菜鸟问语法 真题－0208－25 and 37

bailiyan

请教一下,多谢!

25. Rarely has a technological development had as great an impact on society as the rapid grow of

       A                            B              C                     D   

electronics.

请教一下:答案是D,但是我觉得B也有错,B中的has 与Rarely has 中的has谓语重复

不明白这句话的结构,麻烦帮忙详细分析一下,多谢!

37.   Only with early seventeenth-century observers did the music of the original inhabitants of the United

             A                      B                       C

States and Canada entered recorded history.

答案是D,entered--enter(原形),不明白:倒装句子前面有个did 了,为什么后面又一个enter]呐?不是谓语重复了?为什么要改成原型呐?很不明白???

25Rarely has a technological development had as great an impact on society as the rapid grow of  electronics.

       A                            B              C                     D   

答案是D,grow一看就应该是growth. B没错, 还原一下,句子是: A technological development rarely has had as great an impact on society as the rapid growth of  electronics. 第一个HAS是表示完成时态,第二个HAD是有实际意义的"有"的意思.

37.   Only with early seventeenth-century observers did the music of the original inhabitants of the United

             A                      B                       C

States and LACE>CanadaLACE> entered recorded history.

Only with early seventeenth-century observers ONLY+状语提前,句子全倒装(如果仍不明白,仔细看一下有关倒装句介绍)~~ 前面有DID,后面就只能是ENTER. 还原句子:the music of the original inhabitants of the United States and LACE>CanadaLACE> entered recorded history only with early seventeenth-century observers

谢谢!多谢!我找了有关倒装句介绍,介绍比较简单,呵呵,我也笨了点^_^

但是还是不明白,did在这里是做什么成分?

为什么前面有DID,后面就只能是ENTER原型?

因为did已经代表了过去时太罗！enter就不用了

你死记住就是！

好笨哟,我还是理解不了,麻烦哪位好心的高手帮我详细解释一下

或者哪位能够贴个此类倒装结构讲解的帖子给我?感激ing^_^

hmm

一般形容词，副词和介词短语等置句首后面要部分倒装，也就是一般时的do/does,过去式的did, 现在完成时的has/have, 过去完成时的had和将来时的will要提到主语之前，这时do/does/did/will后面动词都是原形，has/have/had后还是过去分词形式。如果是系动词可能就算是全倒装了，如Among sth2. is/are sth.1

我说的不一定对，LZ可再拿本语法书看看，或是用关键词“倒装”去google搜。
