The sale of Alaska was not so much an American coup as a matter of ______ for an imperial Russia that was short of cash and unable to ______ its own continental coastline.
我是根据后面was short of cash and unable to ______ its own continental coastline来判断当时Russia的情况比较困窘...在当时那种境况下最好的办法就是卖了阿拉斯加... 所以是权宜之计.... 而且老杜特地在课上见过这道...你可以搜搜音频去... 他还特别讲了这道的背景...当时美国购买阿拉斯加好多人都反对...但后来在阿拉斯加发现了石油...美国才发现占了大便宜...后来俄罗斯知道了后悔不已...想再买回来...但是美国不卖了...
