animals were friends or foes of humanity at different times of the human history. in modern times, experiments upon animals have long been a breeding ground for spirited debate. some animal activists argue that we should ban animal experiments altogether because subjecting animals to experimentation is unjustifiable on moral grounds. yet some other people contend that the advancement of science necessitates animal testing. personally, i believe both their views have merit and demerit.

granted, empirical evidence suggests that many animal experiments are performed callously without any heed to the discomfort or pain that laboratory mammals endure. first and foremost, improper confinement of test animals such as locking them up in cramped cages or poor veterinary is inhumane .it can gravely disrupt natural biological functions of the test animal. further, the effects of vaccination and vivisection conducted on live rodents, primates and other lab mammals can be gruesome and chilling. they may, in some cases, even constitute sheer torture of live animals.

however, from a more pragmatic perspective, evidence is mounting that animal experimentation is still largely a necessary evil and there is no practical alternative for it at this point. in the first place, it is manifest that drug experimentation on live mammals is far more effectual than experimentation on bacteria or on other lower species in testing drug safety. drugs that have severe potential side effects on homo sapiens must be tested by pharmaceutical companies on live mammals first to ascertain their toxicity. in the second place, in space research, live animals are still the only viable alternative to humans in testing living creature reaction to outer-space experience on a flight not considered to be sufficiently safe for human astronauts. lastly, lab research about the behavioral tendencies of chimpanzees, gorillas, orangutans and other members of the primate group is also necessary. it produces valuable outcomes consistently advancing anthropological and genetic studies.

to conclude, i concede that experiments upon animals may induce suffering to the test animals. however, i am convinced that there are no feasible alternatives to this methodology at the current stage of scientific development. on balance , i think that we should allow animals testing to be continued but at the same time use techniques such as analgesic, anesthetic and tranquilizing drugs to minimize the pain inflicted upon the test animal and augment the general welfare of these animals.

雅思作文范文篇4

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.

wild animals have no place in the 21st century. some people think that preventing these wild animals from dying out is a waste of resource. to what extent do you agree or disagree with this opinion.

biological diversity has never been so threatened as it is today as a result of the process of human civilization. the various forms of pressure created by human activity have destroyed natural balance, led to the deterioration of natural habitats, genetic erosion and the rarity, even disappearance, of a number of plant and animal species.

as the pace of civilization accelerates, more people, taking more space, needing to use more natural resources, engaging in ever-growing consumption, impose severe deterioration on the habitat of animals. an increasing number of people come to realize that the disappearance of animals will result in serious threat to the equilibrium of ecosystem. simply put, the extinction of hawks, a rat-eating bird seen in many regions, will result in the rapid propagation of rats. and rats, further, will destroy the prairies and threaten the other animals like gazelles, zebras and others, who live on grass and green lands. the coexistence of animals and human beings creates perfect harmony and brings about the vividness to our planet.

it is hard to imagine what our world would be like without animals. sociologists also point out that the disappearance of animals can cause social and economic problems. animal trade, as a supporting sector to the world economy, was very active before. however, the situation is beyond control since animal trade is very profitable and alluring. many species cannot escape the adversity of being killed.

certainly, our diet cannot be without meat. there are living stocks, which can provide us with sufficient and nutritious produce. therefore, we need not to resort to wild animals, especially the endangered ones. to protect animals is to protect our living environment. every individual should join efforts to keep the diversity of animals.

people in all modern societies use drugs, but today's youth are expertimenting with both legal and illegal drugs, and at an increasingly early age. some sociologists claim that parents and other members of society often set a bad example.

discuss the causes and some effects of widespread drug use by young people in modern day society. make any recommendations you feel are necessary to help fight youth drug abuse.

model answer:

youth drug abuse is a serious problem nowadays in many cultures. not only is illegal drug use on the rise, but children as young as 10 years old are experimenting with alcohol and tobacco. the reasons for this behaviour are unclear, but certain sociologists blame the examples set by their elders.

parents who drink and smoke to excess are, in effect, telling their children that it is acceptable to abuse their bodies with drugs. consequently, children may have a similar view towards illegal drugs, even if their parents are against their use. in addition, drug use shown on television and in films can only confuse children who are also taught at school that drug abuse is wrong.

the pressure on young people to perform well at school in order to compete for jobs is a possible cause of the problem. many believe they cannot live up to their parents' expectations, and feel a sense of hopelessness. also, the widespread availability of drugs means teenagers are faced with the temptation to experiment. drugs are used as a means of expressing dissatisfaction with the pressures they face in society.

the effects of drug abuse are well known. many young people's talents are wasted, and addiction to hard drugs can cost a user his or her life. furthermore, those who drink and drive may be involved in fatal road accidents. the cost to society is great, and enormous amounts of money are spent on convicting drug dealers and on education programmes.

to conclude, i recommend that the only sensible way to solve this problem is to educate young people about the dangers of drug use, and to take steps to reduce the pressure of competition placed upon them.

some people think that advertising may have positive economic effects, while others think that advertising has social effects because individuals are not satisfied with who they are. they discuss two views and give your opinion + 9 brainstorming. when it comes to the effect of advertising, some people think that advertising can promote, but others think that on the one hand, advertising may produce some social effects, such as psychology imbalance, advertising can stimulate consumers to buy more goods and promote economic growth.

therefore, people realize that the purpose of advertising is to introduce the characteristics and characteristics of products to consumers through television, radio, internet and other channels. when consumers see some new items in advertisements, some of them will decide to buy these new products to meet their needs. such purchase behavior will help manufacturers to obtain more profits and expand their industry on the other hand, advertising does have some negative social effects.

at present, many well-known and even luxury brands spend a lot of money on advertising to make them more influential among consumers. however, for the poor, they may not be able to afford any luxury goods they see in advertisements. the fact that some consumers, especially poor consumers, are ignored by these brands can explain why they do not satisfaction.

from my personal point of view, these economic and social effects of advertising exist at the same time. if consumers only regard advertising as a source of information for new products, if consumers are envious of the numbers in advertisements and complain about their low quality of life, economic development will be promoted. in order to avoid such negative consequences, the government needs to filter out some "no" in advertisements appropriate content, for example, some advertisements suggest that life can be boring and boring if one does not pay for recommended items.

therefore, the government needs to better regulate advertising to reduce this negative impact.

the pie charts compare visitorssquo; responses to a survey about customer service at the parkway hotel in 2005 and in 2010.

it is clear that overall customer satisfaction increased considerably from 2005 to 2010. while most hotel guests rated customer service as satisfactory or poor in 2005, a clear majority described the hotelsquo;s service as good or excellent in 2010.

looking at the positive responses first, in 2005 only 5% of the hotelsquo;s visitors rated its customer service as excellent, but this figure rose to 28% in 2010. furthermore, while only 14% of guests described customer service in the hotel as good in 2005, almost three times as many people gave this rating five years later.

with regard to negative feedback, the proportion of guests who considered the hotelsquo;s customer service to be poor fell from 21% in 2005 to only 12% in 2010. similarly, the proportion of people who thought customer service was very poor dropped from 15% to only 4% over the 5-year period. finally, a fall in the number of squo;satisfactorysquo; ratings in 2010 reflects the fact that more people gave positive responses to the survey in that year.
