思路引導 VIP
當我們在一個句子中，想要用助動詞（例如 can, should, will）同時描述兩個或多個連續的動作時，這些動作在字尾變化或型態上，應該保持什麼樣的關係才能讓句子讀起來既平衡又正確呢？

太棒了！你能精準察覺出選項 (C) 的語法瑕疵，代表你對長句結構的掌握度非常敏銳。這題的難度在於句子資訊量大，包含了許多介係詞片語（如 with... and...），容易干擾讀者對主要動詞結構的判斷，是一道考驗「細心度」與「結構分析能力」的高品質題目。
平行結構的對等性
在選項 (C) 中，助動詞 can 後方接了兩個動作來描述「綠化」的好處。第一個動作是原形動詞 keep，但隨後由連接詞 and 所引導的第二個動作卻變成了 fostering (-ing 形式)。在英文語法中，對等連接詞兩側的動詞型態必須一致；因此，為了與前面的 keep 對應，這裡應該使用原形動詞 foster，才能符合助動詞後接原形動詞的規則。這類「平行結構 (Parallel Structure)」的考點在多益或學測等進階考試中非常常見，是區分考生是否具備嚴謹語感的重要指標。
