Let’s laugh more every day! 详细解析（答案+考点+语法规则+依据） 1. 答案：a 解析：考点为不定冠词的用法。此处修饰可数名词单数thing（事情），表示“一件好事”，great是以辅音音素开头的单词，故用不定冠词a。依据上下文，前文肯定“爱笑”的行为，此处需体现“一件极好的事”，符合语境逻辑。语法规则：不定冠词a/an用于修饰可数名词单数，表示泛指“一个、一件”，辅音音素开头用a，元音音素开头用an。 2. 答案：learn 解析：考点为一般现在时的动词形式。主语babies（宝宝们）是复数，且句子陈述的是客观事实（宝宝三个月左右学会笑），故谓语动词用原形learn。依据前一句“People start laughing from a young age.（人类从小就开始笑）”，此处为客观事实描述，用一般现在时。语法规则：一般现在时中，主语是复数时，谓语动词用原形。 3. 答案：natural 解析：考点为词性转换（名词变形容词）。此处修饰名词part（部分），需用形容词作定语，nature（名词，自然）的形容词形式是natural（自然的）。依据前文“Even babies that cannot see or hear can laugh.（即使失明失聪的宝宝也能笑）”，说明笑是“自然的”，贴合语境。语法规则：名词需通过词形变化（加后缀-al等）变成形容词，修饰名词作定语。 4. 答案：in 解析：考点为固定短语搭配。take in是固定短语，意为“吸入、吸收”，此处表示“笑的时候，身体会吸入更多氧气”，符合句意。依据后文“Every part of our body needs oxygen to work well.（身体的每个部分都需要氧气才能正常运转）”，此处需体现“吸入氧气”，固定搭配take in贴合语境。语法规则：take in为固定短语，后接名词，表“吸入、吸收”，类似搭配还有take out（拿出）、take off（起飞）。 5. 答案：work 解析：考点为使役动词make的用法。make sb./sth. do sth. 是固定结构，意为“使某人/某物做某事”，故此处用动词原形work。依据后文“Our heart, stomach, and even our shoulders work hard when we laugh!（笑的时候，我们的心脏、肠胃甚至肩膀都会努力活动）”，此处体现“笑让身体活动起来”，符合make的用法。语法规则：使役动词make、let、have后接宾语时，宾语补足语用动词原形，即make sb./sth. do sth.。 6. 答案：painful 解析：考点为词性转换（名词变形容词）。此处作系动词feel（感到）的表语，需用形容词，pain（名词，疼痛）的形容词形式是painful（疼痛的），feel less painful意为“感到不那么疼”。依据前文“create special chemicals to help us feel less...（分泌特殊化学物质帮助我们感到不那么……）”，结合常识，这些化学物质能减轻疼痛，故用painful。语法规则：系动词（feel、look、sound、be等）后接形容词作表语，说明主语的状态。 7. 答案：to release 解析：考点为动词cause的固定用法。cause sb./sth. to do sth. 是固定结构，意为“促使某人/某物做某事”，故此处用动词不定式to release（释放）。依据句意“笑还会促使大脑释放能让我们感到平静和快乐的化学物质”，贴合cause的用法。语法规则：cause后接宾语时，需用动词不定式作宾语补足语，即cause sb./sth. to do sth.，不可直接接动词原形。 8. 答案：smiling 解析：考点为动名词作主语。此处是宾语从句的主语，需用动名词形式，smile（动词，微笑）的动名词是smiling，意为“常常微笑”。依据前文“Laughing also causes our brain to release chemicals...（大笑会促使大脑释放化学物质）”，此处延续“笑/微笑的益处”，用smiling作主语符合语法。语法规则：动词不能直接作主语，需变成动名词（doing形式）或动词不定式（to do形式），此处表示习惯性动作，用动名词更合适。 9. 答案：others 解析：考点为不定代词的用法。other（形容词，其他的）后需接名词，此处空后无名词，需用others（代词，其他人），表示“当我们在其他人身边时”。依据前一句“But it is not always easy to laugh on our own.（独自一人时，我们往往很难笑出来）”，此处对比“独处”和“在其他人身边”，others贴合语境。语法规则：other作形容词，修饰名词复数；others作代词，相当于“other+名词复数”，泛指“其他人/物”；the others特指“其余全部的人/物”。 10. 答案：so that 解析：考点为目的状语从句的引导词。此处后文“others will know that they are being friendly（其他人会知道他们是友好的）”是前文“people laugh（人们笑）”的目的，故用so that（为了、以便）引导目的状语从句。依据前文“Monkeys clean one another‘s fur to show friendship.（猴子通过互相梳理毛发表达友谊）”，此处类比人类“通过笑表达友好”，用so that体现目的，贴合逻辑。语法规则：so that引导目的状语从句，意为“为了、以便”，从句中常含can、will等情态动词/助动词。 11. 答案：so 解析：考点为代词的用法。此处指代前文“doing so”中的so，即“试着想一些有趣的事、努力笑一笑”这件事，避免重复，用so符合语境。依据前文“Although you might not want to laugh when you are sad（即使难过时你可能不想笑）”，此处表示“做这件事（笑）能让你心情变好”，so指代前文提到的动作，贴合逻辑。语法规则：so可作代词，指代前文提到的动作、情况或话语，避免重复表述。 12. 答案：but 解析：考点为并列连词的用法。前文“Laughter is free（笑是免费的）”和后文“it brings us countless benefits（它给我们带来无数益处）”之间是转折关系，故用but（但是）连接。依据句意，笑虽然免费，却有很大益处，转折关系贴合语境。语法规则：but作并列连词，连接两个语义相反或相对的句子，表转折关系；and表并列，or表选择，so表结果。 参考答案 1. a 2. learn 3. natural 4. in 5. work 6. painful 7. to release 8. smiling 9. others 10. so that 11. so 12. but Ⅲ、一、阅读填空（10空） Laughter Is the Best Medicine Do you often laugh with friends?

If you do, that is great, because just as the saying goes: Laughter is the best medicine! People start laughing from a young age. At around three months old, babies learn to laugh. Even babies that cannot see or hear can laugh. Laughter is a natural part of life! But why is it so important? First of all, laughter is good for our body. When we laugh, our body takes in more oxygen. Every part of our body needs oxygen to work well. Laughter also makes our body work out. Our heart, stomach, and even our shoulders work hard when we laugh! But after we laugh, our muscles feel more relaxed. A good laugh can help you feel relaxed for up to 45 minutes. Over time, laughter helps our body to get stronger, fight off more diseases, and even create special chemicals to help us feel less pain! Laughter also has many benefits for our mood. When we laugh, it makes us feel less stressed or anxious, and things will not seem so bad. Laughing also causes our brain to release chemicals that make us feel calm and happy. Scientists even think that smiling often is enough to increase these chemicals in our brain. But it is not always easy to laugh on our own. We are 30 times more likely to laugh when we are around others. According to some scientists, laughter can show others that we want to be close to them. Monkeys clean one another‘s fur to show friendship. But people laugh so that others will know that they are being friendly. Some people even join laughing groups. Although they force themselves to laugh at first, after hearing other people laugh, their laughter becomes real! Before long, the whole group of people is laughing hard. The next time you feel unhappy, try thinking about something funny. Although you might not want to laugh when you are sad, doing so can make you feel better! 笑是最好的良药 你常和朋友们一同开怀大笑吗？你会因笑话忍俊不禁吗？如果答案是肯定的，那再好不过了，因为正如俗语所言：笑是最好的良药！ 人类从很小的时候就会笑了。宝宝在大约三个月大时，就学会了笑，就连失明失聪的宝宝也能绽放笑容。笑，是生活中与生俱来的美好存在！可它为何如此重要呢？ 首先，笑对我们的身体大有益处。大笑时，我们的身体会吸入更多氧气，而身体的各个器官运转都离不开氧气。笑还能让身体动起来，大笑的瞬间，我们的心脏、肠胃，甚至肩膀的肌肉都会跟着用力活动！但笑过之后，肌肉会变得更加放松。一场开怀的大笑，能让你保持放松的状态长达 45 分钟。久而久之，笑能让我们的身体变得更加强健，抵御更多疾病，还能促使身体分泌特殊的化学物质，帮我们减轻疼痛感。 笑对我们的情绪也有着诸多益处。大笑能驱散我们的焦虑与压力，让原本糟糕的事情，看起来也没那么难以接受。大笑还会促使大脑分泌化学物质，让我们感到平静又愉悦。科学家甚至发现，常常微笑，就足以让大脑里的这类愉悦化学物质增多。 但独自一人时，我们往往很难笑出来。和他人相处时，我们笑的概率会比独处时高出 30 倍。据一些科学家研究发现，笑是一种信号，向他人表达我们想要亲近彼此的心意。猴子会通过互相梳理毛发来表达友好，而人类则会用笑，让身边的人感受到自己的善意。 有些人还会加入笑疗小组。起初，他们或许是刻意逼着自己笑，但听到身边人的笑声后，笑容便会变得发自内心。没过多久，整个小组的人就都会开怀大笑起来。 下次感到不开心时，不妨试着想一些有趣的事。即便难过时根本笑不出来，也请努力笑一笑，这会让你的心情慢慢变好的！ 学科网（北京）股份有限公司 $
