1. 说建议和需要做的事\n\n给朋友建议，或说明有些事需要做，可以用**应该**和**得**。两者的意思不完全一样：**应该**常说怎么做比较好、比较对；**得**常说因为时间、规定等原因，需要这样做。\n\n- 用**应该**给建议、说应该做的事。\n- 用**得**说明需要做的事。\n- 注意两者的读音、位置和否定说法。\n\n:::example\n你最近太累了，**应该**早点休息。\n\n明天八点有考试，我**得**早点起床。\n:::\n\n## 2. 放在动词前面\n\n基本顺序是：**人＋应该／得＋动词或动词短语**。换一个人说，形式不变。\n\n这里的**得**读 **děi**，不读 de 或 dé。\n\n| 形式 | 例句 |\n| --- | --- |\n| 我＋应该＋做什么 | 我**应该**给妈妈打个电话。 |\n| 你＋应该＋做什么 | 你**应该**多喝水。 |\n| 我＋得＋做什么 | 我**得**去上班。 |\n| 我们＋得＋做什么 | 我们**得**买票。 |\n\n时间可以放在“应该”或“得”前面。\n\n:::example\n我**今天得**交作业。\n\n你**晚上应该**早点睡觉。\n:::\n\n:::tip\n“早点”“先”等词常放在“应该”或“得”后面：**应该早点睡觉**、**得先买票**。\n:::\n\n## 3. 根据意思选词\n\n**应该**常用于建议，也可以说明怎样做才对，不只是给别人一个选择。**得**常用于口语，说明事情需要做，不能随便不做。\n\n| 情况 | 例句 | 想表达的意思 |\n| --- | --- | --- |\n| 给建议 | 你**应该**去看看医生。 | 看医生对你比较好。 |\n| 说怎样做才对 | 借了别人的东西，我们**应该**还。 | 还东西是对的。 |\n| 时间不够了 | 快迟到了，我们**得**走了。 | 现在需要走。 |\n| 有规定 | 这里先买票才能进去，我们**得**先买票。 | 不买票就不能进去。 |\n\n同一件事可以用不同的词，但说话的意思不同。\n\n:::example\n**朋友给建议：**你**应该**早点出门，路上车很多。\n\n**自己说明安排：**我明天六点的飞机，**得**早点出门。\n:::\n\n:::note\n“应该”不一定是很轻的建议。例如，“我们应该遵守学校的规定”是在说我们应该做的事。“得”强调需要这样做，不只是说这样做比较好。\n:::\n\n## 4. 否定时要换一种说法\n\n**不应该＋动词**表示这样做不好、不对。\n\n:::example\n这里有人在学习，你**不应该**大声说话。\n\n这是小李的东西，你**不应该**拿走。\n:::\n\n如果想说“没有必要做”，常用**不用＋动词**。这里只需要记住这个区别。\n\n| 意思 | 例句 |\n| --- | --- |\n| 需要去 | 我今天**得**去学校。 |\n| 没有必要去 | 今天学校放假，我**不用**去学校。 |\n| 这样做不好 | 你还在发烧，**不应该**去学校。 |\n\n:::warning\n不要把“不应该”理解成“没有必要”。\n\n**你不应该去。**＝你去不合适。\n\n**你不用去。**＝你没有必要去。\n\n表示“没有必要”时，不要直接在读 děi 的“得”前面加“不”。\n:::\n\n## 5. 开口前检查一下\n\n1. 想说“这样做比较好”或“这样做才对”？用**应该**。\n2. 想说“因为时间、规定等原因，需要这样做”？用**得**，读 **děi**。\n3. 想说“这样做不好”？用**不应该**。\n4. 想说“没有必要做”？用**不用**。\n\n记住：**应该早点走**是在说早点走比较好；**得早点走**是在说有原因，需要早点走。","zh","A2",76,[13],{"id":14,"name":5,"level":10,"language":9,"isCompleted":15,"completionPercentage":16,"totalExercises":17,"completedExercises":16},"01a0e1ad-b2ca-7b35-bf41-81707b73282f",false,0,2,"2026-09-27T07:04:13+00:00","2026-10-11T12:53:48+00:00",[21],{"id":22,"title":23,"vocabularyListWords":24,"isPublished":38},"01a0e1ae-194c-7306-a5d6-05ea752aeee8","必要与责任：应该、得",[25,41,58,72,92],{"id":26,"vocabularyWord":27,"displayOrder":39},"01a0e1ae-194c-73ba-a5d6-05ea762a847b",{"id":28,"word":29,"frequency":30,"level":10,"language":9,"audioFilePath":31,"partsOfSpeech":32,"audio":38,"audioUrl":40},"01a0e1ad-ece1-7bcf-a050-8c42006561e4","应该",10,"tts_39cd7ae01b3c9794_zh-CN.mp3",[33],{"id":34,"partOfSpeech":35,"definition":36,"exampleSentences":37,"isPrimary":38,"meaningOrder":39},"01a0e1ad-ed14-79d8-8b09-c08086be7baf","MODAL_VERB","表示按照道理、责任或推断，某种做法或情况较合适。","生病了应该多休息。",true,1,"\u002Fuploads\u002Faudio\u002Ftts_39cd7ae01b3c9794_zh-CN.mp3",{"id":42,"vocabularyWord":43,"displayOrder":17},"01a0e1ae-194c-73fe-a5d6-05ea7719ff5d",{"id":44,"word":45,"frequency":30,"level":10,"language":9,"audioFilePath":46,"partsOfSpeech":47,"audio":38,"audioUrl":57},"01a0e1ad-ece2-7ba9-bbb7-2138b07ed44a","得","tts_0806a62636da8ec8_zh-CN.mp3",[48,52],{"id":49,"partOfSpeech":35,"definition":50,"exampleSentences":51,"isPrimary":38,"meaningOrder":39},"01a0e1ad-ed14-7af4-8b09-c08087a422dc","读děi，表示客观或主观上必须做某事。","时间不早了，我得回家。",{"id":53,"partOfSpeech":54,"definition":55,"exampleSentences":56,"isPrimary":15,"meaningOrder":17},"01a0e1ad-ed14-7b44-8b09-c080881f98b5","PARTICLE","读de，放在动词或形容词后，引出程度或结果说明。","他汉语说得很流利。","\u002Fuploads\u002Faudio\u002Ftts_0806a62636da8ec8_zh-CN.mp3",{"id":59,"vocabularyWord":60,"displayOrder":71},"01a0e1ae-194c-742a-a5d6-05ea779bec1b",{"id":61,"word":62,"frequency":30,"level":63,"language":9,"audioFilePath":64,"partsOfSpeech":65,"audio":38,"audioUrl":70},"01a0e1ad-ed08-79f9-aae1-a4afd251562d","不用","B1","tts_e8f433655461d2b3_zh-CN.mp3",[66],{"id":67,"partOfSpeech":35,"definition":68,"exampleSentences":69,"isPrimary":38,"meaningOrder":39},"01a0e1ad-ed18-7726-af84-1e8ca1845415","口语中表示没有必要做某事。","离得很近，我们不用坐车。","\u002Fuploads\u002Faudio\u002Ftts_e8f433655461d2b3_zh-CN.mp3",3,{"id":73,"vocabularyWord":74,"displayOrder":91},"01a0e1ae-194c-744a-a5d6-05ea7898dece",{"id":75,"word":76,"frequency":77,"level":10,"language":9,"audioFilePath":78,"partsOfSpeech":79,"audio":38,"audioUrl":90},"01a0e1ad-f130-7eeb-aa66-c3e90156333e","早点",7,"tts_dffc5c9b5b082c7c_zh-CN.mp3",[80,85],{"id":81,"partOfSpeech":82,"definition":83,"exampleSentences":84,"isPrimary":38,"meaningOrder":39},"01a13173-39af-75c1-ad93-73b2cee03619","ADVERB","表示比平时、比原定时间或比现在更早一些地做某事，常用于建议、请求或提醒，多与动词连用，也可说“早一点”。","明天要考试，你今晚早点睡吧。\n我们早点出发，路上就不会堵车了。\n下次请早点告诉我，我好提前准备。",{"id":86,"partOfSpeech":87,"definition":88,"exampleSentences":89,"isPrimary":15,"meaningOrder":17},"01a13173-39af-76a1-ad93-73b2cf2982c3","NOUN","指早晨吃的点心或简单的饭食，即早餐，多见于口语或方言。","楼下有一家早点铺，豆浆和油条都很好吃。\n他每天上班前都在路边买一份早点。\n妈妈已经把早点准备好了，快来吃吧。","\u002Fuploads\u002Faudio\u002Ftts_dffc5c9b5b082c7c_zh-CN.mp3",4,{"id":93,"vocabularyWord":94,"displayOrder":105},"01a0e1ae-194c-746a-a5d6-05ea789a4833",{"id":95,"word":96,"frequency":30,"level":97,"language":9,"audioFilePath":98,"partsOfSpeech":99,"audio":38,"audioUrl":104},"01a0e1ad-ebee-7b9b-9312-f7b7544824f0","先","A1","tts_3cbe5b4095737722_zh-CN.mp3",[100],{"id":101,"partOfSpeech":82,"definition":102,"exampleSentences":103,"isPrimary":38,"meaningOrder":39},"01a0e1ad-ec37-7569-8ce5-d552e325c520","表示某个动作或步骤在另一个动作之前进行。","请先洗手，再吃饭。","\u002Fuploads\u002Faudio\u002Ftts_3cbe5b4095737722_zh-CN.mp3",5,[],[108,118],{"@id":109,"@type":110,"id":111,"grammarPage":112,"title":113,"instructions":114,"displayOrder":16,"type":115,"questionCount":116,"blankCount":116,"isCompleted":15,"ogImageUrl":117},"\u002Fapi\u002Fgrammar_exercises\u002F01a0e1ad-de14-74fd-b665-fd1b4da927c7","GrammarExercise","01a0e1ad-de14-74fd-b665-fd1b4da927c7","\u002Fapi\u002Fgrammar_pages\u002F01a0e1ad-b7e5-7c02-a499-213089ea6a8d","建议、必要和否定说法","根据句子和对话的意思，选择合适的说法。","word_select",14,"\u002Fuploads\u002Fimages\u002Fgpimg_88854e99-28e3-4930-85c0-edd52995ae9b_hero.webp?v=1790492663",{"@id":119,"@type":110,"id":120,"grammarPage":112,"title":121,"instructions":122,"displayOrder":39,"type":123,"questionCount":91,"blankCount":16,"isCompleted":15,"ogImageUrl":124},"\u002Fapi\u002Fgrammar_exercises\u002F01a0e1ad-de31-71dc-a0a0-ede8f25ae625","01a0e1ad-de31-71dc-a0a0-ede8f25ae625","应该、得、不应该和不用：按意思分类","点选句子，再点选对应的类别。把所有句子放好。","word_sort","\u002Fuploads\u002Fimages\u002Fgpimg_b8d5f2aa-f506-4a56-a01c-b0037d6ebeb9_hero.webp?v=1790492663",null]
