The Science of Risk-Seeking

    Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. {#blank#}1{#/blank#} Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.

    The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. {#blank#}2{#/blank#} As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.

    So why aren't we all jumping out of airplanes then? Well, even 200, 000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it.{#blank#}3{#/blank#}

    No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. {#blank#}4{#/blank#} To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

    {#blank#}5{#/blank#} For the risk-seekers, a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

    As experts continue to study the science of risk-seeking, we'll continue to hit the mountains, the waves or the shallow end of the pool.

    Cold blesses us all

    It's November, the time of year when people often get blessed more. This is not because God likes cold weather, nor because others are feeling generous with Thanksgiving just around the corner.{#blank#}1{#/blank#}

    Colds and the flu are the most common illnesses people get in autumn and winter as the weather gets colder. They are all caused by viruses, but colds are generally milder—you'll feel annoyed but not as if you want to die.

    Teenagers catch average six to ten colds a year, according to statistics from the Ministry of Health, while adults average two to four. More than 200  viruses cause cold symptoms.{#blank#}2{#/blank#}You can be contagious（传染的）one day before symptoms develop and for up to five days after becoming sick.

    The signature symptom of a cold is a runny nose. The flu will make you burn with fever, ache all over, feel extremely tired and cough intensely. The flu can sometimes lead to more serious diseases, such as pneumonia.

    {#blank#}3{#/blank#}A doctor can test you to see whether you have the flu in the first few days of the illness. But some treatments for both are pretty much the same:

    {#blank#}4{#/blank#}Many doctors consider water a weapon against the common cold. It helps your blood drive off viruses and flood them out.

    Keep warm. You might be cold one minute and hot the next, and wearing several layers is very important.

    Wash your hands frequently. You don't want to make it worse by spreading the flu to everyone else. Also, avoid sharing cups and eating utensils(餐具) with other people.

    {#blank#}5{#/blank#}But if your flu symptoms get worse, go to a hospital or clinic right away.

A. Most people who catch the flu get better without having to see their doctor.

B. Sometimes, it's hard to tell a cold from the flu based on symptoms alone.

C. Drink lots of water.

D. Taking medicine on time is a good way to prevent the illness.

E. "Bless you!" is a common response to sneezes, the symptom of catching a cold or the flu.

F. Get lots of sleep and take it easy.

G. You can pass on the flu before you even know you have it.

    Public Speaking Training

    Get a coach

{#blank#}1{#/blank#} so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.

    Focus on positives

Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well.

    {#blank#}3{#/blank#}

If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts, walk away! Your brain is so full of what you're going to be talking about.{#blank#}4{#/blank#} As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

    You are a special person not a clone (克隆人)

Most importantly, good public speaking training should treat you as a special one, with your own personal habits.{#blank#}5{#/blank#}Your training course should help you bring out your personality, not try to turn you into someone you're not.

A. You aren't like anybody else

B. You already do lots of things well

    Africa is a very diverse land with many different tribes. One tradition that many of these groups share is painting or marking their bodies and faces in color. They do this for many reasons. Some marks are used to identify people as part of a group.{#blank#}1{#/blank#} Let's look at some different examples of body painting.

    {#blank#}2{#/blank#} Among the Masai of East Africa, when men are old enough to marry and make decisions for their people, they participate in a special ceremony in which they paint their heads and faces red. This ceremony takes place every seven to fourteen years, so there is not an exact age for participating in it. The Samburu, also from East Africa, like to paint their faces and hair red because they think it looks attractive.

    {#blank#}3{#/blank#} To show that he has killed a lion, a man will paint his body with a natural white material, making special marks to represent this accomplishment. The Masai men also use this white to show that they are no longer boys and are considered adults.

    One quite unusual example of face painting is done by the Wodaabe people of West Africa. Once a year, they have a beauty contest for men.{#blank#}4{#/blank#} Then they add white and black circles and lines. Black paint is used near the eyes and on the lips to draw attention to the whiteness of their eyes and teeth, which the Wodaabe consider most beautiful.{#blank#}5{#/blank#}

A.Red is the common color in body painting because it often represents health and long life.
