摘要：植物在承受压力时会发出声音——而某些动物能对这些声音做出反应。这是特拉维夫大学研究人员一项新研究中得出的惊人结论。他们发现，雌蛾会避免在番茄植株上产卵，因为这些植株会发出与困境相关的超声波。

今天我们将学到下列词汇和表达，大家看看已经掌握了多少：

Plants make sounds when they’re stressed— and some animals respond to them. That’s the surprising conclusion of a new study by researchers at Tel Aviv University, who found that female moths avoided laying eggs on tomato plants that were emitting ultrasonic noises associated with distress.

植物在承受压力时会发出声音——而某些动物能对这些声音做出反应。这是特拉维夫大学研究人员一项新研究中得出的惊人结论。他们发现，雌蛾会避免在番茄植株上产卵，因为这些植株会发出与困境相关的超声波。

It may be, the researchers say, that the insects interpreted the sounds as a sign the plants were unhealthy. The same team had previously shown that plants “scream” when under stress from drought or physicaldamage, emitting high-frequency noises.

研究人员表示，昆虫可能将这些声音解读为植株不健康的信号。该团队先前已证明，植物在遭受干旱或物理损伤的压力时会发出高频噪音，如同"尖叫"。

The sounds are undetectable to human ears, but many animals, including insects, bats, and rodents, can hear them. “This is the first demonstration ever of an animal responding to sounds produced by a plant,” co-author Yossi Yovel says.

这种声音人耳无法察觉，但许多动物（包括昆虫、蝙蝠和啮齿动物）都能听到。"这是首次有研究证实动物会对植物产生的声音做出反应，"论文合著者约西·约维尔表示。

The finding raises the possibility that other species use plant noises to guide decisions about feeding, pollination, or shelter. “This is speculation at this stage,” says Yovel, “but it could be that all sorts of animals will make decisions based on the sounds they hear from plants.”

这一发现提出了新的可能性：其他物种可能会利用植物发出的声音来指导觅食、授粉或栖居决策。"目前这还只是推测，"约维尔说，"但很可能各种动物都会根据从植物处听到的声音来做出决策。"
