A new paper published in Environmental Research Letters has some warning news for people living in the lower 48 states: You may be at risk from river flooding and not even know it until the water starts to rise.
In fact, the study, estimates of present and future flood risk in the United States, found that 41 million U. S. residents are at risk from flooding along rivers. That’s three times more than current estimates based on the flood maps produced by the Federal Emergency Management Agency (FEMA) , which primarily maps the areas at risk for 1-in-100-year floods in populous (人口众多的) river basins.
Why does the big difference come into being? As always, it’s all about the data. Generally, FEMA prioritizes risk-assessment areas based on their population; reserving expensive field-work methodologies (研究方法) for the more populous river basins, but many other rivers have not yet been mapped at all.
The size of the USA means that flood maps made in this way are incomplete. It would be too expensive and time-consuming to survey every river basin in America. The national-scale flood maps produced by FEMA leave the flood risk of many parts of the country unaccounted for.
For this research, scientists from The Nature Conservancy adopted a pioneering methodology that avoids the defects of the FEMA approach, where individual catchments (流域) are studied by making use of big data. The study used a new high-resolution model, produced by the flood-mapping organization Fathom, which copies floods on all rivers across the entire continental United States.
“We were all surprised by how many people are actually exposed to freshwater flooding in the USA,” said Oliver Wing, lead researcher on the study and a PhD student at the University of Bristol. “It’s particularly worrisome considering that most of these people aren’t even aware of the risk they face. This study helps fill that critical information gap.”

You may not pay much attention to your daily elevator ride. Many of us use a lift several times during a day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes an interesting social space where etiquette (礼仪) is sort of strange,” Gray told the BBC. “They are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift-users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want — it’s your own little box. If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
Newcomers to the lift will need to size up the situation when the doors slide open and then act quickly. Once in, for most people the rule is simple — look down, or look at your phone.
Why are we so awkward in lifts? “You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people, we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be considered to be threatening or strange, “The easiest way do this is avoid eye contact,” she said.
1.What is people’s response to the lift etiquette according to Gray?
A.Thinking much of it. B.Avoiding it on purpose.
C.Researching it continuously. D.Ignoring it unconsciously.
2.What does Gray think of riding a lift?
A.It’s funny and quick. B.It’s strange and dangerous.
C.It’s interesting but awkward. D.It’s convenient but boring.
3.What may most people do if they stay in the lift?
A.Talk loudly to each other. B.Keep still and silence.
C.Use mobile phones. D.Keep a close distance.
4.What’s the author’s purpose in writing the text?
A.To show how to ride each elevators.
B.To introduce some rules of elevator etiquette.
C.To show how to break awkwardness of riding lifts，
D.To analyze the reasons for keeping elevator etiquette.
I enjoy life because I am endlessly interested in people and their growth. My interest leads me to widen my knowledge of people, and this in turn makes me believe in the common goodness of mankind. I believe that the normal human heart is good since their birth. That is, it’s born sensitive and feeling eager to be approved and to approve, hungry for simple happiness and the chance to live.
Like Confucius, I am absorbed in the wonder of the earth, and the life on it. With a great faith in the human heart and its power to grow toward the light, I find here are reasons enough for hope and confidence in the future of mankind. The common sense of people will surely prove that mutual (相互的) support and cooperation are only sensible for the security and happiness of all. Such faith keeps me continually ready to do what one person can toward shaping the environment in which the human being can grow with freedom. This environment, I believe, is based upon the necessity for security and friendship.
I take heart in a promising fact that the future world will contain food supplies enough for the entire earth population. Our knowledge of medical science will be sufficient to improve the health of the whole human race. Our resources and education, if administered on a world scale, will lift the intelligence of the race.
Half a century ago, few people thought of world food, health and education. Many are thinking today of these things. Now I find my only questions about this: Are there enough people now who believe? Is there enough time left for the wise to act? It is a contest between ignorance and death, or wisdom and life. My faith in humanity stands firm.
