问题
选择题
---- ________ it is late, I shall go home now.
---- OK, go ________.
A.So; down
B.If; up
C.Since; ahead
D.Because; out
答案
答案:C
题目分析: 句意:因为晚了,我现在要回家了,好的,请先行。So因为down 向下 If;如果up向上
Since既然ahead 提前 Because;因为out出去,根据t is late, I shall go home now.,可知是告别用语,go ahead先行一步,go down下去,go up 上升,go out 出去,根据语境选C。
