Answer the following questions.

Answer the following questions. Your answers should be clear and short.Explain what causes ambiguity in the sentence I like Mary better than Jean.
【正确答案】：

GRAMMATICAL STRUCTURE CAN LEAD TO AMBIGUITY. ON A GRAMMATICAL BASIS, THE SENTENCE HAS TWO DIFFERENT INTERPRETATIONS. IT MAY MEAN “I LIKE MARY BETTER THAN I LIKE JEAN” OR “I LIKE MARY BETTER THAN JEAN LIKES MARY”. 

【题目解析】：本题考查歧义产生的原因。语法结构也会引起歧义。这个句子可以看作是省略句引起的歧义。可以理解为：“我喜欢Mary胜过我喜欢Jean”或“我喜欢Mary胜过Jean喜欢Mary”。为了避免歧义，我们可以说：“I like Mary better than Jean does. 我比Jean更喜欢Mary”；“I like Mary better than I do Jean. 比起Jean我更喜欢Mary” ；“I like Mary better as Jean is untidy. 我更喜欢Mary，因为Jean不整洁”。
