Toys and games are fun, but inventing them is serious business. Big toy companies treat it even more serious, because the more toys they sell, the more money they make. They have adults who do nothing but think up new toys. Sometimes they even work in locked rooms so no one can steal their ideas!

But not every new toy is invented that way. Some of the best inventions are made by kids.

Thirteen- year old Casey Golden loved to play golf(高尔夫). He invented a way to make the game more fun. He Invented a new golf tee(球座). It is called the Bio tees Most golf tees are made from wood, but Casey’s tee is made out of recycled paper. It does not harm the environment. Casey started his own company to make his new tee. He’s already had orders for millions of them.

Jessica Peach invented a toy when she was only eight. Jessica likes to jump rope. She jumps alone and she jumps with friends. To jump alone, you need a short rope. With friends, you need a long rope. So Jessica invented a new kind of jump rope. The length of Jessica s jump rope can be modified. It can be made long to jump with friends. Or it can be made short to jump alone. When you are done jumping, you can even turn the jump rope into a belt(带子), Now Jessica has a business to sell her jump ropes.

Do you know some great inventors and their inventions?

What factors (因素) are needed for their success?

Well, good timing for a start. You can have a great idea which the public simply doesn’t want ... yet. The Italian Giovanni Caselli invented the first fax(传真)machine in the 1860s. Although the machine was excellent, his invention quickly died a commercial(商业的) death. It was not until the 1980s that the fax became very common in every office... too late for Giovanni Caselli.

Money also helps. The Frenchman Denis Papin (1647-1712) had the idea for a steam engine (蒸汽机)almost a hundred years before the better-remembered Scotsman James Watt was even born... but he never had enough money to build one.

You also need to be patient (it took scientists nearly eighty years to develop a light bulb which actually worked)... but not too patient. In the 1870s, Elisha Gray, a professional inventor from Chicago, developed plans for a telephone. Gray saw it as no more than “a beautiful toy”. However, when he finally sent details of his invention to the Patent Office(专利局) in February， 1876, it was too late. Almost the same invention had arrived two hours earlier... and the young man who sent it, Alexander Graham Bell, will always be remembered as the inventor of the telephone.

Of course what you really need is a great idea—but if you haven’t got one, a walk in the country and careful look at nature can help. The Swiss scientist, George de Mestral, had the idea for Velcro（魔术贴）when he found his clothes covered in sticky seed pods after a walk in the country. During a similar walk in the French countryside some 250 years earlier, Rene Antoine Ferchault de Reaumur had the idea that paper could be made from wood when he found an abandoned wasps’ nest（蜂巢）.

You also need good commercial sense. Willy Higinbotham was a scientist doing nuclear（核能的） research in the Brookhaven National Laboratory in Upton, USA. In 1958, the public were invited to an exhibition in the Laboratory to see their work, but both parents and children were more interested in a tennis video game on the screen. Soon hundreds of people were ignoring the other exhibits to play the first ever computer game—made from a simple laboratory instrument called an “oscilloscope”. Higinbotham, however, never made money from his invention: he thought people were only interested in the game because the other exhibits were so boring!

1.How many factors do inventors need according to the passage?

A. 3.　　 B. 4.　　 C. 5.　　 D. 6.

2.The word “ignoring” in the last paragraph probably means “_____”.

A. having no idea of　　 B. doing no good to

C. getting no chance of　　 D. paying no attention to

3.What can you learn from the passage?

A. Giovanni Caselli invented the first fax machine in the 1980s.

B. Denis Papin afforded to build a steam engine a hundred years ago.

C. Elisha Gray missed the chance to be the inventor of the telephone.

D. George de Mestral got an idea from a walk in a French countryside.

4.Which of the following would be the best title for the passage?

A. How to be a successful inventor

B. How to get a great idea from nature

C. How to have a good commercial sense

D. How to make money from inventions
