Many animals move from one place to another at certain times of the year. This annual movement is called migration. They migrate to find food, seek a partner, or in search of warmer weather. One of the most wonderful migrations in nature is that of the North American monarch butterfly.
Every autumn, millions of these beautiful insects with fine black and orange wings begin a long and difficult journey. Somehow they manage to travel around 4, 000 kilometers south and find their way to California or Mexico. However, until recently no one knew how they did this.
A team of scientists led by Professor Eli Shlizerman at the University of Washington has now found the answer. They have found out that the monarch is able to tell the time of day. It uses its eyes to measure the position of the sun. These two pieces of information—the time of day and the point where the sun is in the sky—allow the butterfly to determine the way to go. Eventually, it manages to reach the places where it will spend the winter.
The solution to the mystery of the monarch’s amazing ability comes at a time when it is in serious trouble. Its population has crashed by as much as 90 per cent in the last few years. Sadly, human activity is the main reason why the number of monarch butterflies is falling. In many of the places where the butterfly can be found, people are destroying the natural environment. They cut down trees and use chemicals that kill the plants that monarch caterpillars eat.
The research on the monarch’s behavior has however led to a greater awareness of this creature. People have been working together to record its migration and make sure that there are enough plants for it to feed on. If this works, there may come a time when the number of monarch butterflies increases once again. The more we know about this lovely creature, the greater the chance it will survive and keep its place in the natural world for a long time to come.
1.Which is not the purpose of animals’ migration according to the text?
A.To search for food. B.To look for a partner.
C.To breed young babies. D.To stay away from cold weather.
2.What mainly caused the decrease in the number of the monarch butterflies?
A.Weather changes. B.Human activities.
C.Trees being cut down. D.The long migration every year.
3.What can we know from the text?
A.All the animals migrate at fixed times of the year.
B.The monarch has the ability to identify the time of day.
C.The population of the monarch is decreasing rapidly every year.
D.No one knows how the monarch butterflies make their way to their destinations.
4.What does the last paragraph imply about the research?
A.It is quite encouraging. B.it is fairly complex.
C.It is very unacceptable. D.It is rather useless.

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

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

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back.. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach..
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.
1.The holly plant has more spines on the lower leaves because most animals________.
A. are not tall enough B. like the lower leaves only
C. are not clever enough D. can get the lower leaves easily
2.To defend themselves, oak trees use________.
A. chemical means B. physical means
C. bitter chemicals D. sandy materials
3.How does tobacco protect itself against an attack from a caterpillar?
A. Its leaves fight against the attack by physical means.
B. Its roots send a messenger to discourage the caterpillar.
C. Its roots increase the production of nicotine when it is attacked.
D. Its leaves produce poisonous sand to drive the caterpillar away.
4.What would be the best title for this passage?
A. Plants and Animals B. How Plants Defend Themselves
C. Attacks and Defenses D. How Animals Eat Plant Leaves
