Oscar told me that it's really hard to get good food.Most of what is given out is past the sell-by dates.He is always grateful for the food, but he has an autoimmune (自身免疫的) disease so these kinds of foods are really making it worse.Now that spring is here, hopefully, he can get fresher produce. I told him about the book I'm reading by Will Bulsiewicz, MD called Fiber Fueled.I'm learning so much.Today is day 70 since I started learning to make meals just from plants.The more I learn about plant-fueled eating, the better I feel about this decision.And this book is specifically about taking advantage of the body's capacity to cure itself.So my friend ordered the audio from the library and it will come in soon.He wants to learn about this too since he has serious autoimmune issues.That's why he lost his job and then his apartment. Oscar is a young man I can help.I want him to heal and find a job and a home again.I know he can do it.And I won't stop helping him until that happens.Once my social security checks come in, I plan to make sure he gets Kroger cards every time I get paid so that he has plenty of healthy produce. Oscar's page on social media is @MyHomelessMeals.More than anything, he shows gratitude for every single person who helps him on a daily basis.He always shares what we send if he can, too.He recently joined Service Space because he said their Mission Statement is aligned with his values.He's quite an exceptional young man. 语篇解读：本文是一篇记叙文。文章讲述了作者帮助失去工作和住所而且患有免疫系统疾病的年轻人Oscar的故事。 1．Why did the foods Oscar received make his disease worse? A．They are rich in fat. B．They are a little raw. C．They are hard to digest. D．They are not so fresh. √ 解析：细节理解题。根据第二段二、三句可知，Oscar领取到的救济食物多数过期了，不新鲜的食物让患有免疫系统疾病的他雪上加霜。 2．What's the main idea of the third paragraph? A．The author introduced a proper book to Oscar. B．Oscar's disease made him lose everything. C．Oscar wanted to cure his disease quickly. D．The author gave Oscar a book as a gift. √ 解析：段落大意题。根据第三段第一句及倒数第二、三句可知，作者将自己正在阅读的一本书Fiber Fueled推荐给Oscar，作者认为这本书对Oscar的身体健康很有帮助。 3．How will the author help Oscar cure his illness? A．By helping Oscar get a well-paid job. B．By making sure Oscar can get healthy food. C．By recommending some restaurants to Oscar. D．By introducing Oscar to some famous doctors. √ 解析：细节理解题。根据第四段最后一句可知，作者在帮助Oscar获得健康新鲜的食物，这些食物有助于改善身患免疫系统疾病的Oscar的健康状况。 4．What does the underlined phrase “is aligned with” in the last paragraph probably mean? A．Transforms.　　　　　 B．Matches. C．Allows. D．Controls. 解析：词义猜测题。根据画线句的前半部分“He recently joined Service Space”可知，Oscar加入了一个公益组织，可推测加入的原因是这个组织传递的价值观和他的一致，即互相匹配。故画线短语与“matches”为同义词。 √ B (2024·湘潭模拟)When was the last time you showed off your being sensitive? Most likely, the answer is never.There are plenty of traits (特性) we take pride in but being “sensitive” is usually seen as a weakness.It's used to mean you're fragile (脆弱的), thin-skinned or just overreacting, but it's wrong-headed.Sensitivity is largely genetic, and not something you can turn off.It is a trait linked to giftedness and something we ought to embrace. As a personality trait, being sensitive means you take in more information from your environment, and you do more with it.Sensitive people are better at a brain level to process information more deeply than others do.The most well-known and celebrated sensitive gift is creativity.Sensitive people have this capacity for innovation (创新) because they tend to be deep thinkers who spend more time and energy turning problems over in their heads and end up seeing more possibilities and solutions. Many — perhaps most — artists, musicians, actors and even scientists are themselves sensitive people, including Charles Darwin — the model of a sensitive person. Sensitive people do pay a price for these gifts, however, by becoming overstimulated.Overstimulation is what happens when there is simply too much information for the brain to keep going deep.It happens in situations that are too loud, too chaotic, or too emotionally intense (紧张的)．This is the only time when sensitive people really might seem less “tough” than others, but sensitive people can learn to largely prevent it.For example, a little bit of quiet alone time goes a very long way. If any of this sounds like you, you might be more sensitive than you realize.If so, you have probably felt the pressure to hide it.But that's a trap.You cannot make yourself less sensitive than you are and trying to do so only cuts you off from your gifts.Instead, the single most important step you can take for yourself is what society has told you not to do your whole life: Stop hiding from your sensitivity.Embrace it, and show it to the world. 语篇解读：本文是一篇说明文。文章主要讲述了敏感体质的优、缺点。 5．What is the general attitude of people toward being “sensitive”？ A．Positive. B．Negative. C．Tolerant. D．Indifferent. √ 解析：观点态度题。根据第一段中的“There are plenty of traits we take pride in but being ‘sensitive’ is usually seen as a weakness.”可知，人们对“敏感”的普遍态度是消极的。 6．What does the second paragraph describe about sensitive people? A．Strengths. B．Characters. C．Disadvantages. D．Innovation. 解析：细节理解题。本段主要描述了敏感的人更能创新，更富有创造力，也就是敏感的人的长处。 √ 7．What will be the best advice to sensitive people if they become overstimulated? A．To play sports with friends. B．To talk to a friend about troubles. C．To rest in a peaceful place alone. D．To play computer games at home. √ 解析：细节理解题。根据倒数第二段的“For example, a little bit of quiet alone time goes a very long way.”可知，如果敏感的人受到过度刺激，对他们最好的建议是找到一个安静的地方独自休息。 8．What is the effect of hiding from your sensitivity? A．Being less talented. B．Feeling comfortable. C．Getting more sensitive. D．Becoming confident. √ 解析：推理判断题。根据最后一段中的“But that's a trap ... trying to do so only cuts you off from your gifts.”可知，隐藏自己的敏感会削弱自己的天赋。 Ⅱ.阅读七选五 (2024·济南模拟)It's easy to stick to eating the same foods every day, especially if you love them. 9 Eating the same foods can lead to nutritional shortage.Our bodies need a wide range of nutrients, and eating a wide variety of foods can help us meet our bodies' needs. 10 Almost everyone would agree that “eating the rainbow” is a good rule of thumb.Don't forget frozen vegetables are just as healthy as the fresh ones and that they don't spoil quickly. Your immune system (免疫系统) will get hurt if you keep eating the same foods.According to a study published in the British Journal of Nutrition, the enhanced nutrition from varied diets seems to boost immunity. 11 People whose diets have little variation are more likely to get sick due to a weakened immune system. Sticking to eating the same foods leads to food boredom. 12 It should be something you look forward to.Changing what you eat exposes you to great new foods and new recipes, and helps bring back the fun in eating. 13 We see a lot of people focus on a single nutrient or food because it attracts media fame.And while all foods are to be celebrated for their unique nutritional quality, assigning yourself to a limited list of foods because they are the most well-known or well described will box you in and close you off from various other vital nutrients. A．Food should be fun! B．This helps people resist infections. C．But it may not be the best thing for your health. D．You should eat a plant-based diet and eat less meat. E．Eating the same foods restricts your nutritional sources. F．Though tasty, they can't provide the nutrition you need. G．Eat the colors of the rainbow when it comes to fruit and vegetables. 语篇解读：本文是一篇说明文。文章主要介绍了坚持每天吃同样的食物对身体健康的坏处。 9．解析：选C　根据空前一句“坚持每天吃同样的食物很容易，尤其是如果你喜欢它们”和第二段第一句“吃同样的食物会导致营养不足”可知，空处与前一句构成转折关系，故C项“但这很可能对你的健康不是最好的事情”承上启下，符合语境。 10．解析：选G　根据空后一句中的“eating the rainbow”可知，空处应有与“eating the rainbow”相关的内容，故G项“说到水果和蔬菜，吃像彩虹那样多姿多彩的颜色(的水果和蔬菜)”衔接下文，符合语境。 11．解析：选B　空前一句提到，吃多样的食物似乎会增强免疫力，而空后一句提到，饮食不怎么变化的人更容易生病，故B项“这有助于人们抵抗感染”承上启下，符合语境。 12．解析：选A　空前一句提到，坚持吃同样的食物会让人觉得厌烦，而空后一句提到，“这”应是你盼望已久的事情；因此，空处提到的应该与“boredom”的意思相反，A项中的“fun”与之呼应，空后的“It”指代A项中的“Food”。故A项“食物应该有乐趣”承上启下，符合语境。 13．解析：选E　根据本段中的“will box you in and close you off from various other vital nutrients”可知，单一食物会把你和其他关键的营养源阻隔开，故E项“吃同样的食物会限制你的营养源”适合作本段的主旨句。 Ⅲ.完形填空 (2024·湖北名校联考)My baby son was in the hospital, connected to a NG tube (鼻饲管)． I just couldn't stand the 14 sight of food being slowly pushed through his nose into his stomach.The lovely dreams I had of nursing my baby, and rocking him while he fed, were 15 .
