  215.
  Rock samples taken from the remains of an asteroid about twice the size of
 the 6-mile-wide asteroid that eradicated the dinosaurs has been dated to be
 3.47 billion years old and thus is evidence of the earliest known asteroid
 impact on Earth.

  A. has been dated to be 3.47 billion years old and thus is
  B. has been dated at 3.47 billion years old and thus
  C. have been dated to be 3.47 billion years old and thus are
  D. have been dated as being 3.47 billion years old and thus
  E. have been dated at 3.47 billion years old and thus are


  答案是E

  我選了C 因為印象中dated at + n.       ex: dated at 1000 BC
                    dated to be + adj.  ex: dated to be 1000 years old

  檢討的時候對照了CD上面下載的SC考點總結(955精華版)上面也是這樣寫的

  請問正確的用法究竟是哪一個呢

  謝謝

推 Calla:這題gmat http://gmatclub.com/forum/sloth-80744.html
→ Calla:剛好也用到"dated at"但每個選項都是接XXX years old
→ Calla:同時google "dated at"也能找到很多文章(eg: amazon river
→ Calla:dated at 11 million years old" 看來idiom "dated at"
→ Calla:後面是可以接 years old的... 不然第一個連結的選項就都錯了
推 Vierro:如果兩者用法都正確 請選擇較簡潔的~因此at +N比to be+N好
推 Vierro:AT有時候答案文法都對的時候要選擇簡潔的@@~
→ hann1011:嗯嗯  我也是google之後發現有at+years old的用法
→ hann1011:但又覺得很奇怪 因為一般介詞後面不是要接名詞嗎...
→ hann1011:at + years "old" 卻是形容詞  讓我很疑惑 >"<
推 Calla:可能只是慣用語法吧? XD 這種東西只能憑fu了 (拍拍)
→ krystal0331:at ,to都可以,是錯在那個be. (be在此無任何作用)
