    Section A

    warming up

    1. vaccinate effects

    2. countdown lift off International Space Station

    3. fired orbit

    4. stem cell

    5. DNA

    6. global warming

    7. fossilized dinosaurs

    8. mummified

    9. Nobel Prize Big Bang Big Bang

    10. verified solar outmost

Section B

    1. B 2.A 3.A 4.C 5.D

Tapescript:

    1. The first of three spacewalks for the Shuttle Atlantis crew is underway. NASA spokesman

    Kyle Herring tells us that two of the astronauts began installing a new 35,000-pound addition

    to the space station.

    2. United Nations scientists have cast doubt on links between deforestation and the kind of

    devastating floods seen most recently in Central America.

    3. A new report has warned that the impact of global warming could push some species of birds

    mammals and reptiles towards extinction as they become unable to follow their usual

    migration patterns.

    4. Astronomers at the American space agency NASA say they have detected the light from the

    first stars created in the universe. Writing in the journal Nature, they say the stars were born

    more than 13 billion years ago, not long after the birth of the universe itself. 5. Astronomers are voting today on new guidelines that will define what is a planet. Their

    decision could downgrade Pluto from a planet to a dwarf, a step below Earth and the seven

    other planets. Planet Pluto is smaller than Earth’s moon.

Section C

    Item 1

    1. F, D 2. E 3. J 4. G 5. A

Tapescript:

    China has been setting out its plans for further space missions hours after its second manned space flight ended successfully. A senior official said the next manned mission in 2007 would include a spacewalk. The astronauts would develop the ability to dock with other spacecraft. In the latest mission, two astronauts arrives safely back on Earth after five days when their Shenzhou VI capsule touched down in Inner Mongolia. They were given a rapturous reception in Beijing at a

    ceremony presided over by the country’s defense minister. The flight comes two years after China’s first manned foray into space. BBC News.

Item 2

    Task 1

    1. F 2.T 3.F 4.T 5.T

Task 2

    1. indicates while driving as dangerous as while drunk 2. over legal limit in their blood

    3. direct comparison established unacceptable debating

Tapescript:

    Research in the United States indicates that people using mobile phones while driving are just as dangerous as those who drive while drunk. Scientists from the University of Utah used a simulator to compare drivers using phones with others who were over the U.S. legal limit for alcohol in their blood. Jumi Giverin reports.

     The research ahs concluded that driving while talking on the phone seemed to be as bad as or even worse than drunk driving. Doing either makes drivers more than five times more likely to have an accident, they say. One of the researchers, Professor Frank Drews, told the BBC that they wanted to make this direct comparison, because most societies have already established that the risk from drunk driving is unacceptable, but are still debating mobile phone use.

Item 3

    1. The world’s first cloned dog

    2. Dogs are considered among the most difficult animals to clone.

    3. Dogs suffer from similar diseases to humans.

    4. It’s not a business of cloning pets but a business of trying to answer whether stem cells can

    cure diseases.

    5. Autism, Alzheimer’s, dementia and diabetes

Tapescript:

    The world’s first cloned dog has been born in South Korea in an experiment which scientist believe will help tackle human disease such as dementia and diabetes. It is an Afghan hound called Snuppy. Dogs are considered among the most difficult animals to clone. But the scientists of Seoul National University say that as dogs suffer from similar diseases to humans, Snuppy will be a valuable research model. Jerald Chaplin is one of the team.

     “We are not in the business of cloning pets; we are in the business of trying to answer whether

    stem cells can cure diabetes and whether stem cells can help us understand the root causes of diseases like autism or early onset Alzheimer’s.”

Section D

    The future of EU Stem Cell Research Remains Uncertain

    The U.S. More President Bush (1) vetoed federal funding for the research in the United

    States

    Agenda of the EU Discussion of (2) financing research on (3) embryonic stem cells.

    Meeting

    Opposition to the EU Countries like (3) German, Austria and Slovakia are against the

    funding research, arguing that the (5) embryos the stem cells come from are

    (6) potential human beings. They also (7) object funding research

    which is not allowed in their own countries.

    Stem Cell Research in The EU currently finances such work (8) under strict conditions, but

    EU the (9) approval of the entire research program budget may be (10)

    delayed because the opposition may have enough votes.

Tapescript:

    European Union ministers are meeting later on Monday in Brussels to discuss financing research on embryonic stem cells a week after President Bush vetoed federal funding for the research in the United States. The EU currently finances such work under strict conditions, but some member states are opposed to it. Alex Krueger reports from Brussels.

    The funding for stem cell research is part of the EU science program for the next seven years. The EU currently funds stem cell research but under strict conditions. A number of countries are opposed, including German, Austria and Slovakia. They argue that the embryos the stem cells come from have the potential to become human beings and therefore it’s wrong to use them for experimental purposes. They also object funding research which is not allowed in their own countries. They may have enough votes to delay approval of the entire research program budget.

Item 2

    Task 1

    1. A 2.C

    Task 2

    1. F 2.T 3. T 4.T 5.F 6. F

Tapescript:

    After three years in space, Europe’s first moon mission ended early this morning. The SMART-1 spacecraft crashed as planned on a lunar plain. From Berlin, NPR’s Emily Harris reports.

     SMART-1 landed with a small flash on a part of the moon called “ The Sea of Excellence”. Its flight lasted a year longer than originally planned. European space officials say the mission was so successful they wanted to allow it more time to orbit the moon after a slow journey to get there. SMART-1 sent back to Earth high-resolution photographs and detailed data about the chemical composition of the moon surface. Scientists hope the data will help test a theory that the moon was formed after Earth and a smaller planet collided 4.5 billion years ago. The mission also tested an ion propulsion engine, using solar power to positively charge Xenon gas atoms which were then

    spat out of the craft. The acceleration is relatively slow, but uses little fuel. SMART-1 ran out of gas, but by then was within the moon’s gravitational pull. Emily Harris, NPR News, Berlin.

Item 3

    1. Stormy weather may delay the U.S. space agency NASA’s first space shuttle launch in nearly

    a year.

    2. They waved and gave a cheerful thumbs-up sign as they headed to the launch pad. 3. They stopped the countdown just minutes before the scheduled launch.

    4. Two; NASA last launched the shuttle in July,2005

    5. It disintegrated on reentry to the earth’s atmosphere three years ago, killing all seven

    astronauts on board.

Tapescript:

    Stormy weather may again force the U.S. space agency NASA to delay the first space shuttle launch in nearly a year. Weather problems also blocked Saturday’s scheduled launch of the

    Discovery shuttle. From Kennedy Space Center, VOA’s Cindy Saint reports.

    Discovery’s seven crew members waved and gave a cheerful thumbs-up sign as they headed to

    the launch pad. The astronauts were then strapped into the space shuttle which was fueled and ready for take-off. But storm clouds lingered in the launch zone, prompting NASA officials to stop the countdown just minutes before the scheduled launch. Launch director Mike Leinbach announced the delay.

    “We’re not gonna make it today. So, I appreciate your support, both from the crew and the whole launch team and the team worldwide trying to get this vehicle off the ground today, but it’s not a good day to launch the shuttle. So we are gonna try again tomorrow.”

    The delay was a disappointment for the U.S. space agency, which last launched the shuttle in July, 2005. Discovery’s mission will be only the second launch since the space shuttle Columbia disintegrated on reentry to the earth’s atmosphere three years ago, killing all seven astronauts on

    board. Cindy Saint, VOA News, Washington.
