回複：再問兩個字，老師們幫我看看是中性還是貶義詞呢？謝謝

1） While been asked if he knew Ms A before the accident, Mr Robert denied.

是否可以改為：When asked if he knew Ms. A before the accident, Mr. Robert answered "No."

說明：“Deny”什麽？是問題？問題是用不著“deny"的。

2) Mr Robert claimed he did not meet Ms A on 2 July 2011.

是否可改為：Mr. Robert claimed that he did not know Ms. A until July 2,2011. 

說明：沒有前文，不知道是不是改句的意思。
