　　If you dig down deep enough into the earth, you will find rock. Over the top of most of this rock there is a layer of soil, like icing on a cake. You may call it earth or dirt, but the real name is soil.

　　The top layer of this soil is not very deep, but it is one of the most important things in the world. To grow well, plants need good topsoil. First, topsoil is made of little pieces of rock. Wind and sun, ice and water and plants have slowly broken big rocks up into little pieces. Then, these little pieces of rock have become mixed with many other bits of things：crumbled(粉碎的)pieces of dead plants and dried leaves, even dead insects and other dead animals. So the topsoil is bits of rock mixed with humus that used to be living things.

　　In some places earthworms are helpful in making good soil. As they crawl through the earth getting their food, they. make little tunnels that air and water come through. And they turn the soil over in such a way that rock pieces are slowly pushed to the top. Besides, earthworms grind up the soil as they eat.

　　If you put some soil in a glass of water, the rock, which is heavier, falls to the bottom of the glass. The humus, which is made of lighter things, floats on top.

1．The layer which spreads over most of the rock is called ________.

[　　]

A．topsoil

B．soil or dirt or earth

C．the icing of a cake

D．humus

2．Soil－making mainly depends on ________.

[　　]

A．earthworms

B．wind and sun

C．ice, water and plants

D．both B and C

3．According to this passage, earthworms are helpful to the soil in ________ ways.

[　　]

4．Humus is made of ________ plants, leaves, insects, animals etc.

[　　]

5．What will happen if you put a handful of topsoil in a glass of water?

[　　]

A．The humus comes above the rock bits.

B．The humus sinks down to the bottom.

C．The rock pieces float on the top.

D．The rock bits and the humus become mixed.

Stanley is one of the oldest villages in Hong Kong. Even a hundred and fifty years ago it was a large fishing-village. People called it Chik Chu. The village has changed a lot since the arrival of the British in 1841. When the British sailors came in that year, they began to call the village Standley. Lord Standley was a famous Englishman at that time. English people have called it Standley since then. Chik Chu was a good place for fishing boats. Many fishermen kept their junks(大帆船) at Chik Chu and others made homes there. Because there were many caves near Chik Chu, pirates(海盗) lived there, too.

The name of the most famous of all the pirates was Cheung Pao Tsai. He lived in Chik Chu nearly two hundred years ago and he had over six hundred ships and eighty thousand men. Cheung Pao Tsai was brave, but he was also very cruel. He captured many rich people. He wanted their friends to pay him a lot of money. If they did not do so, he took his prisoners to a high rock in Standley Bay. He made them jump into the sea from this rock. Today you can see the Hwai Jen Shih rock at Standley.

　　People in Mutsuhito, Japan, lived through one hundreds, and sometimes thousands, a day．But they couldn’t get used to it．

　　What was it? It was a string of earthquakes that made the small town shake all the time．This went on for more than a year．Sometimes the quakes were very small．Only certain instruments could pick them up．At other times, the quakes damaged houses and land．The people were always afraid．They wished they knew how to stop the ground from shaking．

　　People all over the world would like to know when an earthquake is coming．But an earthquake is almost always a surprise．Under the surface of the Earth, huge blocks of rock drift apart or slide against each other．The ground above splits apart or rumbles and shakes．

　　Some scientists hope to predict quakes by keeping a close watch on animals．It seems that some animals can sense an earthquake coming．In 1969, animals in a Chinese zoo began to act funny one day．Swans flew out of their pond．A panda sat down, covered its eyes with its paws, and groaned．The animals seemed to know that something was about to happen．And it did．An earthquake struck．What was it that the animals sensed? Scientists are trying to find out．

　　Keeping close track of the Earth’s magnetic force in earthquake areas may also help．A few years ago, in Hollister, CA, scientists kept a record of the area’s magnetic pull．For one week, the force grew stronger．Then it weakened suddenly．A day later, an earthquake struck．

　　It may become possible to know when and where an earthquake will happen．But it will be much harder to stop one from happening．

　　Many scientists think that the Earth’s covering is not smooth．They say the earth’s “skin” is made up of huge puzzle pieces called plates．Land and ocean floors make up these huge plates．Under the Earth’s crust(外壳), or plates, is hot rock．The plates float on top of this rock．Sometimes the rock forces its way through the crust．What happens then? A volcano is born! More often, the rock moves and forces the plates to pull away from each other, causing earthquakes to happen．(Volcanoes and earthquakes often go together．)

　　Sometimes, the plates end up on top of each other．When this happens, the land above may look strange．Seen from the air, there seems to be a long scar in the Earth．This is called a fault(断层)．The areas along faults have more earthquakes than other parts of the Earth．

　　For now, we’ll just have to shake along with the Earth．It goes through millions of small earthquakes every year．With luck, you won’t feel a thing!
