Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.
Farmers can also call on the services of their local hunt to control the fox population. Hunting consists of pursuing a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox they kill it or a hunter shoots it.
People who take part in hunting think of it as a sport; they wear a special uniform. of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.
It is estimated that up to 100,000 people watch or take part in fox hunting. But over the last couple of decades the number of people opposed to fox hunting, because they think it is brutal, has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of confrontation between hunters and hunt saboteurs. Sometimes these incidents lead to violence , but mostly saboteurs interfere with the hunt by misleading riders and disturbing the trail of the fox's smell, which the dogs follow.
Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Poster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.
Rich people in Britain have been hunting foxes______.

There is a growing feeling that science, especially what is known as the new physics, can provide answers where religion remains vague and faltering. Many people in search of a meaning to their lives are finding enlightenment in the revolutionary developments at the frontiers of science. Much to the bewilderment of professional scientists, quasi-religious cults are being formed around such unlikely topics as quantum physics, space-time relativity, black holes and the big hang.
How can physics, with its reputation for cold precision and objective materialism, pro- vide such fertile soil for the mystical？ The truth is that the spirit of scientific inquiry has undergone a remarkable transformation over the past 50 years. The twin revolutions of the theory of relativity, with its space-warps and timewarps, and the quantum theory, which reveals the shadowy and unsubstantial nature of atoms, have demolished the classical image of a clockwork universe slavishly unfolding along a predetermined pathway. Replacing this sterile mechanism is a world full of shifting indeterminism and subtle interactions which have no counterpart in daily experience.
To study the new physics is to embark on a journey of wonderment and paradox, to glimpse the universe in a novel perspective, in which subject and object, mind and matter, force and field, become intertwined. Even the creation of the universe itself has fallen within the province of scientific inquiry.
The new cosmology provides, for the first time, a consistent picture of how all physical structures, including space and time, came to exist out of nothing. We are moving towards an understanding in which matter, force, order and creation are unified into a single descriptive theme.
Many of us who work in fundamental physics are deeply impressed by the harmony and order which pervades the physical world. To me the laws of the universe, from quarks to quasars, dovetail together so felicitously that the impression there is something behind it all seems overwhelming. The laws of physics are so remarkably clever they can surely only be a manifestation of genius.
Scientists find the new cults bewildering because they are______.
Biologists have known for some time that giraffes solve this problem by having unusually high blood pressure, about double that of human beings. But an international team of biologists began to wonder about this. If giraffes have such high blood pressure, they should have a terrible problem with swelling in their legs and feet. Why don't giraffes have swollen feet？
Giraffes should have another problem, too. Every time they bend heads down to drink, the blood should rush to their heads and have a hard time flowing back up (when the head is down)to the heart. How come giraffes don't black out when they drink？
The answer to the swollen feet problem, the researchers found, is that giraffes have what the researchers call a "natural anti-gravity suit". It turns out that the skin and other tissues in their legs and feet are much stiffer and tougher than those of other animals. As a result, the blood vessels in the leg cannot swell. Therefore, the blood has nowhere to go but back to the heart.
What about blood rushing to the head whenever the giraffe bends down to drink？ The researchers found that the giraffe's jugular vein, which carries blood from the head back to the heart, has lots of one-way valves in it. In the giraffe's neck, there are lots of muscles that flex and relax repeatedly as the animal moves its head and sucks up drinking water. By squeezing the valved jugular vein, they keep blood moving back to the heart even while the animal is drinking.
Giraffes do not have swollen legs because______.
