A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami（海啸） warnings just three minutes later. The country has one of the best earthquake early warning systems in the world.
There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes.
There are also concrete(混凝土) sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami.
Costas Synolakis ，a tsunami expert at the University of Southern California in Los Angeles said，"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event."
He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan.
The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas.
Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves.
Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted

3.According to Costas Synolakis, why did Japan suffer such a loss?
A. The country has never experienced any event as big as this one over the past 150 years
B. Japan has the best earthquake early warning systems in the world.
C. There are not concrete sea walls around all of the Japanese coastline

Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion（混淆） over possible links to the country of the same name, but Sudan officials say there is no connection whatever．
Sudan 1 is a red industrial dye（颜料） that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003．
Since the ban was put in place, EU officials have been trying to remove some food products from the shelves．So far 580 products have been recalled．
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification(澄清) of the origin of the dye’s name．
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye．
"We want to keep an eye on every detail and avoid any misunderstanding there," she said．"Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country．But they told us there was no relationship．"
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week．
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said．"People found the dye in 1883 and gave it the name．Nobody knows the reason, and we cannot give any explanation before we find out．"
Sudan dyes, which include Sudan 1 to 4, are red dyesused for colouring oils, waxes, petrol, and shoe and floor polishes．They are classified as carcinogens by the International Agency for Research on Cancer．

At a primary school in a small town in the east of South Carolina, second-grade teachers Garneau and Lynne are convinced that separating elementary-age boys and girls produces immediate academic improvement in both genders（性别）．
David Chadwell, South Carolina’s expert of single gender education says, “Boys and girls learn, hear and respond to their surroundings differently．We can teach boys and girls based on what we now know．”
Male and female eyes are not organized in the same way, he explains．The organization of the male eye makes it sensitive to motion and direction．“Boys understand the world as objects moving through space,” he says．
The male eye is also drawn to cooler colors like silver and black．It’s no accident that boys tend to create pictures of moving objects instead of drawing the happy colorful family, like girls do in their class．
The female eye, on the other hand, is drawn to warmer colors like red, yellow and orange．To attract girls, Chadwell says, the teacher doesn’t need to move as much as in boy’s class．Using descriptive phrases and lots of colors in presentations or on the blackboard gets their attention．
Boys and girls also hear differently．“When someone speaks in a loud tone, girls understand it as yelling,” Chadwell says．“They think you’re mad and can shut down．” Girls are more sensitive to sounds．He advises girls’ teachers to watch the tone of their voices．Boys’ teachers should sound more forceful, even excited．
A boy’s nervous system causes him to be more cautious when he is standing, moving, and the room temperature is around 69 degrees Fahrenheit．Stress in boys, he says, tends to increase blood flow to their brains, a process that helps them stay focused．Girls are more focused when seated in a warmer room around 75 degrees Fahrenheit．Girls also respond to stress differently．When exposed to threat and conflict, blood goes to their guts（肠道）, leaving them feeling nervous or anxious．
These differences can be applied in the classroom, Chadwell adds．“Single gender programs are about making the best use of the learning．”
1.What is David Chadwell’s attitude toward separating elementary-age boys and girls while learning?
A．Supportive B．Worried C．Concerned D．Uninterested
2.To engage boy in a class, the teacher ______．
A．must have a moving object in this hand
B．needs to wear clothes in warm color
C．has to speak politely
D．had better move constantly while teaching
