I travel a lot, and I find out different “styles” of directions every time I ask “How can I get to the post office?”

    Foreign tourists are often confused in Japan because most streets there don't have names; in Japan, people use landmarks（地标）in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.”

    In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile.”

    People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. “How far away is the post office?” you ask. “Oh,” they answer, “it's about five minutes from here.” You say, “Yes, but how many miles away is it?” They don't know.

    It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “I don't know.” People in Yucatan believe that “I don't know” is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

    Say you're in the supermarket parking lot，holding your baby，bags of goods，and trying to open your car. A stranger walks up and says，" Here，let me hold your baby." Should you let him?

    According to a new New York University study，knowing whether or not to trust someone is so important that we can tell whether a face is trustworthy before we even consciously know it's there. The researchers knew from previous studies that people are fairly similar when it comes to how they judge a face's trustworthiness. They wanted to find out whether that would be true if people only saw a face for a quick moment—an amount of time so short that it would prevent making a conscious judgment.

    To carry out their study，the researchers monitored the amygdala (扁桃腺结构) of 37 volunteers while showing them 300 faces for 33 milliseconds each. Those faces had already been tested with a different set of 10 subjects，who saw them for much longer. In those earlier tests，people agreed about whether to trust each face. In this new study，fascinatingly，different parts of the amygdala lit up when a subject saw an untrustworthy face and a trustworthy one—and it lit up more when the face in question was suspicious (可疑的).

    " Faces that appear likely to cause harm are suddenly tracked by the amygdala，so it could then quickly change other brain processes and make fast responses to people—approach or avoid，" says Jon Freeman，the study's senior author. "Our talents for making instant judgments could either come from birth or be learned from the social environment."

    So should you trust the guy in the parking lot? Your brain already knows.

Are we alone in the universe? A team of scientists announced on January 6, 2015 that they had identified eight planets beyond our solar system, three or four of which orbit in their stars' "Goldilocks Zone" — the region where temperatures are not too hot or too cold for water, which is a necessary ingredient for life as we know it, to exist liquid form. This may be good news for people hoping that Earth is not the only inhabited world in the universe.

    The scientists, led by Dr. Guilermo Torres of the Harvard-Smithsonian Center for Astrophysics, made the discoveries using data collected by the planet-seeking Kepler telescope.

    NASA launched Kepler in 2009. Since then, the telescope has identified more than 1,000 planets outside of our solar system. Torres and his team analyzed the data about the eight newly discovered world to determine which ones are most likely to be similar to our Earth.

    Among the new discoveries, the scientists say the planets called Kepler438b and 442b are the closest to Earth. Kepler 438b is just about 10% larger than our planet, and gets 40% more of its energy from its star than Earth receives from the Sun. Temperatures there would be about 140 degrees. Kepler 442b is about 33% larger than Earth, but receives 30% less energy from its star. That would make it a potentially chillier world than our own. Torres says it is possible for life to exist and survive in either of those temperatures, but for that to happen, these planets would need to have another key ingredient for life: a heat-trapping atmosphere like Earth's.

    While these findings add to the possibility that life exists beyond Earth, Torres cautions against drawing conclusions, “We are not claiming they are inhabited,” he says. In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unknown whether these planets contain life. But the discovery of planets in their stars' habitable zones suggests that somewhere out there, some form of alien life may have taken hold.

    In the U.S. state of Washington, a road called ^Interstate 90^ cuts through a wild, mountainous area to reach the city of Seattle. For the area's many kinds of animals, the busy highway greatly limits their movements. Crossing 1-90—as the road is called—is a risky but sometimes necessary act. But soon, animals will have a safer choice for crossing the road. They will be able to go above it.

    To help the animals, the state is finishing work on its largest-ever wildlife bridge. The 11-meter-tall, 20-meter-wide structure begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing and plants to help guide the animals across the bridge. Two-meter-thick walls will help block noise from vehicles below.

    The 1-90 Bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges, and some are underpasses. They all aim to keep drivers and animals away from each other. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. In Canada's Banff National Park, studies have found that wildlife crossings reduce the area's animal-driver collisions by 80 percent.

    Most of the wildlife bridges are in western states. But experts have noted many other areas that have a need for such paths. Jen Watkins, whose organization has helped campaign for animal crossings, says finding for more crossings is "the number-one barrier."

    Patty Garvey-Darda of the U.S. Forest Service has worked on the 1-90 crossing from the start of the project. She says the $6- million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. She said, ^"If you shut down Interstate 90, you shut down interstate commerce."

    High school was a hard time for Me in the beginning because I had just moved to a small town and knew basically no one. I loved to play basketball but was afraid to go to tryout (选拔)for the school's team because I didn't know anyone. One day all that changed when I missed the bus home and decided to shoot baskets on the school playground to kill time. The coach Mr Colbath had been watching me make various baskets and was pretty impressed with my moves.

    He came up to me and asked me who had taught me to play like that. I told him that my dad had taught me how to play basketball. He asked me if he would see me at the tryout on Friday, but I said no and told him why. He told me to have a try because I played very well and would maybe make some friends on the court. After thinking for a few minutes. I finally decided to have a try.

    On the day of the tryout, the coach came, found me and helped me practice before the tryout. He helped me a lot and I did very well at the tryout and many members of the team were quite impressed. I did make the team and over the next few years the coach helped me both on and off the court. He helped me do my math which I had such a difficult time with and he even taught me how to live independently.

    I will never forget Mr Colbath. He really inspired me and changed my life. I would not be the person that I am today if he had not taken such an interest in me when I was in high school.

My acquaintance, who never excelled in scholastic pursuits, possessed an innate acuity for aesthetic appreciation. On one occasion, I was engaged in the task of arranging a collection of floral blooms within a container, yet was unable to achieve a visually pleasing arrangement. She approached and, with a few deft motions of her hand, metamorphosed the ensemble into an arresting arrangement of blossoms. Upon receiving commendation for this remarkable proficiency, she dismissed the praise with a nonchalant gesture, perceiving her imaginative prowess as unremarkable.

Frequently, we tend to undervalue our innate competencies, perhaps because we are conditioned to regard only those attributes such as superior intellectual capacity, a proclivity for numerical computation, or an extensive lexicon as possessing intellectual merit. I was graced with the opportunity to discern a different perspective at an early stage of my life.

Upon my commencement of secondary education, a vocational advisor informed my parent that I was not suited for higher education due to my lackluster performance in a spelling component of a standardized assessment. Fortunately, my parent recognized the breadth of my intellectual endowments and advocated on my behalf, demanding that I be included in an academically rigorous curriculum. This episode fundamentally shaped the trajectory of my existence, illustrating the significance of not succumbing to the categorizations imposed by others and enabling me to reach my fullest intellectual capacity.

In the nascent years of the 1980s, Howard Gardner, an eminent scholar from Harvard, introduced the groundbreaking notion of "multiple intelligences." In his seminal work, "Frames of Mind: The Theory of Multiple Intelligences," he posited that intelligence transcends the conventional definition and encompasses a diverse spectrum of cognitive faculties.

What captivates me about the theory of multiple intelligences is its capacity to reconceptualize one's own capabilities and innate skills, particularly those that may not conform to the structured confines of academic paradigms. While it is acknowledged that a threshold of intellectual capability is necessary for success, the analytical competencies gauged by I.Q. assessments do not encompass the complete narrative. Hence, we ought to extol all of our talents and competencies, for they constitute the essence of what renders your individual cognitive capacity so extraordinary and distinctive.
