选择题
--I heard the high-speed train between Beijing and Tianjin ran_____ 350 kilometers a hour.
--That’s right. I’m looking forward to _____it one day.
A. at; take B. at; taking C. by; take
答案
答案：B
题目分析：句意：我听说北京到天津的高铁速度是350公里一小时。是对的，我期待有一天可以乘坐它。以…的速度，习惯用介词at, looking forward to 后接动名词，故选B
点评：英语中to为介词后接动名词的现象很多，中学阶段需要注意的还有pay attention to 注意；lead to导致；be used to doing sth习惯于做某事；stick to 坚持等，这些词之后都要用动名词形式，平时学习时要善于积累。
