Filling the blanks (选词填空)是PTE阅读考试中一个比较容易失分的部分，大家往往认为FIB是单纯对词汇量的考察，而忽略了题目在固定搭配，一词多义等考察点所设置的陷阱。

In a report released on January 23, a team of British researchers says the deadlyupwellingbegan when an exploratorygas well punched through a layer of rock 9300 feet (2800 meters) below the surface,allowinghot, high pressure water toescape. The watercarriedmud to the surface, where it hasspreadacross a region 2.5 miles (4 kilometers) indiameterin the eight months since the eruption began. The mud volcano is similar to a gusher or blowout, which occur in oil drilling when oil or gas squirt to the surface, team says. This upwelling, however, spews out a volume of mud equivalent to a dozen Olympic swimming pools each day. Although the eruption isn't as violent as aconventionalvolcano, more than a dozen people died when a natural gas pipeline ruptured. The research team, who published their findings in the February issue of GSA Today, also estimates that the volcano, called Luis, will leave more than 11,000 people permanently displaced.

　　印尼爪哇岛的天然气钻探引发了一场“泥火山”，已造成13人死亡，并可能导致4平方英里(10平方公里)的乡村地区多年无法居住。在1月23日发布的一份报告中，一组英国研究人员表示，致命的上涌开始于一口探井在地表以下2800米(9300英尺)的岩层中钻出，使得高温高压的水得以流出。自火山爆发以来的8个月里，水将泥浆带到了地表，并在地表蔓延了2.5英里(4公里)的直径。研究小组说，这座泥火山与喷油井或井喷类似，喷油井或井喷发生在石油钻探过程中，石油或天然气喷射到地面。然而，这些上涌物每天喷出的泥浆量相当于12个奥运游泳池。尽管这次火山喷发不像传统火山那么猛烈，但一条天然气管道破裂导致十多人死亡。研究小组在今天出版的《GSA》2月刊上发表了他们的研究结果。他们还估计，这座名为“卢西”的火山将导致1.1万多人永久流离失所。
