Mammals. The Gerund
Activity 1
Read the given text and make your essential assignments:
A mammal is an animal that gives birth to live young and feeds them on milk. It is warm blooded, with specialised features distinguishing it from other animals, such as middle ear bones allowing good hearing and jaws with teeth to cut, chew or grind food, allowing most efficient digestion of nutrients and calories. Mammal embryos in the uterus are initially protected from rejection by the mother's immune system and subsequently nourished by a placenta, which means they can stay in the womb long enough to develop specialised features such as flippers or wings and are generally born fully formed. The mother-child bond is strong and young animals learn by copying adult behaviour.
The range of mammals is wide, including marsupials, rodents, predators, large plant eaters, aquatic mammals and primates. Each species' physiology is highly adapted to its environment and lifestyle. Mammals also have large brains and highly developed nervous systems, enabling more intelligence and resourcefulness than other animals, a key survival feature. Learned behavior is passed on from one generation to another, so younger generations benefit from their ancestors' experience. This was vital to human evolution and flexible adaptation and problem solving skills are still an exceptional feature of our species.

1. What is a mammal?
2. What kind of mammals do you know?
3. What is a mammal’s survival feature?
4. Do they have specialized features?

Activity 3
Say whether the following statements are true or false:
1. Mammal embryos in the uterus are not initially protected from rejection by the mother's immune system.
2.Flippers or wingsare generally born fully formed.
3.Mammals have not large brains and developed nervous systems.
4.Behavior is passed on from one generation to another.
5.The mother-child bond is strong and young animals learn by copying adult behavior.
