In some countries,many more people are choosing to live alone nowadays than in the past.Do you think this is a positive or negative development?
In recent years it has become far more normal for people to live alone,particularly in large cities in the developed world(句型：In recent years it has become far more normal for…to do…,particularly……).In my opinion,this trend could have both positive and negative consequences in equal measure（观点:积极消极参半-in equal measure）.
The rise in one-person households（词汇）can be seen as positive for both personal（角度1）and broader economic（角度2）reasons.（非常好的主题句，给出了优点的两个角度，可借鉴）On an individual level（引出第 一个角度）,people who choose to live alone may become more independent and self-reliant（词汇）than those who live with family members.（观点句－比较级）A young adult who lives alone,for example,（举例做插入放中间）will need to learn to cook,clean,pay bills and manage his or her budget,all of which are valuable life skills;an increase in the number of such individuals can certainly be seen as a positive development.From an economic perspective（引出第二个角度）,the trend towards living alone（the trend toward doing something-词汇）will result in greater demand for housing.This is likely to benefit the construction industry,estate agents（给出具体例子）and a whole host of other companies that rely on homeowners to buy their products or services.
However,the personal and economic arguments given above can be considered from the opposite angle（句型：However,….can be considered from the opposite angle）.Firstly,rather than(反角度1）the positive feeling of increased independence,people who live alone may experience feelings of loneliness,isolation and worry.They miss out on the emotional support and daily conversation that family or flatmates can provide,and they must bear the weight of(词汇)all household bills and responsibilities;in this sense,perhaps the trend towards living alone is a negative one.Secondly,from the financial point of view（反角度2）,a rise in demand for housing is likely to push up property（词汇：财产）prices and rents.While this may benefit some businesses（关联上一段）,the general population,including those who live alone,will be faced with rising living costs.
In conclusion,the increase in one-person households will have both beneficial and detrimental effects on individuals and on the economy.
