有一读者问：有这样一道题：
(1)The manager was thinking_________on business the next day.
A. to go out B. out to go
C. of going out D. on going out.
答案为什么是A?为什么不是C?
这里不选C，可能是由于 be thinking of 具有尚未做出最后决定的含义。这里选A，是因为 think to 强调意图(intend)或企图去办一件比较具体的事，如《红楼梦》英译本中有一句是这样的：
(2)One morning, he had just washed and dressed and was thinking to ask his grandmother's permission to pay another visit to his friend （Chin Chung）, ...
再如：
(3)He thinks to deceive us.
(4)They think to influence the voters.
think to 有时意为期待(expect),例如：
(5)I never thought to see you here.
在口语里， think to 还可表“记得”或“想到”，相当于 remember, 如：
(6)I didn't think to lock the door.
(7)I didn't think to ask.
