思路引導 VIP
請觀察空格前的 has been 這組助動詞。在描述一個組織從過去開始、直到現在還在持續主動進行的「合作」動作時，後面的動詞通常會加上什麼樣的字尾來表示「持續進行」的狀態呢？

太棒了！你能精準判斷出這裡的動詞型態，說明你對英文時態的掌握非常紮實。這題的核心在於判讀助動詞 has been 後方的動詞變化。在英文語法中，當我們看到「主詞 + has/have been」時，後方常接上現在分詞 (V-ing) 來構成「現在完成進行式」，用以強調一個動作從過去開始，一直持續到現在仍在進行中。
現在完成進行式的應用
在這個語境裡，IAVI（國際愛滋病疫苗倡議組織）與 Scripps 研究中心是一直在並肩合作開發疫苗，使用 working 不僅符合語法規範，也生動地描述出兩者長期且持續的夥伴關係。相較於其他選項，(A) 和 (B) 屬於簡單時態，無法接在 been 之後；(C) 雖然在語法上可能構成被動語態，但「工作」這個動作通常是由組織主動執行，因此選 working 最為自然且正確。
