How can we reduce the risk?

There are four general approaches to dealing with volcanic(火山似的)dangers.We can try to keep the danger from occurring—often an impossible task.We can try to change its path or reduce its impact on existing development. We can take steps to protect future development.We can also do our best to have disaster response plans in place before they are needed.

Removing the Threat

Clearly,there is no way to stop an eruption.We can,however,attempt to reduce the eruption’s effects by strengthening structures,for example,building protective works such as walls to make lava(熔岩)flow away from developed areas.Such efforts can be and have been successful,but are of limited use in a large-scale(范围)eruption.

Planning for the Future

Protecting future development from volcanic dangers is a simple task.Before building houses,we should judge the risk.If the risk seems too great,a safer location should be found.This type of planning is very effective,but all too often,people are drawn to the lush(葱郁的),rolling land of a quiet volcano.

Disaster Preparedness(预案)

When a volcano comes to life,a few weeks may not be enough to avoid a tragedy.Planning is the key to saving lives.Well before the warning signs occur,people must be educated about volcanic dangers.Escape plans must be in place.Communication between scientists,officials,the media,and the general public should be practiced.Emergency measures must be thought out and agreed upon.

If you doubt the importance of these efforts,take another look at past volcanic tragedies,such as the eruption of Nevado del Ruiz.Communication failures left the town of Armero unprepared for escape.When a deadly mudflow came down the slope(斜坡),21,000 people—90 percent of the town’s people—died.

A. the general public B. architects

C. adventurers D. geographers

2.When building houses,people tend to______.

A. judge volcanic dangers carefully

B. take volcanic dangers seriously

C. live near a quiet volcano

Background music may seem harmless, but it can have a powerful effect on those who hear it. Recorded background music first found its way into factories, shops and restaurants in the US. But it soon spread to other parts of the world. Now it is becoming increasingly difficult to go shopping or eat a meal without listening to music.

To begin with, “muzak” (音乐广播网) was intended simply to create a soothing (安慰) atmosphere. Recently, however,it has become big business—thanks in part to recent research. Dr. Ronald Milliman, an American marketing expert,has shown that music can boost sales or increase factory production by as much as a third.

However, it has to be light music. A fast one has no effect at all on sales. Slow music can increase receipts by 38%. This is probably because shoppers slow down and have more opportunity to spot items they like to buy. Yet, slow music isn't always the answer. Dr. Milliman found, for example, that in restaurants slow music meant customers took longer to eat their meals, which reduced overall sales. So restaurant owners might be well advised to play uptempo_music to keep the customers moving—unless of course, the resulting indigestion (消化不良) leads to complaints!
