8. In your opinion,do cars need any technical innovation today? In what aspects?
Of course they do. They should be improved in the following aspects. To begin with, technical innovation should be adopted in order that cars can emit less exhaust gases, and our environment will be become cleaner. What's more, cars should be improved to consume less oil. It is well known that oil belongs to the category of resources which can't be regenerated, and that the course of some wars is oil,so if energy-sav-ing cars can be produced on a large scale,the world will become peaceful. Besides,the safety of cars is always people's priority. In today's world,human beings are the most productive forces,so great importance should be attached to the lives of people, which explains the importance of safety performance of cars.
9. Looking into the future, what kinds of new transportation methods will scientists develop?
Its hard to tell. But scientists should have the ability to develop any kinds of transportation means imaginable. As far as I'm concerned, I hope there will be such means of transportation as can travel on land,dive into water and fly in the air. I saw this kind of vehicle in the movie series 007.
10. In terms of transportation, what will be the effects that new technology will bring to people and what will be the development tendency in the future?
New technology will definitely make people's travel more convenient,rapid and comfortable. In the future there will be a more modernized transportation network with advanced airplanes in the air,magnetic suspension trains and energy-saving electronic automobiles on land, tubes under ground and submarines in water.
