形容词倒装后在句首的用法

问题描述

True it is hard to make accurate predictions, but the steady growth of the information industry ensures that this line of products will be highly profitable.

请问，句子前半部分的粗体字是什么结构？谢谢老师们。

老师答疑

q老师：

我认为这句话省了一个逗号。True是副词，作状语。

查询语料库发现，True之后有逗号远比没有逗号常见：

True, it is not a clean fuel, and women face serious health problems from ingesting cooking smoke.

True, it is not very different from India, which took as its boundaries the ones established by the British Empire.

但是没有逗号的情况也不是完全不存在

True it is a perennial one, it generally can be relied upon to follow July, and precede September, but the Government hadn't allowed for it, or the fact that not much gets done that month.

True it is impossible to predict what will happen in the future, but being prepared and having goals in mind can still help if anything unexpected comes up.

曹老师：

true 是副词，作状语。不是形容词前置或倒装。

True状语it 形式主语is hard 系表结构to make accurate predictions不定式作真正主语。

译文：的确，要做出准确预测是很难的。
