??and一詞在英語里使用頻率極高。它幾乎可以連接任何語法作用相同的詞語或句子，表示一種"追加"的關(guān)系。當(dāng)and連接兩個單個名詞作主語時，一般情況下，句子的主語就是復(fù)數(shù)概念，其謂語動詞要遵循語法一致原則，用復(fù)數(shù)形式。但是，在某些情況下，由于and連接的并列主語因其結(jié)構(gòu)及含義不同，要求謂語動詞的數(shù)也不同，須遵循意義一致的原則來判別。
??1?如果and連接的是兩個單數(shù)可數(shù)名詞并且兩個名詞前均有冠詞，就意味著這是兩個人或物，謂語動詞要用復(fù)數(shù)。例如：
Behind the wall standa house and a garage．在大墻的后面有一座房子和一個車庫。
The director and the secretary were present at the meeting．總監(jiān)和秘書都出席了會議。
??2．如果and連接的兩個可數(shù)單數(shù)名詞，前一個有冠詞，后一個沒有冠詞，一般來說，這意味著是一個人或事物，謂語動詞要用單數(shù)。例如：
??A painter and decorator was painting the walls of the house．一位油漆工兼裝璜工正在粉刷房子的墻壁。
??The editor and publisher of the magazine is a friend of my father．那家雜志的編輯兼出版商是我父親的朋友。
??3?如果and連接的兩個名詞是不可數(shù)名詞，而且前面都沒有冠詞，若兩個詞連用表示一個事物或一個概念，謂語動詞要用單數(shù)；如果兩個詞表示的是兩個事物或兩個概念，謂語動詞要用復(fù)數(shù)。例如：
Courage and resolution?are?the spirit and soul of virtue．勇氣和決心是品德的精神和靈魂。
??Trial and erroristhe source of knowledge．反復(fù)嘗試，不斷摸索，是知識的源泉。
??This bread and butter?is?too thick．這塊涂了黃油的面包太厚了。
??4．當(dāng)and連接的兩個名詞前都有each， every，many a，no等單數(shù)概念的限定詞修飾時（第二個名詞前的修飾語有時可以省略），謂語動詞要用單數(shù)。例如：
??Every hour and every minute?is?precious to?us．對我們來說，每一個小時，每一分鐘都是珍貴的。
??Many a boy and many a girlhasread that novel．許多男孩和女孩都讀過那本小說。
??During the Christmas season，every train and airliner?was?crowded．在圣誕節(jié)期間，每列火車，每班飛機都載滿旅客。
