英国新闻听力 伊朗德黑兰发生多起冲突（在线收听）

There have been renewed clashes between police and opposition demonstrators in the Iranian capital Tehran. Eyewitnesses reported that dozens of protesters were arrested in one of the city’s main squares after chanting slogans against President Ahmadinejad, the declared winner of last month’s disputed election. Our correspondent Jon Leyne reports.

Once again opposition supporters came out on the streets despite police warnings that they would be severely dealt with. Witnesses say hundreds or according to some accounts, thousands of opposition members demonstrated in Tehran. There were large numbers of riot police, but also plain-clothes security officers who infiltrated the crowds. Violence broke out and there were dozens of arrests. The opposition has also been trying a new tactic--switching electrical equipment off then on again at exactly the same time in an attempt to bring down the power grid. One Iranian who recently left the country told me there was atmosphere of defiance there which could be felt in every corner.

The Chairman of the US Central Bank Ben Bernanke says economic recovery should start gradually as the year progresses accelerating in 2010, but he said unemployment would increase. Rodney Smith reports.

Mr. Bernanke warned that rising unemployment could weaken consumer confidence in the US and harm a gradual economic recovery. On the plus side, Mr. Bernanke sees recovery starting gradually as the year progresses, accelerating through next year and into 2011. The two big threats to the fragile recovery, he indicated, could be inadequate stimulation of the economy, therefore interest rates would have to be held down, and rising unemployment which could seriously impact on consumer confidence and the capacity of consumers to stimulate demand through spending.

A Brazilian report says 5,000 adolescents are killed every year in the country's cities and towns, most of them poor and uneducated black males. The report was released jointly by the UN Children's Agency, the Brazilian government and a slum monitoring group. Brazil’s Under-Secretary for Human Rights Carmen de Olveira said the murder rate among young Brazilians was 30 times that experienced in European countries and the most of the victims had links with the drugs trade, generally as users rather than dealers.

American scientists have begun tracking the life history of some of the world’s oldest and tallest trees in California amid concerns that climate change might be causing them to die prematurely. Botanists from the University of Washington are carrying out experiments in Yosemite National Park which is home to many towering redwood trees. Dr. James Lutz, one of the researchers, says it’s a long-term project.

No one researcher can see the ultimate results of the work. I plan on monitoring this plot for, say, the next 25 or 30 years, after which I will hope turning the plot over to someone in the next generation of forest ecology and I think that the most valuable in these long-term projects is only realized after 50 or even a hundred years.

Italian newspapers who published the tapes claimed the man is Mr. Berlusconi, but the Prime Minister has already denied meeting Ms. D’Aaddario and says he has never paid for sex.

The original advert for an Israeli mobile phone company showed Israeli soldiers enjoying a game of football with unseen Palestinians behind a high concrete wall.

美国中央银行主席本·伯南克称：经济复苏应该按部就班的开始，并在2010全面展开。但是失业人数还是会有所增加。史密斯报道。

本·伯南克称，不断增加的失业人口会降低美国消费者的信心，并损害逐渐恢复的经济；另一方面，他还指出经济复苏应该按部就班的开始，在明年开始提速，并在2011年全面恢复。他指出，这两大威胁使经济恢复得不到足够的刺激，影响经济的复苏。因此必须保持低利率，不断增加的失业人口会严重影响消费者的信心，和降低消费者通过消费来刺激需求的消费能力。

美国科学家已经开始跟踪加利福尼亚州的一些世界上最古老，最高的树种，因为他们认为气候的变化会让它们有可能死于树木成熟之前。约塞米蒂国家公园是很多高大的杉树的家园，来自华盛顿大学的植物学家正在公园内进行试验。其中一个研究员.詹姆斯博士说道，这是一个长期的工程。

没有一位研究人员能够知道这项工作的结果如何。我计划用25年或30年来跟踪这个工程。之后我希望把这项工程传递给负责森林生态的下一代研究员。我想这用去50年甚至一百年才能实现的长期工程才是最有价值的。

倾巴勒斯坦的活动家已经以她们的视角拍摄了一部具有争议的以色列电视广告。评论家们说原广告没有表达出巴勒斯坦人民的真正苦难。以色列的一家移动电话公司的原广告的内容是：以色列的士兵非常享受的与隔着混凝土高墙的看不见的巴勒斯坦人民踢足球。但是巴勒斯坦的活动家他们自己拍摄的足球场景是：踢足球的人们越过约旦河西岸的以色列的障碍建筑，而色列士兵对此的反应是向他们投掷催泪弹。
