¡¾ÌâÄ¿¡¿ A villa designed to resist earthquakes with ¡°self-healing¡± cracks in its walls, thanks to nanotechnology applications with self healing polymers(¾ÛºÏÎï), is to be built on a Greek mountainside. The villa¡¯s walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material.

The Nano Manufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called ¡°Intelligent Safe and Secure Building¡±(ISSB) is funded under the EU¡¯s Sixth Framework program. This potentially life saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant(·ÀÕð)homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, ¡°What we¡¯re trying to achieve here is very exciting. We¡¯re looking to use polymers in much tougher situations than ever before on a larger scale.¡± Monitors contained in the villa¡¯s walls will be able to collect vast amounts of data about the building over time.

Wireless sensors and Leeds designed radio frequency identity tags will record any stresses and vibrations, as well as temperature, humidity and gas level. The walls are to be built from novel load-bearing steel frames and high strength gypsum board. Professor Wilkins said, ¡°If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape.¡± If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. ¡°If the house falls down, we have got hand-held devices that can be used over the rubble to pick out where the embedded(ǶÈëµÄ)sensors are hidden to get some information about how the villa collapsed.¡± Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue.

¡¾1¡¿The aim of the passage is to .

A. report a piece of interesting news

B. promote tremor-resistant homes

C. inform us of the nanotechnology development

D. tell us about a tremor resistant home

¡¾2¡¿The villa can resist earthquakes because .

A. it will be built on a special place

B. the cracks in its walls can be healed by the polymers

C. the special particles can make its walls stronger

D. the intelligent sensor network can tell people where there is a crack

¡¾3¡¿If the tremor resistant home falls down, .

A. no one can be hurt in the earthquake

B. the intelligent sensor network will stop working

C. rescue work can be done more quickly and accurately

D. a warning signal will be given to other residents

¡¾ÌâÄ¿¡¿Before she appeared on the reality show(ÕæÈËÐã) Britain¡¯s Got Talent, Susan Boyle was just an ordinary middle-aged British woman. Now all this is going to change.

She lives in a house with her cat Pebbles in a tiny Scottish town. Because of learning difficulties, she doesn¡¯t have much education. But what she does have is a very good voice. As a kid, she sang in church and choirs and school plays. For a living, she sang at local pubs.

When she took the stage on April 10th her hair was untidy and her clothes seemed just one step up from rags. The audience laughed at her.

But then she opened her mouth. A few bars into the song and the laughing audience went silent. A beautiful voice was singing I Dreamed a Dream from the musical Les Miserables. Everyone was amazed. At the end of her song, the audience jumped to their feet and applauded wildly.

Almost overnight, Susan became a household name. She won fans and millions of admirers. Her online videos have drawn over 85.2 million hits.

Susan¡¯s story proved the truth of an old saying: ¡°Never judge the book by its cover.¡± Susan may look ordinary, and doesn¡¯t have much dress sense, but she can certainly sing.

Susan¡¯s fans admire her courage, as much as they do her voice. She has experienced mockery and many disappointments, but her love for music has kept her going, which is worth anyone¡¯s respect.

¡¾1¡¿ According to the passage, Susan Boyle _______.

A. is a famous young actress

B. became famous after a show

C. used to be a good student

D. is good at dancing and has millions of admirers

¡¾2¡¿ The underlined phrase ¡°just one step up from¡± in the third paragraph probably means______.

A. far from B. close to C. different from D. the same as

A. her hair was untidy and her clothes seemed just one step up from rags

B. she looked very funny

C. she sang so well that everyone was amazed

D. she made a foolish mistake in the end

¡¾4¡¿ Susan Boyle has many fans now because of _______.

A. her beautiful face

B. her knowing how to dress

C. her good education

D. her beautiful voice and courage

¡¾5¡¿ The passage is mainly about___________,

A. how to win fans
