85. Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that ?ourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates. (A) that ?urished at the same time as the civilizations (B) that had ?ourished at the same time as had the civilizations (C) that ?ourished at the same time those had (D) ?ourishing at the same time as those did (E) ?ourishing at the same time as those were
答案是A,但是我总觉得,如果用A,句末应该加一个did,和前面的flourished并列。 即, the site of an ancient civilization that ?ourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates did. 请问如果不加did的话,句子的结构该如何解释呢? |
