题目

How did the sea horse get its name? It’s not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse’s tail, you might think “sea monkey” is a better name. Then there’s the sea horse’s pouch (袋). “Sea kangaroo” might also be a good name for this fish. Sea horses live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings (环境). A sea horse remains in one place for hours at a time by winding (缠绕) 住宅间距, 综合考虑采光等因素,以满足日照要求为基础，北半球冬至日照时间不低于1小时（房子最底层窗户）为标准，L（日照间距） = x（日照间距系数）×H（楼高），下图是“我国主要城市日照间距系数图”，回答：图中纵坐标表示日照间距系数，a-z代表城市，曲线I、II、III表示的日照时间分别为10：30 、13：30；中午12时；11:00、13：00，下列说法正确的是A.纬度越高，日照间距系数理论值越大，实际日照间距与理论值差距越大B.图中日照间距系数理论值综合考虑了城市大小和土地成本C.表示日照时间为10：30 —13：30的曲线是ID.若 z代表齐齐哈尔、w代表乌鲁木齐，则y代表沈阳同一地理纬度的同一日照标准，无其他日照遮挡的平行布置条式居住建筑之间A.冬至日正午太阳高度30º的城市，日照间距系数约为1.4B.楼房正面朝向与子午线夹角越大日照间距折减率越小C.日照标准大城市大寒日大于2小时高于小城市冬至日大于1小时D.日照间距一定时，居住楼层越高达到日照标准的可能性越大
