问题 综合

(22分)阅读图文资料,结合所学知识完成下列要求。

某校地理信息小组将所搜集资料进行整理后,向全班同学做了汇报交流。下图所示M区域1(阴影区)约占某国陆地面积的23%。通过该国政府的支持和科研人员的努力,这片昔目的荒原,现如今已变成可以实施大规模机械化生产的世界新粮仓,在该国M地有“谷物带”之称。

(1)推测M地区利于发展大规模机械化农业生产的自然条件。(6分)

(2)简述农业科研人员在改造M地区时可能采取的有利措施。(8分)

(3)该小组认为M地的农业生产模式可以复制到同纬度的非洲东部地区。听汇报的思思同学提出了“不宜在非洲复制”的相反看法,请为该同学的反驳提供论据。(8分)

答案

(22分)

(1)地处热带高原地区,地域开阔,地势较平坦(或地表环境较单一)。(6分)

(2)改良酸性土壤(添加熟石灰、增施有机肥)提高肥力;培育新作物品种;改进灌溉技术;提高粮食作物产量等。(8分)

(3)(同纬度的非洲地区)自然条件虽然与M地相似,但地表状况略显复杂,(2分)经济水平,科研能力仍然较低,农业生产技术较落后。(6分)

题目分析:

(1)依据图中信息可以看出,M地在巴西高原上,地处热带,热量丰富,高原地区,地域开阔,地势较平坦,土地集中连片,有利于大型机械作业,利于发展大规模机械化农业生产。

(2)M地地处热带,植被茂盛,土壤中酸性物质含量较高,酸性强,应改良酸性土壤,添加熟石灰、增施有机肥,以提高肥力,加大科技投入,培育新作物品种,改进灌溉技术,提高粮食作物产量等。

(3)同纬度的非洲地区自然条件虽然与M地相似,但非洲同纬度地区位于非洲断裂带上,地表状况略显复杂,再加上经济水平和科研能力仍然较低,农业生产技术较落后,所以大规模机械化生产在非洲同纬度地区推广有较大难度。

         Many years ago, I was fresh out of school and working in Denver. I     1     to my parents' home in
Missouri     2      Christmas when my car almost ran out of gas. I stopped at      3       gas station about 50
miles from Oklahoma City. I was planning     4      and visit a friend there. While I was standing in line at the
cash register (收款台), I said hello to an older couple (夫妇)     5      were also paying for gas.
          I drove away,     6      had gone only a few miles when black smoke came from the back of my car. I
stopped and wondered      7      I should do. A car stopped behind me. It was the couple I had spoken to at the
gas station. They said they      8      me to my friend's.
         When I got home, I wrote him and his wife a thank-you note for helping      9      . Soon afterward, I
received a Christmas present from them. Their note that came with said that helping me had made their holidays
    10    .
         "Thank you" —two powerful words. They're easy to say and mean so much.
