【分析】
本题为语法填空题，需结合固定搭配、语法规则、语境等逐一分析每个空：1. 看到动词need，回忆其固定搭配need to do sth确定25空；2. there be句型遵循主谓一致，根据主语单复数确定26空；3. 句首Look提示动作正在进行，用现在进行时结构确定27空；4. 结合语境选表“通过”的介词确定28空；5. 固定搭配mix...and...确定29空；6. 修饰整个句子需用副词确定30空；7. 定冠词the后接名词，转换词性确定31空；8. human表“人类”常用复数确定32空；9. 固定短语take a rest确定33空；10. 修饰名词world需用形容词，转换词性确定34空。
【解析】
25. 考查固定搭配need to do sth，意为“需要做某事”，故填to start。
26. 考查there be句型的主谓一致，主语为复数名词20 to 100 workers，句子为一般现在时，be动词用are。
27. 考查现在进行时，由句中“Look!”可知动作正在进行，结构为“be + 现在分词”，故将send变为sending。
28. 考查介词，此处表示“水通过茎上升”，through表示“（从内部）穿过、通过”，符合语境。
29. 考查固定搭配mix...and...，意为“把……和……混合”，故填and。
30. 考查副词，此处修饰整个句子，需用important的副词形式importantly。
31. 考查名词，定冠词the后接名词，grow的名词形式为growth，意为“生长”。
32. 考查名词复数，human为可数名词，此处与animals并列表“人类”，用复数humans。
33. 考查固定短语take a rest，意为“休息”，故填不定冠词a。
34. 考查形容词，此处修饰名词world，需用nature的形容词形式natural，意为“自然的”。
