【題目】近20多年來，我國經(jīng)濟發(fā)展速度高居世界前列，但是各地發(fā)展速度有所不同，尤其是東部與西部的經(jīng)濟差距逐漸擴大，國家實施了西部開發(fā)戰(zhàn)略，據(jù)此完成下面小題。

【1】【1】制約西部經(jīng)濟發(fā)展的主要社會經(jīng)濟因素是( )

A. 資金、技術不足 B. 水源不足

C. 能源短缺 D. 勞動力匱乏

【2】【2】為了改善西部交通條件，我國實施的重點工程之一的是( )

A. 西氣東輸 B. 青藏鐵路

C. 西電東送 D. 南水北調(diào)

【答案】

【1】【1】A

【2】【2】B

【解析】試題分析：

【1】【1】我國西部地區(qū)資源豐富,地廣人稀但產(chǎn)業(yè)結(jié)構不合理,農(nóng)業(yè)產(chǎn)業(yè)化水平低,城鄉(xiāng)一體化進程緩慢,縣域財力匱乏,從而導致其經(jīng)濟發(fā)展相對落后。在發(fā)展生態(tài)農(nóng)業(yè)的基礎上,大力發(fā)展農(nóng)副特色產(chǎn)品的加工業(yè),加強區(qū)域間聯(lián)合,發(fā)展民營經(jīng)濟,加強教育和人力資源開發(fā),是解決西部縣域經(jīng)濟發(fā)展的基本對策。故選A。

【2】【2】四選項中，只有青藏鐵路是為了改善西部交通條件而修建的。故選B。
