解析
【分析】
本题为英语阅读理解题，围绕“食物彩虹（不同颜色蔬果的健康功效）”展开，共5道选择题，涵盖细节理解、词义猜测、主旨大意、文章结构四类考点。解题时需先通读全文把握主旨，再针对每道题的设问，定位原文对应内容，逐一分析选项排除干扰项，得出正确答案。
【解析】
1. 第1题：设空处位于第二段（红色蔬果介绍段），前文讲红苹果的功效，后文提到“代替糖果”，需补充红色蔬果的健康相关内容。选项A“红浆果能帮助预防生病”属于红色蔬果的功效，符合段落主题；B选项“红苹果被称为天然牙刷”原文未提及；C选项“葡萄”属于紫色蔬果，与本段红色主题不符；D选项“每天吃苹果”与后文“代替糖果”衔接不紧密，故选A。
2. 第2题：题干问“快速获得更多能量的食物”，定位原文第四段第一句“A yellow banana can give you lots of energy.”，可知香蕉能提供大量能量，故选B。
3. 第3题：“rich”所在句描述青豆的营养，结合语境“富含维生素B、C、K”，此处“rich”意为“含有大量有益物质”，对应选项D；A“尝起来甜”、B“颜色深”、C“有钱”均不符合语境，故选D。
4. 第4题：全文围绕不同颜色蔬果的健康作用展开，核心是说明“为什么要吃食物彩虹”，A选项“如何制作彩虹”偏离主题；B选项“每天吃多少种颜色”是细节而非主旨；D选项“为什么要健康饮食”范围过大，未紧扣“食物彩虹”，故选C。
5. 第5题：文章结构为：第一段总起（引入“食物彩虹”概念）→2-7段分述不同颜色蔬果的功效→最后一段总结（强调吃食物彩虹有益健康），即总-分-总结构，对应选项A，故选A。
