二、阅读理解
Of course, we know that sugar isn't good for us. But could it really be that bad if it tastes so delicious? Sadly, yes.
"Everyone loves sugar," says Dr Robert Lustig, a sugar expert. "But sugar has a dark side." Take breakfast for example. Sugary cereal gives you energy, but only for a short time. Then you start to feel sleepy. Foods like oatmeal and fruit give your body energy for hours. And, eating a lot of sugar can cause health problems, including serious illnesses. These days, more and more children are getting illnesses caused by eating too much sugar.
The good news is that changing your diet can help—and fast. Lustig recently does a study that helps overweight children eat less sugar. All of the children who cut out sugar have fewer health problems in just 10 days.
Knowing the risks of eating too much sugar can help you make healthy food choices. Does this mean you have to give up sugar completely? No. It just means you should make sure you are eating plenty of healthy foods, like fresh fruit and vegetables. Most of us can eat candies sometimes, but just make sure it's not your dinner.

解析
【分析】
这是一篇介绍糖相关知识的健康类说明文阅读理解，解题时可以按照以下思路推进：1. 先通读全文，梳理出文章核心是介绍过量摄入糖的危害以及合理摄入糖的正确方式，把握整体行文逻辑；2. 针对细节类题目，带着题干的关键词返回原文精准定位，找到对应语句后和选项逐一比对，排除无中生有的错误选项；3. 词义猜测题结合划线词前后的语境内容，关联上下文提到的食物、进食相关的描述推导词义；4. 主旨标题类题目要选择能覆盖全文核心内容的选项，排除只覆盖局部内容的片面干扰项，即可顺利得出所有题目的答案。
【解析】
1. 细节理解题：定位到原文第二段最后一句"These days, more and more children are getting illnesses caused by eating too much sugar."，明确说明越来越多孩子生病的原因是摄入过多的糖，对应选项A，B、C、D的内容文中均未提及，因此选A。
2. 细节判断题：根据第二段内容可知，含糖麦片只能给人体提供短时间的能量，之后人会犯困，而燕麦和水果可以为人体提供数小时的能量，由此能判断燕麦是比含糖麦片更好的能量选择，对应选项C。选项A文中没有提到糖果助眠的相关内容，选项B第二段没有表述早餐是一天中最重要的一餐，选项D文中完全没有提及儿童每日可摄入的糖比成人多，均不符合原文，因此选C。
3. 词义猜测题：划线词"diet"所在的上下文都在围绕健康食物、减少糖分摄入的饮食调整展开，和进食、食物选择相关，因此这个单词的中文含义是"饮食"，对应选项A。
4. 细节理解题：定位到原文最后一段，文中提到了解过量吃糖的风险可以帮助我们做出健康的食物选择，不需要完全放弃糖，要保证摄入大量的健康食物，偶尔可以吃糖果但不能把它当正餐，对应选项D。选项A文中没有提到要自己制作健康食物，选项B"完全放弃糖"和原文表述相悖，选项C"把糖果当晚餐"是文中明确反对的错误做法，因此选D。
5. 主旨大意题：全文围绕糖展开，既介绍了过量摄入糖的危害，也说明了不需要完全戒糖、合理摄入的正确方式，核心是介绍关于糖的真实情况。选项A只提到孩子喜欢糖果过于片面，选项C仅聚焦早餐不符合全文核心，选项D超重的危害不是文章的论述重点，因此最佳标题是B。
【答案】
1.A 2.C 3.A 4.D 5.B
【知识点】
细节定位阅读，词义猜测，主旨判断
【点评】
本篇是贴近生活的健康主题说明文，整体难度偏低，绝大多数题目都可以通过回原文定位直接找到答案，适合用来锻炼基础阅读信息提取能力，做这类题时注意不要自己主观臆断，所有判断都要从原文给出的内容出发，就能有效避免丢分。
