题目：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. In my opinion, this trend could have both positive and negative consequences in equal measure.
The rise in one-person households can be seen as positive for both personal and broader economic reasons. On an individual level, people who choose to live alone may become more independent and self-reliant than those who live with family members. A young adult who lives alone, for example, 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, the trend towards living alone will result in greater demand for housing. This is likely to benefit the construction industry, estate agents 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. Firstly, rather than 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 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, a rise in demand for housing is likely to push up property prices and rents. While this may benefit some businesses, 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.
题目：Some people think that all university students should study whatever they like. Others believe that they should only be allowed to study subjects that will be useful in the future, such as those related to science and technology. Discuss both these views and give your own opinion.
People have different views about how much choice students should have with regard to what they can study at university. While some argue that it would be better for students to be forced into certain key subject areas, I believe that everyone should be able to study the course of their choice.
There are various reasons why people believe that universities should only offer subjects that will be useful in the future. They may assert that university courses like medicine, engineering and information technology are more likely to be beneficial than certain art degrees. From a personal perspective, it can be argued that these courses provide more job opportunities, career progression, better salaries, and therefore an improved quality of life for students who take them. On the societal level, by forcing people to choose particular university subjects, governments can ensure that any knowledge and skill gaps in the economy are covered. Finally, a focus on technology in higher education could lead to new inventions, economic growth, and greater future prosperity.
In spite of these arguments, I believe that university students should be free to choose their preferred areas of study. In my opinion, society will benefit more if our students are passionate about what they are learning. Besides, nobody can really predict which areas of knowledge will be most useful to society in the future, and it may be that employers begin to value creative thinking skills above practical or technical skills. If this were the case, perhaps we would need more students of art, history and philosophy than of science or technology.
In conclusion, although it might seem sensible for universities to focus only on the most useful subjects, I personally prefer the current system in which people have the right to study whatever they like.
