【简答题】
We tend to think of humans as the only creatures with organized societies in which each individual has or may have a particular role. However, there are other creatures, for example, insects such as ants, that like us, have complex societies. Ants are particularly interesting as they can be found in almost every part of the planet apart from Anarctica. The key to their success as a species is their social organization. Like humans, ants have division of labour. They live in colonies that range from about twenty five to millions of individuals. Each ant colony has one or more queens whose job is to lay eggs. These eggs are looked after by worker ants, which also perform other tasks such as searching for food, and building and defending nests. So clean and tidy are ants that some worker ants even have the task of taking rubbish from the nest. Ants have some fascinating physical features. They have two compound eyes-----each eye is made of many smaller eyes which increases how far they can see----and two stomachs, one of which holds the food for the ant, and a second which holds food to be shared with other ants. They can run extremely fast and are able to lift twenty times their own bodyweight, which is why one may see an ant carrying a piece of food many times its size. Ants use chemicals called pheromones to communicate with each other and leave pheromone trails to guide other ants to food. There are over 10,000 species of ants. Among them are slave-maker ants that steal ant eggs from other colonies, and when these hatch, make the new ants work as slaves. Leaf-cutter ants cut and take back pieces of leaves to their nests, then grow a fungus on these leaves that is used as food. Army ants are always on the move and carry their eggs with them. Perhaps now, after learning a little about these fascinating creatures, when you next look at an ant, you will see it with different eyes. 1、The passage says that ants are similar to human beings because _____. A. each ant has many roles B. they exist in every part of the planet C. they are very successful D. they have societies which are organized
