解析
【分析】
先通读短文，理解关于紫色西红柿的介绍内容，再逐个分析每个空格的考点：结合语境、语法规则（如被动语态、比较级、时态）、固定搭配、词性变化等确定答案。
1. 36题：考查情态动词的被动语态，主语purple tomato与sell是被动关系，情态动词could后接be+过去分词；
2. 37题：考查形容词比较级，句中出现than，需用great的比较级；
3. 38题：考查宾语从句引导词，根据句意“是否能培育出...”，需填表“是否”的引导词；
4. 39题：考查情态动词用法，could后接动词原形；
5. 40题：考查固定搭配，test sth on sb表示“在某人身上测试某物”；
6. 41题：考查固定搭配a piece of，good以辅音音素开头，用不定冠词a；
7. 42题：考查名词复数，此处指“人类”，需用human的复数形式；
8. 43题：考查副词用法，修饰动词sell，需用wide的副词形式；
9. 44题：考查代词，指代前文的teammates，需用人称代词主格；
10. 45题：考查现在完成时，so far是现在完成时的标志，主语是they，需用have+过去分词。
【解析】
36. 情态动词could后接动词原形，主语purple tomato与sell是被动关系，故填be sold；
37. 句中出现than，形容词需用比较级，故填greater；
38. 此处引导宾语从句，表“是否”，故填if/whether；
39. 情态动词could后接动词原形，故填stay；
40. 固定搭配test sth on sb，故填on；
41. 固定搭配a piece of，good以辅音音素开头，故填a；
42. 此处指“人类”，需用human的复数形式，故填humans；
43. 修饰动词sell，需用wide的副词形式，故填widely；
44. 指代前文的teammates，用人称代词主格，故填they；
45. so far是现在完成时的标志，主语是they，故填have planned。
【答案】
36. be sold 37. greater 38. if/whether 39. stay 40. on 41. a 42. humans 43. widely 44. they 45. have planned
