B 【解析】细节理解题。根据第一段“Often we are too busy or feel lazy.”可知，人们不常运动是因为太忙或太懒，A（运动不重要）与原文首句“exercise is important”相反，C（运动让他们累）、D（没时间睡觉）均无依据，故选B。 2. C 【解析】细节理解题。根据第二段“Exercise develops our muscles and makes us stronger... This keeps our weight down.”可知，运动能锻炼肌肉、保持健康（控制体重），A（让我们超重）、B（导致背痛）、D（增加身体压力）均是“超重”的危害，并非运动的作用，故选C。 3. B 【解析】细节理解题。根据第二段“Our brain gets more oxygen because of this, and that helps our memory improve.”可知，运动能帮助记忆力提升，A（让心跳变慢）与原文“heart beats faster”相反，C（减少大脑氧气）与原文“more oxygen”相反，D（让我们忘记作业）与原文“do some exercise, then try again”相反，故选B。 4. A 【解析】细节理解题。根据第三段“Exercise also helps us to feel happier... make us feel better and more confident about ourselves.”可知，运动能让我们更开心、更自信，B（懒惰疲惫）、C（有压力悲伤）、D（焦虑紧张）均是缺乏运动可能的状态，故选A。 5. C 【解析】句意猜测题。结合全文强调“运动对健康的重要性”，以及后句“The more you exercise, the healthier you become.”可知，“Health is wealth”（健康是财富）的含义是“健康是最重要的事”，A（财富比健康重要）、B（健康和财富同等重要）、D（财富能买到健康）均不符合语境，故选C。 二、阅读表达（每题3分，满分15分） 1. Every day. 【解析】细节理解题。根据第一段“But we should try our best to exercise every day.”可知，我们应该每天运动，简洁回答频率，控制在10词内。 2. Heart disease (and back pain). 【解析】细节理解题。根据第二段“It can cause pain in our back and knees, and even cause more serious problems such as heart disease later in life.”可知，超重会导致背痛、心脏病等，提炼核心问题。 3. Oxygen. 【解析】细节理解题。根据第二段“Our brain gets more oxygen because of this”可知，运动时大脑能获得更多氧气，直接回答名词。 4. Do some exercise then try again. 【解析】细节理解题。根据第二段“So, when you have trouble with your homework, do some exercise, then try again!”可知，作业遇到困难时，先运动再尝试，提炼动作短语。 5. It makes special chemicals. 【解析】细节理解题。根据第三段“When we exercise, our brain makes special chemicals. These chemicals can relax our body and calm our mind.”可知，运动让人开心是因为大脑会产生特殊化学物质，简洁概括。 三、短文还原（七选五）（每题2分，满分10分） 1. A 【解析】前句讲“我们都知道运动重要，但不总是想做”，后句讲“但我们应该尽力每天运动”，A项“我们经常太忙或太懒”承接前句，解释“不想运动”的原因，形成“提出问题→解释原因→给出建议”的逻辑，衔接自然。 2. B 【解析】前句讲“运动时我们的身体会变化”，后句讲“运动消耗能量，帮助控制体重”，B项“运动锻炼肌肉，让我们更强壮”是“身体变化”的具体表现，与后句的“控制体重”并列，共同说明运动对身体的好处，符合语境。 3. E 【解析】前句讲“超重会给身体带来压力”，后句讲“甚至导致更严重的问题，比如心脏病”，E项“它会导致背痛和膝盖痛”是超重的危害之一，介于“压力”和“心脏病”之间，形成“轻微危害→严重危害”的递进，衔接紧密。 4. C 【解析】前句讲“运动时心跳加快、呼吸更急促”，后句讲“这帮助记忆力提升”，C项“因此大脑能获得更多氧气”填补中间逻辑，“心跳快、呼吸急”是“获得更多氧气”的原因，“更多氧气”是“记忆力提升”的原因，逻辑连贯。 5. D 【解析】前句讲“运动时大脑会产生特殊化学物质”，后句讲“身体健康也能让我们更自信”，D项“这些化学物质能放松身体、平静心情”解释“特殊化学物质”的作用，承接前句，说明运动让人开心的原因，符合语境。 四、用所给单词的正确形式填空（每题1分，满分10分） 1. don’t always want 【解析】时态为一般现在时，主语“we”是复数，否定形式用“don’t+动词原形”，故填don’t always want。 2. bodies 【解析】body是可数名词，此处表泛指“我们的身体”（每个人的身体），需用复数形式bodies。 3. stronger 【解析】“make sb.+形容词”意为“让某人变得……”，结合语境“运动让我们更强壮”，用strong的比较级stronger（暗含“比不运动时更强壮”）。 4. stress 【解析】stress是不可数名词，意为“压力”，“put stress on...”是固定搭配，意为“给……带来压力”，无需变复数。 5. disease 【解析】diseased是形容词（患病的），此处需用名词作宾语；disease（疾病）是名词，“heart disease”意为“心脏病”，为固定搭配。 6. beats 【解析】此处是when引导的时间状语从句，主句时态为一般现在时（breathe），从句也用一般现在时；主语“our heart”是单数，谓语动词beat用第三人称单数形式beats。 7. (to) improve 【解析】“help sb./sth. (to) do sth.”是固定句型，意为“帮助某人/某物做某事”，to可省略，此处填improve或to improve均可。 8. chemicals 【解析】chemical是可数名词，前面有“special”（特殊的）修饰，且结合后文“These chemicals”可知，此处需用复数形式chemicals。 9. minds 【解析】mind是可数名词，主语“our”（我们的）对应复数，故用minds（思想、头脑），与“bodies”并列，保持形式一致。 10. healthier 【解析】“the+比较级，the+比较级”是固定结构，意为“越……，就越……”，healthy的比较级为healthier（以y结尾，变y为i加er）。 五、书面表达（满分15分） 【范文】 Dear Tom, I know you seldom exercise and often feel tired. I want to tell you exercise is really good for you. Exercise can develop your muscles and keep you fit. It also helps your brain get more oxygen, so your memory will improve.
