(2025·厦门二模) Most people use one hand more than the other, like being right-handed or left-handed. Surprisingly, elephants also have a preferred side for using their trunks! German scientists studied this by watching Asian and African elephants in zoos and wildlife parks. They spent months recording how elephants used their trunks to pick up food, drink water, and play with objects.
How did they discover an elephant's "favourite side"? The answer lies in the wrinkles(皱纹) on their trunks. The team discovered that the wrinkles on an elephant's trunk are not the same on both sides. For example, some elephants are left-trunkers. These elephants pick up objects towards the left side of their bodies. So, their trunks have more wrinkles on the left side.
Interestingly, Asian and African elephants showed differences. Asian elephants' trunks have more wrinkles than African elephants'. More wrinkles make trunks more flexible, similar to how folds in an accordion(手风琴) work. This might explain why Asian elephants' trunks bend(弯曲) more easily. Another key difference is the end of the trunk. African elephants have two finger-like parts at the trunk's end, allowing them to scoop objects like humans using two fingers. Asian elephants, however, have only one "finger", so they depend on their highly wrinkled trunks to lift up things.
Why do these differences matter? Scientists believe Asian elephants need more wrinkles to help them collect food in the forests where they live, while African elephants' double "fingers" work better for getting objects on the open grasslands. This study shows how animals' bodies get used to their environments. Next time you see an elephant, look closely—its trunk wrinkles might tell you whether it's a "left-trunker" or a "right-trunker"!

答案:1 - 5 AACDD
【语篇解读】本文是一篇说明文,主要介绍了专家研究发现大象使用象鼻有偏好,这种偏好与大象的种类及生存环境有关。
1. A 解析:写作手法题。根据第一段开头“Most people use one hand more than the other,like being right - handed or left - handed.”可知,第一段开头介绍了“大多数人用一只手比用另一只手多,比如右撇子或左撇子”的情况,即作者通过讲述事实的方式开启了本文。故选 A。
2. A 解析:段落大意题。通读第二段尤其是“How did they discover an elephant's ‘favourite side’?”可知,第二段主要在讲述专家是如何发现大象的偏好的,选项 A“大象习性的发现”符合。故选 A。
3. C 解析:词义猜测题。根据第三段“More wrinkles make trunks more flexible,similar to how folds in an accordion work. This might explain why Asian elephants' trunks bend more easily.”中的“bend more easily”可知,大象的褶皱类似于手风琴的褶皱,使得亚洲象的鼻子更容易弯曲,由此推测画线词应指“容易弯曲的”,与选项 C“可弯曲的”的意思相近。故选 C。
4. D 解析:细节理解题。根据第三段“Asian elephants' trunks have more wrinkles than African elephants'.”及“African elephants have two finger - like parts at the trunk's end”可知,在非洲象的鼻上,可以发现较少的皱纹,并且能看到两个类似手指的结构,因此②④表述正确。故选 D。
5. D 解析:主旨大意题。通读全文可知,本文主要介绍了专家研究发现大象使用象鼻有偏好,这种偏好与大象的种类及生存环境有关,因此选项 D“为了展示大象在自身所处环境中身体结构的适应性情况”符合。故选 D。

(2025·厦门二模)大多数人使用一只手多于另一只手,比如习惯用右手或左手。令人惊讶的是,大象使用象鼻时也有偏好的一侧!德国科学家通过观察动物园和野生动物园里的亚洲象和非洲象来研究这一现象。他们花了数月时间记录大象如何用象鼻拾取食物、喝水以及摆弄物体。
他们是如何发现大象的“偏好侧”的呢?答案在于象鼻上的皱纹。研究团队发现,大象象鼻两侧的皱纹并不相同。例如,有些大象是“左象鼻使用者”。这些大象会朝着自己身体的左侧拾取物体。因此,它们的象鼻左侧有更多皱纹。
有趣的是,亚洲象和非洲象呈现出差异。亚洲象的象鼻皱纹比非洲象的更多。更多的皱纹使象鼻更具柔韧性,这类似于手风琴的褶皱的作用原理。这或许可以解释为什么亚洲象的象鼻更容易弯曲。另一个关键差异在于象鼻的末端。非洲象的象鼻末端有两个手指状的部分,这使它们能够像人类用两根手指那样舀取物体。然而,亚洲象只有一个“手指”,所以它们依靠高度起皱的象鼻来举起物体。
这些差异为什么重要呢?科学家认为,亚洲象需要更多皱纹来帮助它们在栖息的森林中采集食物,而非洲象的两个“手指”更适合在开阔的草原上获取物体。这项研究展示了动物的身体是如何适应其生存环境的。下次你看到大象时,仔细观察——它的象鼻皱纹可能会告诉你它是“左象鼻使用者”还是“右象鼻使用者”!
