__________ that these creatures are linked to a common ancestor.
A．As is believedB．What is believed
C．That is believedD．It is believed
D

試題分析：考查句型：It is believed that…，據(jù)相信…,it 是形式主語，that引導(dǎo)的是真正的主語，句意：據(jù)相信這些生物和一個(gè)共同的祖先有聯(lián)系。選D。
點(diǎn)評(píng)：It is believed that…，據(jù)相信…這個(gè)句型可以改寫成：Sb/sth is said to do句型，要學(xué)會(huì)互相轉(zhuǎn)化，而且過去分詞除了believed，還有said，thought，suggested等。
