The teachers were discussing the reaserch project that they would like to see ____ in the coming holiday.
A complete Bcompleted Ccompleting D to complete
B.see sth done.project和complete是被动关系,所以用过去分词表被动.
-I hear Jane has gone to the BEIJING for her holiday
-Oh how nice !Do you konw when she ____?
Awas leaving B had left C has left D left
D.由问句has gone得出这人去还没回来,所以问她什么时候去的用一般过去式就行了.
