Structure

This structure is usually used for emphasizing how little of something you have. The measure word in the middle of the sentence and the noun should be compatible with the verb at the end.

Examples 
wǒ yī jù zhōnɡ wén dōu bú huì shuō.
我一 句 中文 都 不 会 说。
I can't speak one sentence of Chinese.

Structure 
If you want to put the topic of your conversation at the beginning of the sentence, make sure it has a strong emphasis or some kind of exaggerated remark.

Examples
Zhè ɡè rén wǒ yī cì dōu méi jiàn ɡuò.
这 个 人 我 一 次 都 没 见 过。
I haven't seen this person once.
