B. 采用节水措施;开发利用无污染能源
C. 多种水稻;充分利用风能
D. 维持能源消费结构现状;自备购物袋
【答案】
【1】A
【2】B
【3】A
【解析】
【1】请在此填写小题的解析! 本题主要考查全球变暖对自然环境和人类活动的影响,可调用课本相关内容分析,属于知识性试题。火山、地震的发生主要是由于地球内力作用的结果,而与全球气候变暖关系不大,①错误;由于气候变暖,地球南北两极的冰山融化,造成海平面上升,海平面上升会使沿海的低地和岛屿被淹,②正确;气候变暖,会使温带地区树枝提前萌发新芽,③正确;全球变暖还会使高温、热浪、 热带风暴、龙卷风等自然灾害加重,全球灾害性天气频繁出现。由以上分析②③④正确,答案选A项。
【2】 由于全球变暖对全球降水量的影响,低纬度地区农作物的产量一般呈下降趋势,A错误;全球气候变暖,冬季气温升高,故中纬度地区采暖耗能减少,B正确;全球变暖,北温带地区温度升高,热量增多,北温带的南部地区可能不再适合小麦的种植,导致小麦种植面积减小, C错误;温带地区由于气温升高,冬季的寒冷天气减少,故病虫害将增多,D错误。故答案选B项。
【3】本题主要考查缓解全球气候变暖的措施。首先要明确全球变暖的原因和公众参与的含义,全球温度升高,既有自然原因,也有人为原因,而人类生产和生活中向大气排放大量二氧化碳等温室气体是其最主要的原因,因此,充分利用太阳能、尽量使用公共交通工具等可以减少化石燃料的消耗,减少二氧化碳的排放,从而有利于控制全球变暖,A正确;采用节水措施能够缓解水资源短缺问题,但对节能减排作用不大,B错误;多种水稻属于农业结构的调整,对节能减排作用不大,C错误;我国能源消费结构不合理,以煤炭矿石燃料为主,如果维持能源消费结构现状,不会改变二氧化碳的排放状况,D错误。故答案选A。

A garden that’s just right for you
Have you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts? 1 . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.
● 2
Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料). 3 . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.
●Recall(回忆)your childhood memories
Our model of what a garden should be often goes back to childhood. Grandma’s rose garden and Dad’s vegetable garden might be good or bad, but that’s not what’s important. 4 —how being in those gardens made us feel. If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth. 5 then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.
A. Know why you garden
B. Find a good place for your own garden
C. It’s our experience of the garden that matters
D. It’s delightful to see so many beautiful flowers
