新素材 长颈鹿的数学智慧 As a large mammal (哺乳动物), the giraffe has quite a small brain. However, a new study shows that giraffes are smarter than we thought. 1
Four giraffes at the Barcelona Zoo in Spain took part in some experiments (实验). The scientists showed the animals two transparent(透明的) boxes. Each box was filled with sticks of carrot and zucchini (密生西葫芦). 2 Giraffes love carrots but are not very interested in zucchinis.
In the first experiment, the scientists took a vegetable stick from each box. 3 The giraffes didn't see which vegetables had been picked up. Guess which one they chose? The stick taken from the box with more carrots than zucchinis!
4 The giraffes could only see the top part of the boxes. Still, they made the same choice. What does this mean? Well, the giraffes were able to not only choose the box with the most carrots, but also make their decisions based on ratios(根据比例).
The giraffes used maths to make predictions (预测). 5 Before this study, it had only been seen in animals with bigger brains relative to (相对于) body size. These animals include monkeys, apes(猿类) and a large parrot in New Zealand.

A. In fact, they are very good at maths.
B. And they couldn't tell the differences.
C. They held both sticks in closed fists(拳头).
D. This is a highly developed (高度发达的) thinking skill.
E. In the second experiment, a wall was placed in each box.
F. One box had more carrot sticks and the other had more zucchini sticks.
1. 2. 3. 4. 5.

【语篇解读】本文是一篇说明文。文章主要讲述了长颈鹿具有超出预期的数学能力，能够根据比例做出选择。
1. A 根据前文“However, a new study shows that giraffes are smarter than we thought.”可知，此处需要补充说明长颈鹿的聪明之处体现在哪里。选项 A“事实上，它们的数学非常好。”符合语境，故选 A。
2. F 根据前文“Each box was filled with sticks of carrot and zucchini.”以及“Giraffes love carrots but are not very interested in zucchinis.”可知，此处需要说明两个盒子的区别。选项 F“一个盒子里有更多的胡萝卜条，另一个盒子里有更多的密生西葫芦条。”符合语境，故选 F。
3. C 根据后文“The giraffes didn't see which vegetables had been picked up.”可知，此处在描述科学家取棒方式。选项 C“他们紧握双拳，手里都拿着蔬菜条。”符合语境，故选 C。
4. E 根据后文“The giraffes could only see the top part of the boxes.”可知，实验中设置了障碍物来限制长颈鹿的视线。选项 E“在第二个实验中，每个盒子里都放了一面墙。”符合语境，故选 E。
5. D 根据前文“The giraffes used maths to make predictions.”以及“it had only been seen in animals with bigger brains”可知，这种能力属于高级认知技能。选项 D“这是一种高度发达的思维能力。”符合语境，故选 D。

根据短文内容,回答问题(每题答案不超过 8 个词)。
(2025·临沂期中改编)Siberian tigers(西伯利亚虎) usually live in forests in Russia and China. They are strong, beautiful, and they are also big. Some of them are around 250 kg in weight. These tigers like to eat forest animals and they usually hunt(捕猎) at night. They are powerful hunters, but there are only about 500 left in the world. They are in great danger.
There are several reasons for this. First, some people kill the tigers for food or medicine. Second, people cut down too many trees. When the forest is cut down, lots of wild animals leave and it's difficult for them to hunt, so they get hungry and weak.
However, there is good news. People around the world want to help Siberian tigers. For example, the Northeast China Tiger and Leopard National Park helps protect them. There are cameras (摄像机) all around the forest. Scientists and other people can watch the tigers, and make sure they are safe. Park rangers(看守人) help too. They protect the animals in the park. They keep other people away from the places with the tigers and their young babies. This means the young babies can grow up safely with their mothers.
The rangers also teach people about why the tigers and forests are important. So more and more people want to protect the tigers and forests. With more trees, the tigers and their babies have more places for their homes and they also have more food. We hope there will be more Siberian tigers in the future!
1. What are Siberian tigers like?

2. When do Siberian tigers usually hunt?

3. Why are the Siberian tigers in great danger?

4. What do cameras in the national park help do?

5. What's the writer's purpose(目的) of writing the passage?

【语篇解读】本文是一篇说明文。文章介绍了西伯利亚虎的生存现状，包括它们的特征、面临的危险，以及人们为保护它们采取的措施，呼吁关注和保护西伯利亚虎与森林。
1. Strong, beautiful and big. 根据“They are strong, beautiful, and they are also big.”可知，西伯利亚虎强壮、美丽且体型庞大。
2. They usually hunt at night./At night. 根据“These tigers like to eat forest animals and they usually hunt at night.”可知，西伯利亚虎通常在夜间捕猎。
3. People kill them and cut trees. 根据“First, some people kill the tigers for food or medicine. Second, people cut down too many trees.”可知，一是人类捕杀用于食物或药材，二是砍伐树木破坏栖息地，导致它们濒危。
4. Helping watch tigers and making sure they're safe. 根据“Scientists and other people can watch the tigers, and make sure they are safe.”可知，森林四周都安装了摄像机。科学家和其他人都可以通过这些摄像机观察老虎，并确保它们的安全。
5. To call for protecting Siberian tigers. 文章讲述了西伯利亚虎濒危状况及保护措施，目的是呼吁大家保护西伯利亚虎和森林。
