题目解答
答案
本题考察“class”作为集体名词的单复数用法。根据“Miss Gao teaches them”,“them”指“students”,说明“class”表个体成员,应为复数。前半句需用“are studying”表现在进行时。选项B“is”不符,C和D语法错误。综合分析,正确答案为A。
答案:A. are studying
解析
本题考查集体名词“class”的单复数用法。关键点在于判断“class”在句中表示整体还是个体成员:
- 当“class”表示班级整体时,动词用单数(如:The class is very quiet.)
- 当“class”表示班级中的学生(个体成员)时,动词用复数(如:The class are talking loudly.)
解题核心:通过后文“Miss Gao teaches them”中的“them”指代学生,推断“class”在此处表示学生群体,需用复数形式。
句子分析
-
确定主语和时态
句子主干为“This class ___ now”,空处需填入现在进行时的动词形式(be + 动词-ing)。 -
判断“class”的单复数
后文“Miss Gao teaches them”中的“them”指代“学生”,说明前文的“class”强调班级中的学生个体,因此需用复数形式“are studying”。 -
排除错误选项
- B. is studying:误用单数,与“them”矛盾
- C. be studying:缺少主谓一致(复数应为“are”)
- D. studying:缺少助动词“be”
