As I was putting the bike together,I discovered a piece was missing.
时态的运用.前半句用过去进行时我理解,但是后半句为什么不是 a piece missed呢?后半句应该用一般现在时呀.
如：As she was working on the computer,she lost her internet connection.

As I was putting the bike together, I discovered a piece was missing.因为missing是以-ing结尾的形容词,在此用作表语.这里前后句都是过去时(过去进行时也属过去时的一种).

i discovered a piece was missing.有没有和missing相近的形容词呢?
