题目内容

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（物体）. The water movements of the 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 on a 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.”

It’s about Time

Do you know what time it is? If you do, you probably are looking at a clock or Long ago, people didn’t have clocks or watches like you do. When the sun rose, they got up and when the sun went down, they went to bed. They told timeby the position of the sun in the sky.

People discovered that they could use a stick and the sun to tell time. This was called a shadow clock. They put a stick in the ground, pointing straight up. The direction of the stick’s shadow and how long or shortit was told them the time.

A better kind of shadow clock was called a sundial. Sundial had a pointer and a base. The pointer cast a shadow on marks around the base. People could tell time by reading the marks.

But shadow clocks were not good for telling time on cloudy days or at night.

One kind of clock that didn’t need the sun was a water clock. A water clock was container with a tiny hole in the bottom. Water would steadilydropout of the hole. Marks on the inside of the container showed the time. It took one hour for the water to go down one mark.

Another kind of clock that didn’t need the sun was a candle clock. You would know the time by how much of the candle had melted（熔化）. The candle had marks down its side to show the hours.

Sometimes people used candle clocks as alarm clocks. They put a nail（钉子）in the candle at the time they wanted to wake up, hanging a shoe on the nail. When the candle melted down, the nail fell outand the shoe hit the floor with a BANG! Now there are all kinds of timepieces, from tall grandfather clocks to watches we wear on our wrists（手腕）. Most clocks run on electricity from batteries.

There are many more types of clocks, too. Clocks hang in and on buildings. Clocks are everywhere!

Television is one of the greatest technological inventions of the 20 century. A Scottish man called John Logie Baird invented it. Inventors in the USA and Europe were working on electronic television systems but Baird used a mechanical(机械的) system. In 1925, he was able to send the first black and white picture—of the head of a doll—from one end of his flat to the other. He then used a local office boy, not the doll, and this teenager was the first person ever to appear on TV.

In January 1926, Baird invited scientists to his flat and showed them his invention. He called it a “televisor”. Later that year, Baird started the world’s first TV station and gave it the name 2TV. In 1927, he sent images 730 kilometres from London to Glasgow using telephone cables(电缆). A year later, his company sent the first transatlantic(大西洋彼岸的) TV images from London to New York. Baird made the first television programmes for the BBC in 1929. These programmes had sound, not just pictures.

However, Baird's system was very limited and basic( 基本的). A totally electronic American system was more popular and practical. The inventor of this electronic system was an American, Philo Farnsworth. In 1936, the BBC started using Farnsworth's system because the picture was better than Baird’s.

More and more people had televisions after the Second World War. Colour TV began in the USA in the 1940s but only a small number of people had colour televisions in their houses. They were very expensive. In Britain and the USA, the first regular(有规律的) colour TV programmes only began in1967.

Now in the 21 century, we have digital television. TV has changed a lot since the face of a boy appeared on TV in John Logie Bairds flat.
