Ielts 雅思 口语全攻略 Ideas and Examples for ielts speaking Jeremy Chiron

What new scientific developments do you expect to see in the next ten or twenty years?

Well, I expect some progress in the medical field (= in terms of medicine). I hope that scientists will be able to find a cure for cancer and AIDS. I also think that researchers might come up with a new science to prolong our lives on earth. I think we will definitely be able to clone some hearts, and other essential organs, so that it will be possible to get a transplant and continue living. In addition, there will be some major developments in terms of technology and machinery. I am sure that we won't be using petrol as a source of energy for very long. It will soon be replaced by solar or electrical energy. They are also working on a hydrogen motor to make cars more environmentally-friendly (= eco-friendly). On top of this, there will be some major scientific changes in the home. Some people predict we will soon have robots at home to do all of the chores we dislike. Some say it might happen before 2030, but I am a little skeptical (= I have doubts).

3. 
   Do you think that textbooks will be replaced by other media in the future?
   

I think that in the future everyone will have a personal laptop, so more students will read online textbooks. The sales of paper books will decline, but they won't totally be replaced. People realize it is more enjoyable to read on paper, and it is also much better for the eyes. I think that people will soon get tired of some of the technology we find so convenient and cool at the moment.
