问题
选择题
------Have you known each other for long?
------ Not very, ________we started to work in the ABC Motor Company.
A.before
B.since
C.when
D.after
答案
答案:B
题目分析:考查介词,before 意思“在…之前”,since意思“自从”,when意思“当什么时候”,after意思“在…之后”,句子意思“自从我们开始在美国汽车公司”,所以选B
点评:介词是个难点,固定句型start to do sth意思“开始做某事”; 专有名词the ABC Motor Company意思“美国汽车公司”
