語法是學(xué)習(xí)的重點(diǎn),以后同學(xué)們在學(xué)習(xí)語法的時(shí)候,一定會遇到關(guān)于“do but do”的問題,所謂“do but do”原則是指,并列連詞兩邊的成分包括性質(zhì)、屬性和結(jié)構(gòu)一定是相同的,例如句子只能與句子并列,名詞只能與名詞并列,形容詞只能與形容詞并列,非謂語動詞只能與非謂語動詞并列等。下面我們就來學(xué)習(xí)一下這個原則。
Virtue dwells not in the tongue but in the heart.看人看心不看嘴。
5)從句與從句并列:
I know that he has been arrested and that he is in prison.我知道他已經(jīng)被捕并且進(jìn)了監(jiān)獄。
6)句子與句子并列:
She looks very young, but she is already in her 30’s.她看上去很年輕,可是她已三十多歲了。
It never rains but it pours.禍不單行。
【補(bǔ)充】并列連詞and, but, as well as, or, or else, both…and, neither…nor, either…or, not only…but(also), rather than, as…as等以及從屬連詞than可連接兩個對等的詞和對等的結(jié)構(gòu)。
1)所連接的謂語形式必須一致
【例句】He went shopping, bought some gifts and visited his old friend.
2)所連接的詞或短語形式必須一致
【例句】Your success is based not only on what achievement you make, but also on what you are.
3)連接的非謂語動詞的形式必須一致
【例句】People find eating vegetables more healthy than fasting.
4)所連接的句子結(jié)構(gòu)必須一致
【例句】My girlfriend is pleased with what I have said and all that I have done.
在英語表達(dá)中,有一個不成文的原則,叫作避免重復(fù)原則。比方說在并列句中,并列連詞左右兩邊的部分,在內(nèi)容上有重復(fù)的,一般后面的部分要省略掉重復(fù)的內(nèi)容。但是兩邊部分的內(nèi)容結(jié)構(gòu)一定是對稱的和平衡的。今天講的“do but do”原則就是并列句中的一種典型句式,希望對大家有幫助。
