1四、根据短文内容,从短文后所给的选项中选出能填入空白处的最佳选项。选项
中有两项为多余选项
When we look at animals, we know that they are not humans. But how do our closest
friends—dogs see us? 1. Or do they think that we are just different-looking dogs?
2. For example, the cuckoo (布谷鸟) will lay (产) its eggs in the nest (鸟巢) of
another kind of birds. The other birds will feed the baby cuckoos, even though (即使) they
look nothing like their babies. This is because feeding little ones is quite natural(自然的) for
birds.
Other animals may just divide(划分) the world into animals they eat and animals that eat
them. 3.
Sheepdogs leave their mothers when they are born. They grow up with sheep, and come
to see them as their family. For this reason, they never attack(攻击) the sheep. 4.
They probably think the sheep are dogs too, but we can’t be certain.
Similarly(类似地), if you raise(饲养) a dog from birth, the way it sees the world will be
different from a dog that grows up with other dogs. It may think it is the same kind of animal
as you. 5. A Russian boy was raised by dogs for two years and came to believe that
he was a dog himself.
A.You may be surprised to learn that many kinds of animals do not care such differences
very much at all.
B.When it comes to dogs, though, there is no simple answer to this question.
C.This can even be true of humans.
D.Do they know that we are humans?
E.Instead, they help protect them.
F.Dogs can give humans a lot of help.
G.Birds are different from other animals.

五、阅读理解
Almost all animals need to sleep to stay healthy. But sleeping can be dangerous because
other animals may hunt sleeping animals. To help them stay safe, animals have many
different ways of sleeping. Some of these ways may surprise you!
Some seabirds can sleep while they fly. These large birds spend most of their lives over
the ocean. They are in danger on the water, but they are safe in the air. They glide (滑行) for
many hours without moving their wings up and down. Sometimes they sleep while they glide.
2A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to
watch for danger. Dolphins can swim without sleep for two months to stay safe. Ducks sleep
with just half their brains too. These ducks often sleep in a line. The ducks at both ends help
keep the group safe. They keep one eye open to watch for danger. The ducks in the middle
sleep with both eyes closed.
Seals breathe air, but that doesn’t stop them from sleeping underwater. They hold their
breath and dive deep to sleep for up to twenty minutes at a time. Some fish make their own
sleeping bags. They make a big bubble and sleep inside it. It also keeps other animals from
smelling them. If an animal hits the bubble, the fish swims away quickly.
1.Why do animals have different ways of sleeping?
A.To hunt other animals. B.To make themselves safe.
