Unit 1+Unit 2（月考易错卷） - 2025-2026学年译林版2024七年级上学期英语

一、单项填空 1. 答案：C 解析：“would like to do sth.”是固定搭配，意为“想要做某事”，所以第一空填“to play”；“like doing sth.”表示“喜欢做某事”，强调爱好、习惯，这里说喜欢踢足球，是一种爱好，第二空填“playing” 。 2. 答案：C 解析：“with glasses”表示“戴着眼镜”，在句中作后置定语修饰“the girl” 。“wear”是动词，一个简单句中不能有两个谓语动词（没有连词连接的情况下），所以A、D错误；“in”表示“穿着”时，后常接颜色或衣服，不接“glasses”，B错误。 3. 答案：B 解析：“both”表示“两者都”，放在be动词之后，实义动词之前，“my parents”是两个人，所以用“are both” ；“all”表示“三者或三者以上都”，“we”指我和妹妹两个人，用“both”，“both”放在实义动词“love”之前 。 4. 答案：B 解析：“go by”有“被叫做”的意思，“I go by Millie.”意思是“我叫米莉”。“go on”意为“继续”；“go for”意为“选择；适用于” ；“go to”意为“去（某地）”，均不符合语境。 5. 答案：D 解析：“in the English Club”表示“在英语俱乐部”，“Tom”是第三人称单数，前面用be动词“Is”来提问；根据答句中“but”可知，后面表示转折，意思是他不常去，“go”是实义动词，否定句要借助助动词“doesn't” 。 6. 答案：C 解析：“one...the other...”表示“（两者中的）一个……另一个……”，这里说他有两个笔友，一个来自美国，另一个是中国人，用“the other” 。“the others”表示“其余的（表示在一个范围内的其他全部）”；“other”表示“其他的”，后常接可数名词复数；“others”表示“其他的人或物”，相当于“other +可数名词复数” 。 7. 答案：C 解析：“with his classmates”是伴随状语，句子的主语是“The boy”，是第三人称单数，“often”表明时态是一般现在时，所以谓语动词用第三人称单数形式“flies” 。 8. 答案：A 解析：“Lily”是第三人称单数，一般现在时中谓语动词用第三人称单数形式，“help”的第三人称单数是“helps”；“help sb. (to) do sth.”表示“帮助某人做某事”，所以第二空用动词原形“clean”（“to”可省略）。 9. 答案：C 解析：“be from = come from”表示“来自”，“your cousin”是第三人称单数，“come from”是实义动词短语，变疑问句要借助助动词“does”，后面动词用原形，所以选“does; come from” 。若用“be from”，则应该是“Where is your cousin from?” 。 10. 答案：D 解析：“hope”后不能直接接“sb. to do sth.”，A错误；“my best friend”是第三人称单数，B选项“come”是原形，错误；“coming”是现在分词形式，不能直接跟在“hope”后，C错误；“hope + (that)从句”，“can come”构成从句谓语，“我希望我最好的朋友下周日能来参加我的生日派对”，D正确。 11. 答案：B 解析：第一个“like”是介词，“be like”表示“像”，这里说西蒙像他爸爸，用“is like”；第二个“like”是动词，意为“喜欢”，主语“Simon”是第三人称单数，一般现在时中动词用第三人称单数形式“likes” 。 12. 答案：A 解析：“Why not do sth.?”是固定句型，意为“为什么不做某事呢？”，用来提出建议，所以用动词原形“join” 。 13. 答案：B 解析：根据答句“Every day.”（每天）可知，问句是对频率进行提问。“How many”提问可数名词的数量；“How often”提问频率；“How much”提问不可数名词的数量或价格；“How far”提问距离，所以选“How often” 。 14. 答案：B 解析：“all kinds of”表示“各种各样的”，后接可数名词复数，“books”是复数，所以用“all kinds of” 。“a kind of”表示“一种”，后接可数名词单数或不可数名词；C选项“a kinds of”表达错误；D选项“all kind of”表达错误。 15. 答案：A 解析：“Let’s...”句型用来提出建议，“That sounds good.”（听起来不错）是对建议的肯定回应 。“Thank you.”用于表达感谢；“Yes, please.”常用于回答“Would you like...?”等表示请求的句型；“No, I don’t”用于回答以“Do you...”开头的一般疑问句，均不符合语境。 二、完形填空 16. 答案：B 解析：“Here are...”是固定句型，意为“这里有……”，用于介绍或展示某物，符合语境，“Now”（现在）、“Not”（不）、“Well”（好；嗯）均不符合。 17. 答案：D 解析：根据后文“They are Linda and Jane. We are in the same school.”以及描述的她们之间的关系可知，她们是朋友，“aunts”（阿姨）、“brothers”（兄弟）、“uncles”（叔叔）均不符合。 18. 答案：C 解析：这里说的是简的电话号码，简是女孩，所以用形容词性物主代词“Her” 。“His”（他的）用于男性；“My”（我的）；“Your”（你的）均不符合。 19. 答案：B 解析：根据常识，山姆是妈妈的兄弟，“grandfather”（祖父）、“father”（父亲）、“son”（儿子）均不符合。 20. 答案：A 解析：根据后文“The boy is their son Jack...the girl is their daughter Alice.”可知，叔叔和阿姨有两个孩子。 21. 答案：C 解析：“The boy is their son Jack”和“the girl is their daughter Alice”是并列关系，用“and”连接 。“to”（到；向）；“of”（……的）；“too”（也）均不符合。 22. 答案：C 解析：前文提到了第一张照片和下一张照片，这里说的是最后一张照片，“last”表示“最后的” 。“first”（第一）；“two”（二）；“middle”（中间的）均不符合。 23. 答案：D 解析：根据后文“She is 80 years old. She is my father’s mother.”可知，她是我的祖母，“mother”（母亲）、“daughter”（女儿）、“cousin”（表兄弟姐妹）均不符合。 24. 答案：A 解析：根据后文“The baby is my little sister Ada.”可知，这里是问婴儿是谁，用“Who”提问 。“What”（什么）；“What color”（什么颜色）；“How”（怎样）均不符合。 25. 答案：B 解析：这里是问能不能在照片里看到“我”，“see”表示“看见” 。“say”（说）；“meet”（遇见）；“phone”（打电话）均不符合。 三、阅读理解 26. 答案：A 解析：根据文中“In China, many grandmothers enjoy dancing in public squares. Some also enjoy playing mahjong.”可知，中国老年女性流行的爱好有在广场跳舞和打麻将，所以选A。 27. 答案：C 解析：文中提到“Older men often get together in parks and play Chinese chess.”，所以中国老年男性经常在公园下中国象棋，选C。 28. 答案：C 解析：文中提到美国老年人的爱好有“playing cards”（打牌）、“gardening”（园艺）、“baking”（烘焙），未提及在广场跳舞，选C。 29. 答案：B 解析：根据“Gardening gives them fresh air and exercise, and they can grow vegetables or flowers.”可知，园艺能给他们新鲜空气和锻炼，选B。 30. 答案：D 解析：文章第一段总述世界各地老年人有不同爱好，这些爱好使他们生活有趣；第二、三段分别介绍中国和美国老年人的爱好；第四段总结爱好对老年人的重要性。所以文章结构是“总 分 总”，选D。 31. 答案：C 解析：根据文中“I get up at 6:50 a.m. I take a shower after getting up.”可知，海伦早上起床后先洗澡，选C。 32. 答案：A 解析：文中提到“I join the school swimming club.”，所以海伦在学校的游泳俱乐部，选A。 33. 答案：B 解析：根据“There are three classes in the morning.”和“There are two classes in the afternoon.”可知，海伦一天有3 + 2 = 5节课，选B。 34. 答案：C 解析：文中说“School is over at 5 o’clock. I usually swim for an hour after school. Then I go home.”，5点放学，游泳1小时后回家，所以通常6点回家，选C。 35. 答案：D 解析：根据“Sunday is my favorite day. I see my grandparents.”可知，海伦周日去看望祖父母，选D。 36. 答案：B 解析：从文中“There is a wonderful farm near the sports field in our school.”可知，快乐学校农场在运动场附近，选B。 37. 答案：C 解析：文中提到“Every Tuesday and Friday, we work on the farm after class.”，所以学生每周二和周五课后在农场劳动，选C。 38. 答案：B 解析：“day by day”意思是日复一日，形容每天都这样，时间一天天过去，选B。 39. 答案：B 解析：根据“In art class, we draw beautiful pictures of the vegetables and show them to our classmates.”可知，在美术课上学生画蔬菜的画，选B。 40. 答案：C 解析：文章主要介绍了快乐学校农场，学生在农场劳动、学习，还能在不同课程中借助农场进行有趣的学习活动，所以文章主要讲农场如何帮助学生学习和获得乐趣，选C。 四、填空 A) 41. 答案：to say 解析：“have to do sth.”表示“不得不做某事”，所以用“to say” 。 42. 答案：members 解析：“family member”表示“家庭成员”，这里指家庭成员们，用复数形式“members” 。 43. 答案：in 解析：在年份前用介词“in”，“in 1973”表示“在1973年”。 44. 答案：difference 解析：“make a difference”是固定短语，意为“有影响；起作用”，用名词“difference” 。 45. 答案：better 解析：根据“than before”可知，这里用比较级，“good”的比较级是“better” 。 46. 答案：But 解析：前文说在中国人们见面说“你好”，后文说在说英语的国家人们如何打招呼，前后是转折关系，用“But” 。 47. 答案：usually 解析：这里用副词修饰动词“ask”，“usual”的副词形式是“usually”（通常）。 48. 答案：plans 解析：“any”表示“一些”，用于疑问句和否定句中，后接可数名词复数，“plan”的复数是“plans” 。 49. 答案：a 解析：“question”是可数名词单数，这里表示泛指“一个问题”，用不定冠词“a” 。 50. 答案：boys 解析：“among”表示“在……之间（三者或三者以上）”，后接可数名词复数，“boy”的复数是“boys” 。 B) 51. 答案：volleyball club; heroes; of; hers 解析：“排球俱乐部”是“volleyball club”；“榜样”是“hero”，“one of +可数名词复数”表示“……之一”，所以用“heroes”；“她的榜样之一”用“one of her heroes”，也可以用双重所有格“one of the heroes of hers” 。 52. 答案：works; of; master 解析：“作品”用“works”（常用复数形式）；“……的作品”用“the works of...”；“大师”是“master” 。 53. 答案：In; this; way 解析：“用这种方法”是固定短语“In this way” 。 54. 答案：take; things; apart 解析：“take sth. apart”表示“拆开某物”，“like to do sth.”后用动词原形，所以是“take things apart” 。 55. 答案：ready; to; help; others 解析：“be ready to do sth.”表示“乐于做某事”；“帮助别人”是“help others” 。 五、阅读填空 56. 答案：Students need 100 blue tickets to get a new book. 解析：文中提到“If you have ten blue tickets, you can get a red one. If you have ten red tickets, you can get a yellow one. If you have ten yellow tickets, you can get a new book.”，10张蓝票换1张红票，10张红票换1张黄票，10张黄票换一本新书，所以10×10×10 = 100，需要100张蓝票才能得到一本新书。 57. 答案：Yes, he does. 解析：文中提到“Finally, he has enough to get a new book.”，说明汤姆得到了一本新书，所以是肯定回答。 58. 答案：Everyone feels very surprised. 解析：根据“Tom stands up and everybody is very surprised to see he has enough tickets.”可知，汤姆站起来时，每个人都感到非常惊讶。 59. 答案：Mr White is a great judge. 解析：从文中“Her father, a great judge, comes too. The girl is Becky White.”可知，怀特先生是一位伟大的法官。 60. 答案：He may study harder.（答案不唯一，合理即可） 解析：汤姆在法官面前回答不出作业问题，之后他可能会意识到自己学习方面的不足，从而更加努力学习。这是一种合理推测，其他合理答案如他可能会更认真对待作业等也可。 六、书面表达（仅供参考） Hello, everyone!
