Complete the summary below.
Choose NO MORE THAN THREE WORDS from the passage for each answer.
Write your answers in boxes on your answer sheet.
How the elephants sense these sound vibrations is still unknown, but O’Connell-Rodwell, a postdoctoral researcher at Stanford University, proposes that elephants are ’listening’ with their【R1】________by two kinds of nerve endings that respond to vibrations with both【R2】________frequency and slightly higher frequencies. O’Connell-Rodwell’s work is at the combination of geophysics, neurophysiology and【R3】________.
It was known that seismic communication existed extensively within small animals, but O’Connell-Rodwell was the first person to indicate that a large land animal would send and receive【R4】________too. Also, he noticed the freezing behaviour by putting a male planthopper on a stem and play back a female call, which might prove the existence of other communicative approaches besides【R5】________.
Scientists have determined that an elephant’s ability to communicate over long distances is essential, especially, when elephant herds are finding a【R6】________, or are warning of predators. Finally, the results of our 2002 study showed us that elephants could detect warning calls through the【R7】________.
【R2】
选项
答案
infrasonic/low
解析
……通过两种神经末梢来对震动产生反应,一种对什么频反应,一种对相对高频的反应。同样通过nerve endings定位到第4段第4句,two types of对应题干two kinds of,其后破折号之后的内容正是题干的问题。其中,vibrations higher in frequencies对应slightly higher frequencies,与其并列的infrasonic vibration对应题干________frequency。空白处填一个形容词即可,省去vibration。此外,原文第1段最后1句提到:…low-frequency sounds,also known as infrasounds,所以空白处填low也不算错。因此,本题的答案为infrasonic/low。
