7、，若整个谓语都在主语之前，则称为完全 倒装； 若谓语一部分(通常是助动词、 情态动词或 be 动词)位于主语之前， 则称之为部分倒装。 3完全倒装的应用场合 (1)there be 句型中，其中 be 可换作 appear，come，exist，happen，lie，remain，seem，stand， ring 等动词。 There stands a temple on the top of the mountain. 山顶上有一座寺庙。 There rings the bell.铃响了。 (2)由副词 here，there，now，then 等开头的句子，谓语动词是 be，come，fol

8、low，go，begin 等，且主语是名词时。 There goes the last bus.末班车开走了。 Here are some 这是一些图画书。 (3)表“动态”的副词 in，out 等置于句首作状语，且句子主语是名词时。 Out rushed the girl，crying.那个女孩哭着跑出来了。 注意代词作主语时，主谓语序不变。 In she came and the lesson began. 她走进来开始上课。 (4)表示地点的介词词组位于句首时。 In the north of the city lies a river.城北有条河。 In front of our ho

9、use stands a big tree. 我们的房子前有一棵大树。 (5)such 置于句首时(多被认为是表语，such 后的 be 动词应与其后真正的主语保持一致)。 Such is life！人生就是这样！ Such were his words.他就是这样说的。 (6)作表语的形容词、分词或介词短语置于句首时，此时倒装结构为“表语连系动词主 语”。 形容词连系动词主语 Present at the meeting were some important figures. 出席会议的是一些重要人物。 分词连系动词主语 Gone are the days when Chinese wer

10、e burdened with three mountains. 中国人民肩负三座大山的日子一去不复返了。 Sitting in front of the house was a little girl. 一个小女孩坐在房子的前面。 介词短语连系动词主语 Among the goods are Christmas trees，flowers，candles and toys. 这些商品里有圣诞树、鲜花、蜡烛和玩具。 4部分倒装的应用场合 (1)否定或半否定意义的副词或介词短语置于句首时，引起部分倒装结构。常见的词有以下几 种： 否定意义系列：no，nowhere，not，never； 否定意义

11、短语“绝不”系列： in no way， at no time， in no case， by no means， on no account， on/under no condition； 半否定意义系列：seldom，hardly，scarcely，barely，little，few 等。 By no means is she an inexperienced teacher. 她绝不是个毫无经验的老师。 Under no condition should you tell them what happened.你绝不能告诉他们所发生的事。 Seldom does he go to the

13、her is.不仅学生们在种树， 老师也在种。 neither.nor.连接两个分句时，两个分句都用部分倒装。 Neither have I seen him recently，nor have I heard from him.我最近既没见到他，也没收到他的 来信。 “hardly(scarcely/barely)when.”和“no sooner.than.”句型，意为“一就”。 当 hardly(scarcely/barely) 或 no sooner 置于句首时， 主句的谓语动词用部分倒装， 并且主句多 用过去完成时。 Hardly had we sat down at the tab

14、le when the phone rang.No sooner had we sat down at the table than the phone rang. 我们刚在桌子旁坐下，电话铃就响了。 not until 从句或短语在句首时，后面主句的谓语动词用部分倒装结构，而从句不倒装。 Not until she saw the present did she feel happy. 直到看到礼物，她才感到高兴。 注意：若 not until 句型用在强调句中，则不倒装。 It was not until she saw the present that she felt happy. 直

15、到看到礼物，她才感到高兴。 (3)“so形容词/副词that”和“such名词that”句型，意为“如此以至于”。 当“so形容词/副词”，“such名词”位于句首时，主句的谓语动词用部分倒装结构，但 从句不倒装。 So beautiful a girl/Such a beautiful girl is she that many young boys fall in love with her. 她是一个如此美丽的姑娘，以至于许多年轻小伙子都爱上了她。 (4)当副词 only 强调状语(介词短语/副词/状语从句)，并且置于句首时，主句谓语动词用部分 倒装。 Only when he retu

16、rned did we find out the truth. 只有到他回来时我们才发现实情。 注意：但如果 only 不用于以上结构，只修饰主语时，不用倒装。 Only his brother was right. 只有他的弟弟(哥哥)是对的。 (5)so/neither/nor 置于句首，表示前者情况也适用于后者，其句型为：so/neither/norbe 动词/ 助动词/情态动词主语。so 与前面的肯定句呼应；neither，nor 与前面的否定句呼应。 He has passed the exam，so have I. 他考试及格了，我也是。 If you dont do the wo

17、rk，neither shall I. 如果你不做这项工作，我也不做。 注意： 如果后一句只是单纯地重复前一句的内容， 对其肯定或附和， 此时译作“确实(如此)”， 则采用陈述语序。 John won the first prize in the contest.

19、时，其前不能加 冠词。 Beggar as he is，he looks very proud. 尽管他是个乞丐，但看上去很高傲。 (8)though 引导的让步状语从句可以倒装，也可以不倒装；although 引导的让步状语从句不倒 装。 Although we were tired，we kept walking.
