All animals—from humans to birds，worms and crocodiles—sleep，however，not all species sleep alike. Scientists have long puzzled over which aspects are truly fundamental. Now a new study on lizards(蜥蜴)suggests that sleep states once thought to occur only in mammals and birds have much older evolutionary origins.

Scientists had long doubted that birds and mammals are the only vertebrates(脊椎动物)to experience rapid eye movement(REM)，a sleep state in which the body is mostly immobile but the brain is overworking. During REM sleep，the brain produces high-frequency waves of electrical activity and the eyes turn suddenly from time to time. In humans，REM is closely linked to dreaming. REM is a pattern of slow-wave sleep，a state in which brain activity weakens and the waves become more consistent. This slower state is widely thought to be important to memory formation and storage.

“But scientists who looked for signs of REM and slow-wave sleep in reptiles(爬行动物) have had‘confusing’results，”says Gilles Laurent，a neuroscientist at the Max Planck Institute for Brain Research in Frankfurt，Germany. So he and his colleagues had planned to examine how the lizards—a common pet in Germany use visual information to chase treats. Using camera，the team found that the sleeping lizards’eyes twitched during the REM-like stage，just like other animals. They also found a very familiar pattern within the slower phase of the lizards’brain waves. Some scientists believe these waves help transform new information into memories by replaying past events quickly.

Although more studies are still needed to determine whether the function of these brain wave patterns is the same across species，the results suggest that these REM and slow-wave sleep patterns could date all the way back to the common ancestor of reptiles，birds，and mammals.

1.What does paragraph 2 mainly talk about?

A.The origin of human dream.

B.The definition and effect of REM.

C.The features and course of memory.

D.The advantages and disadvantages of REM.

2.Which of the following can best replace the underlined word“twitched”in paragraph 3 ?

A.opened wide B.moved quickly

C.stayed closed D.kept still

3.How does the lizards’brain waves turn information into memories according to some scienfists?

A.By increasing their frequency slowly.

B.By changing their pattern occasionally.

C.By playing back the past events quickly.

D.By connecting visual information effectively.

4.What can we infer from the last paragraph?

A.The function of the brain wave is the same.

B.All the animals have the common ancestor.

C.The sleep pattern of all the animals is the same.

D.The study about sleep pattern has a long way to go.

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.

When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移) is probably the migration of the fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

Recently, scientists have studied the migration of a kind of lobster(龙虾). Every year, when the season of bad weather arrives, the lobster get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.

So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like travel.

1.Most animals move from one place to another at a certain time to _____.

A. give birth　　 B. enjoy warmer weather

C. find food more easily　　 D. find beautiful places

2.The mice in northern Europe move when _____.

A. they need fresh water　　 B. the weather is bad

C. the place gets too crowded　　 D. they haven’t enough food

3.This passage is mainly about _____.

A. why animals move from one place to another　　 B. how animals can find food easily

C. new discoveries of animals traveling　　 D. some problems with traveling
