Although the airline has cut the number of cities ___ it flies to,each week several flights still make the round trip from CUBA to Jmaica. A.where B.when C.that D.what 答案是C,为什么不能选A
虽然where 可以起关系代词作用 表示范围 作介词宾语 但本题强调的是名称的点 所以用that 不过where可以作介词宾语 如 i hid behind the wall from where i could see him. 本句 如果用 from which ,which 只能代替 the wall 不能代替 behind the wall 而where指的 就是 behind the wall 其实 where 作介词宾语 司空见惯 如the city where you are from 不是the city which(that) you are from . where是介词from的宾语
