Sailing Through History
A group of 1,309 passengers boarded the MS Balmoral on Sunday, in Southampton, England, on a voyage to retrace the path of the Titanic. The Titanic was the biggest ship in the world when it sailed on its ill-fated maiden voyage in 1912. Of the 2,227 passengers and crew aboard, more than 1,500 died. The ship, which was headed to New York City, carried the rich and famous on its first voyage. It also carried immigrants, who were seeking a better life in America.
Relatives of people who sailed on the Titanic, historians, authors and people fascinated by the story of the unsinkable ship, are on the Balmoral. They want to remember the doomed ship and those who died on her first and last voyage. The historic liner had set sail on April 10, 1912, from Southampton. Late at night on April 14, she hit an iceberg. In the early morning hours of April 15, the Titanic sank.
The Balmoral is following Titanic’s original route from Southampton. First, the modern-day cruise liner docked in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stops in Cobh, Ireland, the Titanic’s last port of call before sailing to New York.
Balmoral will then cruise the North Atlantic Ocean to the location where Titanic hit an iceberg that ripped the ship’s hull(外壳). On Sunday, April 15, at 2:20 a.m.—the time the Titanic went down—passengers and crew will hold a memorial service. The next two days will be spent in Halifax, Canada, where many victims of the sinking are buried. Then, the Balmoral will reach its final destination in New York City, where Titanic was supposed to dock—but never did.
Until today, several teams of divers have explored the site. They have recovered some items such as dishes and silverware and put them on public display. And more trips are planned to the wreckage in the future. The Titanic and its passengers and crew have been remembered in books, movies and TV programs. But there’s a much more important contribution that Titanic gave us. After she sank, lawmakers and shipbuilders made ships safer. It took a terrible tragedy to make ship travel safer for all.

A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."
A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon.
　 What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all.
　　From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons (架线塔).
　　Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear (齿轮) is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered (改变) and can not be fully trusted.
　　These crash photos and videos shown here clearly have been doctored (篡改) and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma.
【小题1】Where can you possibly read this article?

【小题2】What the word “yielded” mean in the first sentence?

【小题3】Which of the following doubtful points is not mentioned in the passage?

A．the colors of the smoke	B．the model of the plane
C．the standing pylons	D．the marker line on the grass

【小题4】What is the author’s attitude towards the 911 investigation?

Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.

But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.

Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.

“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”
