主謂一致，指人稱和數(shù)方面的一致關(guān)系。分為:語法一致, 內(nèi)容一致, 就近一致。
(一) 語法一致原則: 即主語為單數(shù),謂語用單數(shù),主語為復(fù)數(shù),謂語也用復(fù)數(shù)。
1. 單數(shù)主語即使后面帶有with , along with, together with, like(象), but (除了),except,besides, as well as, no less than, rather than(而不是),including, in addition to 引導(dǎo)的短語, 謂語動詞仍用單數(shù)。如:Air as well as water is matter. 空氣和水都是物質(zhì)。Noone except two servants was late for the dinner. 除了兩個仆人外, 沒有一個人遲來用餐。

6. 若主語中有more than one 或many a/an , 盡管從意義上看是復(fù)數(shù),但它的謂語動詞仍用單數(shù)。但more+復(fù)數(shù)名詞+thanone做主語時, 謂語動詞仍用復(fù)數(shù). 如:
