About two thirds of the students in our class is from the countryside. 【答案】is → are 【详解】考查分数与主谓一致。句意：我们班大约三分之二的学生来自农村。“分子为基数词，分母为序数词”表示分数，此处 two thirds 表示“三分之二”。“分数 + of + 可数名词复数（students）”作主语时，谓语动词应用复数形式，故将 is 改为 are。故答案为：is → are。 22. My young brother will celebrate his twelveth birthday next Monday. 【答案】twelveth → twelfth 【详解】考查序数词拼写。句意：我弟弟下周一将庆祝他的十二岁生日。基数词 twelve 变序数词时，需变 v 为 f 再加 -th，正确拼写为 twelfth。故答案为：twelveth → twelfth。 23. Thousands of visitors come to the park on May First every year. 【答案】First → 1st 【详解】考查日期的表达法。句意：每年五月一日有成千上万的游客来到这个公园。在英语中，表示几月几日时，月份后的日期常用阿拉伯数字加序数词后缀（如 1st, 2nd, 3rd 等）或直接用阿拉伯数字表达，此处五月一日应用 1st。故答案为：First → 1st。 24. There are hundreds of book in the school library. 【答案】book → books 【详解】考查数词固定短语。句意：学校图书馆里有数百本书。“hundreds of + 可数名词复数”为固定搭配，意为“数以百计的……”，of 后必须接可数名词复数形式。故答案为：book → books。 25. The teacher told us that page twenty-five was very important. 【答案】twenty-five → 25 【详解】考查页码的书写规范。句意：老师告诉我们第 25 页非常重要。在英语中，表示“第几页”通常用“Page + 阿拉伯数字”，并且 Page 需大写，数字用阿拉伯数字表达更符合规范。故答案为：twenty-five → 25。 26. It is said that two millions people attended the international concert last night. 【答案】millions → million 【详解】考查基数词修饰具体数量。句意：据说昨晚有两百万人参加了那场国际音乐会。当 million 前有具体基数词（如 two）修饰时，million 必须用单数形式，且后面不加 of。故答案为：millions → million。 27. This is the two time that our school has won the basketball match. 【答案】two → second 【详解】考查序数词。句意：这是我们学校第二次赢得篮球比赛。表示“第几次”应用序数词，在“It/This is the + 序数词 + time that...”句型中，应将基数词 two 改为序数词 second。故答案为：two → second。 28. The famous scientist was born in the 1980. 【答案】1980 → 1980s 【详解】考查年代表达法。句意：这位著名的科学家出生于 20 世纪 80 年代。表示“在……世纪……年代”用“in the + 年份s”，20世纪80年代应表达为 in the 1980s。故答案为：1980 → 1980s。 29. He was nine year old when he started learning to play the piano. 【答案】year → years 【详解】考查年龄表达法。句意：他开始学弹钢琴时只有九岁。表示“几岁”时，数字大于 1，名词 year 必须用复数形式 years，即“基数词 + years old”。故答案为：year → years。 30. Half of the apple were eaten by my little brother just now. 【答案】were → was 【详解】考查分数/部分表达与主谓一致。句意：这个苹果的一半刚才被我弟弟吃了。“Half of + 可数名词单数（apple）”作主语时，谓语动词应用单数形式，故将 were 改为 was。故答案为：were → was。 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
