemann Hypothesis
B. the factors of prime numbers
C. the equation mentioned by Riemann
D. the truth of the Riemann zeta function
62. What can we know from the text?
A. Michael Atiyah has great achievement in the field of physics.
B. According to Science, Michael Atiyah's proof is based on physics.
C. The Clay Mathematics Institute was started by Bernhard Riemann.
D. The Riemann zeta function is one of the six big mysteries in math.
63. Which of the following can be used to describe “contradiction" in math?
A. If A is the result of B and A is true, then B is true.
B. If A is the result of B and A is false, then B is false.
C. If A is contrary to B and A is false, then B is true.
D. If A is true and B is false, then A is contrary to B.
64. What did John Baez think of Michael Atiyah's proof?
A. It's not satisfying.
B. I's obviously wrong.
C. It's too difficult to understand.
D. It's given some new ideas to him.
In this special issue focused on the leading edge of scientific research into all the things about muscle, one, key fact stuck out as I read through the interesting stories it contains. One of this issue's feature articles, How Muscles Age, and How Exercise Can Slow It, begins with researchers Gillian Butler-Browne, Vincent Mouly, Anne Bigot, and Capucine Trollet writing, “To you readers over age 30, we've got some bad news for you. Chances are good you've already begun losing muscle."
This is a reality that my 40*-year. old body registered long before I read that passage. Nonetheless, seeing it spelled out in front of my face drove the discouraging point all the way to the depths of my withering sarcomeres(菱缩的肌节). Butler-Browne and her coauthors do give us a ray of hope, detailing exercise's ability to stop or reverse this trend, even in people older than 70.
This gradual wearing down of physiology brings to mind another alarming trend happening in our world. Some people have been stepping up their disturbing attacks on the media, often repeating the phrase: "The press is the enemy of the American people."
I won't spend too much ink here because my colleagues at The Boston Globe, the Honolulu Star-Advertiser, Anchorage Daily News, and other outlets have done a good job in this regard.
I can, however, share insights from the perspective of a science journalist. In our business, we're no . strangers to the post-publication protest that sometimes breaks out among researchers, industrialists, and members of the public. After all, one person's well-supported scientific fact can be another's headache. Exposing the dangers of widely sold chemicals, highlighting the damage caused by climate change, or correcting mistaken public views about vaccines is all in a day's work for a science journalist.
And just like those who make a live report, science journalists must often relate facts about the people and institutions they cover. For decades, The Scientist has been one of the clearest voices calling out instances of misconduct, waste, shoddy(劣质的) research, and hype(天花乱坠的报道) in the scientific community. Far from being an antagonist of science or researchers, science formalists reporting, writing, and editing such stories seek to promote the pursuit of knowledge by holding those at the helm(舵) accountable and keeping them honest. Transparency and accountability make the scientific enterprise stronger, and create a safer environment, and more informed citizenry protected by sound policy. As journalists covering science, it is not only our duty to shine a light on discoveries and help inform the public, but also to bring scientific facts to bear on hot issues, and to expose the darker corners of the scientific enterprise so that the many can learn from the mistakes of the few.
These precepts(准则) of responsible journalism, like aging muscle, can atrophy(萎缩) if not exercised. And this withering can be sped up when people actively seek to undermine(暗中破坏) our efforts.
As you read this issue, which includes a large number of interesting muscle facts and one or two well-founded muscle opinions, know that we at The Scientist pledge(保证) to continue to fulfill our journalistic duty with strength and clarity, as we have for more than three decades.
65. The author's purpose in mentioning the feature article about muscle is, ____________
A. to compare it with the shoddy research in the scientific field
B. to stress the necessity of following precepts of journalism
C. to tell readers the benefit of reading scientific journals
D. to show the importance of doing scientific research
66. How did the author feel when he read the article mentioned in Paragraph 1?
A. Uninterested. B. Surprised. C. Curious. D. Upset.
67. What's the author's attitude towards his colleagues' reaction to the attack on the media?
A. Favourable. B. Indifferent. C. Doubtful. D. Unsatisfied.
68. Why are post-publication protests common for journalists?
A. Because scientific journals may focus on society's dark corners.
B. Because there are too many hypes in the scientific community.
C. Because the reports may threaten some people's interests.
D. Because many people believe the media are their enemies.
69. The underlined word “antagonist' in Paragraph 6 is closest in meaning to“_____”
A. recorder B. enemy C. competitor D. gossip
70. What does the author believe is the most important to the success of The Scientist?
A. How it chooses interesting articles.
B. The style it employs to cover events.
C. Its responsibility and accountability.
D. Prevention of efforts being undermined.
Beliefs are our brain's way of making sense of our complex world. They are mental representations of the ways our brain expects things in our environment to behave, and how things should be related to each other- the patterns our brain expects the world to conform to. Beliefs are models for efficient learning and are often key to one's survival.
The brain is an energy- expensive organ, so it has to evolve energy- conserving efficiencies. As a prediction machine it must take shortcuts for pattern recognition, as it processes the vast amounts of information received from the environment by its sense organ outgrowths. Beliefs allow the brain to distill complex information, enabling it to quickly classify and evaluate information and to jump to conclusions.
In its need for economy and efficiency of energy consumption, the tendency of the brain is to fit new information into its existing framework for understanding the world, rather than repeatedly reconstruct that framework from scratch.
It seems likely that the processes in the brain involved in abstract belief formation evolves from simpler processes involved in interpreting sensory perception.
Since we experience the world entirely through our senses, we find it hard to accept that these opinions are sometimes subjectively misrepresented and that they are not necessarily reliable experiences of objective reality. People tend to trust their physical senses and to believe their opinions no matter how strange their perceptual distortions are. People will layer explanations on top of their perception of reality to explain away contradictions.
We give our subjective experience too much trust, and so too our beliefs. We will more readily explain away evidence that contradicts our cherished belief by expanding and describing that belief with additional layers of distorted explanation, rather than abandoning it or fundamentally restructuring it.
Science values the changing of minds through disproving previously held beliefs and challenging received authority with new evidence. Science requires training. It is a disciplined method that tries to systematically overcome or bypass our intuitions and cognitive biases and follow the evidence regardless of our prior beliefs, expectations or preferences.
The increasing application of the scientific method in the last four centuries has promoted unprecedented progress in humanity's quest to understand the nature of reality and made vast improvements in quality of life. Discovering just how mistaken we collectively were about so many things has been the key to sensational

China has historically placed a high value on children’s education. Due to the country’s vast population and the limited resources of elite(出类拔萃的)schools, not only is there fierce competition in entrance exams, but there are also top colleges putting students’ unique abilities—such as performances in science competitions, writing abilities, oral skills, musical talents, and achievements in dance—under the microscope(显微镜). The cruel competition has been blamed by those who feel that it occupies children’s free time and places too much stress on performance under test conditions. Against this background, many primary and secondary schools in China have begun to promote the so-called “happy education”, trying to reduce students’ burden in school. However, in these schools, there exists an obvious paradox(自相矛盾). On the one hand, the official education system is attempting to reduce the burden of schoolwork on students. On the other hand, more and more time students spend outside the classroom is being devoted to educational training organizations. Many students are almost taking part in every kind of competition, from nationwide tournaments like the International Mathematical Olympiad to all manner of local competitions. So is this “happy education” practical or just failing the students?

To reduce students’ burden, many Chinese primary and secondary schools have been promoting “happy education”. However, whether it’s practical remains to be seen and doubted.
As far as I’m concerned, receiving an education, especially a further one, isn’t always an enjoyable process. And education won’t work effectively unless students themselves are eager for knowledge and love studying. Therefore, it’s wise for schools to consider the “happy education” seriously.
As for me, I’d love to take the main subjects in school and study what I’m interested in outside school. In order to keep a balance, I make every minute in school worthwhile by reading my textbooks in advance and listening to the teachers attentively. When I can ensure my academic performance in school, I will enjoy learning what I love after school, which will help me become what I want to be in the future.
