Sometimes,they even plan whole new cities.  City planners are 25       about the problems of CBDs (Central Business District) . How can these busy areas meet the needs of both people and businesses? The city of Fresno has 26        up good answers to this question. Not long ago,the CBD there was crowded and ugly. It was hard to walk there 27        there were so many cars and trucks.

First,they made it look much 28       ,They planted trees,built fountains (喷泉) ， 29       the older buildings in the CBD and even built new ones.

Then the city planners said that 30        cars could drive into the CB   D. People could park their cars in nearby parking places,but they had to either walk into the CBD 31       take little electric cars. Today,Fresno's CBD is a good place to visit.
