【題目】下圖為“沿106.5°E我國局部地形剖面圖”，回答下列各題。
【1】圖中①地形區為
A．黃淮海平原 B．四川盆地
C．江漢平原 D．黃土高原
【2】關于③地形區的特點，描述正確的是
A．冰川廣布，平坦開闊

D.冬季溫暖，河網密布，水土流失嚴重
【答案】
【1】D
【2】B
【3】D
【解析】
試題分析：
【1】圖示為沿106.5°E我國局部地形剖面圖，圖中①地形區位于秦嶺北側，是黃土高原，D對。黃淮海平原位于115°E以東地區，A錯。四川盆地位于秦嶺以南，B錯。江漢平原 位于110°E以東，C錯。
【2】根據經度和地形剖面圖，③地形區位于四川盆地南側，是云貴高原，喀斯特地貌廣布，地表崎嶇，B對。緯度低，海拔較低，沒有永久冰川分布，地形崎嶇，A錯。千溝萬壑，支離破碎是黃土高原的景觀，C錯。遠看是山，近看成川是青藏高原的寫照，D錯。
【3】結合前面分析，②地區是四川盆地，由于四面高山環繞，盆地內冬季溫暖，河網密布，水土流失嚴重，D對。土壤肥沃，沒有鹽堿化問題，A錯。盆地內部是有主要商品糧基礎，不是牧區景觀，B錯。 水土流失嚴重，小流域宜打壩淤地是黃土高原的特征。

California Condor’s Shocking Recovery
California condors are North America’s largest birds, with wing-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning(鉛中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.
In the late 1980s, the last few condors were taken from the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.
Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(電死) if they touch two lines at once.
So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.
Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(腎) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011.
Rideout’s team thinks that the California condors’ average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them. ”
