Ambiguity often arises due to（）, as is shown in the sentence " The fish is ready to eat."
A、polysemy
B、homonomy
C、grammatical structure
D、lexical structure
【正确答案】：C
【题目解析】：本题考查句子产生歧义的原因。语法结构也会导致歧义的产生。题干中的句子有两种理解：The fish is cooked or served，so ready for people to eat（鱼做好了或上桌了，可以吃了），或者The fish is ready to eat things(鱼准备好吃食物了）。这样就有歧义了。但是，假如说成 What a nice smell! The fish is ready to eat，那么，鱼—定是做好了，可以吃了。所以本题选C。
