【題目】下列敘述中，正確的是：

A. 南方地區(qū)的河流冬季都有結(jié)冰現(xiàn)象。

B. 南方地區(qū)的主要糧食作物是小麥，北方地區(qū)的主要是水稻

C. 南方地區(qū)熟季為一年兩熟到三熟，北方地區(qū)一年一熟或兩年三熟

D. 南方地區(qū)和北方地區(qū)的農(nóng)業(yè)都以旱作為主

【答案】C

【解析】秦嶺、淮河把我國東部地區(qū)分為南方和北方，北方地區(qū)到了冬季，氣溫在0℃以下，河流普遍有結(jié)冰現(xiàn)象，南方地區(qū)冬季氣溫在0℃以上，河流不會結(jié)冰，故A說法是錯誤的；我國主要糧食作物的分布，受地形和氣候等多種因素的影響，南方以種植水稻為主，北方以種植小麥為主，故B說法是錯誤的；南方地區(qū)為亞熱帶，熟制為一年兩熟到三熟，北方地區(qū)為暖溫帶和中溫帶農(nóng)作物一年一熟或兩年三熟故C說法是正確的；我國耕地類型受地形和氣候等多種因素的影響，南方種水田，北方種旱地，故D說法是錯誤的。故選C。

【題目】 One day, a student was taking a walk with a professor. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer’s, who was working in the field nearby.

The student turned to the professor and said, “We will hide his shoes, then hide ourselves behind those trees, and wait to see what he will do.”

“My young friend,” answered the professor, “We should never make fun of the poor.
