2 . Imagine a child standing on a diving board four feet high and asking himself the question: “Should I jump?” This is what motivation or the lack of it can do. Motivation and goal setting are the two sides of same coin.     1     Like the child on the diving board, you will stay undecided.

    2     More than that, how should you stay motivated to achieve the goal? First, you need to evaluate yourself, your values, your strengths, your weaknesses, your achievements, your desires, etc. Only then should you set your goals.

You also need to judge the quality and depth of your motivation. This is quite important, because it is directly related to your commitment. There are times when your heart is not in your work.     3     So, slow down and think what you really want to do at that moment. Clarity(清晰) of thoughts can help you move forward.

Another way of setting realistic goals is to analyze your short and long term objectives, keeping in mind your beliefs, values and strengths. Remember that goals are flexible.     4     They also need to be measurable. You must keep these points in mind while setting your goals.

Your personal circumstances are equally important. For example, you may want to be a pilot but can’t become one because your eyesight is not good enough.     5    You should reassess your goals, and motivate yourself to set a fresh goal.

You will surely need to overcome some difficulties, some planned, but most unplanned. You cannot overcome them without ample motivation. Make sure that you plan for these difficulties at the time of setting your goals.

3 . During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.

Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.

Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事) in dangerous and risky behavior.”

In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status                                        has just the opposite effect on us.”

Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date—sharing, kindness, openness—carry over to later years and make you better able to relate and connect with others.

In analyzing his and other research, Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. “Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.

4 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.

On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.

Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”

In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

6 . I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.

I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.

The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH! The parents had done their duty and would probably continue to do so.

8 . Some people say house dust is mostly human skin cells, but it’s only a little bit true.     1    , but there are many other components(成分)on top of your ceiling fans. These include paint, hair, building materials, bacteria, viruses, insect body parts, etc.

That list is based on the Canadian House Dust Study, in which researchers collected dust samples from 1,025 Canadian homes. The proportions(比例)of the components vary from household to household. A house near a busy road, for example, is likely to harbor a high level of outdoor pollutants from car exhaust(废气).     2    .

The commonly-cited statement that 70% to 80% of house dust is human skin cells is likely not true for most houses.     3    , and 40%came from dirt and other materials from outside. That indoor 60%included everything from organic fibers to building materials, not just dead skin cells.

People do drop lots of skin cells as they go about their business.     4    . Not all dead skin flakes(剥落)off onto your home’s floors. Many run down the drain(下水道)in the shower, and others are contained by clothing and end up being washed out in the washing machine.

    5    . One study found that higher levels of cholesterol and squalene (oils found in dead skin) in dust were associated with lower levels of ozone(臭氧)indoors. Ozone is a pollutant that can cause lung discomfort. Ozone reacts with these oils, thus reducing indoor ozone by between 2% and 15%.

9 . Nowadays, the world is slowly becoming a high-tech society and we are now surrounded by technology. Facebook and Twitter are innovative tools; text messaging is still a somewhat existing phenomenon and even e-mail is only a flashing spot on the screen when compared with our long history of snail mail. Now we adopt these tools to the point of essentialness, and only rarely consider how we are more fundamentally affected by them.

Social media, texting and e-mail all make it much easier to communicate, gather and pass information. But they also present some dangers. By removing any real human engagement, they enable us to develop our abnormal self-love without the risk of disapproval or criticism theatrical metaphor (隐喻), these new forms of communication provide a stage on which we create our own characters, hidden behind a fourth wall of tweets, status updates and texts. This unreal state of unconcern can become addictive as we separate ourselves a safe distance from the cruelty of our fleshly lives, where we are imperfect, powerless and insignificant. In essence, we have been provided not only the means to be more free, but also to become new, to create and protect a more perfect self to the world. As we become more reliant on these tools, they become more a part of our daily routine and so we become more restricted in this fantasy.

So it is that we live in a cold era, where names and faces represent two different levels of closeness, where working relationships occur only through the magic of email and where love can start or end by text message. An environment such as this reduces interpersonal relationships to mere digital exchanges.

Would a celebrity have been so daring to do something dishonorable if he had had to do it in person? Doubtful. It seems he might have been lost in a fantasy world that ultimately convinced himself into believing the digital self could obey different rules and regulations, as if he could continually push the limits of what’s acceptable without facing the consequences of “real life.”

10 . If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?

According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter density (灰质密度). This is the area of the brain which processes (加工) information. It is similar to the way that exercise builds muscles. The study also found the younger people learn a second language, the greater the effect is.

A team led by Dr. Andrea Mechelli, from University College London (UCL), took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.

Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was.

“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists. It means that the change itself increases the ability to learn.

Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible.” he said. “You are actually going beyond language and have a better understanding of different ideas.”

The findings were matched in a study of native Italian speakers who had learnt English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.
