題目：The effects of longer life expectancy both on aging individual and on society
本文的Assignment 是問題類的措辭。這個題目是說壽命長對個人和社會有什麼影響，其實某種程度上就是問各位年紀大的.人對個人和社會有什麼影響。
思路：
1. 對個人的影響
1) 向外看對年輕人
觀點：壽命變長larger proportion of elders---render the youth disadvantaged in the workplace
論證：It can be observed that young people might be deprived of their opportunities to develop their abilities as more old people could mean that they have more chances to occupy essential social positions。
內部可以配搭實驗法。
A group of researchers in the University of Suzhou conducted a research recently on white-collar workers aging from 25-35 in international companies, whose result revealed that three out five people expressed they could hardly get promoted to managerial posts owing to the large number of senior citizens who held supervisory positions。
2) 向外看對家人
老年人可以活得更久就可以更好地照顧他們的子女甚至是孫兒，對於家庭的幸福和穩定是很有好處的。
觀點：Longer life span could contribute to the happiness and stability of a family。
