有读者问如何做这道选择题：
(1)Don't worry. We'll have your son_________again.
A. to walk B. walks
C. walking D. can walk
B和D都不合语法，故不可选。A在语法上不算错，但“have+宾语+不定式（多不带to）”多表“请”、“叫”、“吩咐”，故不甚合题意。C是对的，因为“have+宾语+现在分词”结构常用以表示一种预期的目标或结果，再如：
(2)I'll have you speaking English in six months.
(3)In five minutes he had us all laughing .
这种结构还可用于下面两类的句子中：
(4)Don't shout! You'll have the neighbours complaining ! （表警告）
(5)I won't have you speaking like that about my sister. （表不允许）
