Question

    If you’ve been paying attention, you know that crows (乌鸦) are remarkably intelligent birds. 1.: six crows have been trained to pick up rubbish in the Puy du Fou historical theme park in western France. 2., it dispenses (分发) a treat to reward the crows for their efforts.

The idea came from one of the park’s falconers (放鹰员), Christophe Gaborit. As part of the falconry show, crows had already been trained to pick up roses and bring them to a princess. So in the 2000s, Gaborit raised and trained two crows to do the same with rubbish. 3., in which a dispenser gives a food reward when a crow correctly performs a task.

Earlier this year, we saw research in which a type of “vending machine” was used to teach crows how to tear paper into a specific shape. And 10 years ago, “hacker” Josh Klein built a similar vending machine to reward crows for getting back lost money. 4..

The crows were used for the first time over the weekend, and they'll be working four days a week under close watch —not for the birds, but to make sure the humans don’t deliberately drop rubbish to watch the birds clean it up.

That's because the aim of the crow garbage collectors isn't merely to collect garbage—it's also to get park-goers to think before they litter. 5..

A.So we know the concept works

B.But bird lovers have different views

C.Now these feathered talents have been given a job

D.The crows are trained to identify small pieces of rubbish

E.Whenever they put a small piece of rubbish in a special container

F.It’s a funny way to show the people that you cannot throw the papers everywhere

G.The training system is similar to experimental setups for testing crows’ intelligence

Answer

【解析】

这是一篇说明文。全文主要介绍了法国西部的Puy du Fou历史主题公园训练乌鸦捡垃圾，并通过这种方式呼吁游客不要随处扔垃圾。

1.

根据后文“six crows have been trained to pick up rubbish in the Puy du Fou historical theme park in western France.”在法国西部的Puy du Fou历史主题公园，训练了六只乌鸦捡垃圾。C项“Now these feathered talents have been given a job.”现在这些带羽毛的天才被分配了一份工作。与后句中的“have been trained to pick up rubbish”相呼应。故选C项。

2.

根据前文“six crows have been trained to pick up rubbish in the Puy du Fou historical theme park in western France.”在法国西部的Puy du Fou历史主题公园，训练了六只乌鸦捡垃圾。E项“Whenever they put a small piece of rubbish in a special container”每当他们将一小块垃圾放在一个特殊的容器中时。与前文中的“pick up rubbish”相呼应，切合题意。故选E项。

3.

根据上文“it dispenses (分发) a treat to reward the crows for their efforts.”给乌鸦分配奖励来奖励乌鸦的努力。G项“The training system is similar to experimental setups for testing crows’ intelligence”训练系统类似于用于测试乌鸦智力的实验装置。与上文“it dispenses (分发) a treat to reward the crows for their efforts.”形成平行结构，符合本段语境。故选G项。

4.

根据前文“Earlier this year, we saw research in which a type of “vending machine” was used to teach crows how to tear paper into a specific shape.” 今年早些时候，我们看到了一项研究，其中使用一种“自动售货机”来教乌鸦如何将纸张撕成特定的形状。以及“And 10 years ago, “hacker” Josh Klein built a similar vending machine to reward crows for getting back lost money.”10年前，“黑客”Josh Klein建造了类似的自动售货机，用以奖励乌鸦找回损失的钱。可知十年前的概念在如今已经成为现实。A项“So we know the concept works”因此我们知道这个概念已经起作用了。对本段前文起到总结作用。故选A项。

5.

根据前文“it's also to get park-goers to think before they litter.”这也可以让公园游客在乱扔垃圾之前思考一下。F项“It’s a funny way to show the people that you cannot throw the papers everywhere”这是一种有趣的方式，向人们表明不能到处扔纸。与前文litter“扔垃圾”相呼应。故选F项。
