并列連詞引導兩個并列的句子。 1) and 與or 判斷改錯： (錯) they sat down and talk about something. (對) they sat down and talked about something. (錯) they started to dance and sang.      (對) they started to dance and sing. (錯) i saw two men sitting behind and whisper (耳語)there. (對)i saw two men sitting behind and whispering there. 解析：   第一句： and 連接兩個并列的謂語，所以 talk 應改為 talked。   第二句：and 連接兩個并列的動詞不定式，第二個不定式往往省略to，因此sang 應改為 sing。   第三句：and 連接感官動詞saw 后面的用作賓補的兩個并列分詞結構，因此whisper應改為whispering。 注意：and 還可以和祈使句或名詞詞組連用表示條件。（or也有此用法）    make up your mind, and you’ll get the chance.  = if you make up your mind, you’ll get the chance.    one more effort(努力), and you’ll succeed.   = if you make one more effort, you’ll succeed. 2) both …and 兩者都 she plays (both) the piano and the guitar. 3) not only…but (also), as well as不但……而且     she plays not only the piano, but (also) the guitar. 注意： not only… but also 連接兩個分句時，一個分句因有否定詞not 而必須倒裝。     not only does he like reading stories, but also he can even write some. 4) neither…nor 意思為“既不……也不……”謂語動詞采用就近原則，與nor后的詞保持一致。     neither you nor he is to blame. 表示選擇的并列結構     1) or意思為“否則”。     i must work hard, or i’ll fail in the exam.     2) either…or意思為“或者……或者……”。注意謂語動詞采用就近原則。     either you or i am right.  表示轉折或對比     1) but表示轉折，while表示對比。     some people love cats, while others hate them.     典型例題     -- would you like to come to dinner tonight?-- i’d like to, ___ i’m too busy.     a. and                                b. so                           c. as                    d. but     答案d。but與前面形成轉折，符合語意。而表并列的and， 結果的so，原因的as都不符合句意。
