The editorial team has dedicated the next English issue to the topic ‘New frontiers’. As you have already done some research on SETI, you have offered to write a report about the latest observations of the Kepler Space Telescope. This is the information you’ve collected: 31 - Analysis of the first three years of Kepler data (May 2009 to March 2012) showed a 29% increase in the number of potential Earth-like planets – compared to 2008. An independent statistical analysis of nearly all four years of Kepler data suggests that one in five stars like the sun is home to a planet up to twice the size of Earth, orbiting in a temperate environment. - The ‘circumstellar habitable zone’ (CHZ) is defined as the region around a star where water could exist on the surface of an Earth-like planet. Read two summaries of the interview with Jill. Which do you think is best? Why? a 29 If the SETI Institute detects a signal, they’ll do everything they can to make sure it isn’t a hoax. They’ll tell the world, because the signal isn’t only being sent to California. They won’t transmit back until there’s been some kind of global consensus. But some people have a fear of the unknown and others would want their story to be told. Freeman Dyson says anybody with a transmitter will send whatever signal they want – typical of our twenty-first century world. A If the SETI Institute receives a signal, they’ll first check with another telescope to make sure it’s genuine. They’ll then inform other astronomers and the world in general. They won’t send a signal back until there’s a worldwide agreement about what to say. However, it will take time to reach an agreement, and many people may decide to send their own signals independently. B How do the summaries match (or fail to match) these points? A summary should: 1 be easy to understand. 2 include all the main points of the original, without unnecessary details. 3 not include your own opinions or reactions. 4 not include any unnecessary words and expressions. 5 be written in your own words, without copying sections of the original. 6 be written in complete sentences, linked to make a paragraph. Now prepare to write a summary of the article Forget space travel … on p. 10.   Read it again to make sure you understand each paragraph.   Make notes of the main points.   Compare with a partner to see if you agree on the main points. Work alone and write your summary. Aim for about 100 words. In pairs, look at each other’s summaries and check them. Have they followed the points in 29b? Work together to improve them. b a 30 b c Nur zu Prüfzwecken – Eigentum des Verlags öbv
