　　劣势一：

　　中心句(笼统说明段落大意)： The distance may widen the gap and loosen the bond. 根据中心句展开(说明白具体情况)： Although the gap between the parents and children is inevitable, being apart widens the gap, 讲“为什么”，是论证的关键： because the distance deprives them of the chance to share thoughts and feelings and to have any mutual understanding, even making them strangers. The separation alsostretches the bond. As the bond is stretched and becomes thin, it may eventually be broken. For example, it is not uncommon that the elderly living in the nursing homes are seldom visited by their children. Those people live alone and some of them even die lonely.

　　劣势二：

　　中心句(笼统说明段落大意)： Living with other old-aged people may accelerate their aging. 根据中心句展开(说明白具体情况)： Although getting old is the natural course, which cannot be reversed, being with people of the same old age makes the process faster. 讲“为什么”，是论证的关键：Hardly can a couple of seniors look at life or the world afresh; instead, they are more likely to agree with each other on their outdated views on the surroundings and sigh for the retirement and being useless, attributed to the old age. The lack of sparks or their pessimism makes them mentally older than their biological age.
