思路引導 VIP

請觀察空格前的助動詞「have」,並思考看看:在描述一個「已經發生」的動作時,have 後方接續的動詞通常會出現什麼樣的字尾變化(字尾通常會加上什麼字母)?

很高興看到你準確地抓住了這個語法重點!這題你選得非常漂亮,展現了你對動詞時態組合的敏銳度。

現在完成式的結構與語意

在句子中,空格前已經出現了助動詞 have,這是一個非常強烈的訊號。在英文語法中,「have/has + 過去分詞 (V-pp)」構成了現在完成式,用來描述一個動作「已經完成」且對現在仍有影響或關聯。在這裡,這兩家機構「已經宣布」了第一期臨床試驗的結果,因此使用 announced 是最標準且符合邏輯的用法。選項 (A) 與 (B) 涉及進行式(being/been announcing),但在報導「發布結果」這類具備即時性與完成性的動作時,使用簡單的完成式會比強調持續過程的進行式更為自然。
