问题
单项选择题
The manager didn’t have time to go into his plan ______, but he gave us an idea about it.
A. in turn
B. in conclusion
C. at first
D. at length
答案
参考答案:D
解析: 本题是说经理没有时间去详细地探究他的计划,但他给了我们关于这个计划的想法。D项“at length长时间地;详细地;最终,终于”符合题意。如:He spoke at length on his plans for the future. We discussed the matter at length. At length he came to understand it. 其他三项中,in turn“依次地,轮流地,反过来”;in conclusion“最后”(用在结束语中);at first“最初,起先”,都与题意不符。
