中學(xué)英語連詞的用法
1.并列連詞
both…and “既…又…”,謂語用復(fù)數(shù)動(dòng)詞
neither…nor “既不…也不…”,含否定意義,遵循就近原則,謂語動(dòng)詞由靠近它的那個(gè)主語來決定單復(fù)數(shù)。
either…or… “或者 …或者…”、“不是…就是…”
and“和”, 連接兩個(gè)并列成分,連接謂語時(shí)兩個(gè)動(dòng)詞時(shí)態(tài)應(yīng)一致。
but “但是”, 表轉(zhuǎn)折,不能與 though1 同時(shí)出現(xiàn)在句中。
or “或者”,在否定句中,并列成分的列舉常用or,而不用and。
例: I have brothers and sisters.(否)
I don't have brothers or sisters.
= I have no brothers and no sisters.
