［正］Today's date is January 1st, 1998.

dead在某些词组里是“完全”、“的确”的意思，如dead right, dead tired, dead sure。而deadly则是“致命的”，如：The rich man had many deadly enemies. 又如：Cancer is a deadly disease.
dead, died
dead是形容词，如：Mrs Ginty was dead. 而died是动词die的过去式及过去分词，如：She died in 1960.但英语中如表达出对某人去世的伤感说法是pass away, 如：My father passed away, this morning.
