阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑。
A
With all the dietary information online, it can be hard to know what tips to follow. Watch out for these words and expressions.
Fat Is Good
It doesn’t matter if you are part of the fat is GOOD for you or BAD for you group, the important question to ask is the source of the fat. If it comes from a land-based animal, and is likely to be solid at room temperature, then it is saturated (饱和的) fat whereas if it comes from fish or plants, and it is likely to be liquid at room temperature, then it is unsaturated fat. All the evidence indicates that eating more unsaturated fat than saturated fat lowers your risk of dying early.
Natural Sugar Is Better
The vast majority of sugar we consume is sucrose (蔗糖). It is the white powdered stuff we cook with and is made up of glucose and fructose. How about sugar from honey? It is often marketed as natural and better for you. Actually, it just has its own distinct flavour, but is as sweet because of glucose and fructose.
High-pH Water
Some people think we need to eat alkali (碱) food to maintain our blood at a pH of 7.4. But everything we eat or drink passes through the stomach, which, at a pH of 1.5, is the most acidic part of the body. It is then neutralised to a pH of 7. So, nothing we eat will change the pH of our blood.
Don’t Eat Anything That You Can’t Pronounce
Whether foods are natural or highly processed, they are all full of chemicals. Are you supposed to fear “phenylthiocarbamide”, because you can’t pronounce it? This is simply the chemical responsible for the bitter taste found in brassicas, the plants in the cabbage and mustard family.
Don’t Eat Food With More Than Five Ingredients(佐料)
Simple foods are not necessarily healthier for you. If I
for instance, use Chinese five spice powder in a recipe, that would count as one of the five ingredients. However, what if I added the typical components of five spice powder separately into a dish? Does that mean my recipe suddenly becomes bad because it has more than five ingredients?
1. According to the passage, healthier fat ______.
A. can be found in fish and plants B. comes from land-based animals
C. remains solid at room temperature D. can lower the death rate of elders
2. The passage suggests that ______.
A. diets can help adjust the pH of our blood B. honey sugar can do more good than sucrose
C. foods with more ingredients may be as healthy D. chemicals we can recognize are safer to take in
3. What is the main purpose of the passage?
A. To compare tips on food choices. B. To introduce different health concepts.
C. To recommend fitness recipes to readers. D. To warn us of some dietary misunderstandings.
【答案】1. A 2. C 3. D
【解析】
【导语】这是一篇说明文。文章主要是对一些常见的饮食相关的说法进行了分析和解释，以帮助人们更好地理解和选择饮食。
【1题详解】
细节理解题。根据第二段“If it comes from a land-based animal, and is likely to be solid at room temperature, then it is saturated (饱和的) fat whereas if it comes from fish or plants, and it is likely to be liquid at room temperature, then it is unsaturated fat. All the evidence indicates that eating more unsaturated fat than saturated fat lowers your risk of dying early.(如果它来自陆生动物，在室温下很可能是固体，那么它就是饱和脂肪；如果它来自鱼类或植物，在室温下很可能是液体，那么它就是不饱和脂肪。所有证据都表明，摄入更多的不饱和脂肪比摄入更多的饱和脂肪能降低早逝的风险)”可知，鱼类和植物中含有更健康的脂肪。故选A。
【2题详解】
推理判断题。根据最后一段“Simple foods are not necessarily healthier for you. If I, for instance, use Chinese five spice powder in a recipe, that would count as one of the five ingredients. However, what if I added the typical components of five spice powder separately into a dish? Does that mean my recipe suddenly becomes bad because it has more than five ingredients?(简单的食物不一定对你更健康。例如，如果我在菜谱中使用了中国的五香粉，它就会被算作五种配料之一。然而，如果我把五种香料粉的典型成分分别加入到一道菜中呢？这是否意味着我的食谱突然变坏了，因为它含有超过五种原料？)”可推知，含有更多佐料的食物可能也一样健康，故选C。
【3题详解】
推理判断题。根据文章主要讲了一些关于饮食的常见误解，如脂肪的好坏、天然糖是否更好、高pH值水是否更好、以及佐料多的食物是否不好，目的是提醒人们注意这些饮食方面的误解，故选D。
