一、语法一致原则1.主语是单数形式,谓语也用单数;主语是复数形式,谓语也要用复数。例1 All the scientific evidence____that increasing use of chemicals in farming____damaging our health.A.show;are B.shows;are C.show;is D.shows;is解析:选D。第一空主语是evidence,为不可数名词,所以谓语动词用单数;第二空主语是use而不是chemicals,所以谓语动词也用单数。2.both...and连接两个并列成分作主语时,谓语
First, the principle of grammatical consistency 1. The subject is a singular form, the predicate is also singular; the subject is a plural form, predicate also use plural.

The first empty subject is evidence, an uncountable noun, so the predicate verb is singular; the second empty subject is use instead of chemicals, so the predicate verb is also singular. 2.both ... and predicate when connecting two juxtaposed components
