通常話D人英文錯咗 會話 bad com?????

真正的說法應該是:

He/she has a bad command of English .....

第一個網址有以下例句:Speaking Singlish in those ways does not mean having a bad command of English. Sure, it isn t proper, but if you can switch to proper English if need be, you don't have a problem.

第二個網址是字典網站, 有以下例句:She has an impressive (= good) command of the English language.

gj: (1) 發問者的提示是 「bad com ?」, 不知你如何接那 com..的下文呢? 回答問題是要兼顧發問者的要求呢. (2) 又請閣下以後正面提供怎樣說才「對」, 而不是只說別人錯. (3) btw, 你能具體補充上次說的甚麼 「someone can UNDERMINE hk people s english competency」 就更好了, 不要一再避重就輕, 否則只會顯得自己的擇「錯」而執 :)

very detail

bad command of English 係話人整體英語掌握得不好 (看看你的例子吧), 並非話別人的英文錯左 wrong/incorrect or misusage.
