Semantic scope is the general term that is used to describe the semantic influence which negative forms or focusing adverbs, etc. exert on neighboring parts of a sentence (Quirk, et al, 1985). The phenomenon of scope is closely related to the ordering of clause elements, hence it deserves our attention. The position of a negative form, for instance, generally decides whatever follows it as nonassertive (e.g., any, anybody, anything, ever, etc), as shown:
Yīxiē lǎorén cóngbù máfan rènhé rén.
(Some old people never bother anybody.)
*Rènhé lǎorén cóngbù máfan yīxiē rén.
(*Any old people never bother some people.)
In such a sentence, the nonassertive form ‘rènhé rén’ (anybody), because it follows the negative word ‘cóngbù’ (never), lies within the scope of negation, whereas the assertive form ‘yīxiē rén’ (some people), which precedes the negative word does not. Therefore, it would be impossible to reverse the positions of the assertive and nonassertive words.
