主要介紹6個連詞，這6個連詞的共同特征是“所有的句子成分（主語，賓語，表語，介詞短語，副詞，謂語（句子），補語，同位語）都可以連接”，除了and會連接“補語，同位語”，其他的5個很少連接“補語，同位語”。6個連詞如下圖所示：
1 and
2 neither...nor...
連接主語：我和他都不想見你---neither i and he wants to see you.
連接賓語：他和他的朋友我都不喜歡---i like neither his friend nor him.
連接表語：他既不是老師也不是醫生---he is neither teacher nor docotor.
連接介短：他既不是出生在上海也不是北京---he was born neither in shanghai nor beijing === he was born in neither shanghai nor beijing
連接副詞：他既沒有死在樓上也沒有死在樓下---he died neither upstairs nor downstairs.
連接謂語：他既沒有給我打電話也沒有來---he neither called me nor came.
注：neither...nor是就近原則
3 both...and...
both...and...是兩者都怎樣怎樣，neither...nor是兩者都不怎么樣不怎么樣，所以both...and舉例與neither...nor相似，所以這里就不在贅述，只講兩者的一些細微差別，如下：
- 要是句子是否定的，用neither...nor與both...and都可以
- 要是句子是肯定的，只用both...and
只是按照上邊這樣講，可能會有點抽象，下邊舉例說明：
- 我和他都不想見你---neither i nor he wants to see you.=== both he and i do not want to see you.
- 我和他都想見你---both he and i want to see you.
注;both...and沒有就近原則，不會有第三人稱單數的情況
4 either...or...
either...or...表示“兩者選其一”。
連接主語：不是你錯了就是我錯了---either you or i am wrong.
連接賓語：你要么選這個要么選哪個---you select either this one or that one.
連接表語：他不是老師就是醫生---he is either teacher or doctor.
連接介短：他不是去北京就是去上海了---he went either to beijing or to shanghai.===he went to either beijing or shanghai.
連接副詞：我不是這個月就是上個月遇到他的---i met him either this month or last month.
連接謂語：你要么給我打電話，要么過來---you either call me or come.
注：either...or是就近原則。
5 not only ... but also ...
表示“不僅...而且...”
連接主語：不僅他，而且tom也去了北京---not only he but also tom went to beijing.
連接賓語：我不僅喜歡打籃球而且喜歡踢足球---i like playing not only basketball but also soccer.
連接表語：他不僅善良而且友好---he is not only kind but also friendly.
連接介短：他不光在學校學英語，在家也學---he learns english not only in shool but also at home.
連接副詞：他不光上個月沒來，這個月也沒來---he did not come not only last month but also this month.
連接謂語：他不但告訴了我真相，還幫了我---he not only told me the truth but also helped me.
注：not only ... but also是就近原則
6 as well as
表示“也”
as well as 與not only...but also造的例句差不多，只是強調的重點不一樣，下邊講解一下兩者的差別：
not only he but also tom went to beijing.（強調tom，即強調后邊的，所以謂語的形式與后邊的保持一致，也叫就近原則）
tom as well as he went to beijing.（強調tom，即強調前邊的，所以謂語的形式與前邊的保持一致，也叫就遠原則）
補充：
as well 是副詞，表示“也”，相當於too。
舉例：他去了北京，tom也去了北京---he went to beijing ,tom went to beijing as well.
