在英语中,倒装是一种常见的语法结构,用于强调句子中的某一部分。但是,在有些情况下,我们需要在倒装结构中加入助动词do。
什么是倒装?
倒装是指将谓语动词放在主语之前的语法结构。在肯定句中,倒装通常用于强调句子中的某一部分;在疑问句中,则是用于构成句子。
例如:
-
Normal: She sings very well.
-
Inverted: Very well she sings.
-
Normal: They are playing soccer.
-
Inverted: Playing soccer are they.
-
Normal: He has never been to Paris before.
-
Inverted: Never before has he been to Paris.
为什么要使用倒装?
倒装结构可以强调句子中的某一部分,使其更加突出。倒装通常用于以下情况:
-
在句首强调状语:
- Never before have I seen such a beautiful sunset.
- In the garden sat a little boy.
-
在句首强调动词:
- Up the stairs ran the little girl.
- Over the hill walked the old man.
-
为了避免重复使用某些词语:
- In the room were two chairs and a table.
- On the table sat a vase of flowers.
但是,在某些情况下,我们需要在倒装结构中加入助动词do。
什么时候要使用do的倒装?
当我们需要将谓语动词放在主语之前,并且谓语动词是动词原形(不带词尾-s或-ed)时,我们需要在倒装结构中加入助动词do。
例如:
-
Normal: He sings very well.
- Inverted: Very well does he sing.
-
Normal: They play soccer every weekend.
- Inverted: Every weekend do they play soccer.
-
Normal: She wrote a letter to her friend.
- Inverted: To her friend did she write a letter.
在这些情况下,我们需要加入助动词do来构成倒装结构,以便使句子更加自然。
总结
