[left]Part One: Reading
A/ Comprehension
A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
It’s pretty fair to say black holes are hungry all of the time and they are always wondering where their next galactic meal is coming from. Quite recently in December 2011, astronomers have noticed that our Galaxy’s black hole has set its sights on a nearby cloud of dust and gas. The scientists who have been watching this cloud for the past seven years with huge telescopes in Chile, South America, have noticed that not only is this cloud moving in the direction of the black hole, but it has also doubled in speed reaching more than 8 million kilometres per hour - now that is pretty fast! Astronomers think that this super-massive black hole will get its meal in a couple of years' time. But what happens when it does? Well, seeing as our strange friend has no manners, it is very likely to belch out very powerful beams of high energy X-ray radiation when it has finished eating - just like the X-rays you might have had at the dentist, but much more powerful!
