When it comes to benefits of volunteering, a lot of people think it's all about the warm feelings after helping someone. {#blank#}1{#/blank#} For example, volunteering...

1）Teaches you new skills

    From helping make websites to teaching kids languages, to arranging events for charity, volunteering can really be almost anything.{#blank#}2{#/blank#} And through overcoming these you learn and start to master completely new skills.

2）Can be relevant work experience

    Something that seems to stop many is that experience often seems to be a prerequisite (必备条件) for some jobs.{#blank#}3{#/blank#} There's many a journalist that gets his or her start through volunteering for a college or university paper, and that's not at all the only profession this applies to.

3）Can be therapeutic (治疗的)

    One of my close friends has completely transformed since she started working for disabled kids.{#blank#}4{#/blank#} It allows you to see the world and other people from a whole different point of view, which in turn can make you grateful for what you already have and see your own personal value.

4）Helps you expand your network

    One of the great things for volunteering is that you meet a wide variety of people.  {#blank#}5{#/blank#} Sometimes it's very convenient to have a broad network.

A. Volunteering helps you grow as a person.

B. As it turns out, that's far from the only benefit.

C. Volunteering can actually help you get the experience you need.

D. Volunteering helps you look outside yourself and your problems.

E. It's a way to prove that you've not just been sitting and doing nothing.

F. That means when you get involved in voluntary work, you will face many challenges.

G. You're getting to know people involved in many different walks in life that you wouldn't have had the opportunity to meet otherwise.

    Do you often feel lonely? What do you do when you feel that way? Hide yourself away and spend your time reading, watching TV or walking around?

    You might think that feeling lonely is just like feeling happy, sad or scared — that it's just one of your various moods. That is true. However, if you let yourself be lonely for too long without dealing with it, you could be making a serious mistake.

    Doctors have known for some time that feeling lonely is bad for the mind. It can lead to mental health problems such as depression, stress and reduce confidence. "Being lonely means not feeling connected or cared for, but it's not about being mentally alone," Lisa Jaremka, scientist from Ohio State University, US, told Live Science in January. And there's growing evidence that not having friends is connected with physical illness as well.

    In 2006, for example, scientists studied 2,800 women who had cancer. They found that those who had few friends or family were five times more likely to die of their disease than women with many social contacts. Also, even healthy people had a better chance of falling ill if they felt left out by others, according to the BBC.

    The results have scientists thinking that loneliness might hurt the immune system（免疫系统）, which protects the body from diseases.

    Hoping to prove this theory, Jaremka and her research team put volunteers（志愿者） through a stress test. During the test, volunteers were asked to make an unprepared speech in front of a group of stony-faced people. The researchers found that volunteers who said they were lonely in their daily lives felt more stress during the test. And their blood samples showed that all the stress had managed to cause harmful changes to their immune system.

     "Loneliness has been thought of in many ways as a chronic stressor（慢性增压器） — a socially painful situation that can last for quite a long time," explained Jaremka, who led the study.

    The number of people suffering from loneliness is increasing all over the world. However, solving the problem is easier said than done. It won't work to just "tell anyone to go out and find someone to love you", said Jaremka. "We need to create support networks."

    He looked like a pirate.

    With his handkerchief tied in a knot behind his little nine-year-old head, he looked like a pirate, a sad pirate. The first time little David came to our camp, he was hairless and worn out from medical treatments. He was also very angry.

    Paul Newman's camp counselors (指导老师) were hoping to fill David's days with fun and laughter. But David stayed inside himself, wanting to be alone, or in a corner of the cabin. At this camp for children with life-threatening illnesses, we had seen some pretty tough children worn out by cancer recover full of energy despite their illness. But we saw little progress in David no matter what we tried with him. Five days into the eight-day session saw a quiet, sad little pirate.

    Then something happened on that fifth night. Something at camp that we would call "huge". It was cabin night. That's the time when campers and counselors spend time together in each individual cabin instead of an all-camp activity. Campers love cabin nights because there's always a bedtime snack. On the cabin table that night were bags of potato chips.

    David slowly walked over to the table, leaving his comer to join the rest of us. He took one of the bags of the potato chips and started smashing(弄碎) it with his little fists, as all the other campers looked on in disbelief, I wondered what the cabin counselor would do.

    The college-age volunteer counselor positioned a bag of chips on die table in front of himself, and he, too, started smashing it with his fist. The campers went crazy as everyone ran to the table to get in on the fun of smashing potato chips with their fists.

    Somehow everyone knew, everyone sensed, that anger within him was now being released.

    For the last couple days of the session, David was a different kid. He was a little nine-year-old boy again, trying to fill the hours of each remaining day at camp with as much fun as could be possible.

    Several days after the session, David came back again. This time, there wasn't anything he wouldn't try to fit in to his day. He sure was having a great time at camp. David asked me if I needed an altar(祭坛)boy when I celebrated Mass in the woods. Sure enough, he was my altar boy. I remembered how carefully he listened to me when I talked about death. I said it's only a doorway. You walk through the door and there's the Lord God and behind God a whole line of people waiting to hug you.

    After Mass, he said to me, "Hey Fatha, a door, huh?"

    A couple more days of fun passed and tonight was the talent show. The tradition is that campers and counselors dress up in costumes, and everyone gets a standing applause for singing and dancing or simply just acting like fools on stage.

    The show had begun: lights, camera, action.

    Unfortunately, the only action taking place in our row of seats was little David making his way from counselor to counselor to say an early good-bye to camp. He had become quite ill and had to go to the hospital because of this new crisis.

    When this little nine-year-old pirate stood in front of me, he gave me a hug and a big wet kiss on my cheek. I was crying. He was crying. A whole row of counselors was in tears. After the hug and kiss, he put his hands on my shoulders, and tears still in his eyes, said: "See you on the other side of the door, Fatha."

    Modern day robots may not be as entertaining as R2D2 or the robot from Lost in Space, but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.

    Robots make great explorers on planets, moons, and other landing areas. Aside from the earth, just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient fortunate for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be complications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.

    Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, to finding water are all performed much quicker and accurately by robots.

The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough | food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never complain, they don't require food or water, and they never need a bathroom break.

    Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.

Confidence Comes From Treating Others As Equals

    There's been recent discussion over Chinese attitudes toward foreigners, caused by another quarrel between a foreigner and a taxi driver. According to the studies described in the Oxford Handbook of Chinese Psychology, Chinese have lower self﹣confidence compared to Westerners. Yet does the result still apply to the Chinese people today？

    Yes and no. For the moment, different attitudes toward foreigners can still be found in China's society, with some displaying low self﹣confidence like "Foreigners are awesome （令人敬畏的）, and Western countries are awesome. We should respect them and be as polite as possible, and shouldn't let them look down on us, " and a few unfriendly opinions such as "Some foreigners are rude and disrespectful, and their level of civility （礼貌） is far behind China."

    Chinese used to be lacking in self﹣confidence. It might start from the modern history, after the failure in the Opium wars, and the following humiliation （耻辱） of being bullied （被欺负） and brought to their knees by Western guns. And the dark history is still to some extent affecting our mentality （心态） today.

    For some time, the Western world represents the best of everything in some Chinese eyes. But our state of mind is gradually changing. When asked "What makes you feel proud of your country？" in school classes in China, answers vary from the World Expo to the Olympic Games, from athletes to astronauts, from the mushrooming skyscrapers to busy metropolises, which have all filled us with growing self﹣confidence.

    While answering the question "Since China is so good today and Chinese people are more confident, why are an increasing number of Chinese emigrating abroad？" Zhang Weiwei, a professor at Fudan University, replied that at least 70 percent of Chinese migrants （移民） become more patriotic （爱国的） after leaving their home country, no matter whether they have become a naturalized citizen of another nation or not. Such result and experiences are much more convincing and have better effect than dozens of "patriotic education" classes.

    There is no reason for us not to be self﹣confident. We live in the world's second﹣largest economy. Chinese net financial assets per capita （人均纯金融资产） and the purchasing power of people have seen a sharp rise, with more and more people starting to purchase works of art, instead of only necessities. These all indicate a rising standard of life and self﹣confidence.

    Nevertheless, the point of the changing attitudes toward ourselves or other countries is not realizing other nations are better or worse than China, but treating them like how we treat our fellow Chinese. That is what confidence means, not being condescending （屈尊）, not worshiping, but looking each other in the eye with trust and respect.

    In the waters off Brisbane, Australia, a seven­foot­long sand tiger shark swims in pain. A two­foot­long spike sticks out of her side. It's a piece of fishing equipment that the shark ate carelessly. After traveling into her body, the spike punctured(刺) through the shark's stomach.

    A man swimming in the water notices the shark. Then, he warns Sea World Marine Park in the nearby town of Gold Coast. Sea World sends a 12­person team from its rescue center to where the shark was discovered in Moreton Bay Marine Park. Soon, they find her lying on the seafloor. "She'll die without help，"says Trevor Long, leader of the rescue center.

    Using an onboard crane(吊车), the rescuers move the shark into their boat's 13­foot­long tank(缸). Then Dr. David Blyde gives the shark pain medicine and performs an operation to remove the spike. After that, the team sails with the shark to Sea World 33 miles away. They place the fish in a 49­foot­long tank and wait to see if she gets better.

    To give the shark's stomach time to get better, she isn't fed for the first few days. A week after her operation, Long offers the shark a small, dead fish. The animal refuses to eat. But days later when he drops another fish into her tank, the shark enjoys her meal. By now the shark's wounds are getting better.

    Two weeks after her rescue, they take the shark back to the boat and return her to Moreton Bay Marine Park. As the fish is lowered by the crane to the water's surface, two rescuers jump into the ocean and guide her into the sea. From the boat, Long watches her swim away." The shark has another chance," Long says.
