1、appointed是过去分词，被动，应当修饰人，意思是：某人在1950年被HST委任了一个职位，于是...
2、看句子的重心，应当是后半句
3、可以翻语法笔记

AE長得比較像，先看這兩個選項
Ｅ選項明顯頭重腳輕，Ａ的結構優於Ｅ

接著剩下選項開頭都不太一樣，所以從後面看
發現ＢＤ一組，ＡＣ一組
先看ＢＤ：
Ｂ--> in ES?? ES是一個人，前面加 in明顯錯誤
Ｄ-->第一個african woman會指代到 HS，但是還不確定是否正確，先保留

接著看ＡＣ
Ａ：ＥＳ可以做appoint的主語，檢查後也沒什麼大問題，保留
Ｃ：in 1950擺放位置錯，刪除

最後剩下ＡＤ
比對句意後
很明顯知道the first african women是 ＥＳ 不是ＨＳ
所以最後答案選Ａ
