On a hot afternoon, people sweat and feel hot, and muscles can heat up after exercise. They hurry to rest in the shade, drink boiled water, or eat an ice cream, and gradually feel cooler as moisture returns to the mouth. These common facts are easy to understand, but plants have no sweat glands or pores that open like ours.
不过，叶片并不是完全安静的。叶子表面有许多细小开口，叫作气孔，水分会慢慢冒出；这叫蒸腾。它不是像人一样主动流汗，而是植物内部系统自动调节的一部分。风吹过叶面时，这个过程还会更明显。
bù guò， yè piàn bìng bù shì wán quán ān jìng de。 yè zi biǎo miàn yǒu xǔ duō xì xiǎo kāi kǒu， jiào zuò qì kǒng， shuǐ fēn huì màn màn mào chū； zhè jiào zhēngténg。 tā bù shì xiàng rén yī yàng zhǔ dòng liú hàn， ér shì zhí wù nèibù xìtǒng zìdòng diào jié de yī bù fēn。 fēng chuī guò yè miàn shí， zhè gè guò chéng hái huì gèng míng xiǎn。
Yet a leaf is not completely quiet. Its surface has many tiny openings called stomata, from which water slowly emerges; this is called transpiration. It is not active sweating like a person's, but part of an automatic adjustment in the plant's internal system. When wind passes over a leaf, the process can become more obvious.
根从土壤吸收水和矿物成分，水再沿着像管子的组织上升，经过茎、枝干和嫩梢，最后到达每一片叶。这个过程好像有人在指挥，却没有一个真正的指挥者；根本原因在于植物内部不断流动的水分。白天光线变化时，叶片上气孔的开合也会随之调整。

Roots absorb water and mineral components from soil. The water then rises through tube-like tissue, passing through the stem, branches and tender tips until it reaches every leaf. The process seems directed by someone, yet has no real commander; its fundamental cause is the water moving continuously inside the plant. As daylight changes, the stomata on leaves adjust their opening and closing as well.

Scientists can do a simple test: put a leafy branch into a glass bottle of water and place a little oil on the surface. After some time, the water still decreases, showing that the plant draws it up and releases it from the leaf into the air.
蒸腾有特殊作用。天气太热时，它能帮助叶子降温；水分不够时，植物也会控制开口，尽量少失去水。不同植物的状况不一样，沙漠植物和水边植物的办法当然不同。
zhēngténg yǒu tèshū zuò yòng。 tiān qì tài rè shí， tā néng bāng zhù yè zi jiàng wēn； shuǐ fēn bù gòu shí， zhí wù yě huì kòngzhì kāi kǒu， jǐn liàng shǎo shī qù shuǐ。 bù tóng zhí wù de zhuàngkuàng bù yī yàng， shā mò zhí wù hé shuǐ biān zhí wù de bàn fǎ dāng rán bù tóng。
Transpiration has special functions. In very hot weather it can help leaves cool down; when water is scarce, a plant can also control its openings to lose as little water as possible. The condition of each plant differs, so desert and waterside plants naturally use different methods.
因此，植物并非只是被天气摆布。它们依靠内部水分循环的秩序不断补充和调整，在没有脚和嘴的条件下维持生命。看见一片叶子安静地蒸腾，我们就能想到一套复杂而有效的系统，也能理解生命如何在无声处合作。
yīn cǐ， zhí wù bìng fēi zhǐ shì bèi tiān qì bǎi bù。 tā men yī kào nèibù shuǐ fēn xún huán de zhìxù bù duàn bǔchōng hé diào zhěng， zài méi yǒu jiǎo hé zuǐ de tiáo jiàn xià wéi chí shēng mìng。 kàn jiàn yī piàn yè zi ān jìng dì zhēngténg， wǒ men jiù néng xiǎng dào yī tào fù zá ér yǒu xiào de xìtǒng， yě néng lǐ jiě shēng mìng rú hé zài wú shēng chù hé zuò。
Plants are therefore not merely controlled by weather. They rely on the ordered circulation of internal water to replenish and adjust continuously, sustaining life without feet or mouths. Seeing a leaf quietly transpire can make us think of a complex and effective system, and of how life cooperates in silence.

植物的功能 - Functions of Plants
Plants provide oxygen, food, and habitats. Roots absorb water, leaves use sunlight to make nutrients, and plants can hold soil in place. City trees bring shade and improve the environment. Understanding these functions can make people more willing to protect green life.
