The ability to speak more than one language certainly has its special benefits.It enables you to work in another country or interact with people whose language is different from your mother tongue.Cognitive（认知的）  psychologists have been interested in how bilingualism（双语能力）shapes the mind for almost a century.There are those who suggest that in order to speak one language,bilinguals have to suppress（抑制）the influence of the other.In the past three decades,research had argued that this unique form of language processing trains the brain in the use of abilities known as "executive（执行的）functions" such as ignoring irrelevant information or shifting attention. Bilinguals of different ages and cultural backgrounds have been shown to be faster and more accurate than their monolingual（单语的）peers when performing cognitive tasks demanding these abilities.Furthermore,it has been argued that bilingualism may lead to a delayed onset（发作）of symptoms associated with dementia（痴呆）.

    But the scientific community recently has become increasingly skeptical of the bilingual advantage.One of the main points of criticism is that differences between monolinguals and bilinguals when it comes to executive functions are not always apparent.It appears that research on bilingualism is at a turning point.We need to pursue a new approach to understand,beyond those individual examples of executive functions,how the bilingual mind works. We have attempted to address this challenge by testing whether bilinguals and monolinguals differ in terms of how accurately they can assess their own performances.This ability is called meta cognition and is associated with other areas where bilinguals have been shown to have an advantage.

    In our research,we presented participants with a situation in which they had to observe two circles on a screen and guess which one contained more dots.Sometimes the difference was obvious,making the decision easy,while at other times the decision was very difficult (for example,one circle contained 50 dots and the other 49).Participants were then asked to determine how confident they were in their decision on a scale from less to more confident than normal.

    During the course of two experiments,we found that bilinguals and monolinguals were equally likely to choose the circle containing the highest number of dots.However,monolinguals were better able than bilinguals to discriminate between when they were right and when they were wrong.In other words,bilinguals had less insight into their performance than monolinguals.This went against our initial predictions,as we expected to find a bilingual advantage in meta cognitive processing.These results indicate that bilingualism may be associated with cognitive disadvantages as well as benefits.

    Imagine yourself on the other side of the college admissions desk. It's not so glorious, apparently. At the very least, you need to be good-natured. Joseph Connolly, a guidance counselor at New Oxford High School in the United States, wanted to know the things that annoy admissions officers the most. He sent out a request to members of the National Association for College Admissions Counselors and received hundreds of responses. Apparently, college admissions officers were waiting for an opportunity to unload their frustrations. The responses fall into several areas:

    Communication

    Silly or stupid email addresses; sending emails that use texting shorthand, such as "im w8ing 4 some1 2 call me."

    Leaving a message with just a first name and no telephone number. For example, "Hi, this is Suzie. Please call me back."

    Acting distracted during a one-on-one interview; nervous habits like foot-tapping or "um", "like" and "you know", which make a bad situation worse.

    Not responding to emails from the admissions office.

    Over-involved parents

    The very common comment from parents, "We are in the process of completing applications."

    Parents attending interviews, and worse yet, speaking for their children.

    Essays

    Not identifying which question they are responding to.

    Writing about something they were great at in the seventh grade but haven't pursued since then.

    I'm big into reading, and since you're on this page, I guess you like reading as well. This page is an ongoing log of books I find to be awesome or useful. If you're looking to create a well-rounded, successful college experience, you can't go wrong with any of these.

    The Power of Habit

    This book is absolutely amazing. As it turns out, habits shape much more of our behavior than we realize. The habits we do have largely determine the progress (either good or bad) we make in life. Luckily, the way habits are formed can be understood—which means they can be changed—and The Power of Habit is the best overview of how habits work that I've ever read.

    A Mind for Numbers

    If you're looking for practical techniques you can use to increase your ability to learn new information effectively, you should read this book. Contrary to what the title would imply, Dr. Barbara Oakley's A Mind for Numbers is applicable to any learning discipline--not just math and science. This book will quickly give you an understanding of how your brain learns and encodes (编码) new information, and will also equip you with strategies for learning more while studying less.

    Brain Rules

    If you know how the brain works, you'll be better equipped to manage your own and understand the ones contained inside the heads of the people you know and meet In Brain Rules, John Medina expertly shows us how the brain does things, and lays out 12 rules that form a basis for using that pile of mush (糊状物) more effectively. It's not just an excellent brain book—it's an excellent business book and an excellent college success book as well.

    Spark: The Revolutionary New Science of Exercise and the Brain

    I firmly believe that a solid foundation of nutrition, exercise, and sleep will help you succeed in college better than any study hack, which is why I recommend this book. Reading it will educate you on how exercise affects your brain, which in turn will give you more mental ammunition (弹药) that you can use to shoot down excuses when you're feeling lazy or “busy”, and don't want to work out. By the way, how much exercise have you gotten today?

    Have you ever complained, "I remember reading it, but I can't remember what it said? " then you should try the SQ4R reading method.

    S = Survey. The first step is to take a few minutes skimming the chapter. Don't read it yet, just look at topic headings, key words, and read the summary.

    Q = Question. As you prepare to read the chapter, turn the first topic into a question or two. As you read, seach for the answer. This will help you organize your reading-find the parts that answer your question, give an example, consist of related information or that may answer a later question. Most importantly, this gives you a reason to read the next paragraph.

    R = Read. Read in short "bites" (部分), then determine how that answers question(s) you originally posed (提出). Often as you read other questions will arise.

    R = Recite. Now can you answer your question(s) in your own words? If you can't, reread the material to find the answers or determine if you need to change the question. You are rehearsing (重复，默诵) for the time when you will need o know the answer. A good technique for rehearsing answers is to briefly jot down (草草记下) the key words that remind you of the essence of the answer without writing down every detail.

    R = Relate. Most of us try to relate what we are reading to what we already know. It is always easier and more satisfying to remember information that is personally meaningful. Everything has a context. Some information may take more reflection before you are able to grasp its relationship with what you already know while other information may simply require more research, to understand how it fits with other data.

    R = Review. One way to minimize memory decay (衰退) and to store the material you have studied firmly in your mind is by reviewing it. After you finish reading the entire chapter, skim back over it and any note you made.

    Effective studying requires effective reading. Rather than getting "intellectual indigestion" while reading straight through a chapter, instead you should stop to survey, question, read, recite, relate, and review so as to improve your reading comprehension.

    Annette Larkins is an incredible woman who looks like a healthy 40-year-old, although she just turned 70. She follows a special raw diet and only drinks rainwater.

    She looks so young that people mistake her to be the daughter, when she's out with her husband of 54 years, but I suppose he isn't complaining.

    Mrs. Larkins says the secret to her beauty lies in her special diet, consisting of organic vegetables, fruits, seeds and nuts grown in her own garden; she calls it the "fountain of youth". The woman doesn't touch anything that has been cooked.

    And another strange thing she does is to collect rainwater, to keep her garden blossoming, but also to drink. But the residents of Miami-Dade County, Florida, didn't always have such a healthy lifestyle. In fact, she consumed meat regularly, as her husband used to own a meat factory way back in the 1960s. It was then that she decided to change her eating habits forever. And what a great decision that was. I mean, just look at her!

    When she started off, Mrs. Larkins was just looking for a few health benefits and never anticipated that she would look like a 40-year-old at the age of 70. Over the 27 years that she has been eating raw, Mrs. Larkins has written two booklets railed Journey to Health and also produced a DVD containing all her healthy secrets.

    Her husband, Mr. Larkins, wishes he had followed her example, because now he looks much, much older and also suffers from diabetes (糖尿病) and high blood pressure. He takes prescription medicine every day, but Annette doesn't even take an aspirin.

    As the temperature rises, sweaty humans are making a response that is further worsening the problem of climate change. At present, the world just has 1.6 billion air conditioning units, but these units use a surprising total of ten percent of all global electricity supply. While less than a third of families globally are so equipped, the most AC-addicted countries are Japan (in 91 percent of families), the US (90 percent) and South Korea(86 percent).

    New research by the International Energy Agency (IEA) guesses that the total number of AC units is likely to increase to over 5.6 billion by 2050－equal to ten new units being sold every second for more than 30 years－with sales driven particularly by India, China and Indonesia. This will make the use of air conditioning one of the world's largest demands for energy.

    "Growing electricity demand for air conditioning is one of the most critical blind spots in today's energy debate," argues Faith Birol, executive director of the IEA. "With rising incomes, air conditioner ownership will skyrocket, especially in the developing world. While this will improve daily lives, it is quite necessary that efficiency performance be prioritized."

    Birol and the IEA stress the need for new efficiency standards to ensure that consumers are at least buying units that require significantly less power to function, therefore decreasing the total energy demand. Variations on the traditional "vapor compression" technology, which has formed the basis for AC units for more than a century, may appear really important. A water-based system was recently developed by researchers at the National University of Singapore (NUS), which uses 40 percent less electricity and produces only one by-product: drinkable water.

    "Our cooling system can be tailored for all types of weather conditions, from wet climate in the tropics to dry climate in the deserts," says associate professor Ernest Chua at NUS. "While it can be used for indoor living and commercial spaces, it can also be easily used to provide air conditioning for blocks of buildings in an energy-efficient manner."
