most people have dreams of one day becoming rich. but does the average person have the ability to make a lot of money？ think about this question. then write about 250 words describing your thoughts.

when lack of money prevents us from having something we want very much， it is tempting to dream of being rich. it is hard to keep in mind that americans are already wealthy compared with people in many other parts of the world. our modern conveniences would have been the envy of kings in times past. just the same， most people would like a larger. whether most people are capable of making a lot of money is another question.

people in average circumstances can often get ahead through education， hard work， and careful money management. but getting ahead is not the same as actually becoming rich.

only a small percentage of americans could be called truly wealthy. some people joined this group from ordinary beginnings. usually they have done it by carefully riding some major development in the economy on its way up. in the past， great fortunes have been made in oil， steel， and railroads. recently， some people have made millions in computers and real estate.

usually， though， it takes money to make money. big investors often start rich and then get richer. most of us cannot strike oil or start the next new technical breakthrough. most people are not born into wealthy families， either. in america it certainly is possible to become more prosperous. but unless someone wins the lottery， real wealth is not very likely to come along.

the charts compare the sources of electricity in australia and france in the years 1980 and 2000. during these years electricity production almost doubled, rising from 100 units to 170 in australia, and from 90 to 180 units in france.

in 1980 australia used coal as the main electricity source (50 units) and the remainder was produced from natural gas, hydro power (each producing 20 units) and oil (which produced only 10 units). by 2000, coal had become the fuel for more than 75% of electricity produced and only hydro power continued to be another significant source supplying approximately 20%.

in contrast, france used coal as a source for only 25 units of electricity in 1980, which was matched by natural gas. the remaining 40 units were produced largely from oil and nuclear power, with hydro power contributing only 5 units. but by 2000 nuclear power, which was not used at all in australia, had developed into the main source, producing almost 75% of electricity, at 126 units, while coal and oil together produced only 50 units. other sources were no longer significant.

overall, it is clear that by 2000 these two countries relied on different principal fuel sources: australia relied on coal and france on nuclear power.

human beings have only one earth, it is the natural resources of human survival, people want to live a happy life, we must consciously protect the natural environment, love the earth.

however, in recent years, the earth's environment has become increasingly bad: global warming, hurricanes, heavy rain and other severe weather, "sars", avian flu and other infectious diseases occur, to human life and the work poses a serious threat and a lot of inconvenience. these are the result of people constantly "hurting" the earth. large tracts of forest are cut down, green green mountains are excavated, beautiful grassland into desert, clear river into a turbid flow. the forest is less, the grassland bald, grassland shortage, dark water, so that people living environment deteriorated, breathing the air worse, the living environment by many harmful things "encroachment", the virus took the opportunity to get into the people in the body, we humans will suffer from some terrible disease.

a few days ago, i saw in the newspaper such a comic: a person sitting on the treetops, is cutting his sitting tree branches. "well, it's funny." some people might think so. do not you think about it, is it just funny comic? is it not in the irony of us? do not you realize that it warns us that mankind, while destroying the environment, is unknowingly hurting himself.

when you walk in the street, if you want to spit, what would you do? if you choose to spit on the ground, then you think no, you are harm yourself? a sputum contains a lot of bacteria, when the sun will be breeding, infection. similarly, when you cut down a tree, when you dig a piece of grass, when you put the dirt into the river, do not you think it is in the destruction of the environment, "hurt" yourself?

as the saying goes: "predecessors planted trees, descendants shade," the previous people gave us large tracts of forest, green, we left to future generations what is it? is the bare desert, or the dense woods, you must choose is the dense woods. so what hesitation, let us all consciously protect the environment, consciously care for the environment, consciously greening the environment, improve our living environment, create a better future!

from the picture, we can see clearly that our earth is suffering from "lung cancer" caused by environmental pollution. its deteriorating condition is threatening all forms of life, pushing them to the edge of extinction. just as is vividly depicted, continents that used to be covered by green life now turn deadly black.

the damage to the natural environment began as early as the arrival of industrilization. while abundant products are offered to the society, industrialization also brings the side effect of all forms of pollution. moreover, human exploitation of natural resources has caused destruction that is far beyond our imagination.currently the ecosystem is on the verge of collapse, while the population of mankind is still increasing steadily and uncontrollably. more unfortunately, human beings seem addicted to industrial production and material wealth but are hardly aware of the potential dangers.

we must realize that we are neither the master of the earth, nor should we become the slaves of the advanced technology. man and nature are supposed to coexist in great harmony. without changing our negative attitude towards nature, humans will face a fatal destiny. to briefly conclude, economic development should not be achieved at the cost of our earth's "health".

i am from saint-petersburg, russia. i believe that building a large factory near my community has advantages as well as disadvantages. in the following paragraphs i will list basic benefits and losses that will be brought by a new factory.

for several reasons, i think that a new factory will not be a good addition to my neighborhood. first of all, factories often bring pollution. they are prone to contaminating the local air and water. second of all, factories make noise. another important aspect of building a new factory near by is that it will make the local traffic heavy. as a result of this, the amount of traffic congestions will increase, as well as contamination of the air. so, all these obviously will not make one's life happier and healthier in my community.

from the other side, i believe that a new factory will bring some advantages to my community. first of all, it will bring new job opportunities. many specialists will be required to work there. second of all, i think many local community facilities will have to be renovated to obtain reliable supply of water and electricity. so, some old pipes may be changed. another important benefit of this is that the local roads in order to manage the increasing traffic will be rebuilt and widened.

however, i do not think that listed above benefits are worth all these troubles including water contamination and the constant pollution of air. from my point of view all factories must be built far from the people communities because they can be really harmful for people's health.

我从圣彼得堡，俄罗斯。我相信在我的社区附近建一个大工厂既有利也有弊。在下面的段落中，我将列出一个新工厂带来的基本利益和损失。

由于种种原因，我认为新工厂不会成为我邻居的好邻居。首先，工厂经常带来污染雅思大作文范文及翻译雅思大作文范文及翻译。他们容易污染当地的空气和水。其次，工厂制造噪音。附近新建一个工厂的另一个重要方面是它会使当地的交通拥挤。因此，交通拥堵的数量会增加，以及空气污染。所以，在我的社区里，这些显然不会让一个人的生活更幸福更健康。

从另一方面来说，我相信新工厂会给我的社区带来一些好处。首先，它会带来新的就业机会。许多专家将被要求在那里工作

第二，我认为很多地方的社区设施必须翻新，以获得可靠的水电供应雅思大作文范文及翻译雅思(ielts)。因此，一些旧的管道可能会改变。另一个重要的好处是，当地的道路，以管理日益增加的交通将重建和扩大。

不过，我不认为上面列出的好处是值得所有这些麻烦，包括水污染和空气的不断污染。在我看来，所有的工厂必须建在远离人民的社区，因为它们可能对人们的健康有害。
