W: Do you think that is a good thing? Has it been a good thing for the railways, do you think, to be nationalized?
M: Oh, I think so, yes, because in general, mosts of the transports are all around. Let’s face the fact, the car are arrived the cars are here to stay. There is no question about that
W: So what’s your saying then? Is it if the railways haven’t been nationalized, they would simply have disappeared?
M: Oh, I think they would have. They are disappearing fast in America. The French railways lose 1 billion pounds a year, the German railways, 2 billion a year. But you see those governments are preparing to pour the money into the transport system to keep it going
W: So, In a sense, you call between two extremes. On the one hand, they are trying not to lose too much money, and on the other hand, you’ve got to provide the best service。
M: Yes, you are right

听力原文(SecB 第一篇)
Among global warming’s most frightening threats is the prediction is that the polar ice-caps will melt, raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded. Scientists agree that key player in this scenario is the west Antarctic ice sheet, a Brazil-size mass of frozen water that is much as 7000 feet thick. Unlike floating ice shelves which have little impact on sea level when they break up, the ice sheet is anchored to bedrock will blow the sea surface. Surrounded by open ocean, it is also vulnerable, but Antarctic experts disagree strongly on just how unstable it is. Now, new evidence reveals that all or most of the Antarctic ice sheet collapsed at least once during the past 1.3 million years, a period when global temperatures probably were not significantly higher than they are today. And the ice sheet was assumed to have been stable. In geological time, a million years is recent history. The proof, which was published last week in Science, comes from a team of scientists from Uppsala University in Sweden and California Institute of Technology who drew deep holes near the edge of ice sheet. Within samples collected from the solid substances lying beneath the ice. They found fossils of microscopic marine plants which suggest that the region was once open ocean not solid ice. As Herman Engleheart, a co-author from the California Institute of Technology says the west Antarctic ice sheet disappear once and can disappear again。

Passage2
It’s always fun to write about reserch you can actually try out yourself. Try this. Take a photo and upload it to Facebook, then after a day or so, know what URL link to the picture is and then delete it. Come back a month later and see if the link works. Chances are, it will. Facebook isn’t alone here. Researches at Cambridge University have found out nearly half of the social netwworking sites don’t delete pictures immediately when a user request they be removed. In general, photo-centric websites like Phlica were found to be better at quickly removing deleted photos upon request. Why did deleted photos deck around so long? The problem relates to the way data restored on large websites. While your personal computer only keeps one copy of a file., large-scale services, like Facebook, rely on what are called Content Delivery Networks to manage data and distribution. It’s a complex system where we render data to mutil-intermedia devices usually to speed up access to files when millions of people are trying to access the service at the same time. But because changes aren’t reflected across Content Delivery Networks immediately, ghost copies of files tend to linger for days or weeks. In the case of Facebook, the company says data may hang around until the URL link questioned is reused, which is usually after a short period of time, though obviously that time vary considerably。
Question 30 What does the speaker ask us to try out?
Question 31 What accounts for the failure of some websites to remove photos immediately?
Question 32 When will the unwanted data eventually disappear from Facebook according to the company?(周秀婷)
Passage3:
Enjoy an iced coffee, better skip dinner or hit the gym afterwards. With the Cancer Charity warning that some iced coffees contain as many calories as a hot dinner, the World Cancer Research Fund (WCRF) conducted a survey of iced coffee sold by some popular chains in Britain including Starbucks, Cafe Nero and Costa Coffee to give the calories as studies increasingly link obesity with cancer. The worst offender, a coffee from Starbucks had 561 calories, other iced coffees contained more than 450 calories, and the majority had an excess of 200. Health experts advise that the average women should consume about 2000 calories a day and a man about 2500 calories to maintain a healthy weight. Dieters in for 1000 to 1500 calories a day. The fact that there is an iced coffee on the market with over a quarter of a woman’s daily calories allowance is alarming. Doctor Rachel Thompson, science programmer manager at London-based WCRF, said in a widely reported statement, this is the amount of calories you might expect to have in an evening meal, not in a drink. The WCRF has estimated that 19 thousand cancers a year in Britain could be prevented if people lost their excess weight, with growing evidence that excess body fat increases various cancers. If you are having these types of coffee regularly. Then they will increase chances of you becoming overweight, with in turn increases your risk of developing cancer as well as other diseases such as heart disease, she added。
