Question

请大家帮我分析一个选择题，谢谢了

I don’t know if twenty-four hours a day is enough for you.Many people are busy with work and they keep on working until midnight.Here are possible reasons for this.
One of the reason may be the heavy workload(工作量)，and another one is probably cause by bad _____.They are not in the habit of writing down the work they are going to do.
A.planning
B.plan
C.thinking
D.thinks
参考答案是A，为什么不是B呢

Answer 1

B是名词呀，要有冠词的，a bad plan 或者bad plans
选A则是把plan用作动词，bad是修饰动词的，介词后面要加动词ing哦，即 by planning
希望采纳哦~~谢谢~~

Answer 2

plan
1英语释义 a series of steps to be carried out or goals to be accomplished
they drew up a six-step plan they discussed plans for a new bond issue
2. an arrangement scheme
a plan for seating guests
planning
1.英语释义n.
1. an act of formulating a program for a definite course of action
the planning was more fun than the trip itself
2. the act or process of drawing up plans or layouts for some project or enterprise
3. the cognitive process of thinking about what you will do in the event of something happening
his planning for retirement was hindered by several uncertainties
由此可以看出，plan做名词讲的时候，多为计划，方案，平面图，设计等
而planning则更侧重于计划的实现，策划，如poor planning 计划不周
希望可以帮到你

Answer 4

B 复合名词，bad plan

Answer 5

bad是形容词，后应该加一个名词，planning是名词，译为“计划”，故选A,
