The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?
1．What is mainly described in the passage?
A．A historic discovery . B．An event of imagination
C．A research on space . D．A scientific adventure.
2．When the first piece hits the South Atlantic, it causes ________ .
A．an earthquake B．damages to cities C．an Earth explosion D．huge waves
3．Why can’t the northern half of the earth escape for long ?
A．Because the land is covered with water
B．Because the light and heat from the sun can not reach the earth .
C．Because people there can not live at the temperature of zero .
D．Because wars break out among countries .
4．By giving the example of dinosaurs , the author tries to prove ________ .
A．animals could not live in the cold climate
B．what happened 65 million years ago was an invented story
C．the human beings will die out in 2094
D．the Earth could be hit by other objects in space
第三节：阅读理解（共25小题; 每小题2分, 满分50分）
It was 3:12 a. m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling（爆裂声）of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island.
With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn (草坪).
The nine-year-old raced back into the house and upstairs to his mother’s room. He found it impossible to woke her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, “acted with all the self-control of a trained adult.”
On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.
First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.
He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor?
Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mother’s room. Tying one end of the string to her hand he ran back, laying out the string as he went, through the hall and back out into the garden.
Minutes later he was telling fire chief John Coughlan: “The string will lead you to mother.” Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor.
