【分析】
做语法填空时，需先通读短文理解主旨（英国孩子对食物来源认知的调查），再逐空结合语法规则和语境分析：1. 句子描述过去的调查结果，需用动词过去式；2. 与clerks并列，需用名词复数；3. 修饰人用ed结尾的形容词，搭配固定短语be surprised at；4. 固定搭配“在农场”用介词on；5. 询问来源用疑问词where；6. 泛指一项研究，用不定冠词A；7. 固定短语turn into表“变成”；8. 由than判断用比较级；9. 固定句型it's necessary to do sth；10. 修饰名词用形容词性物主代词。
【解析】
1. 句子描述过去发生的调查结果，用一般过去时，show的过去式为showed；
2. volunteer是可数名词，与clerks并列，需用复数形式volunteers；
3. 主语为指代人的they，be surprised at是固定搭配，故填surprised；
4. “在农场”的固定表达为on farms，故填on；
5. 句意是“不知道牛奶来自哪里”，表来源用疑问词where；
6. study是可数名词单数，此处泛指“一项研究”，且以辅音音素开头，故用不定冠词A；
7. turn into是固定短语，意为“变成”，故填into；
8. 由句中than可知需用比较级，much的比较级为more；
9. it's necessary to do sth是固定句型，意为“做某事是必要的”，故填to teach；
10. 修饰名词food，需用形容词性物主代词their。
【答案】1. showed 2. volunteers 3. surprised 4. on 5. where 6. A 7. into 8. more 9. to teach 10. their
