写作思路：首先点题，简述以往民以食为天到现在人们忘记食物的本来意义，通过叙述过节，表妹浪费粮食，大人们的态度，以及自己的感受，说明要节约粮食。
正文：
From the previous "yen" gradually with the development of The Times gradually
evolved into "people in food more and more odd variety of food on our
table, let everybody forget about food's original meaning.
从以往的“民以食为天”随着时代逐渐的发展渐渐演变成了“民以食为乐”越来越多新奇古怪花样百出的食物出现在我们桌上，让大家渐渐忘了食物原本的意义。
At the feast, the family often to visit a lot of people, up traditional dishes served
up, old people's eyes are full of smile and satisfaction, and the child is beside the
mouth with chopsticks muttered: "how is the food."
逢年过节，家里常常来了许多人做客，一套套传统的菜被端了上来，老人们的眼里都布满了笑容和满足，而小孩子却在旁边拿着筷子嘴里嘟囔着：“怎么又是这些菜呀。”
Remember that day, when served the food on the table, her cousin began to
complain: "tired of the food ate so many years early, we go out to eat
KFC，McDonald's." Table was drumming knock to ring, grandma and grandpa some angry.
记得那天，当桌上端上了菜，表妹就开始抱怨：“这些菜吃了那么多年早腻了，我们出去吃肯德基麦当劳。”桌子被敲得咚咚地响，爷爷奶奶有些生气了。
brow displays a vicissitudes of life eyes stared at the several courses, eyes drifting far a
way: "the children ah, you now just thinking of all day to eat good, in fact, some have
been very good to eat, think that year again we would eat meat are not always have！"
眉间显露出了一股沧桑感，双目盯着那几道菜，眼神飘得很远：“你们这些小孩呀，现在整天就想着吃好的，其实有的吃就已经很不错了，想当年我们那会吃饭吃肉都不是顿顿都有有的呀！”
Sat on a side of the adults are also beginning to argue that: "mom and dad, now is the
21st century, old-fashioned things don't always say to the children, the
children, always want to eat some good, human nature. The past is the past don't want to."
坐在一旁的大人们也开始议论道：“爸妈，现在是二十一世纪了，不要老是跟孩子们说旧时代的事，孩子们，总想着吃些好的，人之常情么。过去的就过去了就别再想了。”
Grandparents listened to, look a bit awkward and disappointed, helplessly shook to
shake, "said is right, but.." "Good good, don't say that." Words haven't say that finish
is interrupted, they sighed deeply.
爷爷奶奶听了，神情显得有些尴尬和失望，无奈的摇了摇手：“说的是这样没错，但是……。”“好了好了，别说这些了。”话还没说完就被打断了，他们深深地叹了口气。
Finished eat, left a lot of leftovers on the table, looking at these dishes, grandma
and grandpa want to say something but did not say anything or hesitant, quietly sitting
next to her at the same time I seemed to hear the sighs.
饭吃完了，桌上剩许多剩饭剩菜，看着这些菜，爷爷奶奶想说些什么但还是犹豫着没有说什么，安安静静地坐在旁边同时我仿佛又听到了他们的叹息。
Sitting next to me listen to you pour out, think of the articles in the book to
see, which have better life now, those who are affected by war of aggression, they are
not the same as grandpa's grandmother that generation.
坐在一旁的我听着大家的絮絮叨叨， 想到在书上看到过的文章，现在的生活哪有好转，那些受到战争侵略的人呢，他们不是跟爷爷奶奶那辈一样么。
Many people do not have enough to eat lunch because of the war, they don't have
the heart to want to eat good, because they are somewhat extravagant eat. Although
we are now living standards have improved, but also can't think of oneself
everywhere, maybe save a little food to save a little food to save a little water, those
people won't show so poor.
许多人因为战争饭都吃不饱，他们没有心思去想吃好的，因为他们却连吃饭都显得有些奢侈。尽管我们现在的生活水平都提高了，可是也不能处处都想到自己啊，也许节约一点食物节约一点水资源，那些人民也不会显得那么乏了。
提到粮食，你一定会想到香喷喷的米饭，好吃的馒头吧！粮食对于我们每个人来说都是必不可少的，它不仅能解决我们的温饱问题，还能为我们的身体带来最基本的营养和能量！
When I was sensible, my parents taught me to be diligent and thrifty, and cherish every grain of rice and every drop of water! "Who knows, every grain is hard." Every grain is earned by the farmer's uncle's hard work. To love and save grain is to respect the farmer's uncle's labor. We should not only start from ourselves, but also drive people around us to cherish and save food.
从我懂事时，爸爸妈妈就教导我要勤俭节约，要珍惜每一粒米，每一滴水！“谁知盘中餐，粒粒皆辛苦”每一粒粮食都是农民伯伯辛勤劳动换来的，爱粮节粮就是对农民伯伯劳动的尊重！我们不仅要从自身做起，还要带动身边人爱惜、节约粮食。
I summed up some food saving tips:
我总结了几点节粮小窍门：
When cooking and buying food, you should calculate the number of people who eat and calculate the amount you need
1、平时做饭买菜时要适量算好吃饭的人数计算好需要的量。
When eating, eat as much as you can, and try not to leave any food.
2、吃饭时，吃多少盛多少，尽量不剩饭菜。
When you eat in a restaurant, you should order properly, don't waste it, and take it home when you can't eat it.
3、在饭店吃饭时点菜要适量，不要浪费，吃不完的打包带回家。
Develop the habit of not being picky eaters or partial eaters, which can not only nourish your body, but also avoid the hidden danger of waste.
4、养成不挑食、不偏食的习惯，既可以让自己的身体得到营养，同时也避免了浪费的隐患。
Save food and love food, starting from me, starting from my side and starting from now.
5、节粮爱粮，从我做起，从身边做起，从现在做起。
Have you found that there are a small number of students who threw rubbish about after eating their fast food these days. They threw the packing boxes or paper everywhere in the school yard--on the corridor, on flight of steps, under stairs, on the playground, in the lawn, on the bush, under the wall, into the pool and so on…What was worse, some students put the rubbish into others' bike-basket. I think it is a bad phenomenon. Not only will it do harm to our health, but also it will do harm to students' moral upbringing.
So I think it is necessary for us to do something to put a check on this kind of behavior. We can tell teachers if we see someone who throws the rubbish, or we can go up to him and tell him it is not good to do that.
Such goings on will have to stop!
范文二：停止浪费粮食
People should feel sorry for themselves when they wasting something that they possess.for even though most of us leading a good life nowaday's,but there are still some people spending suffering life.when we enter Mcdonald's and KFC to eating our luxury food,yet they just expecting some food to get rid of their starvation.
Like all the parent's said their suferring past day's,we can imagine that 30 year's before they also had spent those day's,witch we can understand from our parent's faces appearances.
范文三：停止浪费粮食
Whenever we saw in the trash only had one bite of bread, she saw her classmates did not finish the meal, what would you feel? Are we really that adequate food, inexhaustible it?
No, no. There are still 100 million people to eat food and starving with. Africa, Americas, Asia and even Europe has. We count an account, about 1.3 billion Chinese people, waste of one meter per person per day if a week is wasted 9.1 billion meters, a month wasted 39 billion meters, a year as a waste hill high pile of rice. If you save one meter per person, it can greatly reduce China and the world's food supply difficulties.
Our school's restaurant, on the leftovers while filling the swill bucket, watching a great pity. Although the restaurant wall plastered to cherish the food cues, can be and who would really do it? Lip wasting food is a shameful act, he is not the same as in the waste?
Maybe you did not realize they are wasting, that of the motherland with vast land, waste that does not matter. However, China's population of about 1.3 billion, net annual growth is 12 million; per capita arable land area of ??1.2 acres, is the world's per capita value of 1/4; urban population consumes 40 percent of the country rely on imported food. Unauthorized occupation of cultivated land, dredging, land degradation, desertification and other phenomena in the encroaching farmland, our food come from? Is grown by the farmers!
Save food, start from everyday life: how much to eat a meal containing the number, do not throw leftovers; a la carte meal in a restaurant in moderation, eat the food packaged to go home, can not be wasted. Students, let us act together, you and me from the start, so to save food no longer be an empty promise!
范文四：粮食浪费
How many times I have seen a company or organisation habitually waste good food?! Too many times! They are well-meaning people, and they'd like to give away the food instead of wasting it by putting it in the dustbin. They'd maybe like to give the food to the needy or the poor, and there's probably a few beggars just along the road if anyone was kind enough to go along and see if they are hungry.
很多时候我经常看到一个公司或组织拥有好的食品意识而不去浪费粮食？！很多时候，他们都是好心人，他们想丢弃的食物，而不是浪费它，把它放在垃圾桶。也许他们会想给有需要的人士或穷人的食品，有可能是沿路的乞丐饿了会一路去寻找热心人丢弃的食物。
So why don't they do it? Reason: Too many stupid rules! Just as surely as there's no pig bin anymore for food to be recycled as pork (because of various illconceived ideas about the health of pigs if they eat other people's sunday lunches and leftovers), there's no "well let's give it to the beggars!".
那么，为什么他们不这样做呢？原因是：太多的愚蠢的规则！只是作为一定会为有是没有猪槽以将猪肉（因为对猪的健康各种的想法，如果他们吃其他人的星期日午餐和剩菜）回收的食物了，那里是没有“好让的给它的乞丐！”。
Apparently, beggars can in theory take the company to court if they are made ill by the food. Not that they are seriously going to be made ill by perfectly good food, and not that most beggars have the money to start a legal case.
显然，如果乞丐因为食物生病了他们会将公司告上法庭。并不是好的食品使他们生病，并没有很多乞丐有钱启动一个法律案件。
"when the farmers worked hard to hoe and harvest at noon, sweat fell into the soil under Wexia. Who knows that every grain on the plate is the hard work of the farmers. " "one porridge and one rice is hard-won; half silk and half wisp, it is difficult to keep thinking about material resources." Thrift has always been a traditional virtue of the Chinese nation. Recently, with the concept of "saving glorious, shameful waste" more and more deeply rooted in the hearts of the people, the "CD-ROM action" advocating eating, drinking and taking away food on a plate is rising all over the country. Data show that every year, about 1.3 billion tons of food is consumed and wasted in the world, and at least 820 million of the world's 7.633 billion people face hunger, which is equivalent to one in nine people in the world. Saving food is an act of cherishing life. Every grain is obtained by the farmer's uncle's hard work and sweat, and it is the result of hard work. We should respect the fruits of the farmers' uncle's work, cherish every grain, and should not waste it. We should remember that a little makes a national treasure. Save food, start with me.本回答被网友采纳
As we know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change and environmental degradation. Besides, lots of farmland has been lost due to the rapid development of industry and urbanization.
Now, because of global warming and climate anomalies, some kinds of food crops don’t have a splendid harvest, with food lacking and food prices rising. Thus, many of the poor due to soaring food prices can not afford to buy food, hungry to lead a miserable life.
There are a number of possible solutions to the problem, but none of them is easy. In the first place, people can buy advanced agricultural machinery and modernize their farming methods and develop more land. In the second place, when eating in a restaurant, we should order properly and take it home when we can't eat it. Last but not least, develop the habit of not being picky or partial eaters, which can not only nourish our body, but also avoid the hidden danger of waste.
“Who knows, every grain is hard”. To love and save grain is to respect the farmer’s labor. We should not only start from ourselves, but also drive people around us to cherish and save food.(272字)
