请帮我讲解一下这个英语句子：Anything less than a B from me and I'm in trouble.
上文是：My parents expect me to do well in school,even though my brothers are pretty bad students.
请详细讲述一下该句型的用法,
答
这不是一个很正式的句子,有一些口语化.
Anything less than a B from me and I'm in trouble.
意思是,任何（测试）只要我得到B以下的成绩,那我就有麻烦了.
and表示一种隐含的条件关系.
不用纠结于语法,这不是很严格的书面语.
