[00:28.29]PART Two
[00:29.17]UNIT 1
[00:30.13]In this section, you will hear everything ONCE ONLY.
[00:34.20]Listen carefully and then answer the questions that follow.
[00:38.68]Questions 1 to 2 are based on the following news.
[00:42.61]At the end of the news item,
[00:45.33]you will be given 10 seconds to answer each of the two questions.
[00:49.95]Now listen to the news.
[00:52.36]U.S. military officials say the crash late Friday
[00:58.05]occurred during combat operations in Kunar province.
[01:01.23]The CH-47 Chinook went down about 240 kilometers east of the capital Kabul,
[01:07.67]not far from the Pakistan border.
[01:10.48]Military spokeswoman Lieutenant Tamara Lawrence says
[01:14.32]an investigation is under way to determine the cause of the crash.
[01:17.91]“But it is important to note that
[01:20.22]the crash was not due to any hostile action or enemy fire.”
[01:23.81]She says the bodies of all ten soldiers have been recovered.
[01:27.65]More than 2,000 US and Afghan soldiers have been targeting
[01:31.58]Taliban insurgents in Kunar province since last month.
[01:35.07]It is one of the largest offensives
[01:37.18]since the US-led coalition ousted the Taliban from power in 2001.
[02:02.21]Question 3 is based on the following news.
[02:05.72]At the end of the news item, you will be given 10 seconds to answer the question.
[02:11.52]Now listen to the news.
[02:13.69]Before the Columbia disaster,
[02:16.44]NASA said 28 shuttle flights were needed to build the International Space Station.
[02:22.87]Now Dr. Griffin says it can be done in just 16
[02:27.05]before the fleet has to be retired in 2010.
[02:31.42]So how to achieve this feat:
[02:33.92]Well, Dr. Griffin has adopted a‘build now, use later’philosophy.
[02:39.39]Previously the plan was for astronauts to do scientific research
[02:44.42]as they constructed the station.
[02:46.51]Now there will be no time for science,
[02:49.46]all 16 missions will be geared to sending up
[02:53.61]and bolting on the various bits of the International Space Station.
[02:57.78]Many of which had been built at great expense by the Japanese,
[03:02.15]Russian and European space agencies.
[03:13.91]Questions 4 and 5 are based on the following news.
[03:19.60]At the end of the news item,
[03:22.54]you will be given 10 seconds to answer each of the two questions.
[03:27.13]Now listen to the news.
[03:29.55]There are 350,000 billion particles in this tube.
[03:34.80]So nano technology is the science of the very small.
[03:39.17]But how small is small? Well imagine I was shrunk to a 1,000 times smaller.
[03:45.74]I’d be about as big as the eye of a fly, but nano is even smaller than that.
[03:50.77]In fact, much, much smaller. Imagine I was shrunk again, this time 10,000 times.
[03:58.09]I’d be about as big as a virus, but nano is even smaller than that.
[04:02.81]You’d have to shrink me another 100 times to get the nano version of me,
[04:07.40]a billion times smaller than the real me.
[04:10.02]Industry is already building devices on that scale.
[04:13.20]Here in Cambridge they’re making very thin nano layers of a plastic
[04:17.51]that emits light when electrical current runs through it.
[04:20.71]The technology will soon be on the market,
[04:22.99]in mobile phones with very bright, energy-saving displays.
