Catherine ________ the letter before her mother came into her bedroom.
A.has written
B.was written
C.had written
D.is writing
答案C
剖析:此题主要考查动词的时态.依据后面的her mother came into her bedroom可知时间是过去,故可以排除A和D;B是被动语态,而此题为主动语态,故B也可以排除掉;由题意可知,Catherine是在妈妈进来之前写的,而妈妈进来的动作came into是一个过去的动作,故Catherine的动作为“过去的过去”,也就是说此题为过去完成时态,故答案为C.
