71__ One of the best things you can possibly do is to start you own club．It’s great fun especially if you are the sort of person who feels there’s never anything to do during the school holidays．

The first thing you need to come up with is an idea for your club． 72 . Pets, clothes, pop music or dancing groups, sports, making things? The list is endless．

Next you need some friends to be in your club with you．  73 .  All you need is three or four other people who are interested in the same thing as you．

   74  . You should all sit down somewhere together with lots of pieces of paper and write down every name you can think up．That’ll keep you busy for ages．

At your first meeting you should make up a rule book．And the first rule should be no grown-ups or little/big brothers or sisters! The best clubs are always secret!

Now you have just about everything you need, except membership cards．These are very important and again you can spend a lot of time making them．    75  .Why not leave some space for a photo of yourself? That will make the membership card really look like it．

So there you are, get clubbing! Once you get started you’ll think of loads of more interesting things to do!

A.  That’s easy．

B.  Enjoy your own club!

C.  Invite a designer to join you．

D.  What are you interest in?

E.  Some vacation is coming．

F.  Then you need to pick a name for your club．

G.  Use a bright thick pen to make a special design．

71  People use money to buy food, furniture, books, bicycles and hundreds of other things they need or want. When they work, they usually get paid in money.

Most of the money today is made of metal or paper.    72 One of the first kinds of money was shells.

Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Elephant tusks, monkey tails and salt were used as money in parts of Africa.

The first metal coins were made in China. They were round and had a square hole in the centre. 73    Different countries have used different metals and designs for their money. 74  Sweden and Russia used copper (铜) to make their money. Later some countries began to make coins of gold and silver.

But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money.  75   The first paper money looked more like a note from one person to another than the paper money used today.

Money has had an interesting history from the days of shell money until today.

E. Money, as we know, is all made of paper.

F. They began to use paper money.

G. Today anyone will accept money in exchange for goods and services.

__71__    From 18－25, according to I．Q. scores；but you are wiser and more  experienced with increasing age.

You are smartest in your 20's; around 30, your memory begins to go down, particularly your ability to perform mathematical computations.   __72__   Your vocabulary at the age of 45, for example, is three times as great as when you graduated from college. At 60, your brain possesses almost four times as much information as it did at the age of 21.

__73__   You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 49.

Before the age of 24, we believe that our happiest years are yet to come；over 30，we believe that they are behind us. A National Health survey agrees: after the age of 30, we become more realistic and do not view happiness as a goal in itself. If we maintain our health, achieve professional and emotional goals, happiness, we feel, will follow.

__74__   Generally between 30 and 39，but the peak(顶峰) varies with different professions.

Mosart wrote a symphony (交响曲)  and four sonatas by the age of 8, and Mendelssohn composed his best­known work A Midsummer Night's Dream, at 17, but most of the great music  was written by men between 33 and 39.

Though the peak in most fields comes early, most Nobel Prize winners did their top research in their late 20's and 30's—creative people continue to produce work with high quality throughout their lives   __75__

A. When are you most creative (创造性的)?

B. When are you happiest?

C. When are you smartest?

D. Do you know what I．Q. refers to?

E. But your I．Q. for other tasks goes up.

F. Creative people usually produce a lot of works.

G. For the “well­conditioned mind”， there is no upper    limit.
