1. 听写包答案：

Listen to part of a lecture in a botany class.

Professor: When we talk about pollination ecology, we are talking about the relationship between a plant and its pollinator.

From the plants' perspective, the ideal pollinator is an animal that is under-fed, ready to eat and in a hurry.

The pollinator, on the other hand, wants to remain well-fed with as little effort as possible.

These factors help drive the evolution of plants and their pollinators, both of which depend on this balanced and delicate relationship.

Sometimes only certain insects or birds can pollinate certain plant species.

So to really understand pollination ecology, both the flower and its pollinators must be studied.

Let's start with flowers.

There are several important factors associated with pollination: when and how often a plan flowers, how long the flowering cycle lasts, and the number of flowers that open at the same time.

For example, flowering may coincide with the migration of a certain animal species that pollinates the plant, or producing many flowers at once may increase the number of pollinators a plant attracts.

Other characteristics of flowers are also important.

Features such as color, scent and shape attract pollinators, as does the reward in the flower, the pollen or the nectar, that feeds the pollinator.

For example, flowers that attract bats tend to be green or cream-colored, because visibility is important.

Bats are practically blind, remember.

And these flowers bloom at night when bats are active.

Now, there's a flower in the Amazon rainforest called a royal water lily and the characteristics of its flowers change during the pollination process.

The royal water lily uses color, temperature and scent to attract the beetles that pollinate it.

When the flowers of the royal water lily first open up, when they first bloom, they are white.

They also emit a strong odor and their temperature rises.

Producing heat serves two purposes.

It magnifies the scent of the flower and it helps the beetles maintain their body temperature.

When a beetle arrives at the flower, the flower closes around it for about 24 hours so that the beetle becomes covered with pollen.

Then when the flower opens, its color changes to red and it cools down.

When the beetle flies out, it carries the pollen to a different, heated, white, fragrant flower.

As you can see, plants go to a lot of trouble to attract attention.

听一段植物学课程。

教授：当我们提到授粉生态学，我们谈论的是植物和传粉者之间的关系。

从植物的角度来说，理想的传粉者是一种饥饿的动物，准备好饱餐一顿，而且时间不多。

而另一方面，传粉者希望维持在费尽可能少的力气吃饱的状态。

这些因素有助于推动植物和传粉者的进化，两者都取决于这种平衡且微妙的关系。

有时候，只有某些昆虫或鸟类才能给某些植物传粉。

要想真正了解授粉生物学，花朵和传粉者都要研究，缺一不可。

我们先讲花。

和传粉息息相关的重要因素有好几个：植物开花的时间和频率、花期有多长、同时开花的花朵数量。

举个例子，植物开花可能正好赶在某种为之传粉的动物迁徙的时候，或者，一次性开很多朵花也可能会吸引到更多的传粉者。

花朵的其它特性也很重要。

例如像是颜色、香味和形状等能吸引传粉者的特质，还有藏在花朵里的奖励，花粉或花蜜，给传粉者提供食物。

譬如，吸引蝙蝠的花朵通常是绿色或奶油色的，因为可见度很重要。

记住，蝙蝠基本上是瞎的。

这些花在晚上盛开，这时候蝙蝠很活跃。

在亚马逊森林有一种花叫王莲，它的花朵特性在传粉期间会发生改变。

王莲以颜色、温度和香味来吸引甲虫为之传粉。

当王莲最初开花时，花是白色的。

花朵还会散发出强烈的香气，温度也会上升。

制造热量有两个目的。

它（制造热量）能把花朵香气变得更浓烈，也有助于甲虫维持体温。

当一只甲虫落到花朵上时，该花朵会闭合24小时，就能让甲虫身上覆满花粉了。

接着当花朵打开时，颜色就会变为红色，温度下降。

甲虫飞出来时，它会把花粉带到另一朵温度较高的、白色的芬芳的花朵上去。

正如你所见，植物花费不少精力来吸引（传粉者）注意。

3.写作包答案：

In modern times, Asia experienced twists and turns in its development. To change their destiny, the people of Asia have been forging ahead in an indomitable spirit and with hard struggle. Asia's development achievements today are the result of the persistent efforts of the industrious and talented Asian people.　　The people of Asia are fully aware that there is no ready model or unchanging path of development that is universally applicable. They never shy away from reform and innovation. Instead, they are committed to exploring and finding development paths that are in line with the trend of the times and their own situations, and have opened up bright prospects for economic and social development.
