What will you do if you can't eat everything bought in the canteen?{#blank#}1{#/blank#}According to a survey, what students waste every year could feed over 10 million people.

    {#blank#}2{#/blank#}According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people.

    Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the West, for instance, consumerism, the belief that it's good to use a lot of goods and services, is often to blame for food waste.{#blank#}3{#/blank#}Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil others go through in order to provide them with the food they eat.

   {#blank#}4{#/blank#}There are 925 million hungry people in the world. They don't have enough food to eat. And farmers work very hard to grow the crops.{#blank#}5{#/blank#}It's also important that everyone thinks about how they can do their bit to reduce food waste. Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.

A. Students waste is extremely serious,

B. To reduce food waste is a big task, and it needs time.

C. China, in turn, features its own eating culture.

D. But canteen waste is merely the tip of the iceberg.

E. So we shouldn't waste our food.

F. Students can never realize the serious food waste situation.

G. Most of us would simply throw away any leftover food.

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 al 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.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.

    Good learners can inspire students or anybody to learn well. Here are some characteristics of good learners.

    Good learners are curious. They wonder about all sorts of things, often about knowledge beyond their areas of expertise(专长). {#blank#}1{#/blank#} Finding out about something they didn't know satisfies them for the moment, but their curiosity is addictive.

    Good learners don't give up easily. A few things may come easily to learners but most knowledge arrives after effort. {#blank#}2{#/blank#} They try to search out new information. They read, analyze, and evaluate the information they've found. Then they study more and work at what they don't understand.

    Good learners know that a lot of learning isn't fun. The journey to understanding generally isn't all that exciting. {#blank#}3{#/blank#} Others need a tiresome attention to detail, and still others need periods of intense mental focus. Your backs hurt, your arms and legs get tired, and your coffee gets cold.

    {#blank#}4{#/blank#}There's always more to know. Good learners are never satisfied with how much they know about anything. They are pulled around by questions—the ones they still can't answer, or the ones without very good answers. Those questions follow them like day follows night with the answers bringing daylight.

    Good learners share what they've learned. Good learners are teachers committed to sharing with others what they've learned. {#blank#}5{#/blank#} Good learners can also explain what they know in ways that make sense to others. They are connected to the knowledge passed on to them and committed to leaving what they've learned with others.

A. Some learning tasks require boring repetition.

B. Good learners are willing to put in the time.

C. Some knowledge can broaden our views.

D. Good learners stay positive.

E. They write about it, and talk about it.

F. They love the discovery part of learning.

G. Good learners never run out of questions.

Being a superhero to others

    Ewan Drum has always liked superheroes. He likes how they help people. At age seven, he told his parents, “I want to dress up like a superhero and help the homeless.” {#blank#}1{#/blank#}Wearing his red superhero cape (斗篷), Ewan helped pass out 70 bag lunches to hungry people in a park in Detroit, Michigan. That's how Super Ewan was born.

    {#blank#}2{#/blank#}People donated(捐赠) money and supplies (供给物), and Ewan took them to those in need.

    When someone donated jugs(大罐) of water, Ewan and his family drove their car to get even more. They took the water to Flint, Michigan, a city that had unsafe drinking water. Another time, a businessman donated six turkeys(火鸡) for Thanksgiving. {#blank#}3{#/blank#}“In the end”, he says,“ we gave 64 turkey dinners to families all around Detroit.”

    Ewan has a motto: Everyone can be a superhero to someone. At an event called the Hero Round Table, Ewan told the audience, “It's not hard to help people. You can keep some socks and food in your car to help people in need. You can help a neighbor with doing the garden. {#blank#}4{#/blank#} ”

It's been several years since Super Ewan started his task. Every month, he still visits the same park to hand out clothes, food, and supplies to people who are hungry or homeless —his Super Friends. {#blank#}5{#/blank#}

    “No matter what, ”Ewan says, “I will always keep helping people.”

A. News spread about Ewan's act of kindness.

B. This superhero says he'll never take off his cape.

C. Ewan says he wants more adults to act like superheroes.

D. Every little thing helps and can make someone feel happy.

E. A few months later, Ewan's family planned a day of giving.

F. Several days later, his parents drove to Flint and helped him raise a lot of money.

G. With his parents' help, Ewan asked for more turkeys through the Internet, plus side dishes.

    In the middle of my home country there are very large places. They are hot and dry land called deserts.

    {#blank#}1{#/blank#} Families live a long way from other people. Sometimes they are the only people for thousands of kilometres. {#blank#}2{#/blank#}

    About 65years ago these people found that using strong radios was a possible way for families living far away to communicate with each other. They decided they could use the radios for school. In this way, children could talk to each other like at school. {#blank#}3{#/blank#}

    The children each spent about 30minutes a day on the radio. They talked to their teacher about their work and difficulties. The teacher designed some exercises and tasks based on what they learned and posted them to the children. After finishing their work, the children sent it back to their teacher to mark. {#blank#}4{#/blank#} He tried to visit each child twice each year. This was sometimes difficult. The journey was very long and could be dangerous. In addition, the school held camps once a year. The children could all meet each other and shared their learning experience.

    {#blank#}5{#/blank#} The government provides families with computers so that the children can use the Internet to talk to their teachers and classmates by e-mail now. The teachers enjoy their work very much because they get to know the children and their families very well. It is an interesting way to learn, don't you think?

    Life is difficult to everybody, so you need to organize your life well. Here are some suggestions which might give you some help to manage your life well.

    Write everything down and do not rely on your memory. {#blank#}1{#/blank#} If you want to remember things, put them in writing, or in a digital notebook. Keeping your to-do lists and other information written somewhere allows you to look back at them anytime, especially when you have hit your head and forgotten some of them.

    {#blank#}2{#/blank#} Try this experiment before buying one thing, throw out something old or something you do not use. Or, if you are a really pack rat (不想扔任何东西的人), just throw out one old thing a day until you can not find any more items to throw.

    Recycle and donate. Is your closet full of unopened bags and clothes that still have their tags (标签) on? Is your bookshelf full of unread books? Chances are that if you have not read, worn, or used whatever they are, they you are probably not going to use them at all. {#blank#}3{#/blank#}

    Create daily, weekly and monthly timetables for cleaning. Organize your cleaning timetable. {#blank#}4{#/blank#} Distribute tasks properly, so for example, dish washing could be done daily while vacuuming (吸尘) could be done weekly and cleaning the windows done monthly. Whichever of these tasks you decide to do, remember that you can not completely organize your life in one go (一口气).

    {#blank#}5{#/blank#} Just decide to get organized now, and then take baby steps. Soon enough, you will be making a habit out of it all.
