举一反三
An African tigerfish(老虎鱼) was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors(传闻) this kind of fish preys on(捕食) birds since the 1940s, but no one was able to catch one.
"The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University.
Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure!

C.The interesting findings happened in a lake in the afternoon. |
D.The birds were caught by the tigerfish because they were out too early for food. |
A.In a poster. | B.In a tour guide. | C.In a newspaper. | D.In a story book. |
A.The early fish gets the bird. |

Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.
What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other buildings float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.
小题1:What information can we get from the first passage?
A.It is the jet stream that affects how fast airplanes fly. |
B.Planes go slower when they are moving with the wind. |
C.It takes more time to fly from NY to London than from London to NY. |
D.The jet stream always blows from the east to the west across the Atlantic. |
A.send for | B.move quickly | C.come out | D.grow quickly |
A.buildings and other structures would float away |
B.trees and buildings would not so easily fly off |
C.something around your head would not float away |
D.everything outside buildings would fly off into space |
A.It takes seven hours to travel from London to New York. |
B.The earth is moving at a high speed. |
C.Things on the earth will float away if there’s no gravity. |
D.Things not attached to the earth would fly off in a straight line. |
A.In a research paper. | B.In a short story. |
C.In a travel magazine. | D.In a student’s book |

Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs. What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

A.kill germs | B.carry germs | C.protect germs | D.love germs |

But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless (无害的)thing.
Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired.
Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth.
Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again.
Perhaps these comets that never return have broken into pieces. For some astronomers think that shooting stars(流星) are pieces of broken comets.

A.comets are different from planets |
B.comets travel in the sky |
C.comets are much bigger than the earth |
D.comets could hit the earth |
A.long hair | B.round heads | C.round dishes | D.wide wings |
A.water | B.solid | C.gas | D.small stones |
A.心理学家 | B.艺术家 | C.天文学家 | D.考古专家 |
A.A comet is a kind of planets. |
B.Comets are all ten times as big as the earth. |
C.People can hardly see comets. |
