15. At what speed was a train traveling on a trip when it had completed half of the total distance of the trip?
(1) The trip was 460 miles long and took 4 hours to complete.
(2) The train traveled at an average rate of 115 miles per hour on the trip.
这题的答案为E。请问B为什么不对呢?
偶想了想可能是句意理解问题,两种理解:
1. 这辆火车在整个行程中的平均数度是115m/h。(根据答案题目是这个意思)
2. 这辆火车以115m/h的匀速行使。(偶做题时的理解,根据答案是错的)那么想问第2种理解的英文表达方式应该是怎样的呢?谢谢作者: nbnhjf 时间: 2004-8-27 07:22
