【分析】
本题为英语语法填空与词汇拓展题，解题思路如下：1. 语法填空需结合句子结构、时态标志、词性转换、固定搭配、从句引导等知识点，逐个分析每个空格的语法要求和语境含义，确定正确形式；2. 词汇拓展需结合上下文语境判断单词的词性和含义。具体步骤：先通读短文理解大意，再针对每个空的语法需求推导答案，最后判断拓展单词的词性与意思。
【解析】
1. 空格后是名词stories，需用名词所有格作定语，children的所有格为children's，符合“孩子们的故事”的语境。
2. so far是现在完成时的标志，主语a recent study为单数，故谓语用has found。
3. 此处需副词修饰整个句子，actual的副词形式是actually，意为“实际上”。
4. 固定搭配too...to...表示“太……而不能……”，故填to hear。
5. 句中出现than，需用many的比较级more，意为“更多的”。
6. 固定搭配between...and...表示“在……和……之间”，符合“干旱植物与被切断植物的差异”的语境。
7. 结合句意“当/如果压力原因改变时，它们的呼喊不同”，用连词when或if引导条件/时间状语从句。
8. 此处特指前文提到的研究团队，用定冠词the。
9. 同位语从句解释possibility的内容，用that引导，无实义。
10. other后接可数名词复数，plant的复数形式为plants。
词汇拓展：pitch在此处为名词，结合语境（声音的相关属性），意思是“音高”。
