单选题
Sam wanted to kill Tod because______. [A] they often fought(打架) each other [B] Tod had a too good appetite (胃口) [C] Tod was not useful
【正确答案】
B
【答案解析】[精解] 文中第一段就说"It was very helpful，but it ate too much．So he didn't like it He wanted to kill Tod．”。Tod虽然很有用，但是它吃的太多所以Sam不喜欢它，想把它杀掉。A的意思是他们经常打架，不符合文意。C的意思是说Tod没有用，也与文意相背。B的意思是Tod的胃口太好，也就是吃得太多，与原文相符。因此正确答案为B。
