第二节 请认真阅读下面短文，从短文后所给的六个选项中选出五个可以填入空白处的最佳选项。
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. 41.
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). 42.
In the first experiment, the scientists took a vegetable stick from each box. 43.
44.
The giraffes used maths to make predictions(预测). 45.
A. In fact, they are very good at maths.
B. And they couldn't tell the differences.
C. This is a highly developed thinking skill.
D. They held both sticks in closed fists(拳头).
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.

A
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). 42.
F
Giraffes love carrots but are not very interested in zucchinis.In the first experiment, the scientists took a vegetable stick from each box. 43.
D
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!44.
E
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). 45.
C
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. This is a highly developed thinking skill.
D. They held both sticks in closed fists(拳头).
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.

解析
【分析】
做英语七选五题型时，需先通读全文把握主旨（本文围绕长颈鹿具备超出预期的数学能力展开），再结合每个空白处的前后句，通过逻辑关系、关键词呼应、上下文衔接等线索逐一确定选项：首段引出长颈鹿比想象中聪明，41题需承接“聪明”并引出实验相关内容；42题对应前文“两个装不同蔬菜的盒子”；43题解释长颈鹿看不到所选蔬菜的原因；44题引出第二个实验的设置；45题承接前文长颈鹿的数学能力，引出下文对该能力的评价。
【解析】
1. 41题：前文提到“长颈鹿比我们想的聪明”，A选项“事实上，它们很擅长数学”既承接上文的“聪明”，又引出后文的实验内容，符合逻辑，故选A。
2. 42题：前文提到“两个装胡萝卜和西葫芦的透明盒子”，F选项“一个盒子有更多胡萝卜条，另一个有更多西葫芦条”具体说明两个盒子的内容，与前文呼应，故选F。
3. 43题：前文提到“科学家从每个盒子各取一根蔬菜条”，后文提到“长颈鹿没看到选的是哪根”，D选项“他们把两根棍子握在闭合的拳头里”解释了长颈鹿看不到的原因，衔接自然，故选D。
4. 44题：后文提到“长颈鹿只能看到盒子顶部”，说明是第二个实验的设置，E选项“第二个实验里每个盒子放了一堵墙”引出第二个实验，符合上下文顺序，故选E。
5. 45题：前文提到“长颈鹿用数学做预测”，后文提到“这种能力之前只在大脑更大的动物中发现”，C选项“这是一种高度发达的思维技能”承接前文的能力，引出下文的对比，故选C。
【答案】
AFDEC
【知识点】
英语七选五阅读，语篇逻辑衔接，说明文阅读
【点评】
本文是介绍长颈鹿数学能力的说明文，解题需关注上下文的逻辑关系、实验的顺序及内容呼应，属于常规难度的七选五题型，能较好考查学生的语篇理解和逻辑推理能力。
