TEST FOR 8-TH FORM STUDENTS
Directions: In this test you will read five texts. Each text is followed by tasks. For each task you will choose the best possible answer from four answers (A, B, C, D).
Text I Amazing Black Holes
How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars.
You can see even more with a telescope. You might see stars where before you only saw dark space. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.
But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're invisible. They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.
As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe.
Imagine if the Earth were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump — the force called gravity. A black hole is so tightly packed that its gravity sucks in everything — even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness.
So the next time you stare up at the night sky, remember: there's more in the sky than meets the eye! Scattered in the silent darkness are black holes — the great mystery of space.

Something Was Wrong
One morning John Sullivan found himself walking along a street downtown. He could not explain what he was doing there, how he got there, or where he had been earlier. He didn't even know what time it was. He saw a woman walking towards him and stopped her. "I'm afraid I have forgotten my watch" he said, and smiled. "Can you please tell me the time?" When she saw him, she screamed and ran.
Then John noticed that other people were afraid of him. When they saw him coming, they flattened themselves against a building, or ran across the street to stay out of his way. "There must be something wrong with me," John Sullivan thought. "I'd better go home." He waved down a taxi, but the driver took one look at him and sped away.
John Sullivan did not understand what was going on, and it scared him. "Maybe somebody at home can come and get me," he said to himself. He found a public telephone and called home for his wife, but a voice he did not recognize answered the phone.
"Is Mrs. Sullivan there?" he asked.
"No," the female voice replied.
"Well, where is she then and what are you doing at my house?" John retorted.
The voice indignantly responded, "She is at her husband's funeral. Mr. Sullivan was killed yesterday in an auto accident downtown; I'm looking after the house until she returns. And who are you?"
