1)Quite a few teminally ill patients would often like their doctors to administer lethal drugs to them to be relieved of suffering;there are also some of their families who would prefer that doctors withdraw any life-prolonging treatment since there is no hope of effecting an ultimate cure.this problem has lately boiled into a fierce public debate in some European countries.
2)Those who are opposed to Euthanasia believe that it is no different from murder and that it is unethical,while the pro-euthanasists contend that since the incurably ill consider their existence more of a torrent and suffering,why not let them end their lives in a decent and human way?we ought to respect the patients’final decision.
3)The fear that “mercy killing”may be abused or used unnecessary is not groundless.But with effective measures rigorously taken by the government and the departments concerned,and under tightly controlled conditions in hospitals,this problem would most probably be resolved in the end.

1)The plunge we take is no different from the gamble we are taking against chance,against destiny,and in the course of it we may realize ourselfves as an added bonus.And as a consequence we would be either bled white or finally make a carrer after painstaking efforts,or in rare cases,be continuously blessed with an unhindered advance,and we would take gerat pride in our obtained success.
2)If a man makes gambling an obsession,he will not only lose his property gained through years of toil,he will also lose his dignity and conscience.Therefore it is advisable that they beat a hasty retreat from such an indulgence and be away from the sea of troubles.
3)On the bright side of the coin,we win in the struggle against destiny,and the odds are in our favor,then gambling is no longer a toxic drug,rather it is one against boredom and apathy,and may well preserve our good temper,patience and optimism,which will do us a world of favor.

1.The role of laughter is more complex than people have imagined. People laugh for a variety of reasons.People laugh not only when they feel good, but in response to mundane statements and in uncomfortable situations as well.For example, when people are surprised at funny-looking things, their natural reaction is laughter. When they feel awkward about something or when they are at a loss what to do, they can’t help laughing. Even in a threatening situation, laughter may serve as a way of calming down the tense atmosphere.
2.Why do we laugh? A convincing explanation waits for more confirmation. But people all over the world are convinced that it is pretty good to laugh.Laughter enables people to keep healthy physically and mentally and laughter functions as some kind of social lubricant for people’s communication because studies have shown that people are more likely to laugh in social settings than when they are alone, and it can break down barriers and forge a connection with each other.

1.Languages are vehicles of value systems and of cultural expressions and they constitute a determining factor in the identity of groups and individuals. Yet, it is reckoned that more than fifty per cent of the world’s 6000 languages are on the verge of becoming extinct. And, as a matter of fact, one language disappears on average every two weeks. Many factors contribute to language extinction. But the English language prevalent worldwide is certainly to blame and its hegemony is worrisome.
2.There is overwhelming/compelling evidence that the United States is undoubtedly a global leader in many ways. While exporting its high-tech products and commercial artifacts, the United States is subtly imposing American values on the world. Therefore, some people turn their noses up at globalization ,fearing that it is in fact equivalent to Americanization. Such fears are not over-blown.

1.At the global level, the environmental movement has already been under way for decades and the public awareness of environmental protection has been correspondingly enhanced. In spite of this, the health of Mother Earth is still deteriorating at an unprecedented rate. Many people can’t help wondering how long it will take for human beings to turn things around.
2.Without abiding by the basic ecological principles, some underdeveloped countries have achieved rapid economic growth in the past decades but at the expense of the environment. To make matters worse, they have failed to put effective brakes on the overgrowth of their populations. As a result, environmental degradation and population expansion are driving an ever-increasing number of people into poverty.
