alone

音標(biāo)發(fā)音

alone的基本含義在于陳述獨(dú)自一個(gè)人而沒有同伴或助手的客觀事實(shí),引申可用于物。在與leave或let連用構(gòu)成的習(xí)語中, alone的意思是“任其自然”。
alone在句中主要用作表語,其后常接介詞in引起的短語。偶爾可用作定語或賓語補(bǔ)足語,用作定語時(shí)多須后置,偶爾也可前置。
不可說very alone,而應(yīng)說much alone或very much alone,用very much比用much更為普遍。
alone用作形容詞時(shí)不用于比較等級(jí)。
let alone可用作連詞,其后可接任何詞性的詞項(xiàng),用于非正式語體,且多用于否定句。

alone用作副詞的基本含義是指無伴或沒有別人幫助而獨(dú)自干某事。
alone用作副詞時(shí)不用于比較等級(jí)。
alone，lone，lonely和lonesome的比較：alone是表語形容詞，因此能說The man is alone，不能說an alone man。也不能說very alone，只能說much alone或very much alone，且后者比前者普遍。lone是定語形容詞，因此能說a lone man,不能說The man is lone。alone指“獨(dú)自的”，lonely指“寂寞的”，一個(gè)人也許alone但并不lonely（雖自己一人，但不寂寞），或是雖不alone而感覺lonely（雖不是自己一個(gè)人，卻還是寂寞）。有時(shí)lonely還指“不大有人到的”，如a lonely house。lonesome同lonely意思相近，指“孤單的”。Mary is very lonesome with her husband and children so much away.
She alone went指“只有她去”，She went alone指“她獨(dú)自去”。而leave him alone有時(shí)指“聽任他獨(dú)自一個(gè)人”，有時(shí)指“不干涉他”，let him alone指“不干涉他”；
