You ____ finish your homework before you play video games with your friends. A. has better B. had better C. had better to D. have better 【答案】B 【知识点】had better + 动词原形表示最好做某事 【解析】正确答案是B. had better。had better是固定短语，后接动词原形，表示“最好做某事”，且不随主语变化；主语是you，所以用had better。A项has better主谓不一致；C项had better to多加了to；D项have better不是正确搭配。 2. You ____ eat too much ice cream before dinner, or you will have a stomachache. A. had better not to B. hadn't better C. had better not D. didn't better 【答案】C 【知识点】had better not + 动词原形表示最好不要做某事 【解析】正确答案是C. had better not。had better not是had better的否定形式，后接动词原形，表示“最好不要做某事”。A项had better not to多加了to；B项hadn't better否定形式错误；D项didn't better结构错误。 3. You needn't ____ any money with you because the tickets are free for students. A. to bring B. bringing C. brought D. bring 【答案】D 【知识点】need 作情态动词时用于否定和疑问，后接动词原形 【解析】正确答案是D. bring。need作情态动词时，否定形式needn't后接动词原形。A项to bring多加了to；B项bringing是现在分词；C项brought是过去式，均不能用于needn't之后。 4. She needs ____ her room before she goes out to play with her friends. A. to clean B. clean C. cleaning D. cleaned 【答案】A 【知识点】need 作实义动词时常用 need to do 结构 【解析】正确答案是A. to clean。need作实义动词时，后接动词不定式to do，主语she是第三人称单数，needs后要跟to do。B项clean缺少to，是情态动词need的用法；C项cleaning是need doing结构，通常表示被动含义，且主语应为人；D项cleaned是过去式，不符合。 5. He ____ take the medicine after meals as the doctor told him to do. A. has better B. had better C. had better to D. have better 【答案】B 【知识点】had better + 动词原形表示最好做某事 【解析】正确答案是B. had better。had better后接动词原形，表示“最好做某事”，且不随主语变化，主语he也用had better。A项has better主谓不一致；C项had better to多加了to；D项have better不是正确搭配。 6. You ____ stay up too late tonight, or you will be very tired tomorrow morning. A. had better not B. needn't C. can D. must 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】答案 A。had better not 表示“最好不要做某事”，符合语境“今晚不要熬夜，否则明天早上会很累”。needn't 表示“不需要”，can 表示“可以”，must 表示“必须”，均不符合句意。 7. My younger brother ____ swim very well, so he often helps me in the pool. A. can B. need C. needn't D. had better 【答案】A 【知识点】can 表示能力或可以做某事，后接动词原形；注意与 need 作情态动词的否定和疑问用法辨析，need 肯定句通常用 need to do 作实义动词。 【解析】答案 A。can 表示能力，意为“能、会”，符合“游泳游得很好”的语境。need 作情态动词通常用于否定和疑问句，肯定句应用 need to do；needn't 表示“不需要”；had better 表示“最好”，均不合句意。 8. You really ____ practice more if you want to win the singing competition next month. A. need to B. need C. needs to D. needn't 【答案】A 【知识点】need 作实义动词时常用 need to do 结构 【解析】答案 A。need to do 是 need 作实义动词的固定结构，主语 you 后接 need to practice，表示“需要练习”。need 是情态动词，通常用于否定和疑问句，且后接动词原形；needs to 主语应为第三人称单数；needn't 表示“不需要”，与句意相反。 9. All students ____ wear school uniforms from Monday to Friday during school hours. A. must B. had better C. had better not D. needn't 【答案】A 【知识点】must 表示必须或强制要求；与 had better 表示最好做某事（建议）进行辨析，本单元目标 had better + 动词原形表示最好做某事，但此处语境为强制规则，故用 must。 【解析】答案 A。must 表示“必须”，符合校规强制要求。had better 表示“最好”，语气较弱；had better not 表示“最好不要”；needn't 表示“不需要”，均不符合强制规则语境。 10. You ____ eat too much ice cream because it is bad for your stomach. A. had better not B. needn't C. must D. can 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】答案 A。had better not 表示“最好不要做某事”，符合语境。needn't 表示“不需要”；must 表示“必须”；can 表示“可以”，均不合句意。 11. Sarah ____ finish her project by Friday, or she will miss the important deadline. A. needs B. need C. must D. musts 【答案】C 【知识点】情态动词（如must）没有第三人称单数变化，后接动词原形；对比need作情态动词多用于否定和疑问。 【解析】must是情态动词，情态动词没有单数第三人称形式变化，且后接动词原形finish，因此C正确。A项needs是实义动词，主语Sarah为单数，若用实义动词应为needs to finish，但空格后直接是finish，故A错；B项need作情态动词多用于否定和疑问，肯定句不常用；D项musts不存在，情态动词不加-s。 12. She ____ her room every weekend because her parents ask her to keep it clean. A. need to clean B. needs to clean C. need clean D. needs clean 【答案】B 【知识点】need作实义动词时常用need to do结构，第三人称单数用needs to do。 【解析】B项needs to clean中needs是实义动词，主语She为单数，所以needs后有to do，正确。A项need to clean缺第三人称单数；C项need clean是情态动词need的用法，但肯定句不用；D项needs clean缺少to，实义动词后不能直接接动词原形。 13. My brother ____ swim very well when he was only five years old. A. had better B. could C. can D. had better to 【答案】B 【知识点】could表示过去的能力，是can的过去式，后接动词原形；对比had better+动词原形表示最好做某事，但此处需表达过去能力。 【解析】B项could是can的过去式，表示过去的能力，符合“when he was only five years old”的过去语境，后接动词原形swim，正确。A项had better表示“最好”，语义不符，且无过去时；C项can表示现在能力，时态错误；D项had better to结构错误，had better后应接动词原形。 14. You ____ go to bed late tonight because you have an exam tomorrow. A. had better not B. had better not to C. had not better D. had better don't 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事。 【解析】A项had better not后接动词原形go，构成正确否定形式；B项多to，had better后不加to；C项not位置错误，应为had better not；D项had better后面不能接助动词don't，应直接接not+动词原形。 15. ____ I use your phone for a moment? I need to call my mother. A. Need B. May C. Must D. Do 【答案】B 【知识点】may表示请求许可，后接动词原形；对比need作情态动词用于疑问句时表示必要性，不用于请求许可。 【解析】B项May表示请求许可，符合语境“I use your phone...”；A项Need作情态动词用于疑问时通常询问必要性，意为“需要”，此处是请求许可，语义不当；C项Must表示必须，语气过强，不合请求语境；D项Do是助动词，但此处用Do开头则应为Do I use...，结构不同，且请求许可用May更自然。 16. My little brother ____ his room before he can go out to play. A. need to clean B. needs to clean C. need clean D. needs clean 【答案】B 【知识点】need 作实义动词时常用 need to do 结构；主语为第三人称单数时用 needs to do 【解析】need 作实义动词时后面接带 to 的不定式，且主语 my little brother 是第三人称单数，所以要用 needs to clean。选项 A need to clean 没有按第三人称单数加 -s；选项 C need clean 是情态动词 need 的用法，但情态动词 need 通常用于否定句和疑问句，不用于肯定句；选项 D needs clean 缺少不定式符号 to。 17. You ____ tell the teacher if you see someone cheating in the exam. A. had better B. must C. have to D. need to 【答案】B 【知识点】must 表示主观道义上的责任（must, have to 和 need）；与 had better 表示建议进行辨析 【解析】这里表达的是看到考试作弊必须报告老师的责任，must 强调主观道义上的责任，最符合语境。选项 A had better 表示“最好做某事”，语气是建议而非责任；选项 C have to 强调客观上的不得不，不如 must 表达主观责任强烈；选项 D need to 表示“需要”，同样没有 must 那种责任义。 18. You ____ play with fire in the kitchen because it is very dangerous. A. had better not B. had not better C. had better not to D. hadn't better 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】had better 的否定形式是在 had better 后面加 not，即 had better not，后接动词原形。选项 B had not better 语序错误；选项 C had better not to 多加了 to；选项 D hadn't better 不是规范的否定形式，通常不说 hadn't better。 19. ____ we meet at the school gate at eight o'clock tomorrow morning? A. Shall B. Need C. Will D. Would 【答案】A 【知识点】shall 表示建议（shall, will 和 would）；与 need 作情态动词用于疑问句进行辨析 【解析】Shall we... 是常见的表示建议的句型，用于征求对方意见。选项 B Need 作情态动词时也可以用于疑问句，但 Need we meet? 意思是“我们需要见面吗？”，语义上是询问必要性，而不是提出建议；选项 C Will we meet? 是询问将来的事实，不是建议；选项 D Would we meet? 通常不用于第一人称复数提出建议，Would you... 才是请求。 20. She ____ her homework before she can watch her favourite cartoon on television. A. need to finish B. needs to finish C. need finish D. needs finish 【答案】B 【知识点】need 作实义动词时常用 need to do 结构；主语为第三人称单数时用 needs to do 【解析】need 作实义动词时后接带 to 的不定式，主语 she 是第三人称单数，所以动词用 needs。选项 A need to finish 没有加 -s；选项 C need finish 是情态动词用法，但情态动词 need 通常用于否定和疑问；选项 D needs finish 缺少 to。 21. Every student ____ obey the school rules, because they are important for safety. A. had better B. should C. need D. can't 【答案】B 【知识点】should/ought to 表示义务责任，与 had better 表示最好做某事进行辨析 【解析】句意为“每个学生都应该遵守校规，因为它们对安全很重要。”表示不可推卸的义务，应用 should。A项 had better 语气过强，多用于警告特定后果，不如 should 适合此处；C项 need 作实义动词需接 to do，作情态动词一般不用于肯定句，且语义不符；D项 can't 表示不能，与句意相反。 22. You have a fever, so you ____ go to school today and need to rest at home. A. had better not B. had better not to C. had better don't D. hadn't better 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】句意为“你发烧了，所以你今天最好不要去上学，需要在家休息。”had better not 后接动词原形，A正确。B项多了 to，C项将否定放在助动词上，D项 hadn't better 结构错误，均不符合语法规则。 23. When I was a child, I ____ climb trees in the park near my home. A. used to B. need to C. needn't D. didn't need to 【答案】A 【知识点】used to 表示过去习惯，与 need 作情态动词用于否定和疑问进行辨析 【解析】句意为“我小时候常常在家附近的公园爬树。”表示过去习惯用 used to，A正确。B项 need to 表示现在需要，不符合过去时间；C项 needn't 表示不必，语气不符；D项 didn't need to 表示过去不必，不是过去习惯。 24. Before dinner, we ____ buy some food because the fridge is almost empty now. A. need to B. need C. need of D. needs to 【答案】A 【知识点】need 作实义动词时常用 need to do 结构 【解析】句意为“晚饭前我们需要买些食物，因为冰箱现在几乎空了。”need 作实义动词后接 to do，主语 we 用原形，A正确。B项 need 后直接接动词原形，是情态动词用法，但情态动词多用于否定和疑问，且此处需表示实义动词的“需要”；C项 need of 搭配错误；D项 needs to 是第三人称单数，与主语 we 不一致。 25. My brother ____ fix computers very well, so he often helps his friends. A. can B. had better C. need D. may 【答案】A 【知识点】can 表示能力，与 had better 表示最好做某事进行辨析 【解析】句意为“我哥哥很会修电脑，所以他经常帮助他的朋友。”表示能力用 can，A正确。B项 had better 意为最好做某事，表示建议，不符合此处对能力的描述；C项 need 作实义动词需接 to do，作情态动词不用于此肯定句；D项 may 表示许可或可能，能力不及 can 准确。 26. You have a test tomorrow, so you had better ____ video games tonight. A. not play B. not to play C. don't play D. not playing 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】had better not 后接动词原形，表示“最好不要做某事”，所以 not play 正确。not to play 是不定式否定形式；don't play 是祈使句否定；not playing 是现在分词，均不符合 had better not 的结构要求。 27. The sign over there says no parking, so you ____ park your car here. A. mustn't B. needn't C. don't D. can't 【答案】A 【知识点】The imperative / Modal verb: must, mustn't（mustn't 表示禁止做某事）；与 need 作情态动词（needn't 表示不需要）的辨析 【解析】根据标志“禁止停车”，此处应表示“禁止”，所以 mustn't 正确。needn't 表示“不需要”，意思不符；don't 后接动词原形构成否定祈使句，但本句主语是 you，且需要情态动词；can't 通常表示“不能（能力）”，这里强调规则禁止，mustn't 更恰当。 28. Since the math class starts at 8 a.m., I ____ my homework before dinner. A. need to finish B. need finish C. needs to finish D. need finishing 【答案】A 【知识点】need 作实义动词时常用 need to do 结构（主语 I 用 need，后接带 to 的不定式） 【解析】need 作实义动词时，后接带 to 的不定式，主语 I 用动词原形 need，所以 need to finish 正确。need finish 是情态动词用法，但 need 作情态动词多用于否定和疑问，肯定句中通常不用；needs to finish 用了第三人称单数，与主语 I 不符；need finishing 是 need doing 结构（主动表被动），但此处主语是人且需要主动完成，不合适。 29. You really ____ study harder if you want to pass the final exam. A. should B. should to C. had better to D. ought 【答案】A 【知识点】情态动词后接动词原形（情态动词不能单独使用，也不能后接带 to 的不定式）；与 had better + 动词原形结构辨析 【解析】情态动词 should 后接动词原形 study，表示“应该”，所以 should 正确。should to 中情态动词后多加 to；had better to 中 had better 后不应加 to（had better + 动词原形）；ought 通常需与 to 连用构成 ought to，不能单独使用，且后接动词原形，但此处空格后是 study，用 ought 则缺少 to，故错误。 30. It's raining heavily outside, so you had better ____ without an umbrella. A. not go B. not to go C. don't go D. not going 【答案】A 【知识点】had better not + 动词原形表示最好不要做某事 【解析】had better not 后接动词原形，表示“最好不要做某事”，所以 not go 正确。not to go 是不定式否定；don't go 是祈使句否定；not going 是现在分词，均不符合。 四、语法选择（共20分） （1） 请通读下面短文，掌握其大意，根据语法和上下文连贯的要求，从每小题所给的四个选项中选出一个最佳答案。 Lucy is a Grade 7 student.
