millennia. Ex. B: Listen again and fill in the blanks.
Scientists have produced evidence showing dramatically that the current temperature rise there is highly unusual. For most of the last two thousand years, the Arctic slowly cooled, a consequence of variations in the Earth’s orbit.
But over the last century, the cooling abruptly reversed, and the region is now warmer than at any time in the 2,000 year record. Writing in the journal Science, the researchers say this shows how quickly the Arctic responds to climatic changes.
News Item 2
Ex. A: Listen to the news and complete the summary
This item is about WWF's accusation against European toilet and tissue paper manufacturers of contributing to global deforestation by not using enough recycled material.
Ex. B: Listen to the news again and answer the questions. 1. How many trees are being discarded as tissue paper each day? More than a quarter of a million trees. 2. What did the report find?
The report found alarmingly low levels of recycled fibers in the vast

majority of products by European toilet and tissue paper manufacturers.
3. Where are the fibers used by European toilet and tissue paper companies taken from?
The fibers are taken from natural forests in South Africa, Asia, Europe and across the Americas.
4. What have most of the toilet and tissue paper manufacturers failed to do?
Most of the companies have failed to take effective measures to prevent illegal or controversial timber from being used in their products.
Script of News Item Two:
The international conservation group, WWF, has accused European toilet and tissue paper manufacturers of contributing to global deforestation by not using enough recycled material. A spokesman said more than a quarter of a million trees were in fact being flushed down toilets or discarded as rubbish each day.
The report found alarmingly low levels of recycled fibers in the vast majority of products and said the fibers were instead being taken from natural forests in South Africa, Asia, Europe and across the Americas. Using virgin forest to make toilet paper, says the report, is wasteful and

unnecessary. The report also warns that illegal and unsustainable logging and conflicts over land rights still exist in many of these areas and that all but one of the companies have so far failed to take effective measures to prevent illegal or controversial timber from being used in their products. News Item 3
Ex. A: Listen and summarize the news item
This news item is about the warnings from specialists that climate change can drive some species of migrating animals towards extinction.
Ex. B Listen to the news and complete the following outline
Findings: Climate change can drive some species of migrating animals towards extinction. Reason: Birds, mammals and reptiles are finding it increasingly difficult to follow their usual migrating patterns. Examples:
1. The spreading Sahara Desert could make it impossible for swallows to make the epic journey from Southern Africa. 2. Rising sea levels will destroy many coastal habitats for turtles and wading birds.
3. Warmer oceans could lead to some turtle species becoming entirely female. Script of News Item 3

Scientists are warning that climate change could drive some species of migrating animals towards extinction. A report by European ornithologists and zoologists say that birds, mammals and reptiles are finding it increasingly difficult to follow their usual migration patterns.
This report by ornithologists and zoologists warns that global warming will cause increasing problems for many migrating species. For example, the spreading Sahara Desert could make it impossible for swallows to make their epic journey from Southern Africa, and rising sea levels will destroy many coastal habitats for turtles and wading birds. The study even suggests that warmer oceans could lead to some turtle species becoming entirely female. The selection of sex is closely linked to sea temperature.

Money, Fame, Power Don't Motivate Most Workers
In his new book, titled Drive, author Daniel Pink says there's a big gap between what science knows and what business leaders know about how to motivate a workforce.
Pink says most businesses operate today on the carrot-and-stick system of rewards and punishments. Employees are rewarded for good

performance, and penalized for performing badly.
According to Pink, the carrot-and-stick approach usually works well in situations where workers are performing simple, routine tasks, like checking products on an assembly line or packing boxes. But for jobs that require creativity, and deeper, more complex thinking, such as writing or designing, employers need to take a different approach
Pink says it is important to recognize people are not as motivated by external factors like cash rewards as they are by things that interest them. He calls these intrinsic or internal motivators. “Intrinsic motivator is doing something for the sake of the activity itself. So you play the banjo because you like to play the banjo. Extrinsic motivator is doing something in order to get a reward. So I might work really hard because whoever with the most sales will get a $100 gift card.”
According to Pink, intrinsic motivators can be broken down into three components: The first is autonomy, that is, self-direction. Another one is mastery, that is, our desire to become better at something that matters, and finally, purpose, which is to do what we do in service of something larger than ourselves.
