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

"Super Dan", as top-seeded Lin Dan of China is better known in the badminton（羽毛球） world, had his Olympic dream come true after claiming the men's singles gold by beating Lee Chong Wei of Malaysia on August 17 in the Beijing Olympics.

His father, Lin Jianbin, said "Super Dan"has waited for four years to get this championship and he felt very proud of his son, as well as his prospective daughter-in-law Xie Xingfang, who is also a badminton player and won silver in women's singles at the Beijing Games.

An SMS: The beginning of a love story

Lin was born in Shanghang County, Longyan in Fujian Province. He first met Xie Xingfang when he was 14-years-old. 16-year-old Xie was attending a national youth team badminton training camp in Jinjiang, Fujian and Lin was also there.

Tall and beautiful, Xie became the Snow White in the heart of Lin Dan, and he tried to please her and get chances to chat with her after the training sessions. He did not go beyond that.

Before the Spring Festival in 2004, Lin finally mustered（召集，聚集） the courage and sent Xie Xingfang a text message - I LOVE YOU. In fact, Xie Xingfang had already realized Lin Dan was fond of her. And covertly（秘密地） , she began to pay attention to Lin's movement and performance on the court. "He is very interesting, got a lot of ideas, and is a lovely boy."

Two Kisses

In May 2004 at the Thomas Cup in Jakarta, their love relationship was first known to the public. Xie sat with her teammates and watched the men's team playing. When Lin Dan won the match, he rushed to the bench and kissed Xie, a move that Xie did not expect Lin to do in public. A photographer captured this moment.

At the All England Open in 2007, Lin kissed her again in public, making Xie feel like the happiest woman in the world.

After Lin won his third title at the Open, he did not stay to watch Xie play. Xie defeated her opponent and won the championship. When she was called to accept the trophy（奖品，战利品） , Lin suddenly emerged at the central venue, holding red roses and gave her the flowers, and a passionate kiss.

Nine Roses

Earlier, on February 14, 2006, Lin and Xie were with the national badminton teams at a training camp in Jinjiang. The teams had their rules – not going out of the training camp. Xie thought she would spend the Valentine's Day without flowers.

But Lin still managed to give her a surprise – giving her a Dior wallet as a Valentine's gift and nine roses. With the teams' rule in place, Lin asked his local friend to buy the roses and gave her a pleasant Valentines surprise.

A 200-square-meter apartment

Lin Dan and Xie Xingfang's love has been through four years of tests, and Xie's father also said that they should consider marriage after the Olympics.

In fact, Lin Dan has already prepared for this. He has bought a 200-square-meter apartment in downtown Beijing, with 4 rooms and 2 living rooms. Paying about 20,000 yuan per square meter for the apartment, it is reported the apartment is now valued at 8 million yuan.

"After the Olympics, we really want to live our own lives, go on vacation, go to school, get married, I am really looking forward to it," Xie said happily.

With two kitchens, one Chinese and one Western style, Xie said she wanted to be the person preparing soup at home and enjoy family life.

In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.
In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them. "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning."
"What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."
"A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."
"You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."
Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.
【小题1】The one who first suggested the correct cause of the baby's illness was _____.
