6. Would you call me as soon as you find out 你一弄清楚了就給我打電話好嗎 as well as用法作為習(xí)語用作介詞時，as well as的涵義是“還有”、“不但…而且…”。值得注意的是，在A as well as B的結(jié)構(gòu)里，語意的重點(diǎn)在 A，不在 B。因此，“He can speak Spanish as well as English.”的譯文應(yīng)該是：“他不但會說英語，而且會講西班牙語”，決不能譯作：“他不但會說西班牙語，而且會講英語”。如果這樣翻譯，就是本末倒置了。as well as和 not only… but also…同義，但前者的語意重點(diǎn)和后者的語意重點(diǎn)恰好顛倒。如果 as well as用作連詞引出比較從句，其義為“和…一樣好”。因此，“He speaks Spanish as well as English.”應(yīng)譯作：“他說西班牙語像說英語一樣好”。語意的重點(diǎn)依舊在前部，不在后半部。請注意 as well as以下的用法：She called on you as well as I.不但我來看你，她也拜訪了你。She called on you as well as me.她不但拜訪了我，也拜訪了你。在下列句中，as well as表示“像…一樣”的涵義：She as well as you is an English teacher.她像你一樣也是英文教師。這里的謂語動詞用is，不用are，因?yàn)榫渲械闹髡Z是she，不是she和you。As well是副詞短語，其義為“也”，相當(dāng)于too，它一般放在句末，有時和連詞and或but搭配使用。例：He is a worker，and a poet as well.他是工人，但也是詩人。China possesses enormous quantities of coal and is rich in other minerals as well.中國擁有大量煤炭，其他的礦藏也很豐富。Mr.Liu can speak English，but he can speak Cantonese as well.劉先生會說英語，但他也能講廣東話。as well as 可連接并列的單詞或短語如果as well as 前面是動詞不定式，那么其后的動詞也是不定式，但to要省略應(yīng)保持一致。由as well as 連接的復(fù)合主語并不影響謂語動詞的數(shù)as well as 連接的人稱代詞既可以是主格也可以是賓格，但句意不同。as well as 用于肯定結(jié)構(gòu)和否定結(jié)構(gòu)中，其意義不同強(qiáng)調(diào)連續(xù)性和反復(fù)性，and連接相同的兩個詞，可以是動詞、名詞、形容詞或副詞祈使句+and+簡單句”結(jié)構(gòu)，表示條件關(guān)系，祈使句相當(dāng)于if引導(dǎo)的條件從句。在口語中，and可用在come, go run, hurry up, stay, stop等動詞后代替表示目的的動詞不定式，這些詞也可以接帶to的不定式and位于句首時常用來承上啟下，有“那么;于是;因此”之意and用來連接數(shù)詞(=plus)時，表示“加”。and all that = and so on = and so forth = and what not，意為“諸如此類;等等”。and yet表示“但是;然而”。as well as連接兩個動詞時，有三種情況：1)前后兩個動詞的時態(tài)要一致。即：若第一個動詞是一般現(xiàn)在時，第二個動詞也應(yīng)是一般現(xiàn)在時;若第一個動詞是一般過去時，第二個動詞也應(yīng)是一般過去時。例如：He publishes(published)as well as prints(printed)his own books.他的書是自己印刷并出版的。2)如果第一個動詞是復(fù)合時態(tài)，或由can，may， must等加動詞構(gòu)成時，as well as后面可省去助動詞或情態(tài)動詞，此時，as well as意為“既……又……”。例如：We are repairing the roof as well as painting the walls.我們在粉刷墻壁，同時也在修理屋頂。She can /could sing as well as dance.她既會跳舞也會唱歌。3)如果第一個動詞是不定式，as well as后面的動詞也要用不定式，但要去掉to。例如：You can't expect her to do the housework as well as look after the children.你不可能叫她既照管孩子又做家務(wù)。5.注意as well as的另外兩層涵義：1)as well as還有“除……之外”之意。例如：As well as knowing some Russian，she speaks English very well.除了懂得一點(diǎn)俄語之外，她的英語講得很好。2)as well as還可視為as...as結(jié)構(gòu)，用于副詞的同等比較?？山庾鳌昂汀粯雍谩薄＠纾篐e can speak English as well as you can.
