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.

    Experts are always advocating the health benefits of biking. And while the barrier to entry is low-pretty much all you need to know to start cycling is how to ride a bike itself-people often ask me if I have any tips for beginner bikers.

    Below, a few things I've learned along the way that help make for a safer and more joyful ride:

    Follow the rules of the road. Brake at yellow lights, stop for pedestrians and maintain a solid distance from cars.{#blank#}1{#/blank#}Therefore, never fly through stop signs, approach too close to the front vehicles or shout at cars.

    {#blank#}2{#/blank#}A British doctor recently made headlines when he claimed that wearing a bike helmet is actually more dangerous than traveling without one, but most research suggests otherwise. A full 98 percent of bike commuters （上班族）own a helmet, so you'll be in good company, anyway.

    Make a playlist. Laws against riding with headphones vary from state to state, and it's never proper to listen to music in more than one ear. But cruising around to a soundtrack can be an amazing feeling, so consider buying a wireless speaker you can fix on your frame.  {#blank#}3{#/blank#}

    Know your rights. If you do end up getting into a collision, stay on the scene until the police come.{#blank#}4{#/blank#} Cyclists are too often taken advantage of in bad situations, especially if their injuries don't seem to be apparent.

    Find some friends. As great as it can be to bike alone, zipping down the street in a big group is an equally satisfying experience.{#blank#}5{#/blank#}Various bicycle trips are often organized, which provides opportunities to develop friendship among bikers.

A.Be sure to get a helmet.

B.It's necessary you give them an accurate report of the incident.

C.Most cities have enough resources for the cycling community.

D.Most of us will feel it obviously safer to ride on a bike than in a car.

E.Then put together a list of your favorite tunes and get ready to enjoy them.

F.Pushing to the limit not only gives bikers a bad reputation, but also a great danger.

G.It' s comforting to know that whatever I need is nothing more than a bike ride away.

    How to prepare for exams?

    Here are some tips you can read with your child.

    The first step in preparing for examinations is to set a fixed time each day to study and a schedule to say when to start the revision and for which subject. The plan should include how many chapters to revise and how many worksheets (活页练习题) to work on. {#blank#}1{#/blank#} Parents who do not know the examination schedule can search “exam timetable” to see the official examination schedule. {#blank#}2{#/blank#}

    The second thing is to decide on the place to study. Some need total silence in a library before they can concentrate while others like to have some background music like in the cafeteria, {#blank#}3{#/blank#}So there is no need to tell your child to change the study place if he is producing the desired results.

    {#blank#}4{#/blank#}For lessons, pupils must participate in lessons and discussions actively. For exercise, work on the simple ones in the textbook. For theory, pupils can use the mind map method to summarize the facts.

    At last, be smart. Focus on chapters that are the core of the subject or difficult chapters. {#blank#}5{#/blank#}

A. Next the most effective way to revise is to use an active approach.

B. Making good preparations counts.

C. The mind map can help you a lot in your revision work.

D. Your child has to be self-disciplined (自律的) to follow the plan.

E. It is not necessary to read from the first to the last page.

F. The best time to start revision is one or two months before the examination.

G. Both are alright as long as your child is comfortable with it.

    China has been the birthplace of many of the world's greatest inventions. It was, for example, the first country to produce paper money. Before the invention of paper money and coins, people used many different kinds of things for buying and selling{#blank#}1{#/blank#}This exchange of goods and services for other goods and services is called bartering.

    {#blank#}2{#/blank#}In 1200 BC, people in China began to use shells (贝壳) as money. Usually the shells used as money were very small. This made it easier for people to carry money over long distances, and allowed for trade to develop between different parts of the country.

    In the years which followed this invention, many other countries around the world began to do the same.{#blank#}3{#/blank#}

    The next development was in 1000 BC, when China started making bronze and copper shells. It wasn't long before the Chinese made round coins out of metal.{#blank#}4{#/blank#}By 500 BC, metal coins had begun to appear in countries like Persia and Greece, and later in the Roman Empire.

    About 1,000 years later, leather was used as money in China, and in 806 AD, the first paper banknotes were produced by the Chinese people.{#blank#}5{#/blank#}

A. People also began collecting foreign coins as souvenirs.

    Everyone is aware that taking good care of our bodies can prevent many medical problems from occurring later.

While our mental health may be fine right now, many of us will struggle at some point. {#blank#}1{#/blank#} It's impossible to get through life without challenges, but our mental health prevention habits can help us get through difficult times. {#blank#}2{#/blank#}

    Keep active. The more active you physically, mentally and socially are, the higher the level of your mental wellness is likely to be. So go for walks and learn something new. There are many other ways to be active. {#blank#}3{#/blank#}

    Be connected. Regular involvement in social activities with supportive friends and family improves your ability to handle disappointments, and everything else life throws at you. {#blank#}4{#/blank#} But you can be involved in any manner; even volunteering for an organization can help you be more social.

    {#blank#}5{#/blank#} The nature of these activities varies widely from person to person. The key is to identify what gives your life meaning. Volunteering, coaching, teaching, etc. all can contribute to increasing your sense of confidence and satisfaction with life. Many activities can address more than one. The key is to make a plan and stick with it. If you are already struggling, begin to practice these ways to help your recovery.

Taking photos while on holiday is not an uncommon activity. Tourists do it all the time, but if you want to take things further, here are some tips that can help you along the way.

First of all, there is the matter of equipment. Of course, most people believe that the higher end your camera is, the better the photos will turn out. {#blank#}1{#/blank#} The quality of DSLR cameras (数码单反相机) is superior to the one of small cameras and smartphones, but only if you know how to adjust (调整) their settings. However, if you don't know how to do it, an iPhone camera is enough too. {#blank#}2{#/blank#}You can shoot amazing photos without having to travel with a large and heavy camera.

Secondly, you need to do some research in advance and discover the best photo spots. Your photos don't have to look like travel cards. On the contrary, you can catch the beauty of a place by finding its uncommon corners and subjects. For example, if you're going to a crowded city, don't just take photos of high buildings. {#blank#}3{#/blank#}You may see a new face of the city at that time.

Thirdly, you have to be patient. {#blank#}4{#/blank#}For the best picture, come back to the same spot several times or stay at one spot for some time. You might come across something special as you wait: a bird flying across an old temple, a mother and her baby passing by, or just the sun giving beautiful colors on the roofs. {#blank#}5{#/blank#}

Take as many photos as you can and don't be disappointed if your first travel photos are not National Geographic material, because they will get better with time.

A. So this is the most important.

B. But that is only true in a way.

C. Its quality has increased a lot.

D. Don't forget that practice makes perfect.

E. I also enjoy photographing animals.

F. You may have to take several shots until you discover the right one.

G. Try street photography or take pictures at night.
