大學(xué)英語六級(jí)語法常考知識(shí)
在學(xué)習(xí)英語六級(jí)的過程中,我們常遇到only與其它詞或結(jié)構(gòu)搭配來表達(dá)不同的意思,現(xiàn)將這些用法示例分享給大家,大家可以作為參考。
一、only引導(dǎo)的'詞組或句子放在句首作狀語時(shí),通常要用倒裝結(jié)構(gòu)。
如 Only in this way can you solve the problem. 只有通過這種方式你才能解決問題。
Only if you study hard can you pass the exam. 只有努力學(xué)習(xí)才能通過考試。
Only then did I realize my mistake. 只有那時(shí)我才意識(shí)到錯(cuò)了。
二、not only...(but also)出現(xiàn)在句首時(shí),如果架連接的是兩個(gè)句子,常用倒裝。
如 Not only did we lose all our money,but we also came close to losing our lives. 我們不僅丟了錢,還差點(diǎn)把命丟了。
Not only did he speak correctly,but he also spoke easily. 他不僅說得準(zhǔn)確,而且說得很輕松。
三、only放在不定式前面,常表示不愉快或出乎人們的意料的結(jié)果。
如 I went all the way to his home only to find hime out at a meeting. 我徑直到他家里去,不料發(fā)現(xiàn)他出去開會(huì)了。
I hurried to the post office only to find it closed. 我匆忙趕到郵局,不料已經(jīng)關(guān)門了。
She went home only to find her house burglarized. 她回到家里,發(fā)現(xiàn)房子被盜了。
四、“too...to...”結(jié)構(gòu)中,表示否定意思,但在“only too...to...”結(jié)構(gòu)中,only too = very,表示肯定意思。
如 The patient is too weak to walk. 那個(gè)病人太虛弱了,走不動(dòng)。
We are only too willing to do it for you. 我們非常愿意為你做那事。
I am only too delighted to accept your king invitation. 我非常高興地接受你的邀請(qǐng)。
五、在“one of + 復(fù)數(shù)名詞 + 定語從句”的結(jié)構(gòu)中,定語從句一般被看作修飾復(fù)數(shù)名詞,謂語要用復(fù)數(shù)形式。
但在“the only one of + 復(fù)數(shù)名詞 + 定語從句”的結(jié)構(gòu)中,定語從句卻被看作修飾“the only one”,謂語動(dòng)詞要用單數(shù)形式。
如 This is one of the best novels that have been published in the past two years. 這是近兩年出版的最好的小說之一。
He was the only one of the boys who was given a prize. 他是這些孩子中唯一受到獎(jiǎng)勵(lì)的。
She is the only one of the girls who has been to the US. 她是那些女孩中唯一去過美國(guó)的。
六、If only 為虛擬語氣的一種,表示愿望或一個(gè)未實(shí)現(xiàn)的條件,多用于感嘆句,其主句常常省略。
如 If only she would marry me! 她要是能和我結(jié)婚該多好! If only he had known about it! 他那時(shí)要是知道這件事該多好! If only you could have been here earlier that day! 要是你那天再早點(diǎn)到這就好了。
If only there were forty-eighty hours in a day. 要是一天有48個(gè)小時(shí)就好了。
