听力原文： American engineers Paul Flores and Jim Gibbson are studying Mexico's earthquake warning system. They hope such a system could be implemented in California where earthquakes are quite common even if it could give only a few seconds of warning before an earthquake.
"With just a couple of seconds' warning, teachers, for example, can get the children under the desks before things on the shelves start failing onto their heads, "Flores said, "That's what early warning could do in the States."
Flores and Gibbson have a one-year, $ 50,000grant from the National Science Foundation to study Mexico's early warning system. The system is made up of 12 earthquake monitors buried 305 kilometers south of Mexico City along the coast.
When an earthquake measuring 3.5 or greater on the Richter scale strikes, the monitors detect the shack waves and instantly send out an electronic signal to computers in Mexico City. The computers process the information and continue to pass it to radio stations and public speakers that sound earthquake alarms. City residents can then be warned to get to safe places. Since the electronic signal travels faster than the quake's shock waves, the city can receive a warning of about one minute before the quake strikes.
But a similar system in California would not be able to give that long a warning because earthquake centers are much closer to population centers.
Gibbson noted that problems do exist with Mexico's system, including false alarms issued by small earthquakes. "But people shouldn't lose confidence in the warning system," Gibbson said. And according to an earthquake expert in Mexico City, there are more benefits than problems. "We still have a lot to learn, but the more we learn, the better it will be for people in California to be able to use a system one day based on our actual experience," the expert said.
(35)
A．Because the state of California is much larger.
B．Because the electronic signal travels faster in Mexico.
C．Because the quake's shock waves are stronger in California.
D．Because quake centers are much closer to population centers in California.
Moderate earthquake strikes England
A moderate earthquake struck parts of southeast England on 28 April 2007，toppling chimneys from houses and rousing residents from their beds． Several thousand people were left without power in Kent County．One woman suffered minor head and neck injuries．
“It felt as if the whole house was being slid across like a fun—fair ride，”said the woman．
The British Geological Survey said the 4．3-magnitude quake struck at 8：19 a．m． and was centered under the English Channel，about 8．5 miles south of Dover and near the entrance to the Channel Tunnel．
Witnesses said cracks appeared in walls and chimneys collapsed across the county．Residents said the tremor had lasted for about 10 to 15 seconds．
“1 was lying in bed and it felt as if someone had just got up from bed next to me，”said Hendrick van Eck．27．of Canterbury about 60 miles southeast of London．“I then heard the sound of cracking，and it was getting heavier and heavier．It felt as if someone was at the end of my bed hopping up and down．”

Moderate Earthquake Strikes England
A moderate earthquake struck parts of southeast England on 28 April 2007, toppling chimneys from houses and rousing residents from their beds. Several thousand people were left without power in Kent County. One woman suffered minor head and neck injuries.
"It felt as if the whole house was being slid across like a fun-fair ride," said the woman.
The British Geological Survey said the 4.3-magnitude quake struck at 8:19 a.m. and was centered under the English Channel, about 8.5 miles south of Dover and near the entrance to the Channel Tunnel.
Witnesses said cracks appeared in walls and chimneys collapsed across the county. Residents said the tremor had lasted for about 10 to 15 seconds.
"I was lying in bed and it felt as if someone had just got up from bed next to me." Said Hendrick van Eck,27, of Canterbury about 60 miles southeast of London." I then heard the sound of cracking, and it was getting heavier and heavier. It felt as if someone was at the end of my bed hopping up and down."
There are thousands of moderate quakes on this scale around the world each year, but they are rare in Britain. The April 28 quake was the strongest in Britain since 2002 when a 4.8-magnitude quake struck the central England city of Birmingham.
The country&39;s strongest earthquake took place in the North Sea in 193 l, measuring 6.1 on the Richter scale. British Geological Survey scientist Roger Musson said the quake took place on 28 April in an area that had seen several of the biggest earthquakes ever to strike Britain, including one in 1580 that caused damage in London and was felt in France. Musson predicted that it was only a matter of time before another earthquake struck this part of England. However, people should not be scared too much by this prediction, Musson said, as the modern earthquake warning system of Britain should be able to detect a forthcoming quake and announce it several hours before it takes place. This would allow time for people to evacuate and reduce damage to the minimum.
