现代汉语的“DJ-F的是+M”结构是“是”作为焦点标记的一种重要形式,标示句子中需要重点突出的信息,并根据具体语境产生对比和话题等附加功能。此外,这种形式的焦点标记同时还导致预设。
The "DJ + De(的) Shi(是) + M" structure is an important form of focus, outweighing some information from its context. Meanwhile, it extends extra functions of contrast and topic in particular contexts. Still, this form of focus also induces presupposition.
