plan

1.plan（名词）后面接for或of和动名词比接不定式普通，如a plan for（或of）developing the business和my plan for（或of）developing your business比a plan to develop the business和my plan (for you) to develop your business普通。

2.下面各句里习惯用复数形式plans，但并没有“多少计划”的意思：

• I have made plans to spend the holidays with you.
• He had intended to visit us, but the bad weather made him change his plans.
