NCE3-11 I saw the Off来自icer's face light up.不明这的 light up 为什么不用过去时，lighted up 或lit up
I felt sure I would never be able to close the case again. Suddenly, I saw the Officer's face light up. He had spotted a tiny bottle at the bottom of my case and he pounced on it with delight. 不明这的 light up 为什么不用过去时，lighted up 或lit up

这里就涉及到see的用法了
see+n.+do/doing 看见...做(正在做)....
+do (动词原形)，表自动作的开始到结束 see him cross the road
+doing的重点在于动作的进行状态
所以不用你说的过去式!!
