I wish to thank Professor Smith withouthelp I would never have got this far.(·天津 7)A.

问题补充：

I wish to thank Professor Smith，withouthelp I would never have got this far.

(·天津，7)

A. who

B. whose

C. whom

D. which

答案：

A. who

B. whose

C. whom

D. which

解析：B

解析句意为：我想要感谢史密斯教授，没有他的帮助我就不会走得这么远。whose是关系代词，引导定语从句，表示“……的”。考生容易误选C项，因为只看到了without whom语意上相当于without Professor Smith，而忽略了题干中的help。若选C项的话，可去掉题干中的help。
