"I thought I had planned for everything." These are the words of a flood victim—they could be yours.
Thousands of people every year find out that it CAN happen.
Are you prepared for a flood？ Did you know you don't have to live close to water to become a flood victim？ De you have flood insurance？
You need to know the answers to these questions, because the terrifying truth is that floods can happen anywhere, anytime.
Flood insurance is the best way to protect you before the flood hits. Flood damage often goes way beyond that of house and home. Flood victims not only lose their homes and treasured possessions, but rebuilding costs also eat up life savings, retirement funds and children's college education.
You can protect yourself-through the National Flood Insurance Program. We have one mission: to restore the quality of life of flood victims as soon as possible. For more information, call your insurance company, agent or 1-800-611-6122, ext. 24.
"I" in the title refers to【46】.
You should know the truth that flood can happen【47】.
The advertisement is directed towards【48】.
According to its introduction, any one can protect himself through【49】.
The mission of the company is to【50】.

panic
A panic is a form. of collective in which a group of people, face with an immediate threat, re- act in an uncoordinated and irrational way. Their behawor is uncoordinated in the sense that co- operative social relationships and break down. It is irrational in the sense that people&39;s actions are not appropriate for the goals they wish to achieve.
The progress of a panic follows a fairly typical course. A sudden crisis occurs ; people experi- ence intense fear; normal social expectations are broken; each individual tries desperately to es- cape from the source of danger; mutual cooperation breaks down; and the situation becomes even more threatening as a result. Panics are especially likely to occur in unusual conditions in which everyday norms have little relevance, such as fires, floods, earthquakes or military invasions.
Some kind of response is necessary in these situations, but there are few social norms that specify an appropriate reaction. Thus, when a passenger aircraft makes a crash landing people may at- tempt to flee before fire breaks out and cause an explosion, but there only succeed in stopping themselves and others by creating bottlenecks at the exits. Awareness of bottlenecks, may lead to increased panic, with people fighting and trampling one another in the effort to escape. Despite intensive training of airline personnel in emergency evacuation procedures, a high proportion of passenger deaths are caused by a panic that prevents people from escaping in time.
The most dramatic panics are those that occur in situations of extreme emergency, but not all panics are quite so frantic or short-lived. A different form. of this collective behavior. is the finan- cial panic, which is typically provoked by rumor that the price of stocks will fall or that a bank will be unable to repay its depositors. The classic example, of course, occurred at the outset of the Great Depression in 1929: as in other forms of panic, the individuals involved tried to protect their own interests, and in so doing they worsened the situation for themselves and everyone else. By trying to sell their stocks as quickly as possible, people ensured that the price of stocks did fall; by demanding their money back from banks, they ensured that the banks actually did collapse.
What will people not do when they feel panic？ 查看材料
A.They become uncoordinated
B.They become irrational
C.They face an immediate threat
D.They break down cooperative social relationships
Ancient Egypt Brought down by Famine
Even ancient Egypt's mighty pyramid (金字塔) builders were powerless in the face of the famine (饥荒)that helped bring down their civilization around 2180 B．C.. Now evidence collected from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today.
The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons (季风) southwards out of Ethiopia would have reduced these floods.
Declining rains in the Ethiopian highlands would have meant fewer plants to stabilize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment (沉积) from the White Nile.
Blue Nile mud has a different isotope (同位素) signature from that of the white Nile, so by analyzing isotope differences in mud deposited in the Nile Delta Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.
Krom reasons that during periods of drought, the amount of Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4500 to 4200 years ago, immediately came before the fall of the Egypt's old Kingdom.
The weakened waters would have been disaster for the Egyptians. " Changes that affect food supply don't have to be very large to have a ripple (波浪) effect in societies. " says Bill Ryan of the Lamont Doherty Earth Observatory in New York.
"Similar events today could be even more devastating," says team member Daniel Stanley, a scientist from the Smithsonian Institution in Washington D.C.. "Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. "
Why does the author mention "Egypt's mighty pyramid builders"？
A．Because they once worked miracles.
B．Because they were well-built.
C．Because they were actually very weak.
D．Because even they were unable to rescue their civilization.
