Select missing word一直是PTE听力考试里比较难的一种题，因为没有什么背景，忽然让你听一串话，然后后面就没有了。考生需要在四个选项中找到最合适的一个选项。对于这种题，考生一定要注意内在的逻辑，尤其是顺和转这两种逻辑。今天我就通过两题来给大家讲解写背后的逻辑：

　　比如： …. However, this method was problematic in terms of accuracy; but nevertheless, it has been used for countless years, from early humanity to________.

　　Ancient civilisations

　　Desert tribes

　　Historical periods

　　Current days

　　前面介绍了一直方法。后面出现however转折，接下来又出现转折 but nevertheless, from early humanity to 后面自然应该是到现在。。。所以答案是：D.

　　…. However, many scholars are skeptical about the authenticity of the blocks, which they suspect________.

　　前面说了一大段，没有听懂也没有关系。只要你听到了后面的skeptical怀疑的， authenticity 真实性就可以。

　　后面的三个选项：

　　are much older than expected

　　could very possibly be fake

　　belonged to that culture.

　　所以正确答案是B。
