請教一道托福語法試題:
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:
正確的答案是(B),但是我不明白為什么(B)選項的后沒有‘s’: 根據(jù)我的理解,本題的句式是:an ****** does。前面有了冠詞an,而: 從時態(tài)看是單數(shù),而從答案看是復數(shù),為什么?請指教,謝謝!
B作為正確答案是毫無疑問的。我覺得可以將an看作是對extimated 的修飾,表示一種估計。這樣的分析是不是合理歡迎再討論?! ?BR>
