旁白：现在听一段生物课讲座中的一部分。

Narrator: Now listen to part of a lecture from a Biology class.

教授：好的，这是一个很好的例子，这类植物，在雨林中很常见，是瓮植物。

Professor: Okay, so a good example of this type of plant, common to the rainforest, is the urn plant.

这种瓮植物把它的根缠绕在树枝上，

The urn plant wraps its roots around the branches of the trees,

或者有时在树干上，接近树的上半部分。

or sometimes around the trunk near the upper part of the tree.

and this allows them to reside high in the trees,

在树冠中，它们可以得到充足的阳光。

in the canopy, where they can get plenty of sunlight.

这种瓮植物有一个独特的形状。

它之所以得名，是因为它的叶子形成了一种可以储存水的瓮或碗。

It got its name because the formation of its leaves creates a kind of urn or bowl where it can store water.

这个瓮的植物有很长且坚硬的叶子。

The urn plant has rather long stiff, spiky leaves.

叶子有轻微的重叠，紧紧地卷成一种锥形的形状，

The leaves are slightly overlapping and are tightly rolled into a kind of cone shape,

Its flowers are held on a single stem in the center.

树叶的在底座上排列形成了一种容器或碗，

the arrangement of the leaves forms a kind of receptacle or a bowl at the base,

它的雨水收集在树叶上，滚落到碗里，

so that its rainwater collects on the leaves, it rolls down into the bowl,

好的，它的独特形状帮助它收集和储存水。

Okay, so its unique shape helps it gather and store water.

它还能帮助收集其他营养物质。

It also helps it to gather other nutrients.

这是因为昆虫、从其他植物掉下的树叶或其他残骸落在它的叶子上，

This is because insects, dead leaves from other plants or other debris land on the leaves,

and then get washed down into the stored water.

化学分解在储存的水中产生了富含氮的食物来源。

The chemical breakdown creates a nitrogen-rich food source in the stored water.

因此，储水中含有一种液体肥料，只要它需要营养，就可以被释放到植物中。

So the water supply contains a kind of liquid fertilizer that can be released to the plant whenever it needs the food.

Epiphytes

In rain forests, the canopy produced by the upper layer of branches may be so dense that few plants can grow on the shady ground below. Even so, many plants have adapted to life in the rain forest, developing fascinating strategies for survival. For example, various species known as epiphytes use a host plant as a platform for growth. Although epiphytes grow on a host tree, they take no nutrients from the tree itself. Attached to the tree, sometimes 30 or 40 meters high, these aerial plants have access to sunlight but not to nutrients from the soil below. As a result, they have developed unusual mechanisms that have allowed them to overcome this problem.

Using the example of the urn plant, explain how epiphytes have adapted to life in the rain forest.
