问答题
Why did the author's heart pound when he clutched his dime?
【正确答案】正确答案：He could go across the street and bought Coke independently.
【答案解析】解析：第11段描述了作者兴奋的心情，上文提到作者本以为祖父当然会和他一块过马路，结果祖父让他自己一个人穿过马路，这是他兴奋的第一个原因；第14段提到第二个原因，首句提到当他走进车库时心跳加快，段末指出这是因为他曾多次幻想能亲自购买可乐，可见答案为He could go across the street and bought Coke independently。
问答题
What did "this dream" in Para. 16 mean?
【正确答案】正确答案：Drinking a whole bottle of Coke.
【答案解析】解析：第16段第4句说作者紧紧抱着可乐瓶，生怕祖父要他把可乐倒在杯子里。第7段也提过作者以前只是喝过几口可乐，但从未喝过一整瓶的可乐(certainly never my own bottle)。由此可见，这个小小的梦想指的就是一个人喝一整瓶的可乐，故答案可以表述为Drinking a whole bottle of Coke。
