    A computer program that could help catch and ever translates from aliens in outer space has been started by a British scientist.

    If aliens are discovered one day, scientists fear their language may make it possible to understand them. But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structure(结构)of their language. He thinks that's the first step in understanding what they are saying.

    Dr. Elliott's program would compare an alien language to a database (数据库)of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure. Language has to be structured in a certain way, or it will be harder to use, he told New Scientist magazine.

    Research had shown that it is possible to know if a signal(信号)carries a language rather than a picture or music. Dr. Elliott has gone a step further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr. Elliott has set up a library of the sentence structures of 60 human languages.

    If a message is received from outer space, it could be compared against this database. Scientist would then be able to see if ti's similar to any human language, or a mix of the language.

    However, Dr. Elliott also said that in order to translate what the aliens are actually saying, it may still be necessary to have a code book.

(1)、Why did Dr. Elliott come up with the program?
A、To learn more about outer space. B、To develop a new language. C、To help translate the messages for aliens. D、To compare an alien language to human languages.
(2)、According to Dr. Elliott, what's the first step of understanding an alien language?
A、Coming up with a program. B、Knowing a structure. C、Understanding aliens. D、Discovering aliens.
(3)、What does paragraph 4 mainly tell us?
A、Some necessary conditions for making the program work. B、Dr. Elliott's findings about different kinds of languages. C、Three important functions of the program. D、The number of sentence structures of human languages.
(4)、How does the program work when it receives a message from aliens?
A、Mix the message with 60 human languages. B、Translate the message and send it to the database. C、Pick out the sentence structure and translate it. D、Compare the message to the database of 60 human languages.
(5)、What can we infer from the story?
A、Not all languages have their own structure. B、The structure of alien languages is similar to that of human languages. C、To translate alien languages, there is much work to do. D、Alien languages are signals carrying pictures and music.

    Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.

    The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedrals and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee.

    Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests—eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

    About 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking(徒步)there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream(防晒霜)makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.
