The city is believed      over by sandstorms from AD200 to AD400.
A．to coverB．to be covered
C．to have been coveredD．that was covered
C

試題分析：The city與cover之間是被動(dòng)關(guān)系，故用不定時(shí)的被動(dòng)式；cover這個(gè)動(dòng)作發(fā)生在believe之前，故用不定式的被動(dòng)式的完成時(shí)，故選C。
點(diǎn)評(píng)：不定式的完成時(shí)表示的動(dòng)作發(fā)生在謂語動(dòng)詞表示的動(dòng)作之前，強(qiáng)調(diào)動(dòng)作的先后順序。
