The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.
An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill(钻孔) deep in the side of a sandstone mountain. Temperatures in the area never rise above 0ºC. The seeds will be protected behind walls a meter thick and high-security door.
The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0ºC. The cold weather would protect the seeds even if the air could not be replaced.
Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.
53.The project is meant to ______.
A.increase the world’s food output in the future
B.carry out some scientific experiments on plant genes
C.build an exhibition centre of the world’s plant seeds
D.protect crop seeds from dying out in case of possible disasters

A.The government of Norway will perform the project alone.
B.Seeds to be collected there were produced ten thousands years ago.
C.Spitsbergen is chosen because it is free of the nuclear war forever.
D.Temperature is a major consideration when choosing the storage place.
55.We can infer from the text that _______.
A.Norway had meant to build the storage centre about 20 years before.
B.The storage center will greatly promote world agriculture
C.People will get newly-developed seeds from the center every year.
D.There haven’t been any seed storage centres in the world before.
56.What is probably the best title of the passage?www.
A.The Best Place to Store Seeds B.Noah’s Ark(诺亚方舟)of Plant Seeds in Plan
C.Concerns of World Food Supply D.A New Way to Feed the World

The first MP4 player was born years ago. Soon many music fans were wondering how fantastic it is! If you have been into technology enough, perhaps you may have a knowledge of the MP4. If not, you do need to know something before buying one, even if you are familiar with MP3. MP3 is the CD-like disc with greater capacity. How about MP4? This small digital product will really enrich the joy from listening to music. You can even feel the “touch” of music to your soul!
Now, some similar digital products advertised as “MP4 player” are simply MP3 players, which do not play video and MPEG format and also lack other particular functions. These products confuse some buyers, as they may think the “MP4” players simply mean they can do more than MP3.
What is MP4?
It is a multimedia container. It is not only used to store digital audio and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles and pictures. As a most modern container format, it allows streaming over the Internet.
With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality. By installing DVD-MP4 software, you can transfer particular music from a DVD to an MP4 video file. It really excites your listening music experience.
Then, there is MP4 advanced and you can set your own collection of all the programs—TV shows, games, and music. You can even see movies which are still running in cinema. What else digital product could you possibly ask for?
