A．图中等温线分布的主导因素是洋流
B．甲河下游沿岸温带落叶阔叶林广布
C．乙河流经地区地形平坦，航运条件好
D．E处春季出现凌汛的时间比F处早小题2:铁路分布在该区南部的主要原因是南部

B．地势低平，便于施工建设
C．矿产丰富、人口城镇众多
D．邻国众多，便于经济联系
小题1:D
小题2:C
题目分析：
小题1:读图可知，该地区位于俄罗斯地区。图中等温线分布的主要因素是纬度；甲河下游沿岸为广阔的亚寒带针叶林带；乙河流经地区，由于纬度高，结冰时间长，航运条件差；EF两处虽然纬度差不多高，但是由于E处受西风带影响更大，所以较F处温暖一些，春季河水融冰时间早一些。
小题2:该地区由于纬度较高，气温较低，所以人口和城市主要分布在南部地区，且南部地区矿产资源较丰富一些，铁路的修建便于城市之间联系和人口流动。
“USA? Britain? Which country is better to study in?” We often hear such discussions. As China open its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world. It’s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs. But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language. Students must also learn to live without parents’ care and deal with all kinds of things they haven’t to do before, like looking after themselves. There are reports about Chineses students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well. Finally, studying abroad brings a heavy burden to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it? We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you winder which country is better to study in, think it again.
