To enjoy the scenery, Irene would rather spend long hours on the train _____ travel by air.

A.as

B.to

C.than

D.while

答案及解析： C

解析：

本题考查特殊句型的用法。句型would rather do…than do“宁愿做(前者)而不愿做(后者)”。故答案为C。would常和rather搭配在一起用来表达“宁愿”。英语中表示“宁愿做……，而不愿做……”。常用这几个句型：would rather do…than do; would do…rather than do…; prefer to do…rather than do…；

注意than后面是省略了to的动词不定式。平时学习要注意积累一些常用句型。
