听力原文： Recently completed research reveals warmer oceans caused by global warming is making it more difficult for fish to breathe and survive.

Biologists have known for years declining fish stocks arc connected to global warming, but a new study of eelpouts—big-headed fish that resemble eels—is the first to go deeper and see how warmer seas are connected to how fishes take in oxygen.

Scientists studied the relationship between sea temperature and eelpouts counts in the Southern North Sea, combining data from the field with lab investigations of eelpout physiology.

The researchers not only found the oxygen levels in the waters of the North and Baltic Seas have dropped because of increasing temperatures over the past 50 years--a factor that reduces fish population— they also discovered eelpouts need more oxygen in warmer waters, a second factor that is reducing their numbers.

A key factor in the diminishing size offish stock is increased difficulty in absorbing oxygen via respiration and blood circulation caused by the warming waters.

Animals tolerate a limited range of environmental conditions. Anything out of their tolerance can cause damage. Fish in the North Sea have evolved to tolerate a wider range of temperatures than fish elsewhere because of the large seasonal fluctuations there.

Worldwide, warming waters can be expected to strain species that require lots of oxygen, forcing them to either relocate to cooler waters or face extinction.

B．Biologists have known for years declining fish stocks are connected to global warming.

C．Global warming has caused the seawater warmer.

听力原文： The slow stretches and meditations of yoga don't bum calories like a nm on the field. But a new study suggests it might help people keep weight off in middle age.

Researchers found that overweight people in their 50s who regularly practiced yoga lost about five pounds over 10 years, while a group in the same age range gained about 13.5 pounds over the same period.

The link between yoga and weight loss has nothing to do with burning calories. Except for very vigorous yoga practices, you don't really burn enough energy to make any difference in terms of weight. Instead, yoga helps keep people more in tune with their bodies and eating habits and aware of bad habits, such as eating because of stress, boredom or depression.

The researchers collected data from 15,500 people between the ages of 53 and 57 who were asked about exercise, weight, health and diet histories. The findings showed that those who practiced yoga tended to avoid junk food and overeating because they wanted to respect their bodies.

Some yoga trainers said it's difficult to eat heavily and do yoga. Doing certain movements does not work with a slice of pizza.

Scientists called the research encouraging, but said it's difficult to prove a direct influence from a single study.

Most yoga fans say weight loss is just an added bonus from the disciplined form. of meditation,controlled breathing and prescribed postures.

听力原文： Everyone knows about the Royal Canadian Mounted Police, but (29) nowadays the romantic red uniform. jacket is only worn on special occasions, and the famous horses are rarely seen. So the "Mountie", as a member of this police force is known, is not, in fact, often mounted except on a powerful motor-cycle. (30)He is a member of a very modern and efficient organization.

(30)A mountie may work in the Headquarters building in Ottawa. He may pilot a patrol plane across the snow-deserts in the north. He may be doing customs work at the frontier. He may be in plain clothes watching for s suspicious character at an airport, or he may simply be driving a patrol-car.

There are more than ten thousand men in this force, and it was one of these who was responsible for the arrest of James Earl Ray. Police all over the world were looking for Ray after the murder of Martin Luther King. In June 1968, a group of policemen in Canada were doing routine work with applications for passports. Suddenly one man noticed a photo which looked very much like Ray. The name was different, but the resemblance was so strong that (31) the police started to investigate. They discovered that the man had already gone to Britain. The photograph and the finger-prints were sent to the British police, who arrested Ray at London Airport, when he was just going to get on a plane for Brussels. The murder that had shocked the world was solved by a mountie on Ottawa.
