Choose What to Remember, What to Forget
I was sorting through some boxes in the drawer last week when I came across a teddy bear from my childhood.
First, volunteers were shown how to create connections between an item and negative emotions. They did this using vivid mental imagery (意象) — linking a child’s sports shoes to images of a playground accident, for example, so that the object became uncomfortable to have nearby.
The pictures you attach to things can connect you to some extremely powerful memories, for good or bad.
A.Unpleasant past memories flashed through my mind. |
B.It shows that recall relies on associations and images. |
C.Not all objects make such welcome memories, however. |
D.Powerful memories flooded back from nearly 50 years before. |
E.But the good news is that you can choose to remember the good things. |
F.Again, strengthening the images will continually sharpen the memories. |
G.Later, they were shown how to actively forget those feelings by pushing away any pictures. |

What is a “good friend”? How is he best described? Well, it has been my observation that although many will cry with you, few can sincerely rejoice (欣喜) with you. Therefore, in my opinion, a good friend is one who can enjoy your successes without envy; one who can say, “That was wonderful! You can do it again, even better if you want!” and mean it. Nothing taxes a friendship more than the success of one and not the other. Even the closest of friendships often cannot resist such pressure and fail. No wonder many minor friendships go down day by day for the same reason.
A person of good character and sound moral, of honor and humor, of courage and belief is a friend to be sought and treasured — for there are few. Too often we hear, “If you can count your good friends on more than one hand, consider yourself blessed.” And even then I would add, “Even if you have lost two fingers of that hand to the electric saw.
What makes a friendship last? Well, I don’t know all the answers, but one of my observations is that most good friends usually have similar tastes. They generally like and dislike many of the same things. There also usually seems to exist a similarity of personality types — especially in the fundamental values of life such as honesty, sincerity, loyalty, and dependability. More often than not, birds of a feather do fly together. I don’t think it matters a lot whether one prefers jazz or hockey to another’s Mozart or ballet. Much other matters far more: relying, sharing, giving, getting, enjoying; a sympathetic ear always there; criticism when it can help; praise — even if only because it would help. With not many people on this earth will you find this much in common. When you find one, hang on to him, for a good friend found is a rare treasure.

【推荐2】A life lesson is just what it sounds like — a lesson we learn in life. It’s really based on the idea of learning from our mistakes. These lessons could be described as defining (决定性) moments that are remembered.
Life lessons can occur in any area. Although we learn many things each day, we don’t always learn something that we feel will affect our behavior for the rest of our lives.
An example of a life lesson in the area of work and career could be the revelation that making a modest living at something we are passionate about is better than working at an unpleasant or dull job for more money.
A.If so, follow your heart. |
B.They are based on an individual’s life experiences. |
C.Life lessons can help us understand ourselves better. |
D.This separates a life lesson from everything else we learn. |
E.Are you more motivated and inspired to pursue your dreams? |
F.Such lessons in relationships are as varied and unique as each relationship. |
G.To put it simply, a life lesson teaches us not to make the same mistake twice. |
【推荐3】Shyness is the cause of much unhappiness for a great many people. Shy people are easily embarrassed and nervous. They are extremely concerned about their own appearance and actions. Worrying thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?
It is obvious that such uncomfortable feelings can negatively affect people. A person’s view of himself or herself is shown in the way he or she behaves, and the way a person behaves affects other people’s reactions. In general, the way people think about themselves has a great effect on all areas of their lives.
Shy people who don’t like themselves and don’t think that they are valuable are likely to be passive and easily influenced by others. They need someone to help them stop worrying and tell them that they are doing “the right thing.” Shy people are very sensitive to criticism; they feel it shows that they are not good. They also feel uncomfortable when they receive praise. So they usually reply by saying, “You’re just saying that to make me feel good. I know it’s not true.”
Can shyness be completely removed, or at least reduced? Fortunately, people can overcome shyness with determined and patient efforts by building their self-confidence. Since shyness goes hand in hand with a lack of self-esteem (自尊), it is important for people to accept their weaknesses as well as their strengths.
Each one of us is a unique individual and has our own personal ways. The better we understand ourselves, the easier it becomes to live up to our full potential (潜能). Let’s not allow shyness to prevent us from having a rich and satisfying life.

【推荐1】For reasons that are deeply rooted in culture and tradition, men significantly outnumber (比... 多)women in mathematics-based careers. As students progress through the mathematics courses, girls and boys show little difference in ability, effort, or interest in mathematics until adolescent years when course and career choices begin influencing school effort. Then, as social pressure increases and career goals are formed, girls' decisions to reduce effort in the study of mathematics progressively cut them off from many professional careers in the future.
Many girls drop mathematics in high school or in the transition to college. Others drop out later. Women perform virtually as well as men in college mathematics courses, but beyond the bachelor’s degree women drop out of mathematics at twice the rate of men. Women now enter college nearly as well prepared in mathematics as men, and 46 percent of mathematics baccalaureates (学士学位)go to women. Despite this record, only 35 percent of the master's degrees and 17 percent of the Ph. D degrees in the mathematical sciences are earned by women.
Overall, women receive approximately one third of university degrees in science and engineering. The highest percentages of women are found in those sciences with the least mathematical prerequisite: psychology, biology, and sociology. The lowest percentages of women enter fields requiring the most mathematics, namely, physics, engineering, economics, geo- science ,and chemistry. Evidence from many sources suggest that it is differences in course patterns rather than lack of ability that matter most in limiting women's access to careers in mathematically intensive sciences.
Widely reported studies concerning the high percentage of boys among mathematical prodigies (天才)---those who at age 12 perform at the level of average college students-often convey the impression that gender differences in mathematics are biologically determined. But evidence from the vast majority of students shows almost no difference in performance among male and female students who have taken equal advantage of similar opportunities to study mathematics. Inferences from very exceptional students——child prodigies—mean little about the performance of the general population.

【推荐2】The cultivation of plants by ants is more widespread than previously realized, and has evolved on at least 15 separate occasions.
There are more than 200 species of ant in the Americas that farm fungi (真菌) for food, but this trait evolved just once sometime between 45 million and 65 million years ago. Biologists regard the cultivation of fungi by ants as true agriculture appearing earlier than human agriculture because it meets four criteria: the ants plant the fungus, care for it, harvest it and depend on it for food.
By contrast, while thousands of ant species are known to have a wide variety of interdependent relationships with plants, none were regarded as true agriculture. But in 2016, Guillaume Chomicki and Susanne Renner at the University of Munich, Germany, discovered that an ant in Fungi cultivates several plants in a way that meets the four criteria for true agriculture.
The ants collect the seeds of the plants and place them in cracks in the bark of trees. As the plants grow, they form hollow structures called domain that the ants nest in. The ants defecate (排便) at designated absorptive places in these domain, providing nutrients for the plant. In return, as well as shelter, the plant provides food in the form of fruit juice.
This discovery prompted Chomicki and others to review the literature on ant-plant relationships to see if there are other examples of plant cultivation that have been overlooked. “They have never really been looked at in the framework of agriculture,” says Chomicki, who is now at the University of Sheffield in the UK. “It’s definitely widespread.”
The team identified 37 examples of tree-living ants that cultivate plants that grow on trees, known as epiphytes (附生植物). By looking at the family trees of the ant species, the team was able to determine on how many occasions plant cultivation evolved and roughly when. Fifteen is a conservative estimate, says Campbell. All the systems evolved relatively recently, around 1million to 3 million years ago, she says.
Whether the 37 examples of plant cultivation identified by the team count as true agriculture depends on the definitions used. Not all of the species get food from the plants, but they do rely on them for shelter, which is crucial for ants living in trees, says Campbell. So the team thinks the definition of true agriculture should include shelter as well as food.

【推荐3】What exactly is a lie? Is it anything we say which we know is untrue?
Professor Jerald Jellison of the University of Southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks terrible.
Another gesture which gives liars away is what the writer Desmond Morris in his book Man Watching calls “the mouth cover”. He says there are several typical forms, such as covering part of the mouth with fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth.
A.However, this is only one side of the story. |
B.Or is it something worse than what it really is? |
C.A “white lie” appears to be a lie that the teller tells to profit or gain some advantage from it. |
D.The tip of the nose is very sensitive to such changes and the increased pressure makes it itch (痒). |
E.Why people sometimes cover their mouths while lying is that they wish those words had not come out of their mouths. |
F.Such a gesture can be understood as an unconscious attempt on the part of the liar to stop himself or herself from lying. |
G.Research has also studied the way people’s behavior changes in a number of small, apparently unimportant ways when they lie. |
