分析下面的材料,回答问题:

材料一某市8月份的两条街道昼夜温度变化曲线图

材料二北京市绿化方面,全部按照适地适树和植树多样性原则,注重了高大乔木、亚乔木、花灌木的空间配置,落叶树种和常绿树种的合理搭配和植物色彩的季相变化,并选用了40多种树种,使绿化隔离地区和“五路十河”绿化通道形成了“三季有花、四季常青”的优美景观。

2003年北京城市绿化主要突出了城市森林景观,注重了树种组团配置和植物季相变化,已经形成了多个精品工程。目前,全市绿化隔离地区绿化面积已大大提高,形成了一批以文化、体育、休闲为主体,满足市民需要的绿色产业项目。

(1)图中代表绿化街道的温度变化是()。

(2)从图中可看出,夏季树木在改变城市气候方面的主要作用是();其主要原因是()。

(3)绿化在改善城市环境中的作用还有()。

(4)结合材料二分析,在全国很多大城市绿化工程主要是修建大型草坪、花园等时,北京城市绿化却提出了突出城市森林景观,改变种植方式,注重树种选择、植物季相变化等措施,这是否可行

(5)谈谈你对城市绿化发展与保护的看法,你认为可采取哪些合理的措施

答案

参考答案:

(1)A

(2)降低白天气温;绿地热容量大于裸地

(3)减弱噪声,美化环境,增加大气湿度,净化空气,吸烟滞尘等

(4)可行。北京是我国的首都,是我国的政治、文化中心,应该成为我国对世界的窗口,应该用美丽的花、草、树木展现祖国的美丽;北京是一个历史悠久的大都市,无论怎样绿化或建设都必须保护其古老的风格,一方面充分地让空地绿起来,另一方面不破坏古迹等;北京地处华北地区,属温带大陆性气候,目前人多车多,干旱、缺水严重,常有大风、沙尘等天气发生。

(5)加强城市规划,确保绿地面积比例;加强管理,保护绿地;发展立体绿化,如在屋顶、阳台等处绿化。

Driving a car at a high speed along a highway seems to be fun. You only need to follow the

bright traffic signs beside the highway and it will take you where you wish to go.

But to a London taxi driver, driving is not an easy job. A taxi driver needs to have not only good driving skills but also a good knowledge of the city of London, from the loneliest street to the popular restaurant around. He has to be at the service of all kinds of passengers (乘客) at all times.

A London taxi driver said the following about his job.

During the night it is usual for him to stop two or three times for some food. He said, “I never drink when I’m working, otherwise I’d lose my license (驾驶执照).”

He normally goes home between two and three o’clock in the morning. There are times he has to stay longer and try to make more runs. He said, “That’s the worst thing about working for yourself. If you don’t make money, no one is going to give it to you. ”

London taxi drivers not only “take” but also “give”. Every summer hundreds of poor children from London go for a day at the sea ― by taxi! There rides are paid by the taxi drivers. At the sea, they are met by the mayor (市长) , and a lunch party is also held for the taxi drivers and the children. After a happy day’s running around the beaches and visiting the market there, the children go home again by taxi, free of charge of course!
