only＋状语置于句首引起的倒装句 副词only置于句首， 强调方式状语、 条件状语、 地点状语、 时间状语等状语时， 主句要进行部分倒装。如果被only所强调的状语为状语从句， 该状语从句不倒装， 只对主句进行倒装。例如： Only in a big city was it possible to buy a new wheelchair. 只有在大城市里才能买到新轮椅。 Only when we had studied the data again did we realize that there was a mistake. 只有当我们再次研究了这些数据的时候， 我们才意识到出了一个错。 注意： 如果放于句首的only所修饰的不是状语时， 该句不用倒装。例如： Only some of the children passed the examination. 只有几个孩子通过了考试。 速记英语单词 单词不用记 新概念英语青少版 强调句常用来突出说话人要强调的语言信息，给对方以强烈的印象和感受。译成汉语时，常加上“正是 …”等字眼。 do（does／did）＋v强调 只在一般现在时和一般过去式时中且只对肯定的谓语动词强调，无疑问和否定形式。 She did tell me about her address. 她确实告诉了我她的地址。 I did see the key on the desk this morning. 今天早上我看到桌子上的钥匙了。 1. ____ by keeping down costs will Power Data hold its advantage over other companies.
