  答案与题解:

  1. D 短文第一段的第一句告诉我们,英国研究人员正在测试一种仪器,这种仪器可以通过监测土壤的振动来预警山崩。该段最后一句说,这种灾难经常在一些遭受自然灾害的国家发生,这些自然灾害包括sudden,heavy rainfall和earthquakes以及water erosion.所以D是正确选择。

  2. D A、B、C的内容都可在第二段中找到。所以D是正确答案。

  3. C 第三段的第一和第二句告诉我们,最为普通的监测山崩方法是对山坡形状变化的观察,有两种观察方式;第三句说,因为山坡形状的变化不一定导致山崩,所以两种方法都会有虚假的预警。因此,C是正确答案。

  4. A B、C、D所述内容都可在第四段中找到。The borehole is filled in with gravel around the pipe.在被凿出的洞里填充沙砾,围在钢管四周。不是在钢管里填充沙砾。所以A是错误的说法,是正确的选择。

  5. B positives在此用作名词,意思是:被证实的因素或特点,可以理解为证据。
