【題目】 2019年1月3日10時(shí)26分，嫦娥四號(hào)探測(cè)器成功著陸在月球背面預(yù)選著陸區(qū)，并通過(guò)“鵲橋”中繼星傳回了世界第一張近距離拍攝的月背影像圖，此次任務(wù)實(shí)現(xiàn)了人類探測(cè)器首次月背軟著陸、首次月背與地球的中繼通信，開啟了人類月球探測(cè)新篇章。但是我們對(duì)地球的認(rèn)識(shí)卻經(jīng)歷了一個(gè)漫長(zhǎng)的過(guò)程。

據(jù)此回答下列各題。

【1】人類對(duì)地球形狀的認(rèn)識(shí)進(jìn)入科學(xué)探索階段始于（ ）

A. “渾天說(shuō)”提出時(shí)期

B. “天圓地方”提出時(shí)期

C. 前蘇聯(lián)宇航員加加林飛入太空以后

D. 麥哲倫實(shí)現(xiàn)環(huán)球航行后

【2】發(fā)射嫦娥四號(hào)的火箭回收一般選擇地勢(shì)平坦，植被、人煙稀少的地區(qū)進(jìn)行，既便于回收，又能保障人員安全，那下列地形中，最合適的是（ ）

A. 高原B. 山地C. 丘陵D. 峽谷

【答案】

【1】D

【2】A

【解析】

【1】人類對(duì)地球形狀的認(rèn)識(shí)經(jīng)歷了一個(gè)漫長(zhǎng)的階段，古代人們提出的一些是不科學(xué)的，只有近代麥哲倫環(huán)球航行才使人們對(duì)地球形狀的認(rèn)識(shí)進(jìn)入科學(xué)探索階段，故選D。

【2】發(fā)射嫦娥四號(hào)的火箭回收一般選擇地勢(shì)平坦，植被、人煙稀少的地區(qū)進(jìn)行，既便于回收，又能保障人員安全，最適合返回的地形是高原，山地、丘陵和峽谷地勢(shì)崎嶇不平，不利于回收，故選A。

本題考查地球形狀有關(guān)知識(shí)，要知道地球形狀認(rèn)識(shí)的過(guò)程。
