小博士：细心的同学们肯定发现了有些名词有单数(singular)和复数(plural)两种形式，而有些名词只有单数形式，这是怎么回事呢？让我来告诉你吧。英语中，名词按其所表示的事物的性质，可分为可数名词(countable noun)和不可数名词(uncountable noun)，可数名词有复数形式，不可数名词一般没有复数形式。名词单数变复数的变化规则见下表。

比一比，看谁写的单词多！

 A punctual person is in the habit of doing a thing at the correct time and is never late for anything.

   An unpunctual man never does what he has to do at the right time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be got back. Time is more useful than material(物质) things. In fact, time is life itself. An unpunctual man is always wasting his most important things as well as others’. An unpunctual person is always saying unhapppily that he finds no time to answer letters or return calls. But the man who really has much to do is very careful of his time. He knows that he can not finish all his work unless he carefully does every piece of work.

Being unpunctual is the sign of disrespect(不尊重) towards others. If a person is invited to dinner and arrives later than the time when he should be there, he keeps all the other guests waiting for him. Usually this will be thought as a great disrespect to the host and all the other guests.

   Not like a punctual person, an unpunctual one can’t do his duty wonderfully, whether it is public or personal. Imagine how it would be if those who should do important tasks failed to be on time. A man who is known to be often unpunctual is never believed by his friends or fellow men.
