呢句既grammar岩唔岩ar?

If someone says they have never told a lie, then they are actually telling a lie.

Singular "their" etc., was an accepted part of the English language before the 18th-century grammarians started making arbitrary judgements as to what is "good English" and "bad English", ... And even after the old-line grammarians put it under their ban, this anathematized singular "their" construction never stopped being used by English-speakers, both orally and by serious literary writers. So it's time for anyone who still thinks that singular "their" is so-called "bad grammar" to get rid of their prejudices and pedantry!

tense: 我用says而唔用said,　因為你應該覺得這個假設係「幾時都正確」的,　所以不使用past tense。
要表達「從來無講大話」:　噤就一定要用never ( present perfect tense),去加重語氣啦!
你用she,噤someone係he,又如何?或者情況調轉又怎麼辨?為了避免將someone寫成he or she, his or her, 於是很多English-speakers(尤其係對話時)都用they/ them (or em)/ their當singular form噤用。雖然曾經很多反對的聲音,　但致今亦逐漸地被接受。　
actually解「實際上」,　令句子更加全神。

但係如果作文時,就適宜避免噤用,　以防被當作錯誤的用法。

另一個不用分性別的寫法, 就是用ONE字。

If one says one has never told a lie, then one is actually telling a lie.

one = pron. (代名詞 pronoun) (名詞 noun) 一個人,任何人
One can not learn a language well unless one works hard.
學好一種語言非下苦功不可。

問題的例句和我的譯本都是指說話者對「一般情況」的看法, 而並非講述某一次。

如果係指某一次 (而又已知telling a lie是事實), 根本不需要用if, 時式更加要改做past tense。

He said he had never told a lie, but actually he was telling a lie.

2008-09-25 08:42:31 補充：
我的譯本之所以寫得噤肯定 (無probably), 完全因為我覺得這是說話者對「一般情況」的判斷, 他認為這是「最有可能的結果」, 所以連probably都不用。 如果用, 就不能有效地反映出說話者講此番話時對自己推斷的信心。言下之意, 說話者很有信心, 這就是事實。

很多English-speakers(尤其係對話時)都用they/ them (or em)/ their當singular form噤用

實例: Longman Dictionary > no (adverb)

7. won't take no for an answer if SOMEONE won't take no for an answer, THEY are determined that you should agree to do something:

用 they 去代表 someone

http://www.ldoceonline.com/dictionary/no_1 > no (adverb) > 第7個解釋

If she is said to be not telling lies, she is probably telling lies then.

係我就會寫
She's probably lying if she said "I am not lying.".

If someone says they have never told a lie, then they are actually telling a lie.
引用上面o的答案(個have 要用had)
如果你真係想寫一個concept, 我都會用呢個.
但係如果你係寫緊一個situtation o的話, 用個呢個可能會好o的.

好睇你點睇: probably定fact
我就覺得係probably.
你覺得係fact o的話
就可以用: If someone says they had never told a lie, they are telling a lie for sure.
咁樣o的話你讀果陣個sure 係後面就可以加重語氣
我會唔用then 都唔洗因為個then 我覺得會斬左句野做一半
不過你好驚佢mark 你 grammar 錯就加返 then 啦

寫呢o的野好睇你寫緊乜野,係乜情況. 因而先可以選擇用咩字先最合適

I would rather say :

If someone said (that) she did not tell lies, then she is probably telling a lie.
