题目
题型:不详难度:来源:
By the time my mother came back from work, my sister and I ________ supper and were waiting for her at the table.
A.have cooked B.were cookingC.had cookedD.would cook

答案
C
解析

试题分析:考查时态。By表示“到…时为止”,要与完成时连用。本题by后面的时间是一个过去时的时间,故使用过去完成时的时态。句意:到妈妈下班回家的时候,我的姐姐和我已经做好了晚饭在等她吃饭了。说明我们做好晚饭是在妈妈下班之前。故C正确。
点评:连词by到…时为止;该词经常与完成时连用,如果后面是现在的时间,句中就使用现在完成时;如果后面是过去的时间,就使用过去完成时;如果后面是将来的时间,就使用将来完成时。
