You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

题目解答
答案
### 解析
1. **26题**：根据上下文，这里需要一个动词来表示“新的研究揭示了……”。因此，选择 **L) revealed**。
- **解析**：这句话的意思是“来自马里兰大学的生物学家的新研究揭示了视觉剥夺也会改变脑细胞之间的相互作用方式”。
2. **27题**：这里需要一个动词来描述脑细胞之间的相互作用。因此，选择 **D) interact**。
- **解析**：这句话的意思是“视觉剥夺也会改变脑细胞之间的相互作用方式，改变老鼠对不同频率的敏感度”。
3. **28题**：这里需要一个动词来表示“这项研究强化了我们对……的了解”。因此，选择 **K) reinforces**。
- **解析**：这句话的意思是“这项研究强化了我们对如何通过操纵视觉来对动物的听觉能力产生长期影响的了解”。
4. **29题**：这里需要一个形容词来描述影响的程度。因此，选择 **M) significant**。
- **解析**：这句话的意思是“这项研究强化了我们对如何通过操纵视觉来对动物的听觉能力产生显著长期影响的了解”。
5. **30题**：这里需要一个动词来表示“关闭”。因此，选择 **B) closed**。
- **解析**：这句话的意思是“这项研究强化了我们对如何通过操纵视觉来对动物的听觉能力产生显著长期影响的了解，即使在听觉学习的窗口期被认为已经关闭之后”。
6. **31题**：这里需要一个形容词来描述大脑的可塑性。因此，选择 **A) adaptable**。
- **解析**：这句话的意思是“人们曾经认为，大脑的感官区域在儿童时期的某个关键期之后就不再具有可塑性”。
7. **32题**：这里需要一个副词来描述儿童学习语言的速度。因此，选择 **I) readily**。
- **解析**：这句话的意思是“这就是为什么儿童比成人更容易学习语言”。
8. **33题**：这里需要一个形容词来描述频率的特定性。因此，选择 **N) specific**。
- **解析**：这句话的意思是“年轻的大脑会根据它们经常听到的声音来布线，将听觉皮质的区域分配给特定的频率”。
9. **34题**：这里需要一个名词来描述频率的分布。因此，选择 **C) distribution**。
- **解析**：这句话的意思是“研究人员发现，在成年老鼠中，一周的黑暗也改变了对不同频率的空间分布”。
10. **35题**：这里需要一个动词来表示“推测”。因此，选择 **O) speculate**。
- **解析**：这句话的意思是“我们不知道为什么我们会看到这些模式，我们推测这可能与老鼠在黑暗中注意的事情有关”。
