［误］ Today's date is January first. 1998.
［正］ Today's date is January 1， 1998.
［正］ Today's date is January 1st， 1998.
［析］ 在日期书写中不要用序数词全写，而要用1st， 2nd， 3rd……如果一定要用序数词，其顺序应为：It is the first of January.

［正］ This is a book about everyday English.
［正］ This is an everyday English book.

［正］ My father has been dead for ten years.
［析］ die是瞬间动词，它可以用于完成时，如：My father has died. 但用于完成时不能与表示一段时间的状语连用。它也可以用于过去时，如：My father died three years ago
［误］ We'll always remember the deads who were killed in the war.
［正］ We'll always remember the dead who were killed in the war.
［析］ 形容词前如加定冠词表示一类人，如the rich(富人)，the sick(病人)，the poor(穷人)，其后的谓语动词要用复数，如：The rich are not always happy.
dead deadly
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.
