To begin with,"muzak"(音乐广播网 )was intended simplyto createasoothing(安慰)atmosphere.Recently,however,it's ecome big business —thanks in part to recentresearch.Dr.Ronald Milliman,an American marketing expert,hasshown that music can boost sales or increase factory roduction by as much as a third.But,it has to be light music.A fast one has no effect atall on sales.Slow music can increase receipts by 38%.This isprobably because shoppers slow down and have more opportunityto spot items they like to buy.Yet,slow music isn't alway sanswer.Dr.Milliman found,for example,that in restaurants slowmusic meant customers took longer to eat their meals,whichreduced overall sales.So restaurants owners might be welladvised to play up-tempo music to keep the customers moving—unless of course,the resulting indigestion leads tocomplaints!

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.
