Garbage(垃圾) Island

You can’t see it from the air. It’s almost impossible to see from a ship. But somewhere in the North Pacific is a huge island of garbage, just below the water surface.

What is the island made of?

The garbage island is not an island, but a collection of millions of plastic and other objects. The water movements of Pacific Ocean bring the objects together and cause them to go around in a big circle.

Charles Moore found it in 1997 and named it “the Great Pacific Garbage Patch” .

Where does all the plastic come from?

Much of the garbage comes from everyday objects, such as shopping bags and water bottles. Some of these objects finally reach the ocean. Garbage from the western coast of North America takes about six years to reach it. Objects from East Asia take about a year. Other garbage comes from ships passing through the area.

Is the Garbage Patch dangerous?

The larger pieces of garbage are a problem for wildlife. For example, sea turtles（海龟）and seabirds often think the plastic is their food. They eat the plastic and die.

In addition, the plastic stops sunlight from reaching deeper water. Without sunlight, very small sea animals die. Then, there is less food for larger fish to eat.

What can we do to help stop it?

Cleaning up the island isn’t easy. But we can make people realize the problem. One environmentalist(环保主义者), David de Rothschild, is sailing around the world in boat made of plastic bottles to teach people about the problem of garbage in the sea.

Another idea is that we can recycle the plastic garbage. Environmental engineer Cesar Harada is building a robot that collects pieces of plastic. Harada hopes to use his robot in the Pacific. Harada also has a website for reporting environmental problems. He says, “I hope everybody can become an environmental activist.”

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 quality is 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 a 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 tiny 120cm screen with a white dot which could be hit back and forth over a “net” using a button and a knob. 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?

A. 3. B. 4. C. 5. D. 6.

【2】The word “ignoring” in last paragraph probably mean?

A. having no idea of B. making no sense 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 the idea from a walk in a French countryside.

【4】What is 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 good commercial sense.

D. How to make money from inventions.
