How can we reduce the risk?
There are four general approaches to dealing with volcanic 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 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 time 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.
1.The passage is intended for ________.
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. like to live near a quiet volcano
D. find a safer place far away from a volcano
3.The writer mentioned Nevado del Ruiz to prove ________.
A. The failure to keep volcanic dangers from happening
B. The importance of preparing for a volcanic eruption
C. The bravery of the people in Armero Town
D. The uncertainty of volcano’s damage

Humans are much worse at estimating risk than we think we are. While we overestimate the risk of rare but disastrous occurrences, such as being attacked by a shark, many of us seriously underestimate the risk of behaviors that reduce our lifespan (寿命), such as smoking.
In fact, there are two types of risks — acute and chronic. Acute risks are those that may kill you immediately, such as a car accident.
Chronic risks don’t kill you immediately but rob you of your life a little at a time. If you choose to eat an unhealthy diet, for instance, you may appear to be getting away with this, but you risk developing illnesses in future that may shorten your life.
The problem is we value things much less when they occur in the future. Distant events are abstract — we don’t know how and when they might affect us -~ so we care less about them.
Take smoking for example. It is just about the worst choice you can make for your health. Every two cigarettes that you smoke takes 30 minutes off your lifespan.
In contrast, eating vegetables is clearly very good for you, with each serve increasing your lifespan by two hours. This is a massive health gain and clearly should be a strong motivator for you to eat healthily.
Drinking coffee is also good for you, though with limited health gains. Each cup of coffee (assuming you drink reasonably), is associated with approximately a ten-minute gain in your lifespan.
Even drinking alcohol may add to your lifespan, with each serve adding 30 minutes to the length of your life. But this health gain is only true for the first drink; following drinks shorten lifespan. Alcohol also causes an acute risk when consumed in excess. Too much drinking gives you a 25 in one million chance of sudden death.
We shouldn’t be too nervous about exposure to risks. Life is all about making decisions about risks and rewards, and we all have a different starting point for what we consider acceptable risks to take. Even if we don’t always make the healthiest decisions, at least we can make ones that are fully informed.
1.Which of the following belongs to acute risks?
A. Eating junk food every day.
B. Being hit in a plane crash.
C. Staying up late every night.
D. Being too much overweight.
2.Why do people often ignore chronic risks?
A. They can often get away with them.
B. They can rid themselves of their side effects.
C. They don’t reduce their lifespan.
D. They will not cause immediate death.
3.Which habit will shorten your lifespan?
A. Eating vegetables every day.
B. Smoking only one cigarette a day.
C. Drinking a cup of coffee every day.
D. Drinking alcohol reasonably.
4.What does the underlined phrase “in excess” in the 8th paragraph mean?
A. At random.
B. In need.
C. More than enough.
D. Ahead of time.
