中文摘要：

具有三个或多个次第比较项的＂更＂字句,都是包含多次两项比较的复句。由于比较基点不同,可以构成顺向递较、逆向递较和交互递较三种格式。含有分较和同较的多项比较句并不是真正的多项次第比较式。多项次第比较式包含兼较、合较以及属种、模糊等多种比较格式。多项次第比较否定句在比较方式、标记、预设等方面具有相应特点,但在比较项数、基点、程序等方面都与肯定比较句一致,也是多次两项比较格式。

英文摘要：

The sentence using ɡènɡ has three or more sequential comparative items,which involve multiple comparisons of two items. Because of differences of basic comparative points,three comparative patterns can be identified：the successive progressive comparison,the reverse progressive comparison and the interactive progressive comparison. Sentences of multiple comparisons including respective comparison and simultaneous comparison are not real multiple comparisons. Multiple comparisons include various patterns such as concurrent comparison, combining comparison, generic-specific comparison, fuzzy comparison, etc. The negative forms of multiple sequential comparative sentences have characteristics in terms of contents, markers, presupposi- tions, etc. , but they are basically consistent with their affirmative counterparts in such aspects as comparative items, basic points and patters and are all multiple comparisons of two items.
