请教一道托福语法试题:
Of the 300 languages that were once spoken by Native American people,
an extimated _____ today.
(A) exist 150
(B) 150 exist
(C) there are 150
(D) exesting are 150:
正确的答案是(B),但是我不明白为什么(B)选项的后没有‘s’: 根据我的理解,本题的句式是:an ****** does。前面有了冠词an,而: 从时态看是单数,而从答案看是复数,为什么?请指教,谢谢!
B作为正确答案是毫无疑问的。我觉得可以将an看作是对extimated 的修饰,表示一种估计。这样的分析是不是合理欢迎再讨论。
