I am glad that winter holiday is coming. I have set for itself a vacation plan.（我非常高兴即将来临的寒假。我为自己安排了假期计划。）
上面的句子对吗？假如对能不能把前面一句子修改为下面的句子？
I am glad about coming winter holiday.(介词短语）
I am glad about winter holiday to come.（不定式）
1. “寒假” 实质是个“假期”，是由多个holiday 构成的，应该用复数holidays。
N-PLURAL （学校的）假期
The holidays are the time when children do not have to go to school.
...the first day of the school holidays.
学校放假的第一天
2， 要么用vacation（假期）。
3. “为我一个人拟定了假期计划”，应该说：make a holiday/vacation plan for myself。
翻译如下：
I am glad that the winter holidays are coming. 或：
I am glad about the coming winter vacation/holidays.
I have madea holiday/vacation plan for myself。
