2 答案:BC
解析:(31”)定位句:First of all, let me talk about how we have been able to get past those clouds. First, there were Soviet modules that landed directly on the surface and sent back some images of what was around them. Second, we did some radar imaging from satellites from above 教授先说,让我说说我们怎么穿过那些云的,第一是直接落在表面,然后传回一些图像显示有什么东西在他们的周围,第二,一些雷达从卫星上获得,所以选择BC
3 答案:AC
解析:(2’12”)定位句:But what's particularly interesting about these volcanoes is that most of the volcanoes here on Earth are not shield volcanoes. Instead, they are other volcano types, like strata volcanoes, for example, which are a result of tectonic plate movement 这句话之前,有一个大停顿,之后来了个But!说Venus 上几乎都是这种shield volcanoes。选择A!Instead 又紧接其后,说地球可不是这样,地球上的火山都是因为地壳运动形成的。其实这里如果听懂了地壳运动就可以做题了,但是如果不幸你不懂,就接着往下听一句,教授解释了一下,也无障碍了。C 也选出来了。
4 答案:D
解析:(3’20”)定位句:So why doesn't Venus have them? Well, there are a few theories. Venus 表面没有水是在这个问题之后说的,显然是解释这个问题用的。问答是考点,没啥可说的,选择D
5 答案:A
解析:(easyvoa.com)定位句:It's quite possible that this is due to volcanic eruptions, because volcanic eruptions often emit gases. 全是因果词,提示词。说这很有可能是因为火山的爆发从而释放气体,从而形成了云,选A
6 答案:B
解析:(5’02”)定位句:So this too suggests ongoing volcanic activity. But although this is intriguing evidence, no one's actually observed a Venus volcano erupting yet, so we can't be positive. 教授说,这也证明了金星的火山是活跃的,但是没啥直接的证据,也没人真的看到火山爆发。显然教授是对这两个theory 持怀疑态度的,但是至少有两个证据证明,所以选B
