求指点一个true的用法
There remains today a stubborn,widespread fantasy that libraries will buy enough copies of a book to pay for the cost of producing it.【True】,once upon a time,a university press could expect to sell about 1,500 copies of a typical monograph,with 800 to 1,000 of those sales to academic libraries.
请问此外的true是不是it is true that的省略形式?
答
我觉得true在这里是副词,相当于exactly,作状语.
比较一下这两个不同的用法：
1.Humble and true,he never lies.
这句里的true是形容词,前面省略了being：
Being humble and true,he never lies.
2.True,he always goes home after work.
这句不能改成being true,意思完全不一样了.虽然改成it is true that意思会一样,但是语法结构不一样,所以不是it is true that的省略形式.
