A new study finds that the concave-eared torrent frog that uses ultrasonic communication can tune its ears like a radio dial to block out lower pitched background noise. 18 This is contrary to everything that we knew about the frog’s auditory system.

Earlier this year, the researchers reported that male torrent frogs can localize sound with unusual accuracy to find females during ultrasonic mating duets. 19 This surprised the team, because in all other frogs eardrums always respond the same way to a sound stimulus.

Further examination revealed that the frogs were actively opening and closing their eustachian tubes, two narrow channels that connect the mouth cavity to the left and right ear. 20 In practice, shifting to high-frequency hearing could help the frogs pick out mating calls during a storm, when the low-pitched noises of plunking raindrops, booming thunder, and rushing water dominate. 21

【題組】20
(A) Closing the tubes improved the frogs’ ability to hear high frequencies and ultrasounds, while opening them increased sensitivity to low-frequency noises.
(B) Further studies of the amphibian’s hearing showed that its eardrums vibrate in response to ultrasonic noises, but only some of the time.
(C) By contrast, the frogs have evolved the biological equivalent of earmuffs to block out all sounds of a certain frequency range.
(D) In other words, the frogs’ tunable ears are an adaptation to their noisy home environments.

4(A).

When provided with continuous nourishment, trees, like people, grow “complacent”—the word tree-ring scientists use to describe trees like those on the floor of the Colorado River Valley, whose roots tap into thick reservoirs of moist soil. Complacent trees aren’t much use for learning about climate history, because they pack on wide new rings of wood even in dry years. To find trees that feel the same climatic pulses as the river, trees whose rings widen and narrow from year to year with the river itself, scientists have to climb up the steep, rocky slopes above the valley and look for gnarled, ugly trees, the kind that loggers ignore. For some reason such “sensitive” trees seem to live longer than the complacent ones. “Maybe you can get too much of a good thing,” says Dave Meko, a tree-ring scientist who has been studying the climate history of the western United States for decades. Tree-ring fieldwork is hardly expensive, but during the relatively wet 1980s and early ’90s, Meko found it difficult to raise even the modest funds for his work. “You don’t generate interest to study drought unless you’re in a drought,” he says.
【題組】48 Why aren’t complacent trees good for studying climate history?
(A) Their rings are too narrow.
(B) They are not well-nourished.
(C) They do not reflect genuine climate change.
(D) They are reserved for loggers for good prices.

5(A).

13 If you are deeply engaged in performing an activity, you’ll be less amenable to a distraction.
(A) If your mind wanders off, it’s because the work you’re doing is not interesting.
(B) If you are fully absorbed in what you’re doing, you won’t be easily distracted.
(C) If you are engaged to a person you love, there will be no one to distract you.
(D) If you work deeply on an interesting activity, your work will be less amenable.
