Câu hỏi: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.
Super skyscrapers, underwater cities, 3D-printed homes, and holidays in space will all be a reality in 100 years' time, according to the SmartThings Future Living Report. The report presented findings from a survey conducted by Samsung's SmartThings company with a group of experts on space, architecture, and urban planners. Several futurologists and adults of different occupations also took part in the survey.
The experts suggest that in a century's time humans will be able to live in 'Earth-scrapers', which will go up to 25 storeys underground. They also believe that 'bubble cities' will be created underwater making the depths habitable for humans. They say the way we live, work and play will be totally different to how we do these things today. The authors of the report say that 25 years ago, people could not imagine how the Internet and smartphones would change our lives. They have revolutionised the way we communicate, learn and do daily things. So, it is understandable that the changes in the next century would be even more unbelievable.
Researchers also questioned 2,000 adults about the predictions they thought were most likely to happen in the future. Respondents predict that in the future, few people will go to an office but will work from home and have virtual work meetings instead. People will have advanced 3D printers that will let us download a design for furniture or a food recipe and then 'print' the sofa, table or pizza at home. There will also be less need for visits to the doctor. We will all have a home health capsule which will tell us what the problem is and give us treatment. We will also go into space for holidays and to get resources that we have used up on Earth. A prediction that was missing was about the popularity of English – whether people would still need to study English or not.
