talk about cheap的用法对吗

问题描述

有这样一个句子：
Talk about cheap. I bought a lot and gave some to my neighbours.
请问句子中的 talk about cheap 用得对吗？感觉不像是一个完整的句子（即cheap后面应该有个名词之类的吧）。

老师答疑

蒋老师：

▲其实 talk about cheap 是习语，用于强调 cheap，意思是 It’s very cheap。即原句意思是：

Talk about cheap. I bought a lot and gave some to my neighbours. 真是便宜。我买了很多，并分了一些给我的邻居。

▲关于该习语，《朗文当代英语词典》在 talk 词条有解释如下：

talk about lazy / cheap / hungry etc: spoken used to emphasize that someone or something is very lazy, cheap, hungry etc 真是懒惰 / 便宜 / 饿 等

该词典给出了一个例句，是关于 lazy 的：

Talk about lucky. That's the second time he's won this week! 真是运气好，这已经是他本周第二次赢了！

刘老师：

cheap 偶尔也用作名词，意为“廉价货”。

talk about 意为“说起，谈起”。

Talk about cheap. 意为“说起便宜货来”，典型的口语化英语。

I got this cheap at a department store sale.  我在百货公司特价廉售时买到了这件便宜货。
He is always trying to get things on the cheap.  他总是想贪便宜。
