【英文】lit up 是什麼意思???

你這一個題目 中間有一句是錯誤的.

> Besides, the dogs' reward center, _______ becomes active when something pleasant happens, lit up when they heard words of praise with praiseful intonation.

1. lit 是常常用在 light (verb)的過去式.所以 lit up = lighted up = 發亮(主動) or 被點亮(被動) 的意思.

2. 這句錯誤的地方在於 前半句 "becomes active when ... happens"(現在簡單式) 與後半句 "lit up when ... heard..."(過去簡單式)的不一致. 而我並不是說 醬子變化是不被允許的.只是在醬子的"科學論文"中 是不洽當的.

在科學論文中,一般而言,對實驗的觀察要用 過去式 或是 完成式.而推論/結論 要用現在/未來式.

醬子的混用 實在很 令人糊塗.反而是你在這一個試題 中應該學到的.
