在學(xué)習(xí)英語(yǔ)的過(guò)程中，我們常遇到only與其它詞或結(jié)構(gòu)搭配來(lái)表達(dá)不同的意思，現(xiàn)將這些用法示例如下：
　　一、only引導(dǎo)的詞組或句子放在句首作狀語(yǔ)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(guò)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(guò)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(shuō)得準(zhǔn)確，而且說(shuō)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(yǔ)從句”的結(jié)構(gòu)中，定語(yǔ)從句一般被看作修飾復(fù)數(shù)名詞，謂語(yǔ)要用復(fù)數(shù)形式。但在“the only one of + 復(fù)數(shù)名詞 + 定語(yǔ)從句”的結(jié)構(gòu)中，定語(yǔ)從句卻被看作修飾“the only one”，謂語(yǔ)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(shuō)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(guò)美國(guó)的。
　　六、If only 為虛擬語(yǔ)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。
