Unit 4 Grammar Inversion 语法精解 倒装 Inversion 英语句子的正常顺序是主语在前,谓语在后。把谓语放在主语之前就叫倒装结构。全部谓语放在主语之前叫全部倒装; 只把助动词或be 动词情态动词放在主语之前就叫部分倒装。 基本语序natural order subject 主+ predicate 谓+object 宾 I love you. 全部倒装 1. 用于 there be 句型。　 There are many students in the classroom. 原句自然顺序是：　 Many students are there in the classroom. 2. 由副词here，there，now，thus，then或in，out，away，up，off，down，back，over等开头的句子，谓语动词是be，come，follow，go，begin等，且主语是名词时。表示强调 Here comes the bus. There goes the bell. Now comes our turn. Out went the children. 注意： 主语为代词是, 主谓语序不变。 Here it is. In he comes. Here you are. 3. 当句首状语是表示地点的介词词组时,也常引起全部倒装。 North of the city lies a big steel factory. Beside the man sits a beautiful lady. Under the tree stands a little boy. 划线的均是表示地点状语的介词词组,并且是位于句首。 4. 表语置于句首时, 倒装结构采用“表语＋连系动词＋主语”的结构 形容词＋连系动词＋主语　 Present at the meeting were Professor Black, Professor Smith and many other guests. 2) 过去分词＋连系动词＋主语 Gone are the days when they could do what they liked. 3) 介词＋连系动词＋主语 Among the goods are Christmas trees, flowers, candles and toys. 5. 为了保持句子结构平衡,或为了强调表语或状语,或为了使上下文结构紧凑。 They arrived at a farmhouse, in front of which sat a small boy. Inside the pyramids are the burial rooms for the kings and queens and long passages to these rooms. 强调状语 保持句子结构平衡 1. 用于疑问句　 Do you speak English? 2. 用于省略if 的虚拟条件句 Were I you,I would drop him. 由 If I were you这样一个虚拟条件分句变过来的。 部分倒装 3. 用于“形容词(或名词、动词)＋ as (though)” 引导的让步状语从句。 Pretty as she is, she is not clever. Try as he would, he might fail again. Money as they had, they don’t know how to spend it. 4. 用于no sooner than, hardly when 和 not until的句型中。 No sooner had she gone out than the class began. Not until the teacher came did he finish his homework. 5. 用于 never, hardly, seldom, scarcely, little, at no time, not only, barely, rarely, little, not a bit 等否定词开头的句子里。 Seldom do I go shopping. Never shall I do this again. At no time can you say “no” to the order. Little do I dream I would see you here. ①not only...but also...连接两个并列分句时，前倒，后不倒。 Not only do I know the news ，but (also) the teacher does. ②not until...句型中前面的从句不倒装，后面的主句用部分倒装。 Not until I reached home did I find that I had lost the wallet.直到回到家我才发现钱包丢了。 ③no sooner...than...，hardly...when...句型后面的从句不倒装，前面的主句采用部分倒装。 Hardly had Tom got home when the phone rang. 汤姆刚到家，电话就响了。 6. 用于only开头的句子(only位于句首,修饰副词、介词短语或状语从句) Only in this way can you learn English well. Only when he told me did I realize how hard he was. 【温馨提示】only修饰的状语如果不是句子，或者修饰状语但不位于句首时，主谓也不倒装。 ... ...
