2026—2027学年人教版八上 Unit 1～4 语法易错拔高专项（含答案） 适用教材：人教版（2025）英语八年级上册 Unit 1～Unit 4 开学头四个单元的语法点看着简单，实际考试里学生丢分的地方往往很集中：复合不定代词作主语时谓语用单数、形容词修饰不定代词要放后面；could 表过去能力和礼貌请求的答语；比较级里多余的双比较；最高级前漏掉 the。这份专项就把这些易错点挑出来，用改错、填空、选择和句型转换几种方式反复练，最后配了一篇跨单元的小短文把前面四个单元的语法串起来。 一、Unit 1 Happy Holiday：复合不定代词与一般过去时 （一）改正下列句子中的错误 1.

Everyone are → Everyone is。复合不定代词 everyone 作主语时，谓语动词用单数形式。 2. Did you bought → Did you buy。一般过去时的疑问句用助动词 did，后面的动词用原形。 3. anything fun → something fun。肯定句中表示“某物”用 something；形容词 fun 修饰不定代词要放在后面。 4. is　5. knows　6. anything 4. 复合不定代词 everything 作主语，谓语用单数。5. nobody 表示“没有人”，作主语谓语用单数。6. 否定句中用 anything，与句末的 empty 呼应。 7. A。表示请求、希望对方肯定回答时，用 something 而不用 anything。 8. C。从“我们只好在外面等”可知教室里没有人，nobody 表示“没有人”。 9. C。last summer 是过去的时间，用一般过去时 had。 10. B。yesterday 提示一般过去时，一般疑问句用 Did 开头。 11. I didn't buy any postcards for my friends. 12. What did he do last weekend? 11. 否定句中 some 要改为 any。12. 对“做的事”提问用 What did...do。 二、Unit 2 Home Sweet Home 13. I can swim → I could swim。表示过去的能力用 could，不是 can。 14. 答语应改为 Yes, sure. 或 Of course.。Could you...? 表示礼貌请求，肯定回答不用 could，要用 sure、of course 等。 15. keeps → kept。last month 是过去的时间，keep 的过去式是 kept。 16. couldn't（年轻时不会骑车，但现在会，过去能力用 could 的否定式） 17. keep（keep 表示“借阅一段时间”，可以和 for three days 搭配） 18. Could 或 May（礼貌请求许可，答语是 Sure, here you are） 19. D。Could I...? 表示请求许可，肯定答语用 Sure, go ahead. 等，不用 could 回答。 20. B。when he was seven 表示过去，过去的“能”用 could。 21. A。not...until 表示“直到……才”，“车停稳之前别下车”。 22. C。问借书借多久用 How long can I keep...?，borrow 是短暂性动词。 23. I couldn't cook dinner when I was ten. 24. Sure. / Of course. / No problem. 23. could 的否定式是 couldn't。24. Could you please...? 的肯定回答用 Sure 等，不用 could。 三、Unit 3 Same or Different? 25. more taller → taller。tall 是单音节形容词，比较级直接加 -er，不能和 more 连用。 26. as tall than → as tall as。as...as 中间用原级，表示“和……一样……”。 27. more interesting as → more interesting than。比较级后接 than，不接 as。 28. easier　29. more carefully　30. better 28. easy 是辅音字母加 y 结尾，变比较级去 y 加 -ier。29. carefully 是多音节副词，比较级用 more carefully。30. much 修饰比较级，good 的比较级是 better。 31. A。outgoing 是多音节形容词，比较级用 more outgoing；than 提示用比较级。 32. B。much 可以修饰比较级，表示“贵得多”。 33. A。as...as 中间用原级 important。 34. B。两个人比较用比较级，taller。 35. That book is more interesting than this one. 36. Tom is taller than any other boy in his class. 35. “这本书不如那本有趣”也就是“那本比这本有趣”。36. “最高级”与“比较级+than any other”可以互换。 四、Unit 4 Amazing Plants and Animals 37. highest → the highest。形容词最高级前要加定冠词 the。 38. the tallest → the taller。“两者之中较……的一个”用 the + 比较级。 39. more beautiful → the most beautiful。在花园这个范围里用最高级，形容词最高级要加 the。 40. tallest　41. best　42. most beautiful 40. 在世界上这个范围里长颈鹿最高。41. of all the subjects 是最高级范围，good 的最高级是 best。42. one of the + 最高级 + 复数名词，beautiful 是多音节形容词。 43. A。从“大象”这个回答看，问的是“这些动物中哪一个最大”，用 Which of these animals。 44. C。一年中最好的季节用最高级 best。 45. A。I have ever seen 提示最高级，最高级前加 the。 46. D。跳得最高是副词最高级，加 the 更正式，也可写 highest。 47. Wang Ping is the tallest student in his class. 48. Li Lei is the tallest student in our class. 47. “比其他学生高”等于“全班最高”。48. “没有人比他高”等于“他是最高的”。 五、综合运用 49. has（everyone 作主语，谓语用单数） 50. visited（last year 用一般过去时） 51. most wonderful（one of the + 最高级 + 复数名词） 52. is（nothing 作主语，谓语用单数） 53. harder（than before 提示比较级） 54. best（the + 最高级，good 的最高级是 best） 短文大意：我们班每个人都有梦想。去年我和父母去了长城，它是世界上最神奇的地方之一。爸爸告诉我，只要尽力，就没有什么是难的。现在我比以前学习更努力，我想成为班里最好的学生。 学科网（北京）股份有限公司 $
