(22-Book4 Unit4）The journey of discovery 发现之旅
In myths and legends, it’s the gods that created a variety of living things, including humans. However, the theory of evolution, explained by Charles Darwin in On the Origin of Species, completely changed this idea. The young man, regarded as a disgrace to his family by his father, was a geologist and naturalist. Answering the call of a captain, he visited distant countries and collected various samples, including seeds of mangroves, comb-like spines of iguanas, beaks of finches,shells of gianttortoises.
在神话和传说中，正是众神创造了包括人类在内的各种生物。然而，查尔斯·达尔文在《物种起源》中解释的进化论彻底改变了这种观念。这个曾被父亲视为家族耻辱的年轻人是一名地质学家和博物学家。响应一位船长的号召，他拜访遥远的国度，收集各种样本，包括红树的种子，鬣蜥梳状的刺，雀科鸣禽的喙，巨型陆龟的壳。
On a primitive island whichis renowned worldwide for biodiversity and which several species of goats are native to, Darwin suspected that theirteeth evolved according to what food was available, generating the convincing idea that they had evolved from a common ancestor with unique physical characteristics, and that their population decline is blamed on humans.
在一座因生物多样性而全世界闻名的原始岛屿上，有几种山羊原生于此，达尔文怀疑他们牙齿根据可获得的食物而进化，并产生了一种令人信服的看法：他们都从带有独特身体特征的共同祖先进化而来，并且种群数量的下降应被归咎于人类。
（选背1： Though Darwin’s journey of discovery had ended, diversity on our planet is such that there are still new species and characteristics on Earth remaining to be discovered. For instance, with us long believing that talking plants have been a thing of myths and legends, new research has revealed something amazing: it appears that plants can communicate after all.
尽管达尔文的发现之旅已经结束，我们星球上的多样性是如此丰富，以至于在地球上依然有新的物种和特征等待着我们去发现。比如，我们一直认为会说话的植物只存在于神话传说中，但新研究揭示了令人惊奇的事实：植物间似乎确实可以交流。）
This kind of communication happens when a plant, say a chilli plant, gets attacked by insects. The plant can release chemicals detected by its neighbors, who give off different chemicals to attract wasps to drive away the insects, so that we needn’t pesticides. More surprisingly, around 50 centimetres underground, the roots of all chilli plants are linked by fungi to form a fungal network, which has its own version of cybercrime.
当一株植物，比如说一棵辣椒树，受到昆虫攻击时，这种交流就会发生。这棵辣椒会释放出能被周围其他辣椒探测到的化学物质，他们会释放不同的化学物质来吸引黄蜂赶走昆虫，因此我们不需要杀虫剂。更不可思议的是，在地下大约50分米处，所有辣椒树的根通过真菌连接成了一个真菌的网络，这种网络也有（植物世界里的）“网络犯罪”。
（选背2： Again for instance, by examining preserved bodies and fossils, scientists have identified bacteria helping with digestion, fungi breaking down dead organic matter and viruses harmful to human immune systems. By doing research on hybrid rice, researchers have developed better types of rice adapting to terrible environment, which can survive temperatures from 50℃ to a below freezing -50℃.
再比如，通过检查保存下来的尸体和化石，科学家们已经发现了促进消化的细菌，能分解死亡有机物的真菌，以及伤害人体免疫系统的病毒。通过研究杂交水稻，研究者们已经研发出了适应恶劣环境的更优品种的水稻，可以在50℃到-50℃的温度下生存。)
