A law was made by French government． It made France the first country in the world to prevent supermarkets from throwing away unused food． Now supermarkets of a certain size must donate unused food， or they will face a fine． There are other rules requiring schools to teach students about food sustainability （可持续性）． They also ask companies to report the food waste numbers in their environmental reports． And restaurants should provide take﹣out bags．

"These laws make it a standard to reduce waste．" says Marie Mourad， a student in Paris who has written several reports on French food waste． "France is not the country that wastes the least food， but Frenchmen have become the most active because they want to be the example in Europe．"

"Preventing supermarkets from throwing away food means a lot，" says Jonathan Bloom， a famous writer． "This step has influenced parts of French food industry．"

It is everyone's duty to fight against food waste． Everyone should pay attention and take action．

With the development of modern technology， digital devices（数码设备） have been seen everywhere． People often check what is h【1】 in the world on the Internet， keep in touch with friends through emails， or even start to read e﹣books． H【2】， many people still prefer paper books to e﹣books because they think that brains work b【3】 when reading paper books．

Now， some scientists have come up with some d【4】 ideas． They believe how brains work is not greatly affected by the way people read， but depends on the following factors（因素）． They I【5】 the type and content of reading materials， the p【6】 of reading． etc． When people read for entertainment， like news about star families or f【7】 stories， reading paper books or e﹣books makes no difference． When people read to gain k【8】 about science， reading paper books is more helpful． Brains need longer to deal with harder problems． Usually， taking notes by h【9】 on paper books takes longer than typing（打字） notes out on digital devices． So it's e【10】for you to remember key points when you read paper books． Next time， when you read e﹣books about science， just remember to slow down and give your brain more time．

Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie′s place. We′d sit on the edge of the dock(码头), feet dangling(摇晃), and got ready for a big meal.

Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we′d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.

Bernie was my father′s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie′s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.

What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don′t take the time to dangle your feet over the dock and enjoy life′s small pleasure, your work is probably hurting your life.

For many years, I forgot that lesson I′d learned as a kid on the loading dock. I was too busy making all the money I could.

Well, I′ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That′s the heart of the watermelon. I have learned again to throw the rest away.

2.Exercise after work．

Don't go home first． Few people are so motivated（有动力的） that they will go out again and exercise after they go home and change clothes．

Tiredness is not an excuse． While exercising， you breathe deeply and your body makes better use of the oxygen exchange． Then， you will feel energetic．

4.Notice that you are better than before．

It's great when your clothes fit better， you can lift heavier things or take exercise longer． There's something good too， like getting a good night's sleep or thinking more clearly．

Not everyone can start out with 10，000steps a day． Use a pedometer， and find out your daily steps． And then， try your best to walk 300extra steps each day． Finally， you can reach 10，000steps a day．
