The space shuttle Columbia flared and broke up in the skies over Texas on Saturday, February 1,2003, killing the seven astronauts on board in what NASA and President Bush called a tragedy for the entire nation. NASA launched an investigation into the disaster and began searching for the astronauts' remains. It said that although there had been some data failures it was too early to nail down a precise cause. The break-up, 16 minutes before the shuttle was due to land at Kennedy Space Center in Florida, spread possibly toxic debris(有毒的残骸) over a wide swath of Texas and neighboring states.
Dramatic television images of the shuttle's descent clearly showed several white trails(痕迹) streaking through blue skies after the shuttle suddenly fell apart. It was almost 17 years to the day that the Challenger shuttle exploded on Jan. 28, 1986, killing all seven astronauts on board.
Take-off and re-entry into Earth's atmosphere are the most dangerous parts of a space mission. In 42 years of US' human space flight, there had never been an accident in the descent to Earth or landing. Challenger exploded just after take-off.
Rescue teams scrambled to search for the remains of the crew, which included the first Israeli to fly on the shuttle, former combat pilot Col. Ilan Ramon. There were warnings that parts of a vast 120-mile-long corridor of debris could be toxic because of poisonous rocket propellant(推进器).
"We are not ready to confirm that we have found any human remains," Nacogdoches County Sheriff Thomas Kerrs said. He added that among the roughly 1,000 calls reporting debris, some people said they found remains of crew members.
"The Columbia is lost. There are no survivors, …Their mission was almost complete and we lost them so close to home. … America's space program will go on," said a grim-faced Bush in a message broadcast on television, which included condolences to the families of the dead astronauts.

3. The Columbia disaster and the Challenger disaster were similar in that ________.
A. there were seven astronauts killed on board
B. both the shuttles exploded when they took off
C. Both the shuttles exploded when they were about to land
D. no human remains were found
4. Which of the following is wrong according to the news?
A. The U.S.A. will give up the space program because of the accident.

The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状).

3. Arctic explorers may catch colds when _______.
A. they are working in the isolated arctic region
B. they are writing reports in terribly cold weather
C. they are free from work in the isolated arctic regions
D. they are coming into touch again with the outside world

At least 77 were wounded when hundreds of army soldiers and anti-government protesters (抗议者) clashed（冲突）in Bangkok early Monday morning, 14 hours after Thai PM (总理) declared a state of emergency in the capital city, Thai media reports.
The Nation quoted（引用）hospital reports as saying at least 77 people suffered injuries mainly from teargas, with five seriously injured.
At around 7:20 a.m., the government announced it was in control of the situation at Din Daeng, The Nation said on its website.
Some protesters had been arrested, and Army Spokesman Col Sansern Kaewkamnerd earlier said “Similar operations will be carried out in other areas.”
The clash occurred around 4:30 a.m. Monday (21:00 GMT Sunday) when some 300 so-called red-shirted protesters used a seized bus to crash soldiers at Din Daeng District in north Bangkok, Army spokesman Sansern Kaewkamnerd told TPBS.
Soldiers fired warning shots into the air and used teargas to disperse the protesters after failing to persuade the red shirts to stop, Sansern said.
Earlier the Health Department of Bangkok Metropolitan Administration announced a total injury number of 68.
Army Chief General Anupong Paojinda refused to comment on the incident, adding that he will learn more about it first.
At about 6:15 a.m. Monday (23:15 GMT Sunday), former premier Thaksin Shinawatra told the Red-shirted protesters to continue fighting in a phone conversation with a main leader of the United Front for Democracy against Dictatorship (UDD).
Thai Prime Minister Abhisit Vejjajiva declared on Sunday afternoon a state of emergency in Bangkok and some districts of five provinces nearby.
The latest round of the anti-government protests led by UDD has entered its 19th day. Red-shirted protesters on Saturday forced the summits canceled (取消).
