读某大陆沿西海岸线降水量空间变化图，完成下列问题。
小题1:该大陆是
A．亚欧大陆
B．非洲大陆
C．南美大陆
D．澳大利亚大陆小题2:图中纬度10°～20°地区降水少的主要原因是
A．纬度低，蒸发旺盛
B．终年盛行东北信风，水汽含量少
C．受副热带高压控制，盛行下沉气流
D．沿岸有寒流流经，降温减湿明显
小题1:C
小题2:D
题目分析：
小题1:图示大陆西海岸分布在南纬10°到南纬60°，所以不可能是亚欧大陆和非洲大陆，只有南美大陆在该纬度范围内有大陆分布，降水量变化趋势符合图示趋势，澳大利亚大陆只在南纬10°到南纬40°之间，故答案选C。
小题2:图中纬度10°～20°地区为东南信风带，西海岸位于安第斯山脉的西侧，处于背风地带，而且沿岸有实力强盛的秘鲁寒流流经，降温减湿明显，降水少，故答案选D。
