单选题 In (the early) grades, the academic performance of girls (are) equal to (that) of boys in math and (almost) equal to boys in science.
  • A. the early
  • B. are
  • C. that
  • D. almost


【正确答案】 B
【答案解析】将are改为is。这句话的主语是performance,而不是girls,故谓语应当用单数。该句话的意思是,“在低年级,女孩子在数学方面的学习能力与男孩子是相等的,而在其他学科方面与男孩子几乎相同”。
