解析

本题主要考查基数词的英文表达以及基数词在不同语境中的正确用法。

一、基数词填空

  1. 对于 13，其英文表达是“thirteen”。
  2. 15 的英文是“fifteen”。
  3. 18 对应的英文为“eighteen”。
  4. 20 用英文表示是“twenty”。
  5. 30 的英文表达是“thirty”。
  6. 40 英文是“forty”。
  7. 50 对应的英文为“fifty”。
  8. 80 用英文表示是“eighty”。
  9. 35 是由 30 和 5 组成，英文表达为“thirty - five”。
  10. 21 是由 20 和 1 组成，英文是“twenty - one”。

二、单项选择

  1. “There are ____ students in our class.” 这里需要表达“35 名学生”，在英语中，当表示具体的几十几的数字时，要用连字符连接十位和个位，即“thirty - five”。A 选项“thirty five”缺少连字符；B 选项“thirty fifth”是序数词“第三十五”；C 选项“thirty - fifth”也是序数词形式，所以答案选 D。
  2. “My sister is ____ years old.” 表示“某人多少岁”要用基数词，“12 岁”就是“twelve years old”，B 选项“twelfth”是序数词“第十二”；C 选项“the twelve”表述错误；D 选项“the twelfth”同样是序数词形式，所以答案选 A。
  3. “He will stay here for ____.” “三周”的正确表达是“three weeks”，A 选项“three week”中 week 应该用复数形式；C 选项“three - weeks”这种表达错误，复合形容词中名词要用单数；D 选项“three week's”表述错误，所以答案选 B。
  4. “____ people are in the park on weekends.” 表示“数百”要用“hundreds of”，A 选项“Hundred of”缺少 s；B 选项“Hundreds”单独使用不能表示“数百”的意思；D 选项“Hundred”表示具体的“一百”，所以答案选 C。
  5. “The ____ girl is my cousin.” 这里需要一个复合形容词来修饰“girl”，复合形容词的结构是“数词 - 名词（单数） - 形容词”，所以“八岁的”是“eight - year - old”，A 选项“eight - years - old”中 year 应该用单数；C 选项“eight year old”不能直接作定语修饰名词；D 选项“eight years old”通常作表语，所以答案选 B。
  6. “My father is in ____ now.” 表示“某人四十多岁”要用“in one's forties”，A 选项“his forty”表述错误；B 选项“the forties”缺少所有格；C 选项“the forty”表述错误，所以答案选 D。
  7. “There are ____ books in the library.” “两千”是“two thousand”，当 thousand 前面有具体数字时，用单数形式，且后面接名词时不需要“of”，B 选项“two thousands”中 thousand 应该用单数；C 选项“two thousand of”表述错误；D 选项“two thousands of”同样错误，所以答案选 A。
  8. “We have a ____ holiday.” 这里需要一个复合形容词来修饰“holiday”，复合形容词的结构是“数词 - 名词（单数） - 形容词”，所以“五天的”是“five - day”，A 选项“five - days”中 days 应该用单数；B 选项“five day”表述错误；D 选项“five days”通常作表语，所以答案选 C。
