听力原文： The dog has often been an unselfish friend to man. It is always grateful to its master. It helps man in many ways. Certain breeds of dogs are used in criminal investigations. They are mined to sniff out drags and bombs. They help police to catch criminals.
The dogs that help in criminal investigations are trained at a school called the Military Dog Studies Branch of the U.S. Air Force in Lackland, Texas. The dogs to be trained are selected by an air force team. This team visits large cities across the country to buy the dogs. They may buy dogs from private citizens for up to $750 each. Some citizens freely give their dogs. The dogs selected must be healthy, brave and aggressive. They must be able to fight back if they are attacked. The dogs chosen are between the ages of one and three. They are given a medical examination when they arrive at the school. Their physical examination includes X-rays and heart tests. The trainee dogs undergo the first stage of training when they arrive in Lackland. This is an 11-week course for patrol duty. After this course, the best dogs are selected to go on another 9-week course. They learn drug-sniffing or bomb-sniffing. After this course, the dogs are ready for their jobs in the cities or on air force bases.
The training given to a drug-sniffing dog is different from that given to a bomb-sniffing dog. A drug-sniffing dog is trained to scratch and dig for the drags when he sniffs them. A bomb-sniffing dog sits down when he finds a bomb. That is the alert for hidden explosives.

Understanding the shape and size of the ionosphere is an important first step in figuring out how particularly dense regions within it may distort radio, radar and navigation signals. Such distortions can make communications and satellite-based systems less reliable.
"In order to predict how severe those distortions will be, it's necessary to know how big those structures in the ionosphere are and where they exist," Roderick Hellis, with the Space sciences Center at the University of Texas in Dallas, told Discovery News.
Hellis and his colleagues have been using a suite of NASA instruments called CINDI, which fly on the U.S. Air Force Communication/Navigation Outage Forecast System (C/NOFS) satellite between 250 miles and 530 miles around the planet's equator.
The researchers never expected to encounter the edge of Earth's ionosphere at those altitudes, but that is exactly what happened during the summer of 2008, a time when the solar activity was unusually weak.
"It was a real combination of low solar activity and the satellite's range," Hellis said. "We didn't expect to be able to look at the top of the ionosphere in all places." Computer models based on previous research had predicted the ionosphere to be about 370 miles above Earth at night and about 620 miles up during the day--the variation due to temperature and other factors.
Instead, the CINDI team discovered that the transition between the ionosphere and space was about 250 miles above Earth at night and about 500 miles up during the day.
The ionosphere is primarily caused by extreme ultraviolet energy from the sun.
"It's powerful enough that those photons (光子) can ionize (使……电离) atoms in Earth's upper atmosphere," said David Hathaway, a solar physicist at NASA's Marshall Space Flight Center in Huntsville, Ala. "When you have a geomagnetic disturbance or a solar flare going off, you can get an ionosphere that is uneven, which can cause problems with radio signals and GPS satellite signals, which have to pass through."
The findings were presented at the annual American Geophysical Union conference in San Francisco last month.
CINDI is an acronym for Coupled Ion Neutral Dynamics Investigation. The device works by separately measuring ionized and neutral particles at altitudes where the Air Force satellite flies. A similar device is on another polar-orbiting Air Force spacecraft.
The researchers hope to keep using CINDI as solar activity picks up in the sun's new 11-year cycle. The next solar maximum is expected in late 2011 or 2012.
We have always had a misconception about______.
A．how far away the upper edge of the ionosphere is
B．how many particles comprise the ionosphere
C．how long the ionosphere has been existing
D．how the ionosphere extends into space
