---Can you guess the new Nike sports shoes?
---Yes. Maybe he asked his grandpa to pay for them, I think.
A．where he bought
B．how he paid for
C．when he paid for
D．why he bought
答案
答案：B
题目分析：根据Maybe he asked his grandpa to pay for them可知，本句应该是问怎样买的新耐克运动鞋，所以本题选B。
点评：本句实际是应该根据回答来选择相应的句型，如果单纯看宾语从句是很难选出正确选项的。
