閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)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 (飽和的) 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 (堿) 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?

【解析】
【導(dǎo)語(yǔ)】這是一篇說(shuō)明文。文章主要是對(duì)一些常見(jiàn)的飲食相關(guān)的說(shuō)法進(jìn)行了分析和解釋，以幫助人們更好地理解和選擇飲食。
【1題詳解】
細(xì)節(jié)理解題。根據(jù)第二段“If it comes from a land-based animal, and is likely to be solid at room temperature, then it is saturated (飽和的) 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.(如果它來(lái)自陸生動(dòng)物，在室溫下很可能是固體，那么它就是飽和脂肪；如果它來(lái)自魚類或植物，在室溫下很可能是液體，那么它就是不飽和脂肪。所有證據(jù)都表明，攝入更多的不飽和脂肪比攝入更多的飽和脂肪能降低早逝的風(fēng)險(xiǎn))”可知，魚類和植物中含有更健康的脂肪。故選A。
【2題詳解】
推理判斷題。根據(jù)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?(簡(jiǎn)單的食物不一定對(duì)你更健康。例如，如果我在菜譜中使用了中國(guó)的五香粉，它就會(huì)被算作五種配料之一。然而，如果我把五種香料粉的典型成分分別加入到一道菜中呢？這是否意味著我的食譜突然變壞了，因?yàn)樗谐^(guò)五種原料？)”可推知，含有更多佐料的食物可能也一樣健康，故選C。
【3題詳解】
推理判斷題。根據(jù)文章主要講了一些關(guān)于飲食的常見(jiàn)誤解，如脂肪的好壞、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，目的是提醒人們注意這些飲食方面的誤解，故選D。
