【答案解析】[听力原文] 13-16 W: There are many interesting stories about how a baby learns to say its first word. Now, Mark, would you like to share your story with us? M: OK, here is my story. I was about 18 months old, I think. And I had just started saying my first word. Every time a truck went by, I shouted a word that sounded like "truck", but to everyone else it sounded nothing like it. My parents tried to correct me, but failed. Then about 3 months later, we traveled to New York. As we were waiting for our plane at the airport, I looked out of a huge window. At that very moment, I saw the largest truck in the world. I had to tell someone about this. I turned to my father, who was standing next to about a thousand people waiting for flight, and screamed "Truck! Truck!" My father tried hard to shut me up, but I was so excited and I kept screaming my special word. My poor mother decided that she didn't know this baby and ran to the lady's room where she hid until I finally stopped. Well, I was talking like a normal child. However, my parents will never forget the very first word I produced in my life. 细节题。男士在叙述自己故事时指出：Every time a truck went by, I shouted a word that sounded like "truck"(每当有卡车经过时，我都会喊出一个听上去像是“卡车”的词)，即男士小时候学会说的第一个词就是“卡车”。
单选题
How old was the baby when he learned to say that word correctly?
【正确答案】
B
【答案解析】[解析] 本题较难，需要考生在注意听清细节的同时进行一定的推断。虽然男士说自己在18个月大时就会说“卡车”，但此时只能说听起来像“卡车”，别人听上去却不像(but to everyone else it sounded nothing like it)，故显然不合题目要求的correctly(正确地)。而男士接着说3个月后他们去纽约，正是在这次在机场他喊出了“卡车”这个单词，因此本题答案就应选[B_。
单选题
What did the father do when the baby screamed that word at the airport?
【正确答案】
B
【答案解析】[解析] 细节题。男士叙述到自己在机场不停地喊“卡车”时指出：My father tried hard to shut me up(我父亲试图让我住口)，故本题答案是[B]。[A]项是此前的做法，[C]项则是他母亲的做法。
单选题
Why did the mother pretend not to know the baby?
【正确答案】
C
【答案解析】[解析] 本题属于推断题。男士叙述在机场发生的故事时，对他母亲只提到了一句：My poor mother decided that... until I finally stopped(我那可怜的母亲只得装作不认识这个宝宝，跑到女洗手间藏了起来，直到最后我不再叫嚷)。由此并结合常识即可知，本题答案为[C]，即他母亲是因为对他束手无策才那样的。
