听力原文: The eight elephants from Thailand destined for zoos in Sydney and Melbourne are due to arrive later this year.
Wildlife campaigners have insisted that scientific evidence has proved that elephants in zoos don't breed well and suffer a wide range of health problems. On top of that, it's claimed they die at a younger age than those living in the wild or kept in parks.
The government in Canberra is allowing these Asian elephants into Australia as part of a conservation program that it believes will help safeguard the species. The population of these magnificent animals has been reduced over the past century. It's estimated that fewer than 34,000 now remain across a dozen countries.
What can we know about the elephants in zoos?
A.They generally breed well.
B.They may not suffer health problems.
C.They may die relatively young.
D.They are cleverer than the wild elephants.

听力原文: A little airplane has given new meaning to the term "going hyper".
The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. That's about 5,000 miles per hour. At this speed, you'd get around the world-- flying along the equator-- in less than five hours.
The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine. Actually, engineers have been experimenting with such an engine since the 1960s.
For an engine to bum fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. This special engine goes as fast as a rocket, but it doesn't have to carry its own oxygen supply.
Its design allows it to extract oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion flames.
A booster rocket carried the Hyper-X to an altitude of about 100,000 feet for its test flight. The aircraft's record-beating flight lasted just 11 seconds.
In the future, engineers predict, airplanes equipped with such engines could transport cargo quickly and cheaply to the edge of space. Hypersonic airliners could carry passengers anywhere in the world in just a few hours.

听力原文: The dollar dipped against the euro and the yen on Monday in the wake of weak U. S. jobs data, although the euro remained vulnerable due to worries about the political and economic outlook of the European Union.
The greenback was sold off after weak U.S. jobs figures on Friday but the euro remained close to 8-month lows after France and the Netherlands rejected the EU constitution in referendums last week.
"It's been one-way news in favor of the dollar apart from Friday's job data... We're seeing a bit of a move back today but it's not that convincing. Such is the weight of bad news on the euro," said Ian Gunner, head of foreign exchange research at Mellon Bank.
U.S. jobs growth in May was the worst in 21 months, data showed on Friday, coming after figures last week showed manufacturing activity was the slowest in almost two years.
By 0750 GMT, the euro stood at $1.2266 against the dollar, up a quarter of a percent from late New York levels on Friday and a cent above last week's 8-month low of $1.2157. The euro was little changed against the yen.
The dollar was also down a quarter of a percent against the yen at 107.29 yen.
Eurozone finance ministers meet in Luxembourg on Monday and Tuesday in the face of uncertainty over further European political and monetary integration following the two "no" votes.
Rejection of the charter at the referendums, along with the region's poor growth prospects, helped push the euro down almost 3 percent against the dollar last week.
Britain's foreign secretary was expected to announce on Monday the country was shelving plans for a referendum on the EU constitution, one step short of publicly declaring it dead.
The euro wobbled after European Central Bank Chief Economist Otmar Issing was quoted as saying that policy strategy does not rule out an interest rate cut.
A cut in rates would further underscore the dollar's interest rate advantage over the euro. U.S. rates stand at 3.0 percent compared to 2.0 percent in the euro zone.
According to the news item, ______.
A.both the dollar and the euro were strong
B.both the dollar and the euro were weak
C.the dollar was strong while the euro was weak
D.the dollar was weak while the euro was strong

听力原文:Italian scientists have raised new health concerns about the safety of using mobile phones, with research showing radio waves from the handsets makes cancerous cells grow more aggressively. When Fiorenzo Marinelli and his colleagues at the National Research Council in Bologna exposed leukemia cells in the laboratory to 48 hours of continuous radio waves they initially killed the cancer cells but then made the surviving tumor cells replicate more rapidly.
We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively.
The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors.
The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively.
What is the speaker's main topic?
A.Effects of using mobile phones on healthy human cells.
B.Risks of developing cancer involved in the use of mobile phones.
C.Damage to healthy cells caused by the use of mobile phones.
D.The potential health hazards of mobile phones on humans.

No longer children in the traditional sense, the report says adolescents still need positive support and guidance and the opportunity to finish school. Breck Ardery, VOA News, at the United Nations.
