Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they'll improve your city's infrastructure . Lighting Up The Night Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees' swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees' outer LEDs. Thinking Outside The Box As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents' health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition. Waving Hello To Clean Energy Cities that don't receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption , electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs. How do the Netherlands improve the city traffic according to the text? A) By updating the city roadway condition. B) By building walking passages underground. C) By creating suspended roundabouts above roadways. D) By supporting more biking and walking.

Ques:Last week I visited my friend Pete in the new home where he lives with his wife and daughter. Pete used to spend his holidays travelling the world, visiting the pyramids in Egypt or scuba diving in the Caribbean. Nowadays he prefers to spend his holidays and weekends making his house look more beautiful. Like hundreds of thousands of other British people, he has discovered the joy of DIY (Do It Yourself), which means if there are any things that need fixing around the house, he will try to do the job himself. As he showed me the new kitchen he put together by himself and the newly painted walls, I asked Pete where he got his inspiration from. He told me that his favorite source of ideas was a DIY program on TV. This got me thinking about the great popularity of DIY programs in the UK. Each major channel has at least one home or garden improving show and there's even a satellite channel completely about the subject. I guess it is not really surprising that DIY programs are so popular. Two common sayings in Britain- 'an Englishman's home is his castle' and 'there's no place like home'-show how important our houses are to us. With the present economic downturn, many people can't afford to buy a bigger house so they are looking at how they can make their house better without spending a lot of money. DIY is the perfect choice. But be careful! I read a report that said over 230,000 people were injured while doing home improvements in the UK in just one year, including 41,000 who fell off ladders and 5,800 who were seriously hurt by hammers. So I won't be going down to the hardware store. How did Pete spend his holiday in the past? A) Visiting his friends. B) Diving. C) Travelling around the world. D) Making his house beautiful.
