There are many famous cultural relics in our country, many _______ thousands of years ago.
A．dating back toB．date back toC．dated back toD．were dated back to
A

試題分析：句意：我們國家有很多文化遺跡，很多要追溯到幾千年前。這里前面是簡單句，因為中間沒有連詞，所以逗號后面不是句子，而是獨立主格結(jié)構(gòu)，用邏輯主語+非謂語動詞構(gòu)成，因為date back to“追溯到”這個詞組沒有被動語態(tài)，所以用現(xiàn)在分詞，所以選A。
