In fact trees and planting of various kinds can be used to make city streets actually less dangerous in particular areas.
事實(shí)上，在市內(nèi)特定的區(qū)域，樹木和各類植被能使城市路面危險(xiǎn)度降低一些。
How do trees do all that, you ask?
樹木是如何做到這些的呢？
Well, the main difference between a tree and a building is a tree has got an internal mechanism to keep the temperature regulated.
嗯，樹木和建筑最主要的區(qū)別是樹木自身的內(nèi)部機(jī)制能調(diào)節(jié)溫度。
It evaporates water through its leaves and that means that the temperature of the leaves is never very far from our own body temperature.
水分通過樹葉蒸發(fā)，這意味著樹葉的溫度不會(huì)和人類的體溫相差太遠(yuǎn)。
The temperature of a building surface on a hot sunny day can easily be twenty degrees more than our temperature.
艷陽(yáng)炙烤下的建筑物表面溫度輕易就能超過體溫20度。
Trees, on the other hand, remain cooler than buildings because they sweat.
而另一方面，樹木能持續(xù)保持比建筑物溫度低，因?yàn)樗麄兡艹龊埂?/div>
This means that they can humidify the air and cool it - a property which can be exploited to improve the localclimate.
這就意味這他們能濕潤(rùn)空氣，然后降溫，而這個(gè)特質(zhì)能被用于改善本地氣候。
