(A)

Around the world more people are taking part in dangerous sports and activities. Now, there are people who look for an immediate excitement from a risky activity which may only last a few minutes or even seconds.

I would consider bungee jumping (蹦极) to be a good example of such an activity. You jump from a high place 200 meters above the ground with an elastic (弹性的) rope tied to your feet. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is said that about 2 million people around the world have now tried bungee jumping. Other activities which most people would say are as risky as bungee jumping include jumping from tall buildings and diving into the sea from the top of high cliffs.

Why do people take part in such activities as these Some psychologists suggest that it is because life in modem societies has become safe and boring. Not very 10ng ago, people’s lives were constantly in danger. They had to go out and hunt for food, diseases could not easily be cured, and life was a continuous battle for survival.

Nowadays, according to many people, life offers little excitement. They live and work in quite safe conditions: they buy food in shops, and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to look for danger in activities such as bungee jumping.

The writer of the passage has a () attitude towards dangerous sports.

A. positive

B. negative

C. neutral

D. critical
