Emphasizers are normally positioned prior to a predicate or constituent they emphasize, adding to its force, as shown:
1a. 那个台湾歌手的确唱得好,赢得了听众的热烈的掌声。
Nàgè Táiwāi gēshǒu díqù chàng de hǎo, yíngdé le tīngzhòng de rèliè de zhǎng shēng.
(That singer from Taiwan really sang so well that he won the audience’s ardent applause from time to time.)
1b. 那件事我真的不知道。
Nà jiàn shì wǒ zhēnde bù zhīdào.
(I really do not know anything about that matter.)
1c. 那明明是事实,他怎可抵赖呢?
Nà míngmíng shì shìshí, tā zěnkě dǐlài ne.
(That is obviously a fact, how could he try to deny it?)
