题目
题型:不详难度:来源:
Have you finished you work  ? Yes, I have finished it  . I finished it    1 hour ago.
A.already ,yet ,/B.yet , already, /
C.yet ,yet, sinceD.yet ,already, since

答案
B
解析

试题分析:already多用于肯定句,表示一事实 意为 已经 早已;yet则多用于否定句、疑问句,意为 还、尚、迄今、到那时。Since表示自从……以来。句意:你已经完成你的作业了吗?——是的,我已经完成了。我是一个小时前完成的。1 hour后已有副词ago,故不再用介词since,故选B。
点评:英语单词的一个特点就是一词多义,一词多性,即一个单词可以有多个不同词性的用法。因此我们首先要详细了解这些单词作为不同词性的含义及用法,尤其注意其比较特殊的用法,然后结合语境选择正确答案。
