Natural disasters such as earthquakes, tsunamis, and floods can often come at the least expected time．Others, such as hurricanes are increasing in severity and destruction．Typically, those poor countries are the worst hit for they have the least resources to deal with the destruction and rebuild their home．This part of the globalissues．org website looks at some of these issues．

Japan Earthquake, Tsunami and Nuclear Crisis

The earthquake off the coast of Japan on March 11, 2011 was one of the biggest recorded, measuring 9 on the Richter scale（里氏震级）．

It was the resulting tsunami, however, that caused the most destruction．It devastated the northeast of Japan, leaving many thousands dead or missing, and -hundreds of thousands homeless or leaving the area．In addition, various power generators（发电机组） failed．Some older nuclear power stations risked meltdown and suffered explosions and radioactive leaks．Workers battled for weeks to try and bring the situation under control．Radioactive material was detected in various places．

It is thought that the cost of the earthquake and tsunami could be over $ 300 billion-the world's most expensive natural disaster on record．

Hurricane Katrina

Hurricane Katrina was a destroyed category 4（四级） hurricane, the highest category, that hit the Gulf of Mexico and various Southern regions of the United States at the end of August, 2005, causing the worst damage in that country's history, estimated at $ 100 billion．The famous New Orleans city and surrounding areas were worst hit as much of it sits some 6 feet below sea level．City defenses, such as banks, only designed for categary 3 type hurricanes, gave way, leading to enormous flooding and associated damage, death and displacement of around 100, 000 people who either chose to say the course, or could not afford to flee．

I HEAR America beeping(嘟嘟响)．

Beep，says my cellophane when it gets a text message．

Beep，says my microwave oven when my sandwich is warmed up．

Sometimes I long for a natural sound：a bird singing，dog barking，children laughing， anything to drown out the maddening beeps that have become the soundtrack(配乐)to modern life．

My cellophane? It isn’t enough that its ring tone offerings seem to stretch from “annoymg” toextremely “annoying”． It also has to beep whenever someone texts messages me．

The microwave? A bell rings when it's finished heating my food．But is that enough? No．If I don’t rush to it right away, it starts beeping，like an impatient child tugging(用力拉) at my sleeve(袖子)．

The smoke detector(探测器) is the worst offender．When its batteries are in need of replacement，it 1ets out a series of chirps．The things that don’t beep buzz(嗡嗡响)．And for some reason，beeping and buzzing is beneath them，they clear their throats and perform a symphony． Like my TV, each time I turn it on, it performs an aria(咏叹调)：La di da di dum．Salutions! Here I am! Same thing when I turn it off: La di da di dum．Good bye, kind sir! Until the next time

But at 1east I know where each of these sounds is coming from．That isn’t always the case．For weeks, my wife and I were awoken in the night by a beeping．There，in the stillness， we went through the possible suspects．Could we have a text message? Could it be any of the devices(装置)able to make a sound? Curling iron, rice cooker, smoke detector, TV set，clock radio．．．

The only way to tell was to chase the sound down ，but no sooner would we pull on our bathrobes than the beeping would stop. We didn’t hear it every night but often enough that we would climb into bed wondering whether our sleep would be interrupted by that maddening sound，that beep．

Finally,early one morning，my wife found it：in the study,under a desk，a big plastic cube that was plugged into the wall．It was an uninterruptible power supply that we’d inherited(继承)from my wife’s mother．We’d never known it was capable of speech．

I think it just wanted someone to talk to.

14．What does the writer truly mean by saying“I hear America beeping”?

A．American people like devices that beep．

B．Americans are crazy about sending text messages．

C．In modern society people are dependant on technology．

D．The soundtrack to modern life is no longer natural．

15．Why couldn’t the author and his wife find the source of the noise in their house in the beginning?

A．There were too many devices for them to check．

B．They were unwilling to get up at midnight．

C．They had never known that thing could beep too．

D．The noise didn’t come every day．

16．After reading this passage，we can probably tell the author ．

A．enjoys being surrounded by beeps B．has a touch of humor in his writing

C．tries to avoid using anything that beeps

D．understands the beeping is designed to be user-friendly

US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado.
“This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.
“The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”
Analysis of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta (三角洲).
“Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.
Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.
The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
【小题1】The size of the lake found on Mars is ______.

A．80 square miles	B．1,500 square miles
C．3.4 billion square miles	D．300 million square miles

B．Because someone has put secrets about past life on Mars there.

C．Because past life has been found in other deltas on Mars.

D．Because some people are said to have already seen life marks there.
