经典电影台词——The Shawshank Redemption《肖申克的救赎》
You know some birds are not meant to be caged. Their feathers are just too bright.
你知道,有些鸟儿是注定不会被关在牢笼里的。它们的每一片羽毛都闪耀着自由的光辉。

Stopping illegal wildlife trade is hard. People who sell or buy these products illegally often hide them in special ways. They might paint an elephant tusk black. They might hide the products in a false bottom in a box.
Something such as coffee has strong smells.
A group called APOPO thinks that African giant pouched (有袋的) rats might be able to help. African giant pouched rats are the largest rats in the world. They are up to three feet long, and weigh about three pounds.
These rats are clever. They learn quickly, and have a strong sense of smell. In the past, these rats were used to help search for people after earthquakes. Now, the rats are trained with food rewards.
The results suggest that these clever, coat-wearing rats could be an important tool in the fight against illegal wildlife trade.

A. Their name comes from the special bags.
B. More pouched rats are serving for humans.
C. They are first taught to put their noses into a hole.

F. But the method could help protect some endangered animals.

2 Something such as coffee has strong smells.A group called APOPO thinks that African giant pouched (有袋的) rats might be able to help. African giant pouched rats are the largest rats in the world. They are up to three feet long, and weigh about three pounds.
A
3 They are on either side of the face, below the eye. They store food there.These rats are clever. They learn quickly, and have a strong sense of smell. In the past, these rats were used to help search for people after earthquakes. Now, the rats are trained with food rewards.
C
4 Next, the scientists train them to recognise certain smells. Finally, the rats are taught about smells they should take no notice of.D
5 If the rat discovers one of the smells it's looking for, it catches a little ball on its coat and pulls on it. This action sets off a sound so that the rat's trainers can come to check.The results suggest that these clever, coat-wearing rats could be an important tool in the fight against illegal wildlife trade.

解析
【分析】
做信息还原类的七选五题目时，首先要通读全文，掌握文章主旨（本文围绕坦桑尼亚训练巨囊鼠寻找非法野生动物产品展开），接着分析每个空格前后的语境，结合转折、顺承、指代等逻辑关系匹配选项，最后将所选选项代入原文，检查语句是否通顺、逻辑是否连贯。
【解析】
1. 第1空：前文提到训练老鼠找非法野生动物产品的项目仍在测试，后文需转折说明该项目的价值，选项F“但该方法可帮助保护一些濒危动物”承接前文的“仍在测试”，转折体现项目意义，符合语境。
2. 第2空：前文讲述非法交易者隐藏野生动物产品的方式，后文提到用咖啡等强气味掩盖，选项G“他们常常使用其他东西掩盖这些产品的气味”衔接前后，解释了掩盖气味的具体做法，对应后文的强气味掩盖，逻辑通顺。
3. 第3空：前文介绍非洲巨囊鼠，后文提到其脸部两侧眼睛下方的特殊袋子，选项A“它们的名字来自这些特殊的袋子”承上启下，解释了“巨囊鼠”名称的由来，与后文对袋子的描述呼应。
4. 第4空：前文说明用食物奖励训练老鼠，后文提到“接下来”训练识别特定气味，选项C“首先教它们把鼻子放进洞里”是训练的第一步，与后文的“接下来”“最后”构成顺承的训练步骤，符合逻辑。
5. 第5空：后文讲述老鼠发现目标气味后的动作（拉小球触发警报），选项D“当老鼠工作时，穿特殊的外套”引出工作时的装备，为后文的动作做铺垫，上下文连贯。
【答案】
1.F 2.G 3.A 4.C 5.D
