Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them,“Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered,“Your brother. Because electricity travaels faster than sound waves.”“That’s every good,”Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said.“Yes, Kate.”
“I disagree,”Kate said.“Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”

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.

This summer vacation,Xiaokai,a high school student in Guangzhou,planned to spend his time surfing the Internet,playing basketball and watching TV.
But Xiaokai's parents tried to make him read some classics at home.In their yees,reading the classics would do his son much more good than other activities.
Though his room was full of the classic books,he had just finished reading one of them,The Old Man and the Sea.
"I picked up the book just because it was not very thick,"he said."Nothing impressed me at all after reading."

It is the same with teachers.One middle school Chinese teacher once prepared a chart(图表) of Interpersonal relationship in the best-known novel Dream of Red Chamber for his students. They were asked to remember how the characters are related to each other while preparing for the final exam.
