四選一
The planning session was highly ____, resulting in a clear schedule for the project.
看答案
productive
was 後需要形容詞描述會議，且 highly 修飾該形容詞，因此選 productive。productivity 是名詞，不能搭配 highly 形成此處的補語；productively 是副詞，不能直接描述主詞；produce 作動詞或名詞都不符合此句結構。
同義改寫
The factory became more productive after the equipment upgrade. → The factory could produce larger quantities after the equipment upgrade.
此處 more productive 表示生產能力提高，改寫為能生產更大量的產品，未額外宣稱獲利增加。
Our discussion about the delivery schedule was productive. → Our discussion about the delivery schedule yielded useful results.
此處 productive 表示討論有成效，與 yielded useful results 所表達的產生有用成果相符。
