Though it seems that it is hard to accurately predict   【小题1】future cars may be like, they will be   【小题2】 (potential) different in many aspects from traditional ones.

On the whole, shaped like bullets, future cars have the capacity   【小题3】 (drive) at much higher speed and they will be more energy efficient and affordable, which are   【小题4】 the horizon. More importantly, the cars will not only drive   【小题5】 (automatic) but can also be transformed into smaller boxes instantly we park, 【小题6】 (make) it possible to solve the problem of limited places to park.

Sooner or later, future cars will be bound   【小题7】 (offer) us more secure and comfortable driving experiences.

What will our cities be like in 2050? How much will artificial intelligence advance? Some scientists【小题1】 (make) different predictions recently.

Joel E.Cohen from the The Rockfeller University says【小题2】is likely that by 2050 the majority of the people in the world will live in urban areas, and will have a【小题3】(significant) higher average age than people today. Cities will be【小题4】only realistic solution to housing a population that is expected to expand【小题5】9.7 billion by 2050.

And the technology will keep【小题6】(advance) rapidly. According to Bill Michell, the late director of MIT Media Lab’s Smart Cities research group, cities of the future won’t look like “some sort of science-fiction fantasy” or “Star Trek” ,but virtual reality will change【小题7】we live. Self-driving cars will make the roads【小题8】(secure), driving more efficient, and provide faster transport.

Charles Ebinger at the Brookings Institution thinks that by 2050 we will also have a so-called “smart grid” where all of our【小题9】 (appliance) are linked directly to energy distribution(分布) systems,【小题10】(allow) for real-time pricing based on supply and demand. Such a technology would greatly benefit most people and reduced the consumption(消耗) of fossil fuel energy.

Robots have been widely used in our daily life. They can be 【小题1】 (see) in many factories today and have gone to such far places as 【小题2】 moon. Some robots can” see" 【小题3】( clear). For they use TV cameras as their 【小题4】 (eye), Many robots have computer brains, Now they have even come into   【小题5】   (we) homes and work as   【小题6】 (help) at home , Not only can they do simple jobs for us ,such as 【小题7】   (put) things into boxes , but also they can look【小题8】 babies Unlike human beings   【小题9】 needy sleep, robots can work 24 hours a day. In the future, with the aid of robots, our life will become much 【小题10】 (easy) than before.
