Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（迁徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening.
1.The passage is mainly about______.
A. how lemmings find food
B. why animals kill themselves
C. the lemmings’ self-killing
D. the food supply in the Scandinavian mountains
2.A reason for the lemmings’ self-killing might be that they______.
A. go mad from a lack of food
B. hope to find fish for food
C. decide to reduce the population
D. think they can cross the sea
3.Why are scientists curious about the lemmings’ behavior?
A. Because they are the only animals that live in Scandinavia.
B. Because it is very unusual for animals to kill themselves.
C. Because of the amount of food they can eat on their march to the sea.
D. Because they can gather together in such huge numbers.
4.The underlined word “singular” means______.
A. unusual B. single C. wonderful D. common

Who would have thought to put a kite and a surfboard together? It may seem like an impractical idea, but a man named Cory Roeseler from Oregon believed that it would work, and introduced the idea in the 1980s．1. Over the next few years, other designers contributed to the style and shape of the board, resulting in a mixture of kiting and surfing, which is what kite surfing is today．
2. The power kite pulls a small board that is fastened to the surfer’s feet, and there is a harness (安全带) that goes around the surfer’s waist to make sure that the surfer stays connected to the board．The wind determines which direction would be easiest for the surfer to go in．Once the kite surfer is able to control the board and the kite, they can learn many tricks, such as turning, jumping, and so on． 3.
This sport can sometimes be potentially dangerous to other kite surfers, beachgoers, and the kite surfers themselves if they don’t know how the proper procedure is done．4. They can learn the techniques safely without putting themselves and others in danger．A good course should include basic operations, kite set-up, maintenance (维修) of equipment, weather planning, and emergency landings．These courses are available in almost all areas where kite surfing is popular．
5. Some popular destinations for kite surfing enthusiasts are South America, Europe, Asia, Africa and Australia, but wherever there is wind, there will be kite surfers．You might even be able to see kite surfers on the beach closest you!
A．Kite surfing has become a mainstream sport．
B．Kite surfing is a difficult and dangerous sport．
C．The way it works is an application of simple physics．
D．The first design was with water skis powered by a kite．
E．It is also known as kite boarding, and in some European countries as fly surfing．
F．Therefore, it is highly recommended that people who want to participate in this sport attend a
course．
G．With the combination of the wind and the ocean, some kite surfers can go at top speeds while
flying over 20 feet in the air．

Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(树皮) of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
1.This passage mainly talks about ______.
A. the change of color in locusts
B. the protective coloration of animals and pests
C. how a certain sea fish protects itself
D. animals or pests can dye themselves different colors
2.Locusts are ______ but they aren’t easily wiped out(消灭)by their enemies because _______.
A. animals; they are powerful enough
B. beasts; they are dangerous to their enemies
C. pests; they take on the same colors as crops
D. birds; they fly very fast
3.What does the underlined word “invisible” in Paragraph 3 mean?
A. can’t be seen B. can be seen C. can’t move D. can’t change

Animals are being killed by hunters in America in a cruel way, says an animal protection organization. There are about 1,000 hunting farms across America whose owners offer hunters an opportunity to kill animals that are kept in fenced areas.
Russian boar, zebra, deer, antelope and many other species are raised just to be killed. Farm owners charge hunters thousands of dollars for animals that they kill, many of which are close to extinction (灭绝).
The Humane Society of the United States says this type of hunting should be stopped because it is not fair to the animals. Many owners raise their animals. Others buy from animal dealers or from zoos and circuses that no longer want them. This means that the animals are not afraid of humans and they are easy to be shot by hunters.
Owners of small ranches (牧场) keep their animals in fenced areas so that the hunters can get close to the animals before shooting at them. On large farms hunters are taken to areas where the animals are fed sometime of the day. This also makes it easy to kill the animals.
The hunters want to keep the heads and chests of the animals they kill to hang as trophies (战利品) on their walls. This means that the animals are usually shot in parts of the body. That means they will suffer a slow and painful death.
The hunting is allowed across most of America but some parts of the country have stopped or restricted it. The Humane Society of the United States hopes that it won’t be too long before the rest parts of the country also give up this cruel sport.
1.What can be the best title for the passage?
| A．Fenced Animals Are in Danger |
| B．Animals Are Easy to Kill |
| C．Hunters Pay to Kill Fenced Animals |
| D．Animal Hunting Should Be Banned |
2.One of the main reasons why these animals are easy to be shot is that _______.
| A．they don’t run very fast |
| B．they are not afraid of humans |
| C．they don’t know how to escape |
| D．the hunters are good at shooting |
3.What can we learn from the passage?
| A．Many animals can run away when hunters want to shoot them. |
| B．It is very cruel to kill the animals in the way mentioned in the passage. |
| C．The Humane Society of the United States considers this kind of hunting as a good sport. |
| D．The animals are usually hung on the walls after being shot. |
4.It can be inferred from the passage that _______.
| A．no measures have been taken to prevent this kind of hunting |
| B．the animals usually get really hungry before dying |
| C．in most parts of America this kind of hunting has been stopped |
| D．people who do this kind of hunting are probably very rich |
