常見錯誤

What are common mistakes with "Antibiotic"?Which "Antibiotic" sentences look correct but are wrong?

×I need antibiotic for my infection.

I need an antibiotic for my infection.

作為可數名詞,單數形式前通常需要不定冠詞 'an'。

×The doctor gave me some antibiotic.

The doctor gave me some antibiotics.

當指具體的藥物(藥丸、藥劑)時,'antibiotic' 通常以複數形式 'antibiotics' 使用,因為它通常是可數的。

×This is antibiotic against bacteria.

This is an antibiotic for bacterial infections. / This antibiotic works against bacteria.

描述抗生素的用途時,更自然的搭配是 'for (treating) infections' 或 'works against/fights bacteria'。

×The antibiotic are effective.

The antibiotic is effective.

主詞 'antibiotic' 是單數,動詞必須使用單數形式 'is'。

×I took an antibiotic for my flu.

I took an antibiotic for my bacterial infection. (Antibiotics don't work for viral flu.)

常見的概念錯誤。抗生素只對細菌感染有效,對病毒引起的疾病(如流感、普通感冒)無效。

×This is an antibiotic medicine.

This is an antibiotic. / This is an antibiotic drug.

'Antibiotic' 本身已指藥物,加上 'medicine' 略顯冗餘。更自然的說法是直接稱其為 'an antibiotic' 或更正式地 'an antibiotic drug'。
