Task 2
Atthe present time, the population of some countries includes a relatively largenumber of young adults, compared with the number of older people.
Dothe advantage of this situation outweigh the disadvantage?

Many countries, nowadays, have witnessed a larger proportion of young adults compared to that of older citizens in demographic pattern.Although older people may contribute considerably to society, I would argue that young people play a more important role in social progress.


The large amount of young people means fresh blood to local companies. They are more easily to adapt themselves to the new environment and more readily to accept the new challenges compared to the elderly. For instance, the advent of the Internet has dramatically changed people’ work and life. Young people prone to grasp the computer knowledge quickly and efficiently while elder workers may find difficulty in operating the computer.


What’s more, young workers take up greatershare in workforce, which means the economy of a country can be greatly improved by larger number of young adults. Some industries such as manufacturing sector, needs larger labors to cut the budget so that they could enhance theirproductivity and thus social productivity, whereas many older people cannotbear long-working hours.


On the other hand, the large number of young people may also impose heavy burden on the local government, giving riseto many social problems like the shortage of housing and social instability. In this regard, the government has to allocate large sum of money to address those problems.


All in all, the considerable population ofyoung adults can be an asset to society for they can bring vitality and innovation to local corporates. In addition, they will exert great impact on the economic development of a country as well.

The line graph vividly reveals the change of amount of energy consumed by different types of fuels in America from 1980 with projected consumption to 2030.

The consumption of petrol and oil increased considerably from 35 quadrillion units in 1980 to the expected amount of about 50 q in 2030, whichare the greatest among the eight types of energy. Coal and natural gas enjoys almost the same growing pattern during the 50 years period, with the likely amount of 30 q and 23 q in 2030 respectively. In addition, there are also three types of energy sources, nuclear, solar or wind, whose consumption grew slightly before 2005 and will keep the same amount until 2030. Hydropower, the only type of fuel that dropped to the starting figure in 2010 is expected to level out until 2030.

Overall, the energy consumption by petrol and oil will show a dramatic increase in the coming two decades while renewable energy sources and nuclear energy will stay the same.
