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. 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 |
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 |
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. |
The underlined word “singular” means______.
| A.unusual | B.single | C.wonderful | D.common |
Endangered languages are languages that wouldn’t exist any longer, much like endangered species of plants or animals. Languages are considered to be endangered when parents are no longer teaching the language to their children and are not using it actively in everyday life. A language is considered to nearly disappear when it is spoken by only a few elderly native speakers.
The world faces enormous challenges in order to protect different kinds of languages. Of the more than 6,912 languages, half may be in danger of disappearing in the next several decades.
It is caused by many reasons: small numbers of speakers, the regular use of other languages, attitudes towards their languages, moving of the younger population, government policies, and languages used in education and so on. A language may lack important things such as a body of literature, and people who read and write it. A language may also lack prestige (声望) and support of its speakers.
The survival of a language is also threatened when speakers move to other areas where different languages are spoken, or when government policies improve the use of a specific language in school, official business and the media. These situations encourage people to learn the wider-known language and may cause them, especially the young, to stop using their mother tongue. Often those speaking lesser-known languages will choose to learn a more prestigious language with the hope of greater economic opportunities. Most of the world’s parents are teaching their children English, French, Spanish, Chinese, Arabic, Russian or some other main languages instead of their own languages for social and economic reasons.What’s the main idea of this passage?
| A.Languages in the world. |
| B.Reasons why languages become endangered. |
| C.What an endangered language is. |
| D.Languages spoken by few speakers. |
About ________languages will probably disappear in this century according to the passage.
| A.more than 6,912 | B.more than 3,456 | C.6,912 | D.less than 3,456 |
Which of the following best shows the structure of the passage?
①=Paragraph1 ②=Paragraph2 ③=Paragraph3 ④=Paragraph4
We can infer that the best way to maintain an endangered language is to _________.
| A.forbid the speakers to move about |
| B.pass laws to protect the language |
| C.raise the salaries of the people who speak the language |
| D.teach the language to young children and encourage people to speak it often |
All of the following about languages are true EXCEPT __________.
| A.many languages will be probably endangered in this century |
| B.government policies have a big effect on languages |
| C.the endangered language is a language that is spoken by a few people |
| D.languages are related to their speakers’ social and economic position |

The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.
The deserts of the world are not uninhabited (not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, pat them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people.
