【題目】晚上,北京的暢暢給美國紐約的姑媽打電話說上午好。完成下面小題。

1暢暢打電話時(shí)北京是晚上,紐約是上午,造成這種時(shí)間差異的原因是

A.地球的公轉(zhuǎn)B.地球的自轉(zhuǎn)

C.月球公轉(zhuǎn)D.地球是球體

2暢暢想知道姑媽家所在的位置,應(yīng)查找的地圖是

A.世界地形圖B.世界氣候類型分布圖

C.世界人口圖D.世界的國家和地區(qū)圖

【答案】

1B

2D

【解析】

根據(jù)地球繞地軸不停轉(zhuǎn)動(dòng),叫地球自轉(zhuǎn)。地球自轉(zhuǎn)的方向是自西向東,自轉(zhuǎn)的周期是一天。地球自轉(zhuǎn)產(chǎn)生的現(xiàn)象是晝夜交替、日月星辰東升西落和時(shí)間差異;地圖是學(xué)習(xí)地理必不可少的工具。人們從地圖上可以直接獲得大量有用的地理信息。我們要掌握使用地圖的方法,在日常生活中養(yǎng)成經(jīng)常讀圖、用圖和收集地圖的好習(xí)慣,進(jìn)行分析解答。

1地球自轉(zhuǎn)產(chǎn)生了不同經(jīng)度地方時(shí)的差異,較東邊的地方比較西邊的地方時(shí)刻更早。北京與紐約經(jīng)度差異大,因此北京是晚上,紐約是上午。故選:B。

2在日常生活中,我們應(yīng)根據(jù)實(shí)際需要選擇合適的地圖。暢暢想知道美國紐約姑媽家所在的位置,應(yīng)查找的地圖是世界的國家和地區(qū)圖。故選:D。

本題考查了地球自轉(zhuǎn)產(chǎn)生的時(shí)間差異及地圖的選擇。

【題目】讀資料回答問題。

節(jié)水農(nóng)業(yè)要“量水而種”,面對(duì)今春引黃灌溉水量嚴(yán)重短缺的緊迫形勢(shì),寧夏河套灌區(qū)掀起一股打井抗旱保春耕的熱潮。許多專家學(xué)者和水利工作者提出,開發(fā)地下水資源,固然是當(dāng)前解決寧夏河套灌區(qū)農(nóng)業(yè)灌溉用水緊張狀況的重要手段,但也應(yīng)堅(jiān)持“量水而種”的原則,大面積壓縮高耗水的農(nóng)作物,在農(nóng)業(yè)種植結(jié)構(gòu)調(diào)整中“找水”。一提節(jié)水灌溉,許多人首先想到的是工程節(jié)水,如砌護(hù)渠道、實(shí)行低壓管灌、上噴灌設(shè)施多,其實(shí)這只是節(jié)水農(nóng)業(yè)的一個(gè)方面。實(shí)踐表明,運(yùn)用科學(xué)技術(shù)調(diào)整工業(yè)種植結(jié)構(gòu)進(jìn)行節(jié)水,同樣大有可為。

在寧夏鹽池縣城西灘、紅寺堡扶貧開發(fā)區(qū),近年部分農(nóng)民在政府的引導(dǎo)下,調(diào)整種植業(yè)結(jié)構(gòu),引種耐旱飼草苜蓿,每年只需灌溉兩到三次水便可獲得豐收。

調(diào)整單一的農(nóng)業(yè)種植結(jié)構(gòu),改變的不單單是用水方式,對(duì)農(nóng)民增收也會(huì)產(chǎn)生很大影響!爸袊坭街l(xiāng)”中寧縣的農(nóng)民,紛紛壓縮糧食種植,擴(kuò)大高效節(jié)水經(jīng)濟(jì)作物枸杞的種植面積,經(jīng)營一畝地的枸杞,每年不僅比種糧少灌幾次水,還能獲得種糧5倍以上的經(jīng)濟(jì)收入。

(1)寧夏地理位置有什么特點(diǎn)?請(qǐng)分析寧夏發(fā)展農(nóng)業(yè)生產(chǎn)的條件。

(2)黃河流經(jīng)寧夏,對(duì)寧夏而言,發(fā)展節(jié)水農(nóng)業(yè)是否必要?

(3)寧夏發(fā)展“節(jié)水農(nóng)業(yè)”采取了哪些措施?收到了怎樣的效果?
