the world is experiencing a dramatic increase in population, this is causing problems not only for poor, undeveloped countries, but also for industrialised and developing nations.

describe some of the problems that overpopulation causes, and suggest at least one possible solution.

model answer:

in most countries of the world the population is increasing alarmingly. this is especially true in poor, undeveloped countries. overpopulation causes a considerable number of problems.

in poor countries it is difficult to provide enough food to feed even the present number of people. in addition, education to limit the number of children per family is not always successful. poorer countries usually have a lot of unemployment too, and an increase in population simply makes the situation worse. the environment also suffers when there are too many people living on the land.

in rich, industrialised and developing countries it is very difficult for governments to provide effective public services in overcrowded cities. moreover, there is usually a great deal more crime, which is often due to high rates of unemployment. further large increases in population only cause more overcrowding, unemployment and crime.

there are two main solutions to the overpopulation problem. firstly, every woman who is pregnant, but who does not want to give birth, should be allowed by law to have an abortion. secondly, governments must educate people to limit the size of the family. in china, couples are penalised financially if they have more than one child. this may seem cruel, but the "one-child policy" is beginning to have an effect in the world's most populous nation. eventually, similar policies might also be necessary in other crowded nations such as india, for example.

to sum up, if the population explosion continues, many more people will die of starvation in poor countries, and life in the cities, even in affluent nations, will become increasingly difficult.

task：some people argue that too much attention and too many resources are given to the protection of wild animals and birds.to what extent do you agree or disagree?

sample answer：

in recent years, animal protection has become an issue of concern. people take different attitudes towards the increasing attention and expenditure on wildlife conservation. some people suggest that the spending should be redirected to helping other fields in society. i agree with the view that the investment in wildlife protection is not worthwhile.

animals, as a key component of the whole food chain, have a profound impact on the sustainability of an ecosystem. as we known, every kind of animals plays an important role in natural balance. for instance, the demise of any species will lead to the growth or decline of other species. in some extreme cases, some species may at the verge of extinction such as dodo bird. if people did not take actions to protect wildlife as soon as possible, we humans would be affected in the end.

however, there are more issues that we need to focus in our society rather than protecting animals. in current social context, the primary task is still to improve living standards since there are many people living under the poverty line. only when people are in a good living condition, can they pay attention to other social problems. besides, technology and education are another two aspects of governments to concern. these two industries accelerate the development of society, which will provide a better protection for wildlife in turn.

in conclusion, although the animal is a significant part of ecosystem, it is better for governments to invest more finance and resources in other social problems.

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。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。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。
