你知道吗？家里的花花草草也会喊疼呢！

为了保护动物而抵制肉食的素食者们，可曾想过植物也怕疼吗？近日一项惊人的研究发现指出，植物在缺水以及被切开时会发出超声波“惨叫声”。知道这个事实后，你还能心安理得地采花摘果吗？

We always think that it’s ok for us to leave our plants unattended during our vacation as we believe that they’ll survive just fine. Plus, plants won’t scream like pets, so they must be okay, right?

我们始终认为在度假期间让植物无人看管也无所谓，因为我们认为它们自己可以照常生存下去。再说植物也不会像宠物一样尖叫，所以它们一定还好，难道不是吗？

你知道吗？家里的花花草草也会喊疼呢！1

A recent study done by a group of scientists at the Tel Aviv University has discovered that some plants will scream in a high frequency when they are undergoing stress.

还真不是。事实上，一项由以色列特拉维夫大学的科学家团队主导的最新研究发现：某些植物在承受压力时会发出高频率尖叫。

The research was carried out on tomato plants and tobacco plants by cutting their stems and depriving them of water. A microphone is placed 10cm away from the setup.

在研究中，他们或是切开番茄植株和烟草植株的茎部，或是剥夺其水分，同时将一个麦克风放置在距离实验装置10厘米的地方。

When they started cutting the stems, they found out that the plants started ‘screaming’ between 20 and 100 kilohertz and they believe that this scream is probably meant to warn other plants and organisms nearby.
