According to a research， more than 130 billion pounds of uneaten food go to waste in Laura's country each year. That is about 30% of the yearly food supply（供应）. It is a sad fact， especially when you consider how many families and homeless people are in hunger. 

When Laura saw her school dining hall throw away food that was not eaten at all every day， she came up with an idea. She started a project to help her school dining hall to give away uneaten food to homeless shelters（庇护所）in her community. In the past three years， the same project has spread to other schools and some fast food restaurants throughout the city. The project is called Feed & Find， and has already fed thousands of people in her city. 

How does it work？ Through an app， Feed & Find matches local homeless shelters with school dining halls and restaurants that have uneaten food to provide. When dining halls or restaurants have uneaten food left， they can use the app to share the information about the food. A truck driver working for the project is then sent to pick it up and take it to a shelter. 

Pretty cool， right？ It's not surprising that people in other cities have got in touch with Laura hoping that she could help develop similar projects for their communities. 

Some people， however， have concerns about the safety of the uneaten food. They think such food may not be clean enough. Still， this project is a clever way to help solve the problem of food waste and it helps those in need. 

One Sunday， Nicholas， a teenager， went skiing at Sugarloaf Mountain in Maine. In the early afternoon， when he was planning to go home， a fierce snowstorm swept into the area. Unable to see far， he accidentally turned off the path. Before he knew it， Nicholas was lost， all alone! He didn't have food， water， a phone， or other supplies. He was getting colder by the minute. 

Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use. 

He decided to stop skiing. There was a better chance of someone finding him if he stayed out. The first thing he did was to find shelter from the freezing wind and snow. If he didn't， bis body temperature would get very low， which could quickly kill him. 

Using his skis， Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself， like a blanket， to stay as warm as he could. 

By that evening， Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last， Nicholas did the only thing he could—he huddled（蜷缩） in his cave and slept. 

The next day. Nicholas went out to look for help， but he couldn't find anyone. He followed his tracks and returned to the snow cave， because without shelter， he could die that night. On Tuesday， Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow， Nicholas was saved. 

Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls' survival show Man us Wild. That's where he learned the tips that saved his life. In each episode（一期节目） of Man us Wild， Grylls is abandoned in a wild area and has to find his way out. 

When Grylls heard about Nicholas' amazing deeds， he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive. 

Do you ever give up easily in difficult situations？ If so， imagine yourself as someone with great abilities， like Batman（蝙蝠侠）. It will help you feel strong. You will not give up easily and will probably do better. This is called the Batman Effect（效应）

In a study， researchers gave three groups of six-year-old children a difficult task to complete on a computer. In Group One， the children were told—to repeat asking themselves， "Am I working hard？" In Group Two， the children were told to ask themselves the same question in the third person — as in "Is Sam working hard？" And in Group Three， the children were told to imagine themselves as Batman and ask themselves， "Is Batman working hard？" Researchers found that the children in Group Three did the best.

How can you make use of the Batman Effect？ Imagine yourself as someone who is the best for the task you are doing. If you're facing a personal difficulty， imagine yourself as a wise family member. If you're running a race at school， imagine yourself as a top runner. In this way， you can become a little more like the person you wish to be. 

Several years ago I started riding a bike. At first. I thought it was only a 1  ride. But as I built up strength， my friends encouraged me to try some longer 2 . The first one to come along was a 150—mile journey， an event held every year that 3  money to fight cancer. 

When I signed my name， the 4  seemed great — to support a worthy cause while going for the 5 — and I trained with great excitement. But as the time for the ride approached， my 6  gained ground over my endurance （耐力）. I didn't really want to 7  all those miles for two days straight. 

The ride began on a Sunday morning in the Georgia countryside， 8  for the first few hours I felt wonderful. This was just the 9  I had imagined， and my spirits were 10 . 

But by the end of the day， I felt tired. I was sure I'd have to 11 . 

As I topped the hill， the nice sunset 12  me going for a few minutes more. Then in the distance， I 13  a lone rider riding very slowly. I 14  that the person looked different in some way， but I couldn't tell why. I managed to 15 . There she was， riding slowly but steadily， with a 16  smile on her face—and she had only one leg. 

My focus 17  at that moment. I'd been doubting my body for a whole day. But now I knew — it wasn't the body， but the 18  that would help me reach my goal. 

It rained all the second day. I 19  saw the one—legged biker again， but I pushed on without complaining. And at the end of the day， still feeling 20 ， I completed the 150^th mile. 

—Sure. 

—Yes. Next week. I'm preparing for it. 

— Thank you. ____， all the villages here have taken on a new look. 

—Yes. Our IT teacher ____ it. It took him about an hour. 

—Yes. It's a famous Chinese saying by Laozi. 

In the first and second grades, I was extremely shy. I had friends, but it just wasn't in my personality to be very outgoing, even if I knew someone well. I was even quieter with strangers, and so I wasn't very good at meeting new people. I was afraid that I would do or say something wrong.

So in our school's annual grand play, I usually sat in a secluded(僻静的) corner to watch the performance alone. I hoped to sit in the background and watch the actors sweat in front of all those pairs of eyes.

One day in the third grade, my teacher Mrs. Sally called me into her office and said, "Oh, Mary, you're great at memorizing things, and you have such a sweet personality. Perfect for Jenny!" But I bowed my head and dared not speak. The teacher saw this and then said, "Of course, plenty of girls would love the role, and I could find somebody else. But I hope you could try it for me. I had you in mind for Jenny while writing the play! If you really don't want to, I won't force you. It's your choice."

My mind was spinning faster than the windmill(风车) on the school playground. Mrs. Sally, whom I loved and admired, wanted me to play this role. She believed in me. My eyes moved across the room to a poster I had never noticed before. It showed a shooting star and read, "If you reach for the stars, you might at least grab a piece of the moon." I looked into Mrs. Sally's shining blue eyes and said, "Okay, I'll try." I realized it was time to throw off my shy mask and show the world who I really was.

In the following five months, the teacher taught me how to set, put on makeup, memorize lines, create costumes and so on. Gradually, I mastered my lines and songs.

Earthquake can be destructive. Unfortunately, we don't have a (rely) way to predict. But technologies can still help us under such a desperate situation. China is building the world's largest earthquake alert system and it's (possible) the most advanced. Engineers (set) up over 15,000 sensors nationwide and wiring them into a web. an earthquake happens, the sensors can send electrical pulses to the control center and then ordinary people's smart-phones.

The signal travels at almost light speed and faster the earthquake shaking, giving local people a little time to prepare. The system sends messages to people (little) than two seconds after the earthquake happens. It's life-saving. The system, can be the most advanced in many ways, will be the largest earthquake observation network in the world, not only (detect) the movement of the continents but also calculating the possible impact of an earthquake. It will automatically warn local people, making much faster than human observation. The system, overseen by China's Ministry of Emergency Management, is set (complete) by the end of this year.

A few months ago, I was down with a terrible cold which ended in a bad cough. No matter how many different medicines I tried, I 1 couldn't get rid of the cough. Not only did it 2 my teaching but also my life as a whole.

Then one day after class, a student came up to me and 3 traditional Chinese medicine. From her description, Chinese medicine sounded as if it had magic power that 4 . I was 5 because I knew so little about it and have never tried it before. 6 , my cough got so much worse that I couldn't sleep at night, so I decided to give it a 7 . The Chinese doctor took my pulse and asked to see my tongue, both of which were new experience to me because they are both 8 in Western medicine, where diagnosis relies heavily on 9 . Then the doctor gave me a scraping(刮) treatment known as "Gua Sha". I was a little 10 at first because he used a smooth edged tool to crape the skin on my neck and shoulders.

A few minutes later, the treatment started to produce a 11 effect and my body and mind began to sink deeper into 12 . I didn't feel any improvement in my 13 in the first couple of days, but after a few more regular visits to the doctor, my cough started to 14 . Then within a matter of weeks, it was completely 15 !

Nearly everyone is shy in some ways.  You can build your confidence by following some suggestions from doctors and psychologists.

What you have to say is just as important as what other people say. And don't turn down party invitations just because of your shyness.

Prepare yourself for being with others in groups.  Then make a list of ideas, experiences, and skills you would like to share with other people. Think about what you would like to say in advance. Then say it.

If you start feeling self-conscious in a group, take a deep breath and focus your attention on other people. Remember, you are not alone. 

No one ever gets over being shy completely, but most people do learn to live with their shyness.  They work at fighting their shy feelings so that they can face the cameras and the public. Just making the effort to control shyness can have many rewards. But perhaps the best reason to fight shyness is to give other people a chance to know more about you.

When you walk with a backpack, do you know how the things inside move from side to side? Now scientists have figured out how to tap into that movement to produce electricity.

Picture a pendulum(摆锤) fixed to a backpack frame and stabilized with springs on either side. The pack's weight is attached to the pendulum, so the pendulum swings side to side as you walk. Then a machine is driven by that swinging movement, and produces electrical current to charge a battery.

Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O₂, and CO₂. When the volunteers were walking with the slightly swinging 20-pound load, the device did not significantly affect their metabolic(新陈代谢的) rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of acceleration they'd feel in a regular pack, which might mean greater comfort for a long hike. And the device did produce a steady trickle(涓流) of electricity. If you up the load to 45 pounds, it could fully charge a smartphone only after 12 hours. The details are in the journal Royal Society Open Science.

The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices. It is particularly useful to those who work in remote areas, as these people often carry a lot of weight in a backpack for their exploration.

But here's a real conundrum: the energy-harvesting device currently weighs five pounds. The researchers say that's about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load so that they can ensure the pack charges your phone up without weighing you down.
