1. A European spacecraft took off today to spearhead the search for another
"Earth" among the stars.
2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from
the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm.
3. Corot, short for convection rotation and planetary transits, is the first
instrument capable of finding small rocky planets beyond the solar system. Any
such planet situated in the right orbit stands a good chance of having liquid
water on its surface, and quite possibly life, although a leading scientist
involved in the project said it was unlikely to find "any little green men".
4. Developed by the French space agency, CNES, and partnered by the European
Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will
monitor around 120,000 stars with its 27cm telescope from a polar orbit 514
miles above the Earth. Over two and a half years, it will focus on five to six
different areas of the sky, measuring the brightness of about 10,000 stars every
512 seconds.
5. "At the present moment we are hoping to find out more about the nature of
planets around stars which are potential habitats. We are looking at habitable
planets, not inhabited planets. We are not going to find any little green men,"
Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since
its inception, told the BBC Radio 4 Today programme.
6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could
develop an atmosphere and, if they are the right distance from their parent
star, they could have water".
7. To search for planets, the telescope will look for the dimming of
starlight caused when an object passes in front of a star, known as a "transit".
Although it will take more sophisticated space telescopes planned in the next 10
years to confirm the presence of an Earth-like planet with oxygen and liquid
water, Corot will let scientists know where to point their lenses.
8. Measurements of minute changes in brightness will enable scientists to
detect giant Jupiter-like gas planets as well as small rocky ones. It is the
rocky planets - that could be no bigger than about twice the size of the Earth -
which will cause the most excitement. Scientists expect to find between 10 and
40 of these smaller planets.
9. Corot will also probe into stellar interiors by studying the acoustic
waves that ripple across the surface of stars, a technique called
"asteroseismology".
10. The nature of the ripples allows astronomers to calculate a star’s
precise mass, age and chemical composition.
11. "A planet passing in front of a star can be detected by the fall in light
from that star. Small oscillations of the star also produce changes in the light
emitted, which reveal what the star is made of and how they are structured
internally. This data will provide a major boost to our understanding of how
stars form and evolve," Prof Roxburgh said.
12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting
a star other than the Sun - more than 200 others have been found by ground-based
observatories.
13. Until now the usual method of finding exoplanets has been to detect the
"wobble" their gravity imparts on parent stars. But only giant gaseous planets
bigger than Jupiter can be found this way, and they are unlikely to harbour
life.
14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five
interlinked space telescopes that will not only spot small rocky planets, but
analyse their atmospheres for signs of biological activity.
15. At around the same time, the US space agency, Nasa, will launch
Terrestrial Planet Finder, another space telescope designed to locate Earth-like
planets.
Choose the appropriate letter from A-D for question 1.
1. Corot is an instrument which
(A) can help to search for certain planets
(B) is used to find planets in the orbit
(C) can locate planets with human beings
(D) can spot any planets with water.
Do the following statements agree with the information given in the reading

TRUE if the statement agrees with the information
FALSE if the statement contraicts the information
NOT GIVEN if there is no information on this in the passage
2. Scientists are trying to find out about the planets that can be
inhabited.
3. BBC Radio 4 recently focuses on the broadcasting of Corot.
4. Passing objects might cause a fall in light.
5. Corot can tell whether there is another Earth-like planet.
Based on your reading of the passage, complete the sentences below with words

The Guardian
1. Consumers are to be presented with two rival new year advertising
campaigns as the Food Standards Agency goes public in its battle with the
industry over the labelling of unhealthy foods.
2. The Guardian has learned that the FSA will launch a series of 10-second
television adverts in January telling shoppers how to follow a red, amber and
green traffic light labelling system on the front of food packs, which is
designed to tackle Britain’s obesity epidemic.
3. The campaign is a direct response to a concerted attempt by leading food
manufacturers and retailers, including Kellogg’s and Tesco, to derail the
system. The industry fears that traffic lights would demonise entire categories
of foods and could seriously damage the market for those that are fatty, salty
or high in sugar.
4. The UK market for breakfast cereals is worth ￡1.27bn a year and the
manufacturers fear it will be severely dented if red light labels are put on
packaging drawing attention to the fact that the majority are high in salt
and/or sugar.
5. The industry is planning a major marketing campaign for a competing
labelling system which avoids colour-coding in favour of information about the
percentage of "guideline daily amounts" (GDAs) of fat, salt and sugar contained
in their products.
6. The battle for the nation’s diet comes as new rules on television
advertising come into force in January which will bar adverts for unhealthy
foods from commercial breaks during programmes aimed at children. Sources at the
TV regulators are braced for a legal challenge from the industry and have
described the lobbying efforts to block any new ad ban or colour-coded labelling
as "the most ferocious we’ve ever experienced".
7. Ofcom’s chief executive, Ed Richards, said: "We are prepared to face up to
any legal action from the industry, but we very much hope it will not be
necessary." The FSA said it was expecting an onslaught from the industry in
January. Senior FSA officials said the manufacturers’ efforts to undermine its
proposals on labelling could threaten the agency’s credibility.
8. Terrence Collis, FSA director of communications, dismissed claims that the
proposals were not based on science. "We have some of the most respected
scientists in Europe, both within the FSA and in our independent advisory
committees. It is unjustified and nonsensical to attack the FSA’s scientific
reputation and to try to undermine its credibility."
9. The FSA is understood to have briefed its ad agency, United, before
Christmas, and will aim to air ads that are "non-confrontational, humorous and
factual" as a counterweight to industry’s efforts about the same time. The
agency, however, will have a tiny fraction of the budget available to the
industry.
10. Gavin Neath, chairman of Unilever UK and president of the Food and Drink
Federation, has said that the industry has made enormous progress but could not
accept red "stop" signs on its food.
11. Alastair Sykes, chief executive of Nestlé UK, said that under the FSA
proposals all his company’s confectionery and most of its cereals would score a
red. "Are we saying people shouldn’t eat confectionery? We’re driven by
consumers and what they want, and much of what we do has been to make our
products healthier," he said.
12. Chris Wermann, director of communications at Kellogg’s, said: "In
principle we could never accept traffic light labelling."
13. The rival labelling scheme introduced by Kellogg’s, Danone, Unilever,
Nestlé, Kraft and Tesco and now favoured by 21 manufacturers, uses an
industry-devised system based on identifying GDAs of key nutrients. Tesco says
it has tested both traffic lights and GDA labels in its stores and that the
latter increased sales of healthier foods.
14. But the FSA said it could not live with this GDA system alone because it
was "not scientific" or easy for shoppers to understand at a glance.
Questions 1-6

for each answer.

2. Where can customers find the red light labels?
3. What problem is the FSA trying to handle with the labeling system?
4. Which product sells well but may not be healthy?
5. What information, according to the manufacturers, can be labeled on
products?
6. What can not be advertised during children’s programmes?
