問題詳情
Ⅱ. Cloze（每題 1 分） Can plants hear? Michael Marshall claims in New Scientist that plants might hear sounds. Hementions that Monica Gagliano led a team to conduct some experiments about how chilli peppers sensedneighboring plants even if those neighbors were sealed in a box. They placed some seeds of chilli peppersinto eight Petri dishes (11) a potted sweet fennel plant, one kind of plant which releases chemicalsinto the air and soil that slow other plants’ growth. This team also prepared some experimental setups (12) the fennel was enclosed in a box and thus its chemicals would be blocked from reaching theseeds. Other experiments had the box, but no fennel plant inside. In each case, the entire setup was sealedin a soundproof box to prevent outside signals from (13) . As expected, chilli seeds exposed to the fennel sprouted more slowly than when there was no fennel.Surprisingly, when the fennel was present but sealed up, those seeds sprouted fastest of all. Gaglianorepeated the experiment with 2400 chilli seeds in 15 boxes and consistently got the same result,suggesting the seeds (14) responding to a signal of some sort. She believes that this signal makesthe chilli seeds sense the (15) of chemicals that will slow their growth. Therefore, they undergo agrowth spurt. Because the box surrounding the fennel would have blocked chemical signals, Gaglianosuggests that sound may be involved.
