題目

them up and move them forward. Theyzoom along the tracks at incredible speeds, far exceeding those of traditional trains. They can achieve speeds above 300miles per hour, A. pushed B. pushes C. that push D. that are pushed42

官方答案

• 答案：C. that push

解析

空格後接「them up and move them forward」，可見前面是複數先行詞（如 magnets）引出的關係子句；關係代名詞 that 代替複數先行詞時，動詞須用原形 push，且與並列的 move 同為主動、同形。A pushed 為過去式或被動，B pushes 為單數現在式，D that are pushed 為被動語態，語意會變成「被推上去」，與後面主動的 move them forward 不對稱。故選 C。
