IV. Cloze TestThough many stories from around the world describe behavioralchanges in various animals in the days and hours before an earthquake,research testing animals’ ability to predict earthquakes has been (28).Recently, however, scientists were able to document the behaviors of agroup of toads before, during, and after an earthquake. Researcherswere studying the breeding habits of a particular group of toads, when,suddenly, 96 percent of the males simply (29) for a five-day period. Asignificant earthquake and several aftershocks (30) on the fifth dayafter the departure. Six days after the last aftershock, the malesreturned and resumed mating, as if (31) had happened. It turns out thatprior to the earthquake, there had been subtle changes in the Earth’smagnetic field, and an increase in the amount of radon gas in thegroundwater.

Cloze測試雖然世界各地的故事描述了地震前幾天和幾個小時各種動物的行為變化，但研究測試動物預測地震的能力已經是（28）。最近，科學家們能夠在地震之前，之中和之後記錄一群蟾蜍的行為。研究人員正在研究特定蟾蜍群體的養殖習慣，突然間，96％的男性只需（29）為期五天。出發後第五天發生重大地震和幾次餘震（30）。最後餘震六天后，男性又返回並恢復交配，彷彿（31）發生了一切。事實證明，在地震之前，地球的磁場發生了微妙的變化，地下水中氡氣的數量也在增加。 （32），上層大氣中有異常的電氣乾擾。來自google翻譯
