1. Whafs the differences between outdoor sports and indoor sports?
There are many differences between outdoor sports and indoor sports; each of which have their own advantages and disadvantages. Outdoor sports have many advantages such as being able to play in the sun and fresh air on beautiful days. Furthermore, outdoor sports are often less limited by space than indoor sports which must be constricted (受限制的)to the size of a building or room. However, in contrast to this, indoor sports have many benefits that outdoor sports do not. For example, outdoor sports are not a lot of fun to play in bad weather but indoor sports are never affected by the weather.
2. What kinds of water sports are popular nowadays?
There are all sorts of different watersports which are popular nowadays. Watersports are often considered one of the greatest forms of exercise as swimming exercises (动词,锻炼)almost all of the muscle groups (肌肉群)in one^ body. Therefore, there are many people who use watersports as a means of staying in shape. However, there is another form of water sport that are becoming very popular nowadays. There are many extreme water sports which people like to play to experience a thrill and an * rush (肾上腺素).There are so many fast paced water sports such as water skiing, surfing and diving. All of these sports push people to extreme limits but can be very dangerous.
3. Why should we develop water transport?
There are both arguments for and arguments against why we should develop water transport. Some people believe that we should develop water transport because it may be far more ecologically sustainable (生态的可持续发展)than the air transport we are currently reliant (依靠)on as a civilisation. Water transport emits (发出、释放)far less greenhouse gasses than air transport does so it is a far more sustainable form of transport. However, the current issue with it is that water transport is a very slow form of transport compared to flying. Therefore, it would be good if we could develop water transport in the hopes of creating a fast water transport system which is still ecologically friendly. However, there are mixed opinions on this topic. For example, people living in areas such as the Mediterranean (地中海)are very supportive of developing water transport because they live in an area where many countries are connected by water so this would be an effective form of transport. But in contrast, many countries, such as China for example, have huge areas of land in which water transport is not effective. Therefore, it seems like a bad area to invest development when there are places where water transport is impossible.
4.Do you think it is necessary for everyone to learn to swim?
Personally, I believe swimming is a very important skill to learn. Swimming is an excellent form of exercise and swimming also offers many social opportunities when one is on holiday. Therefore, there are many personal advantages to knowing how to swim. Yet the most important reason is that knowing how to swim can be the difference between life and death. Accidents are very common in life and you never know when you may accidentally fall into deep water with no one around to help you. If you do not know how to swim then there may be very little hope that you survive.
