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.＜br＞

"It felt as if the whole house was being slid across like a fun-fair ride," said the woman.＜br＞

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.＜br＞

Witnesses said cracks appeared in walls and chimneys collapsed across the county. Residents said the tremor had lasted for about 10 to 15 seconds.＜br＞

"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."＜br＞

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.＜br＞

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.

根据以下材料，回答题

A New Drug for Losing Weight

Scientists have developed a slimming drug that successfully suppresses appetite and results in a dramatic loss of weight without any apparent ill effects. The drug interferes with appetite control and prevents the build-up of fatty tissue. More importantly， the drug appears to prevent a serious decline metabolic rate——causing tiredness and lethargy——which is typically associated with living on a starvation diet. S a result， mice taking the drug lost 45 percent more weight than mice fed the same amount of food， which compensate for the lack of food by becoming more sluggish.

The scientists， from the Johns Hopkins University in Baltimore， said that C75 is likely to produce a similar effect on humans because appetite control in the brain is thought to be based largely on the same chemical pathways as those in mice. "We are not claiming to have found the fabled weight-loss drug. What we have found， using C75， is a major path way in the brain that the body uses naturally in regulating appetite at least in mice，" said Francis Kuhajda， a pathologist and senior team member. "We badly need effective drugs for weight loss. Obesity is a huge problem.

We"re hoping to explore the possibilities of this new pathway，" he said.

Discovering a biochemical. Pathway in the brain that controls appetite raises new prospects for eloping slimming aids. Research on leptin， a hormone produced in fatty tissue for controlling fat deposits， has so far failed to produce the expected slimming drug break-through. The latest study， published in the journal Science， showed that even moderate doses of C75 produced a significant loss of appetite， which returned to normal after a few months.

The scientists believe that C75， which they produced synthetically in the laboratory， binds to an enzyme called fatty acid sythase， which is involved in storing excess food intake as fat.

Inhibiting enzyme causes a build-up of a chemical in the liver which acts as a precursor to fat deposition. This precursor is thought to have an indirect effect on the brain， causing appetite suppression.

Normally， when animals fast， a hormone called neuropeptide Y increases sharply in the appe-tite control centers of the brain， stimulating the desire for food. However， when animals are given C75， levels of this hormone fall， leading to a loss of interest in food. Dr Kuhajda said discovering that C75 has no effect on metabolic rate is one of the most significant findings of the study. "If you try to lose weight by starving， your metabolism slows down after a few days，" he said. "It"s a survival mechanism that sabotages many diets. We see this in fasting mice. Yet metabolic rate in the C75-treated mice doesn"t slow at all. "Further animals studies will be needed before C75 could be tested on humans.

Living on a starvation diet may result in __________. 查看材料

A.a dramatic loss of weight without any ill effects

B.a long-term loss of interest in eating

C.a slowdown of fat deposition

D.fatigue and inactivity
