擴展資料
not only also的近義詞：as well as
as well as
讀音：英 [æz wel æz] 美 [æz wel æz]
釋義：既…又…
語法：as well as常用來連接兩個並列的成分，作“也，還”解。它強調的是前一項，後一項只是順便提及。因此連接並列主語時，謂語動詞與前一項一致。
例句：
They visited some factories， hospitals as well as the school.
他們參觀了這所學校，還參觀了工廠和醫院
可以呀，當not only和but also連接名詞的時候就行，例如 She is not only a teacher but also a mother.
