小伙伴们能不能帮忙看看这个SC题怎么做，尤其D项怎么错的，答案看不懂

27. In the seventh century B.C., the Roman alphabet was adapted from the Etruscan alphabet, which in turn had been adapted in the previous century from a western

Greek alphabet, which itself had been adapted earlier in the same century from the

Phoenician alphabet.

(A) which itself had been adapted earlier

(B) adapting itself earlier

(C) itself being adapted earlier

(D) having been earlier adapted itself

(E) earlier itself having been adapted

我是这样做出来的：
A 扫了一眼，没啥错，先留着吧。
B adapting itself...首先，alphabet能adapt自己吗？感觉不可能。另外，逗号+v-ing有两个作用：1.表前面动作发生的结果 2. 表对前面东西的补充说明，但时态要和前面一致，不能另起一个。这里显然不能做结果，如果做补充说明，时态不是同时的，应该是在之前。所以排除B
C 这是独立主格用法，首先反身代词不能单独作主语，另外为了表示时间顺序，有个having been什么的是必要的。
D 逗号+V-ing，理由同B，时态不对，不能这么用。
E 一看earlier的位置变了，放在最前面了，但这样做明显不对。因为earlier应该修饰in the same century.
最终选A
