【題目】讀下面材料,回答問題。
材料一 前些年,記者在陜北的一個窮山溝里與一個放羊娃有一段對話:“今年多大了?”“十六!”“怎么不上學(xué)?”“我放養(yǎng).”“你放養(yǎng)是為了什么?”“掙錢。”“掙錢干什么?”“娶媳婦!薄叭⑾眿D干什么?”“生娃娃!薄吧尥迣⒗锔墒裁?”“放養(yǎng)!
材料二 在地球北緯200--300緯度帶上的大陸西部是降水很少,氣候干旱,沙漠廣布的阿拉伯半島,而我國處于這一緯度帶上的長江以南地區(qū),則降水豐沛,氣候濕潤,物產(chǎn)豐富,被人們稱為“魚米之鄉(xiāng)”。兩地的氣候差別非常大。
(1)材料一反映了陜北地區(qū)存在的什么問題?應(yīng)如何解決?
(2)材料二反映了在同緯度中阿拉伯半島和我國大陸氣候有什么差異?我國大陸氣候有什么特征,這種氣候特征對我國發(fā)展農(nóng)業(yè)生產(chǎn)有什么好處?
【答案】(1)材料一說明陜北的某些地方,人們的文化水平低,思想觀念落后,人口素質(zhì)亟待提高。措施:應(yīng)大力發(fā)展科學(xué)文化教育,使更多的人接受良好的教育,改變落后的思想觀念,大力提高人口素質(zhì)。
(2)材料二反映了同緯度中阿拉伯半島降水很少,氣候干旱,而我國則降水豐沛,氣候濕潤。我國大陸的大部分地區(qū)處于季風(fēng)區(qū),季風(fēng)氣候具有“雨熱同期”的特征。 “雨熱同期”是我國優(yōu)越的氣候資源,夏熱給我國廣大北方地區(qū)帶來足夠的溫度,使得廣大北方地區(qū)都能種植棉花、水稻、玉米等喜溫作物;夏雨又使農(nóng)作物在夏季生長旺盛期得到充足的水分。使我國的農(nóng)作物資源及其豐富。
【解析】
(1)材料一從放羊娃與記者的交談中可以看出,陜北的窮山溝里,人們的文化水平低,思想觀念落后,人口素質(zhì)亟待提高。針對此問題,應(yīng)大力發(fā)展科學(xué)文化教育,使更多的人接受良好的教育,改變落后的思想觀念,大力提高人口素質(zhì)。
(2)從材料二中可知:在地球北緯20°--30°緯度帶上的大陸西部是降水很少,氣候干旱,沙漠廣布的阿拉伯半島,而我國處于這一緯度帶上的長江以南地區(qū),則降水豐沛,氣候濕潤,物產(chǎn)豐富,被人們稱為“魚米之鄉(xiāng)”。所以反映了阿拉伯半島和我國大陸氣候差異:阿拉伯半島降水很少,氣候干旱,而我國則降水豐沛,氣候濕潤。我國大陸的大部分地區(qū)處于季風(fēng)區(qū),季風(fēng)氣候具有“雨熱同期”的特征。“雨熱同期”說明我國夏季水熱組合狀況好,夏熱給我國廣大北方地區(qū)帶來足夠的溫度,使得廣大北方地區(qū)都能種植棉花、水稻、玉米等喜溫作物;夏雨又使農(nóng)作物在夏季生長旺盛期得到充足的水分,使我國的農(nóng)作物資源及其豐富。
