The Ring of Fire covers 4,000 km around the edge of the Pacific Ocean．It includes the countries of Japan，Indonesia and the Philippines．More earthquakes and volcanoes occur in this area than anywhere else in the world．The name Ring of Fire refers to areas below the earth's surface．These areas move suddenly and often cause earthquakes and create volcanoes．
Many areas of Asia，such as the Philippines，Japan，and Indonesia, sometime experience earthquakes and volcanoes．There are occasionally landslides(泥石流)，mudslides，and tidal waves as a result．Fortunately, these natural disasters do not happen very often．
Southern China is about 600 km away from the Ring of Fire．Sometimes, people in this region feel earthquakes too．The worst earthquake felt in southern China was in 1918 in Shantou．It measured 7.3 on the Richter scale．Any earthquake of 6 or more on the Richter scale is very dangerous to people．
People in Hong Kong sometimes experience the effects of earthquakes and volcanoes．In September 1994，for example，the strongest earthquake to hit Hong Kong for 76 years shook buildings and scared thousands of residents．Frightened workers and families ran out of their offices and homes．The earthquake measured 6.5 on the Richter seal．
It is difficult to predict when an earthquake will occur In countries within the Ring of Fire, buildings must be very strong because the effects of earthquakes on buildings are terrible．
In June 1991, Mt Pinatubo in the Philippines erupted．Many people were killed and the area surrounding the volcano was badly damaged．Hot ash and liquid rock from the volcano forced people to leave the area．They only returned many months later．The ash spread over a large area．Even people in the Guangdong region of southern China saw ash in the air．

The following conversation is between Susan Russell-Robinson from the US Geological （地质学的）Survey and Barbara Reynolds from USA Today .
Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt（喷发）in 1991 ?
A: Volcanoes （火山）each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years .
Q: So nothing caused it ?
A: There’s nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that .
Q: What is “the ring of fire” ?
A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world’s volcanoes lie .
Q: Why such a concentration（集中）there ?
A: That’s based on a theory that the oceans and the continents are like separate pieces . When they move , one might ride up over the other one . In this case , the Pacific Ocean goes under the continents and when that happens it seems to produce magma （熔岩）at depth and then you have volcanoes in the same ring .
1．What kind of writing do you think this passage is ?
A．A text taken from a geography book . B．An interview published in the press .
C．A conversation carried out in a film . D．An oral test recorded as an example .
2．Which of the following statements can correctly explain why we have so many volcanoes around the Pacific Ocean ?
A．The movement of the surface of the earth makes it possible.
B．The Pacific Ocean produces magma and presses it everywhere.
C．The oceans and the continents are separated from each other.
D．The earth’s surface around the Pacific is thinner than any other part.
3．Barbara Reynolds’ main purpose here is______________ .
A．to show how dangerous volcanoes are to the world
B．to learn what signs a volcano gives us before its eruption
C．to warn the world of the existence of “the ring of fire”
D．to introduce some general idea of volcanoes to the public
4．Which of the following can be considered as the best conclusion of the conversation?
A．There are so many volcanoes in the world and we are always in danger.
B．Volcanoes have erupted more frequently than ever before.
C．Volcanoes are waiting to be better known.
D．Something must be done to protect the people near the ring of fire.
