Studies have shown that opportunities are seen to be more valuable as they become less available, according to Robert Cialdini, a leading expert on influence, who said “What the scarcity principle says is that people are more attracted to rare opportunities.”

Appearing available can work against you, according to Jeremy Nicholson, a social psychologist. If you’re excited about a work opportunity, it indicates that you are in low demand.

“Making something harder to get,” Dr. Nicholson said, “tends to increase at least the perception of value.” If you are meeting with hiring managers or potential clients, Dr. Nicholson recommends that responding in a way that respects their interest without being too eager. Dr. Nicholson advises, with responses like: “I do have a couple of other projects to deal with. However, I could do this for you if you want.”

“It’s easy to become excited when an opportunity presents itself,” Ms. Ryan, founder of Human Workplace, said, “but remember that your power in any negotiation is related to your ability to walk away. Don’t accept an offer before fully considering the opportunity.” Once you have interest, turn that into diligence. Ms. Ryan recommends reading up on the organization from third-party perspectives, and checking out job-search websites to see what employees and ex-employees say about it. Keep in mind: The goal is to approach any negotiation cautiously and with a clear head.

Appearing less available isn’t about limiting our enthusiasm, but about trusting in our own self-worth so we can be proactive, experts say. This means mindfully transforming our excitement into strategy. “Emphasizing the uniqueness of your resources and your cooperative approach can help you more quickly advance your goals,” said Shirli Kopelman, a professor at the Ross School of Business at the University of Michigan.

【推荐2】The Art of Man-on-the-Street Interviews

Have you ever observed the busy people of the street? Do they arouse your infinite thinking? The man-on-the-street interview may become a popular word because it is new. The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot.    1    .But with these tips, your first man-on-the-street interview experience can be easy.

When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?”     2    ．

Hit the streets with confidence. As you approach people, be polite. Say, “Excuse me, I work for a certain well-known TV or radio station, and I was wondering if you could share your opinion about this topic.”     3           

    4    ． If someone tells you she is not interested, move on to the next person. Keep in mind that not everyone wants to be interviewed, so don’t get hung up on it.

Limit your time. Each interview that you get on the street shouldn’t be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. A safe number of interviews to conduct is about six to ten.     5    ．

For the media, the ability to increase ratings and influence may be the only meaning they want. In fact, different people have different views towards the interview. Someone says this should be the product of the fast-food information age.

Circling a star about 500 light years away, the planet called Kepler-186f is about the same size as Earth. It goes round its star at the right distance for liquid water on the surface. That is an essential condition for life. But it is not exactly like Earth, it’s more of an Earth’s cousin. It’s not an Earth’s twin. It shares the same characteristics as Earth, but their parent stars are very different.

Kepler-186f circles a star that is smaller and cooler than our sun. But the planet appears to be a closer relative than most of the hundreds of others discovered so far. Some are huge gas-covered giants with thick atmospheres. Others circle too closely to their stars and are too hot for life. For the first time, we can actually say we now have a planet that is both Earth-sized and circles in its star’s livable zone.

The next step would be to look for signs of life in the atmospheres of these distant world. That would take a more advanced telescope. But budget cuts threaten that task, says University of California at Los Angeles astrophysicist (天体物理学家) Ben.

“In theory, we could do this in the next couple of decades. But in practice, because there’s no money, it’s not going to happen. It’s not going to happen in my lifetime, for example,” said Ben. However, NASA’s Elisa Quintana believes that when the next-generation space telescope is used, it will find that we are not alone in the universe. In the meantime, the search continues for other worlds where life may find a home.

“Green snow algae is found in warmer areas along the coastline where summer temperatures are above freezing. but still cold enough for there to be snow.” say scientists in a study published Wednesday in the journal Nature. It’s also more abundant in areas in close proximity to nesting sites and gathering places for animals like penguins and seals, whose feces（粪便）fuel the algae’s growth.

Green algae isn't new for Antarctica—it’s known to have been there to some degree for decades. New Scientist notes. But what researchers found suggests that climate change could have a major impact on algae in Antarctica, which in turn, could have its own impact on a warming planet.

The scientists don't predict that green algae will spread on all part, of the penguin. In fact. some small low-lying islands are likely to lose algae, because those islands may lose their summer snow cover altogether-and the snow algae can't grow without snow. But they predict the amount of green algae is likely to grow on larger pieces of land, where it can spread upward to higher ground that still has snow.

So what does more algae mean, besides turning the landscape green? It’s not totally clear. The green algae works as a carbon sink—the current amount of algae in Antarctica pulls about 500 tons of carbon from the atmosphere each year. On the other hand, algae also makes the surface of the snow darker, which leads to less sunlight being reflected from the snow's surface. Scientific American notes. That means that more of the sun's heat gets absorbed, speeding up wanning. It's high time that we should protect our planet.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if gene technology is applied, not only these two diseases can be cured completely, but also the great amount of money people spend on curing their diseases can be saved, so it benefits the economy as well. In addition, human life-span can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the British royal family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. Scientists just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, so these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in the normal way. Of course, the government must take care to control gene technology.

【推荐1】Imagine this: your child has just been involved in an emergency. You call 911. The medical workers rush in and begin asking you questions as they work to rescue your child. But they also ask questions about your child’s medical history. It’s hard to think clearly. You begin to answer and then end up saying, “I don’t remember. I don’t know.” So many doctors suggest that parents keep handy a record of their children’s important healthy facts. This can often help the medical team make a better and more rapid diagnosis of a problem at a time when time really counts.

The most important information to know is the child’s allergies (过敏). It is especially crucial if the child is allergic to any medicine — penicillin, for example. Food allergies can come into play, so make a note of those as well. Children who have been hospitalized in the past may have developed latex (胶乳) allergies. Often this information can help emergency workers find a cause for problems like breathing difficulties.

Keep a list of any medicine, including what your child is now taking. Some medicines can cause adverse reaction when they are taken together, so the doctors need this information before they give your child anything. You’ll need to know when the child took the medicine last and how much was taken.

It is also important to tell emergency workers about any health problem or illness that your child has had. These pre-existing conditions can have a huge effect on the type of tests and treatment in an emergency. Consider having any child who has a health problem wear a tag around his neck. This kind of rapid notice can help doctors who are providing emergency care, especially if your child suddenly becomes ill at day care, school or a friend’s house.

【推荐2】Traditional Chinese Medicine(TCM) has been greatly contributing to the treatment of the COVID-19, which changed the altitude of the western world to it to some extent. However, in the past, foreigners knew little about it. According to a government report, although TCM has been introduced into 183 countries and regions around the world, their understanding of TCM may be limited to acupuncture(针灸), cupping and massage(按摩) .For instance, the purple, injury-like marks left on a U. S. famous swimmers back from cupping to relax his muscles and reduce pain became the center of attention during the Rio Olympics in 2016.

In fact, Chinese herbs(药草) play a more important role in curing diseases and keeping the body in good condition in the TCM treatment system than physical treatment. Therefore, it is disappointing to know that although 103 world Health Organization member countries have given approval to the practice of acupuncture, not many recognize Chinese herbal medicine. TCM is much less popular than Western medicine partly due to the slow development of Chinese herbs.

Herbs can be made into pills, powder and soup. The kind of herbs used, their quality, quantity and the processing together determine the effectiveness of the prescription (处方). Compared with Western medicine, which has standardized drug production processes and treatment methods, TCM lacks standardization. The chemical composition and functions of its medicine are still unclear and their effects are unstable. Fortunately, standardization has improved in recent decades and a number of factories are increasingly producing patented TCM drugs.

Another reason why TCM prescription drugs have developed slowly is that it lacks creativity. While Western medicine-making companies come up with new products every year, TCM drug producers tend to make medicine according to prescriptions handed down from the past. That Chinese chemist Tu Yoyo won the 2015 Nobel Prize in Physiology or Medicine for her research into malaria(痢疾) treatment may drive creativity to some extent in China's TCM industry.

However, Rome was not built in a day. The current situation cannot be changed within a short time.

【推荐3】There were far fewer cars on the streets and crowds were not seen in the shopping malls in Central China's Wuhan on Jan 24 — the Eve of the Chinese New Year. The scene was quite different from the occasion in the previous years because of the novel coronavirus, which had resulted in 41 deaths in China by the end of New Year's Eve, mostly in Wuhan, according to the National Health Commission.

Chen Li, a doctor in a Wuhan hospital, spent the Chinese Lunar New year's Eve at home to quarantine herself for having had contact with infected patients, but luckily she has no signs of symptoms for the time being. Chen's husband is at the forefront of the fight against the epidemic （流行病）. "We haven’t seen each other for over a week,” said Chen. On Saturday morning, she put on protective clothing again and returned to work.

Wuhan is following Beijing’s SARS treatment model in 2003 to build a makeshift hospital with 1,000 beds for receiving infected patients. It will be completed and put into use prior to Feb 3, less than 10 days away. “It’s going to be another all-nighter. We need to speed up the work,” said Lyu Jun, a young truck driver at the construction site. This is his first Spring Festival away from home.

For ordinary people, this year's Lunar New Year's Eve lacks some gatherings. Yin Yeqiong, from Hunan Province, refunded （退掉）her tickets back home after much debate. “I had it in my mind to still go home, but finally decided to stay in Wuhan,” she said. “Our stay will help reduce panic in other places."

Doctors, nurses and experts from across the nation have been selected to join the battle, and manufacturers have restarted their plants to produce medical consumables that have been running short in many places.

“This is going to be an unforgettable Spring Festival,” said Chen Ying, a writer. ''Because I feel that at this moment, there are so many families that I do not know, in every corner of this city, praying for our home."
