there are a number of possible solutions to the problem, but none of them is easy. firstly, governments could discourage people from having large families. why not have just one child?

secondly, farming methods in those countries are very simple and often inefficient. if the people bought new agricultural machinery, modernized their farming methods and developed more land, they might soon produce enough food for their needs.

thirdly, many countries have natural resources such as oil, wood or iron. these could be exported so that food could be imported.

all of these possible solutions simplify the problem. but they show that, if people mean to solve the problems of increasing population and food shortages, there are ways of doing it.

节约能源作文篇2

on the grain composition

在我上一年级的时候，我非常不注意节约粮食。我每天吃饭都剩下许多白花花的米饭在桌子上，在碗里。

when the first grade in me, i do not pay attention to save food. every day i eat all of the remaining many shining white steamed rice on the table, in a bowl.

过不了几天，我剩下的米饭居然差不多有一碗那么多。妈妈看见我这样浪费粮食，决定在星期天带我去田野里走一走，看一看，我高兴得一蹦三尺高。

after a few days, i left a bowl of steamed rice was about so much. my mother saw me such a waste of food, decided to take me to the fields to go on sunday, look, i'm happy i jumped three feet high.

到了星期天，我正要去拉车去田野时，妈妈说：“宝宝，车子坏了，我们只好走着去了。”一路上，猛烈的阳光像一团大火一样，让我感到非常的闷热，豆大的汗珠不断地从额头上渗出来。

on sunday, i'm going to pull the car to go to the fields, mother said: "baby, the car broke down, so we had to walk." along the way, the sun like a ball of fire, let me feel very hot, bean big sweat constantly seeping from the forehead.

田野一片绿色，就像是一块一块绿色的大毯子铺在那里。在这绿色的毯子上，有着许多人在忙碌地干着农活，有的在耙田，有的在挑秧苗，有的……你瞧，那边一个三十多岁的农民伯伯正在抛秧，他从一块奇特的板子上拿出翠绿色的秧苗，撒到田中，让它们自己成长。他每抛撒一把秧苗，手臂上的汗珠都随着秧苗飞洒向田中。此外，还有一个农民婆婆在除草，婆婆轻轻地弯下腰，用那洁净的双手去接触那肮脏的杂草和污泥，虽然杂草除去了，却脏了自己洁净的双手。火似的太阳照射在每个农民的后背上，汗珠湿透了他们每一个人的衣服，每个农民从田里走出来，都是一身污泥一身臭汗。

the fields are green, like a piece of green blanket shop where. in the green carpet, there are many people doing farm work in the busy, some in the harrowing, some in the picking seedling, some...... you see, there a thirtysomething farmer uncle is throwing, he took out a green seedlings from a special board, and to tanaka, let them grow. he threw a seedling, arm sweat with the seedling fly over tanaka. in addition, there is a peasant woman in weeding, mother-in-law gently bent, with the clean hands to touch the dirty weed and sludge, although the weeds, but dirty their hands clean. fire like a sun in each farmer back, sweat soaked their clothes, each farmers out of the fields, is a sludge bromidrosis.

忽然，我看到了我六十岁的外婆也在地里干活，她弯下腰大概只有五六分钟又站起来伸伸腰，并不断地用手捶打着自己地腰。满头的汗珠都来不及擦，正一滴一滴地落在田里。这时。我不禁想起了一首诗：“锄禾日当午，汗滴禾下土。谁知盘中餐。粒粒皆辛苦。”

suddenly, i saw my sixty year old grandmother in the fields, she bent down only about five or six minutes again stand up and stretch, and constantly with the hand beat his waist. the sweat haired wipe all too late, was dripping down in the field. at this time. i can not help but think of a poem: "hoe wo day when, sweat wo soil. who knows the food. a journey."

回到家后，我想了又想，觉得自己以前这样浪费粮食真是太不应该了，我下决心要好好珍惜来之不易的每一粒粮食。

译文：

树

树在我们的.生命中非常重要。它们是地球上的最大、最老的生物。许多东西来自树，举例来说，在你的铅笔中的木头和在你的笔记本的纸张。树能对抗污染，他们能冷却而且清理空气。树与树之间也能与彼此沟通，使它们自己免于昆虫的攻击。

但是现在树正处于危险的环境之中。人们每年不断地砍伐和烧毁它们。树是我们的朋友。让我们尽全力种植更多的树而且保护他们。

how to save electricity?

electricity is very important in our daily life ,we use it to do all kinds of things ,however ,electricity is getting less and less ,we must save it .

first ,don’t turn on too many light at one time .second ,at home ,don’t open fridges too often .third ,remember to turn off all the lights when go out .finally ,we should use air conditioners as little as possible.

let’s do our best to save electricity .

译文：

该如何节约电?

电在我们的日常生活非常重要，我们用它做各种的事情，但现在电变得越来越少，我们一定节约它。

首先，不要同一时间打开太多灯。其次，在家，不要经常开启电冰箱。第三，记得去关掉所有的光当你不需要用它时。最后，我们应该尽可能少使用空调。

让我们尽全力节约电。

节约能源作文篇4

一个夏季的夜晚，我正准备上床睡觉，耳边陡然间传来妈妈的声音:“你怎么又不关灯?人走到哪灯就亮到哪，就不能随手关上吗?”哎，最近不知怎么了，竟然养成了“人在灯亮，人走灯仍亮”的习惯，经常是亮了一整晚的的灯，直到第二天早上才发现。就这样，在不知不觉中，一度电悄悄的溜走了。如果每天都像这样浪费掉一度电，那么一年过后就是浪费掉了365度电，365度电，足够看3650个小时的电视，也是贫困山村里人们整整3个月的用电量!山区的村民有时用电都是一种奢侈，可在我们手中，一度度的电，竟然就这样流失了。

生活中，我们经常能看见这样的情景：一群人走在街上，一边抱怨垃圾太多，到处都是，一边把零食袋子随手一扔，头也不回地走开。或是有意或是无意，人们总是看不见眼前触手可及的垃圾桶，任由垃圾在自己手中划过一条弧线，掉落在地上。就是这看似随意的动作，让我们赖以生存的家园变的脏乱不堪。

地球母亲供给我们充足的氧气、水分和食物，她关心着我们，爱着我们，可我们都做了些什么?工厂里的废气和污水随意排放，一片片森林遭到乱砍乱伐，城市里的垃圾散发着臭气……

现在，环境形势十分严峻。环境保护对我们来说并不是一个新问题，政府也早已提出了明确的治理目标，可一直以来都没有人去实践。我们完全可以从小事做起，从我做起。顾炎武曾经说过，天下兴亡，匹夫有责。而保护环境是我们的天职，保护环境与维护生态平衡的历史重任将落在我们新一代的肩上。同学们，当看到未关的水龙头在滴水时，你是不是能够随手关上呢?当电池用完后，你能否分类收藏处理而不随手扔掉呢?当购物时你能否自觉不使用塑料袋呢?是否能坚持“人在灯亮，人走灯灭”呢?

节约能源作文篇5

enviroment the environment means surroundings in which people, animals and plants develop and exist. ecology is a branch of biology which investigate relationships between living beings and their environment the most serious ecological problems of today are the pollution of air, water and soil, the destruction of ecosystem, disappearance of many species of animals and plants, the weather changes, acid rains, the warming up of the earth surface, the destruction of tropical rain forests and the breaking of the ozone layer.

these damages are caused by the man himself and his technical progress.pollution: we need air to breathe, water to drink and food to eat, but there is a growing number of people in the earth so that we have to share these everything with more people. the growing number of cars contribute much to the air pollution. factories produce a large amount of carbon dioxide, lead poisons etc. which get into the air. some of them in combination with water make sulfuric acid in the clouds, it later falls as acid rain which kills trees and make soil infertile.

factories also pollute rivers because they put there their chemical waste. also farmers pollute the soil using a lot of pesticides and fertilizers. this pollution can also poison groundwater. i think that the best way how to reduce pollution is reducing, reusing and recycling.greenhouse effect: in the last 100yars the earthsurface has warmed up by more than half a degree, this change could cause rising the sea levels by up to one and half meters by the year 20xx.

the greenhouse effect is caused by polluted atmosphere which was polluted by carbon dioxide from fossil fuels and chlorofluorocarbons.the best protection is to stop producing these gases and destroying rain forests. it is worth replacing old power plants with nuclear power which reduce the damage. also nuclear power has its disadvantages, in this case there a e alternative sources of energy : hydropower, solar power, geothermal etc.ozone hole: the ozone gap is thinning at a rapid speed.

it is a layer which protect us from dangerous uv rays, these could damage the life on the eart.

another round of energy crisis is knocking at the door. in 2004, world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly.

as for china, it was reported that many traditional mineral cities in northeastern china had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.

if they were to be exhausted before we could find sufficient reproductive resources to replace them with, we’d have to live in entire blackout again like our ancestors have done thousands of years ago. that’s of course not what anyone would want to see.

due to technical limitations, people still have to utilize these resources now.

as a result, we must economize them most cleverly. new techniques should be developed and applied to reduce energy cost in industry and daily life. alternative energy should be employed wherever possible. eradicate any practice that wastes energy.

humans have overcome so many crises in history, and we’re sure to win this time also.

新一轮的能源危机是敲门。2004年,全球石油消费达到了一个新的记录,导致了在国际市场上石油价格的飙升令人惊讶。

至于中国,据报道,许多传统的矿物在中国东北城市陷入困境,他们的经济崩溃和工人失业,只是因为煤炭被开采出来。

化石能源资源,包括煤炭、石油和天然气,不像阳光,水力和风力发电产生的一致。他们不是几乎在人类历史上繁殖。一旦食用,它们一去不复返了。

如果他们筋疲力尽之前我们能找到足够的生殖资源来替代它们,我们必须生活在整个停电又像我们的祖先几千年前。这当然不是任何人想要看到的东西。

由于技术的限制,人们现在仍然需要利用这些资源。

因此,我们必须节约他们最聪明的。应该开发和应用新技术降低能源成本在工业和日常生活。应尽可能使用替代能源。消除任何浪费能源的实践。

人类历史上已经克服了很多危机,我们这次也一定会赢得。

save the energy resources

another round of energy crisis is knocking at the door. in 20xx, world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly. as for china, it was reported that many traditional mineral cities in northeastern china had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.

fossil energy resources, including coal, oil and gas, are unlike sunlight, water power and wind power which are generated consistently. they’re not practically reproductive during human history. once consumed, they’re gone forever. if they were to be exhausted before we could find sufficient reproductive resources to replace them with, we’d have to live in entire blackout again like our ancestors have done thousands of years ago. that’s of course not what anyone would want to see.

due to technical limitations, people still have to utilize these resources now.

with the develope of society,many people begin to care about saving energy.i think saving energy is everyones duty.so we should do well our responsibility.for instance,we need remeber to shut off the lamp when we leave a room without anyone else and shut off the tap when stop to use it to save water.sometimes we can take our bay to the supermarket to buy something.it can save resources.finally,the most basica is we cant throw litter on the ground anyway.we have one earth ,she is our only home.if everyone do his best to protect her,she will be more beautiful.
