Man’s relationship with animals has always been ambivalent. On the one hand, animals have been w______d (1) and attributed all kinds of m______s (2) and superior powers. On the other hand, they have been h______d (3), domesticated, and even exploited as a source of entertainment. In many countries, man has also created i______y (4) creatures that play a major role in popular cultures. Ever since the dawn of civilization, animals have been used to help and to serve man in many ways. Sheep and goats were b______d (5) to provide wool, meat, and fat. Large animals like oxen, water buffalo and horses were used to p______l (6 ) plough and carry heavy loads. Capable of sensing water from a great distance and going days without water, camels proved to be the i______l (7) animal for the nomadic people of the desert. The dog, known in English-speaking countries as “man’s best friend”, is one of the most versatile animals. Dogs have been bred to hunt, to guard, to h______d (8) sheep and cattle, to find people in the snow or in the rubble of earthquakes, to lead the blind, and to sniff for i______l (9) drugs. However, sometimes animals can be very a______e (10) and they attacked or even killed people.
