四级英语语法精解（三）

       
        1） 含有否定意味的词置于句首，主谓倒装。
       
         同学们应注意常用否定词语，如：hardly, barely, not, seldom, little, few, nowhere, never, atno time, by no means, in no way, in no case, under no circumstances, not until,not only… but also.., neither … nor…等。如果是在从句的句首，则从句倒装，如4）题。
       
        2） only + 状语置于句首，主谓倒装。
       
        Only后的状语可以是单词、短语，也可以是从句，要特别注意，从句并不倒装，而是主句倒装。如：
        Only when the war was over was he able to get happily back to work.
       
        3） Neither/So置于句首倒装，表示"也/也不……"，如上面的2）3）题。
       
        4） There/here/then或做状语的地点副词和地点介词短语置于句首，要全部倒装。如：
        There stands a monument in the center of the square.
        Down came a light form the ceiling when he was walking across the floor.
        On the hay lay a wounded boy of not more than seventeen.
        5） 现在分词和过去分词可提至句首构成"分词+ be + 主语+其它+的倒装句式。如：
        Enclosed in the letter was a photo of a beautiful girl.
        Glooming in the test tube on the table was the mysterious something which theyhad been working so hard to find, radium.
       
        6） so/such…. that句型中，so + 形容词/副词提前，主谓倒装。如：
        So boring was the speech that the audience all left halfway.
        Such a noise did they make that the neighbors could not go to sleep at night.
