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).

Born to Travel

Burton Holmes was a born traveller if ever there was

one. He was born in Chicago in 1870. When he was 16, his

grandmother took him to Europe. He took a camera with him, and took pictures. When he was 17, he went to Europe again with his grandmother. That year they also went to California and to Cuba.

Burton was on the road all the time after that. Everywhere he went, he took at least one camera. Then Holmes began giving talks to the Chicago Camera Club. His talks were so popular that he decided to build a business on them.

Holmes’s first travel pictures were on glass slides(幻灯片). These were in black and white. Then he decided to have the slides painted so that his pictures would appear in colour. A few years later, in 1897, Holmes began showing moving pictures of his travel experiences. This was only a year after movies first were shown to a group of people in New York. Later, he set up a film company and his films became popular. There is even

a star with his name on Hollywood Boulevard. In 1910 Holmes published a set of books about his travel experiences. These books also included the general travel information for others to follow.

Burton Holmes had many adventures over the years. He took pictures at the first modern Olympics, in Athens, Greece, in 1896. In 1899 Holmes took the first moving pictures of a war. He was the first person to take moving pictures in China, and the first person to drive a car in Denmark. He photographed the opening of Yellowstone National Park, in 1916. When things happened, Burton Holmes was there. In travelling for 62 years Holmes kept time in his photographs, saving it for generations to come.

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.”
