阅读下面的短文,在空白处填入一个适当的词,或填入括号中所给单词的正确形式。

This new purple tomato could soon 36

(sell) in the US. A team of scientists, including Dr Cathie Martin, developed the special kind of tomato by making changes to its DNA. Though the colour is unusual, they have much 37 greater
(great) antioxidants(抗氧化剂) than normal tomatoes.Dr Martin wanted to see 38
if/whether
she could develop tomatoes with lots of antioxidants by changing the DNA of a tomato plant. She found out that purple tomatoes could 39 stay
(stay) fresh almost twice as long as normal tomatoes. Then she tested the tomatoes 40 on
mice that would probably get cancer. The ones who ate the purple tomatoes lived about 30% longer than those who ate normal tomatoes. That's 41 a
good piece of news, the results of animal studies don't always work in 42 humans
(human). So the teammates had to reach agreements with the US government to grow and sell the purple tomatoes 43 widely
(wide) in the US. Finally, 44 they
succeeded on September 7th, 2022.So far, they 45
have planned
(plan) to introduce the tomatoes across the US. They also hope to sell the seeds(种子) to people who want to grow their own.Do you want to try the purple tomatoes?

解析
【分析】
做语法填空时,需先通读全文理解短文主旨,再结合每个空格前后的语境、语法结构、固定搭配、时态语态等知识点逐一分析。本题围绕紫色番茄的研发展开,考点涵盖被动语态、形容词比较级、宾语从句引导词、情态动词用法、固定搭配、冠词、名词复数、副词用法、代词、现在完成时等,需根据具体语境和语法规则填写正确形式。
【解析】
36. 考查被动语态。情态动词could后接动词原形,主语this new purple tomato与动词sell是被动关系(番茄被售卖),故填be sold。
37. 考查形容词比较级。由句中than(比)可知,此处需用形容词great的比较级形式,故填greater。
38. 考查宾语从句引导词。根据句意“Dr Martin想看看是否能培育出含大量抗氧化剂的番茄”,空格处表示“是否”,引导宾语从句,故填if/whether。
39. 考查情态动词用法。情态动词could后需接动词原形,故填stay。
40. 考查固定搭配。test sth on sb是固定搭配,意为“在某人/动物身上测试某物”,此处指在老鼠身上测试番茄,故填on。
41. 考查冠词。a good piece of是固定表达,意为“一条好消息”,good以辅音音素开头,故填不定冠词a。
42. 考查名词复数。此处指代“人类”,human是可数名词,表泛指时需用复数形式,故填humans。
43. 考查副词。空格处修饰动词短语grow and sell,需用副词形式,故填widely。
44. 考查代词。此处指代前文提到的“teammates(团队成员)”,是复数概念,在句中作主语,故填主格代词they。
45. 考查现在完成时。由时间状语so far(到目前为止)可知,句子需用现在完成时,结构为“have/has + 过去分词”,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
【知识点】
被动语态、形容词比较级、现在完成时
【点评】
本题为科技主题的语法填空,考查初中阶段核心语法知识点,注重语境与语法规则的结合,难度适中,适合学生巩固基础语法。
